HomeBlogData ScienceData Science for Supply Chain Forecasting [An Overview]
Supply chain experts in today's highly competitive market are attempting to build a unified supply chain that is efficient, productive, and flexible while also handling vast volumes of data. Supply chain practitioners often depend on historical data to estimate demand. However, with the recent introduction of machine learning algorithms, we now have new tools at our disposal that can reach remarkable prediction accuracy for a typical industrial demand dataset in a short period. This helps us to quickly attain good prediction accuracy performance. These models will be able to learn a large number of relationships, something ordinary statistical models cannot achieve.
For example, how to include supplemental data (such as current weather) into a prediction model.
Traditional statistical approaches give a forecast based on prior demand using a previously established model. The issue is that these models were unable to meet the demand that had previously been experienced. If you attempt to forecast a seasonal product using a model that utilizes double exponential smoothing, the model will fail to understand the seasonal trends. If, on the other hand, a triple exponential smoothing model is used for non-seasonal demand, the model may overfit the noise in the demand and misunderstand it as seasonality. This may be avoided if the model is not applied to non-seasonal demand. The use of data science for supply chain forecasting and data analytics to supply chain management is gaining popularity.
This is due to the fact that BDA has a wide variety of applications in SCM, such as customer behavior analysis, trend analysis, and demand forecasting. This is owing to the fact that BDA has a diverse set of applications. In this study, we investigate predictive BDA applications in supply chain demand forecasting in order to propose a classification, find gaps, and provide suggestions for future research. The categories we use to characterize these approaches and their applications in supply chain management include time-series forecasting, clustering, K-nearest-neighbors, neural networks, regression analysis, support vector machines, and support vector regression.
This study also highlights the fact that the literature on the application of BDA for demand forecasting in closed-loop supply chains is noticeably lacking, and as a consequence, it proposes prospective future research directions. Bootcamp for Data Science is for people wanting to get into this domain.
Academic research and major companies like Walmart and Procter & Gamble drove significant development in supply chain management in the 1990s. The global supply chain is experiencing another significant shift driven by Big Data and propelled by data science teams using sophisticated technologies like artificial intelligence, blockchain, and robots, even while some organizations are still on the road to applying best practices.
These developments, typically characterized by and summed up by phrases like "Industry 4.0," "Supply Chain 4.0," and "Supply Chain Digitization," promise to reduce inventory levels, automate demand forecasts, minimize lead times, and increase the reliability of production and delivery.
In a nutshell, the goal of these innovations is to boost businesses' profitability and competitiveness by making their supply chains more nimble, predictable, and cost-effective.
An important advantage of data science is the improved precision it often provides compared to traditional methods. As more data is analyzed, for forecasting methods in supply chain, the likelihood of producing reliable forecasts increases.
Management Improvements: Managing a supply chain is not simple; it needs the identification of insights that are both timely and cost-efficient. It is the goal of data science to use supervised and unsupervised learning to identify the characteristics and elements that contribute to effective management.
Increased Efficacy with Decreased Expenditure: Horizontal cooperation across different transportation and logistics networks is possible with the use of machine learning and data science techniques. This not only improves supply chain efficiency, but also lessens potential dangers.
Statistical science and machine learning excel in recognizing patterns, whether they are based on data insight or visual data. Therefore, it is useful for checking the condition of the supply chain's material assets.
Machine learning can anticipate sales and demand for new products when a company introduces them to the market. Statistical models aid in refined demand forecasting by factoring in a wide range of market drivers.
The role of forecasting in supply chain is vast. Improvements to the Supply Chain as the market evolves, so do the methods for managing it. As a result, there is always room to cut supply chain costs by minimizing things like resource waste, inventory bottlenecks, and shortage concerns. In this context, machine learning may provide useful information for optimizing warehousing, logistics, stock, and production planning.
Finally, machine learning considers many elements that impact manufacturing and production activity, such as inventories, limitations, equipment, warehousing, etc., resulting in well-managed output. This aids in enhancing the workflow, decreasing the latency, and achieving a healthy equilibrium between compliances and restrictions. Check out Best Data Science courses in India for an in-depth understanding of the topic.
There is no one supply chain process that can be treated as such. Both, however, are inextricably linked and indispensable to one another. A breakdown at any link in the chain may cause costly delays and additional expenses.
Supply chain data scientists do analyses to help with forecasting and risk management. Some examples of data science's potential use in SCM are shown below.
For most factories, finished commodities begin as raw materials. Fruits, flowers, and latex are examples of raw materials derived from plants; leather, wool, and milk come from animals; and minerals are mined (crude oil, metals, minerals).
Using data analytics, materials management functions including sourcing, quantity, storage, security, and quality control may be improved. The report also evaluates the effect of inputs on production and assesses the quality of final goods.
The term "procurement" refers to the process through which products and services are acquired from vendors. Finding vendors, haggling over prices, sending out purchase orders, paying for goods, keeping tabs on deliveries, and keeping records are all common parts of the supply chain process.
Collecting and analyzing procurement data for the purpose of gaining business insights and making more informed decisions is the primary focus of procurement analytics. It is useful to keep an eye on the purchasing procedure and evaluate aspects like the price of supplies, the quality of products, and the rapport with suppliers.
Ships, trucks, trains, and planes are all used to transfer goods through the supply chain. The optimum mode of transportation may be predicted and visualized with the aid of data scientists. Shipment scheduling, shipping routes, backhaul routes, and transport compliances are all calculated using different prediction algorithms.
Data analytics may help manufacturers that operate their own vehicle fleets save expenses and boost productivity. Data on fuel consumption may be gathered and analyzed with the use of telematics devices and on-board computers. Companies may save money on gasoline by encouraging safe driving practices and stocking up on fuel-efficient vehicles.
Companies that source their materials internationally are often subject to trade restrictions. Tariffs, for instance, are levies imposed on imported products. Products made from certain raw materials may be more expensive than they would be without government limitations, even if those commodities could be purchased for less elsewhere.
The impact of a price hike or cut on a company may be better understood with the use of data analysis. In addition, it learns from the past and gathers information about the clients. The information is then used to set prices that are commensurate with the product's worth and boost revenue.
By analyzing past sales data in conjunction with real-time data, data scientists may make predictions about the level of demand in the future. They often utilize machine learning and predictive analytics to assess the variables driving client demand and their possible influence on the company.
Better company choices may be made with the support of precise demand forecasts and planning. It provides insight into how demand at different distribution points might be affected by factors including customer tastes, competition moves, and the company's own production and advertising initiatives.
The correct inventory, the right quantity, and the proper warehouses may all be determined with the use of data analytics. This simplifies material and product demand forecasting, inventory management, and keeping up with supply.
Supply chain management data scientists can provide light on product and sales channel performance in addition to consumer behavior. This aids businesses in avoiding shortages and surpluses, expediting orders, maximizing revenue and profit, and boosting customer happiness.
It's possible for certain aspects of supply chain management to undergo rapid shifts. This might be due to things like a lack of physical labor, a change in the weather, traffic, or congestion at ports and roads. A reliable supply chain, however, will have the resources to optimize, reroute, and address problems rapidly.
With the use of data analytics, bottlenecks and delays in the supply chain's activities may be anticipated and planned for. Organizations may head off potential problems in the supply chain by taking precautions before they are caused by external forces.
To succeed in today's market, the supply chain must be considered not only an operational but a highly strategic emphasis due to the increased volatility, scarcity, and intense rivalry for customers' attention. The role of demand forecasting in the supply chain is huge. Profit margins may be further eroded by supply chain interruptions due to the increased cost of inputs such as gasoline and commodities, labor, and tariffs. Long-term aberrant occurrences, such as COVID, may also have a role, such as international or political pressure, climate change, and extreme weather. The capacity to anticipate supply chain problems before they arise, diagnose fundamental causes, and prioritize based on business value is essential for companies to thrive in times of unpredictability and upheaval.
Fortunately, we live in an era of unparalleled data availability, allowing practitioners (if they have the skills) to create meaningful, practical, and lucrative solutions based on cutting-edge analytics and data science. Explanatory and diagnostic A complete image of your supply chain's history can be painted with the help of analytics and reporting, paving the way for machine learning-based predictive and prescriptive models. With the help of supply chain data science, you can optimize based on what you can control and anticipate what you can't, allowing you to concentrate on the now what, which is data-driven decision making.
The machine learning algorithm will be asked the following question in order to produce a prediction:
If we look at demand during the last n periods, what can we expect it to be like in the period(s) to come?
The model will be trained by being fed data in a structured fashion:
In order to simplify the table, let's look at an example (based on a quarterly forecast):
Our forecasting challenge consists of showing our machine learning system snippets of our historical demand dataset as inputs, along with the subsequent demand observation for each snippet. As we saw above, the system can predict future demand by analyzing trends in the previous four quarters. If the previous four demand observations were 5, 15, 10, and 7, the algorithm will learn that the next demand observation will be 6, and it will make a forecast of 6.
There are essentially two possible responses to this proposition from the general population. Either "it is just impossible for a computer to look at the demand and make a forecast," or "as of today, the humans have nothing left to do." They're both completely incorrect.
Machine learning, as we shall see, can provide highly precise forecasts. Many questions remain for us, the humans operating the machines: What information should we provide the algorithm so that it can learn the right connections?
A plethora of fascinating data science uses (and difficulties) exist. Many areas of the supply chain, such as demand forecasting, distribution, contact centers, procurement, and pricing, stand to be disrupted by some of the most promising applications now being developed by today's students.
Impact on Demand Forecasting
Companies may use predictive and prescriptive analysis to increase the precision of demand forecasting as they gain the capacity to incorporate more data at a finer resolution. This may be done in several ways, such as by pushing forward developments in optimizing forecasting horizons, using cutting-edge forecasting algorithms, or determining the best aggregation levels for making predictions.
Companies in the modern day need to understand the impact of marketing campaigns from consumers, rivals, and internal departments on demand across all distribution channels. Data Science is one proven forecasting techniques in supply chain.
Product innovation, trends (e.g., demographic shift), and government (e.g., tariffs or new regulations) are just a few examples of external variables that are continually influencing demand behavior and forcing businesses to reevaluate their product offerings.
Better demand forecasting leads to more efficient production scheduling and better inventory safety and cycle stock levels (e.g., more accurate data and automated parameter adjustments).
Impact on Distribution
When interruptions (such as port congestions or weather) occur, a more nimble supply chain may optimize and reroute shipments, immediately sharing these changes throughout the supply chain and informing direct consumers. Businesses may save costs and boost on-time delivery with the use of smarter network stocking at distribution centers (such as bundling shipments). This can be accomplished via better sorting and visual inspection.
Impact on Call Centers
Maximizing assistance for suppliers, customers, wholesalers, and sales teams is made possible by data science and AI thanks to the increased accuracy and efficiency of tools like chatbots and voice-activated assistants (e.g., expected delivery times).
The prevention of warranty and procurement fraud will also be aided by AI, blockchain, and data integration developments. Smart contracts will speed up the resolution of legal disputes and boost the enforcement of agreements.
Impact on Sourcing/Procurement
By virtue of its data-intensive nature, cognitive sourcing or procurement will facilitate enhanced supplier selection and permit more frequent opportunity reevaluation. As a result of increased augmentation and automation in this sector, product development cycles may move at a faster pace, prices can be reduced, product quality can be improved, and connections with suppliers can be strengthened.
Impact on Pricing
With dynamic pricing, businesses may better respond to consumer demand, capitalize on emerging opportunities, and expand their market share. In addition, businesses will be able to manage demand in line with the current capabilities of the supply chain and the most lucrative revenue opportunities.
One of the most promising developments in predictive analytics occurs when digital strategies develop via unified data and powerful platforms.
With the use of customer data and AI, Home Depot has been working to improve the digital shopping experience for its customers and iron out any kinks in the supply chain. Chris Smith, a spokesperson for Home Depot, gave the example of an item page for a temporarily out-of-stock appliance or equipment, which displays nearby store locations and similar products for sale. It is an incredible supply chain forecasting tool, and also a crucial component of forecasting in the supply chain.
With automation, from their distribution centers to their forecasting and replenishment systems, Home Depot will continue to look for places where they can optimize and automate to make better decisions. Machine learning is used in a variety of ways to help Home Depot make better, faster decisions, such as in how they support the movement of inventory through their supply chain and how they understand available capacity to support their customers.
For Paack, foresight might come in the shape of impending traffic, storms, or the possibility that a returning client will be accessible or not.
Data and analytics play a crucial role in Seara, not only for the health of the company but of the whole planet. Anticipating problems might be the difference between saving a crop and losing it as climate change, supply chain disruptions, global conflicts, and migration continue to put pressure on food production.
Seara has begun developing artificial intelligence (AI) tools for advanced analytics, with the goal of not only alerting users to issues in real time but also making predictions about the near and far future.
From the factory to the warehouse to the shop and now to the front door, businesses have always been interested in maintaining visibility at every stage of the production process. The increase in the quantity of data and, along with it, our capacity to analyze it has led to an increase in the complexity of the situations, which presents both a difficulty and a need for doing so. Due to the fact that it is on a scale that no human being can possibly handle, not just data but also analytics and artificial intelligence are becoming more important.
Home Depot has been able to see these expanding interdependencies from a front-row seat, particularly when it comes to the provision of services to customers that are complementary but competitive.
The pandemic presented its share of unexpected opportunities, as the combination of rising home values, disposable income, and do-it-yourselfers looking for (stay at) home projects led to runs on everything from lumber to sheds-turned-offices to garage doors. This resulted in a significant increase in the demand for these products. Customers may get irate if there are empty shelves at the store. According to Chris Smith, vice president of IT Supply Chain at Home Depot, the company was competing not just with homeowners and renters in this instance, but also with a base consisting of contractors and even large-scale developers, which is becoming an increasingly relevant demographic. Each one has its own unique requirements, which might occasionally be in conflict with one another.
Home Depot really makes use of something that is known as an omnichannel algorithm. It is really about matching the preferences of the customer with our understanding of capacity, assortment, and inventory availability. After putting all of that information together, the question that needs to be asked is: How can they best meet the customer promise while also making the most efficient use of their supply chain? So where do they fulfill it from, where is the inventory accessible, and how can we accomplish it in a manner that is most cost-effective for us while still keeping the promise we made to the customer? Those are the questions we need to answer.
Similarly, Paack, a start-up that provides last-mile delivery and serves the United Kingdom, Spain, France, Portugal, and Italy, is pushing the edge regarding fulfillment. To assure guaranteed delivery, the firm focuses on merging a vast amount of data, which comes from drivers, consumers, sensors, the weather, and other sources. Their success record for on-time delivery is close to 98%, and they use unique scheduling technologies to make sure that their clients are ready to accept their items when they are delivered.
Paack is able to manage its drivers and clients in real time thanks to technological advancements such as the Last Mile Fleet Solution from Google Maps Platform.
The granularity of the information that they are able to collect, in terms of which routes are actually being followed by the driver's route as opposed to the routes that were planned, the ability for them to change directions, because we might know locally of better ways to go, and notifications from the customer as to their availability are all things that really allow us to build a better experience for everyone. They want first-time drivers to be the most productive drivers, and this initial step gives them the opportunity to achieve that goal.
The success of Paack demonstrates the value of creating a robust platform for consumers and employees and using other platforms, such as Google Maps, to boost your own.
Overseas, the biggest beef supplier in the world is working to give thousands of farmers and ranchers their own voice. Brazilian meat, poultry, and egg distributor Seara, a subsidiary of the multinational JBS corporation, introduced its SuperAgroTech platform in July 2021.2
Despite being in the works for quite some time, the program's launch couldn't have come at a more crucial moment for the world's food supply. After already dealing with shutdowns and shortages caused by the epidemic, the food sector was hit with further fallout from the conflict in Ukraine.
The whole supply chain was impacted, and adjustments had to be made to the organization as a whole. Since the same problems crop up time and time again in the fields and farms, the development of this online digital platform may be seen as a facilitator since it gives the farmer more freedom by making data entry and digital communication more accessible to them. The farmers and Seara have a degree of interaction that has never existed before.
More than 9,000 farms across the world are already using the technology. Teams may monitor a variety of outcomes with the use of Internet of Things (IoT) sensors, monitoring devices, and data inputs from farmers, operators, and Seara data. A growing number of customers place a premium on factors including crop yields, livestock health, financial returns, and social and environmental implications.
Complete digitalization of agricultural operations is a long-term aim.
As a result, they can now activate any producer in a matter of seconds, no matter where it is. Where in the nation the SuperAgroTech platform is located makes no difference to the system. In addition to fostering deeper connections, this approach encourages more individualized care for our farmers.
Developing effective supply chains is possible via the application of methodologies for managing supplier relationships that use big data and machine intelligence. Even though big data analytics is not commonly used in supply chain firms, the future of managing supplier relationships will heavily rely on big data analytics and machine learning. Companies participating in the supply chain must have access to reliable data on their suppliers to develop effective relationship management strategies. The vast bulk of qualitative information is what people want. This procedure is comprised of audits, assessments, and evaluations.
With the support of big data analytics in supply chain management, these companies may collect and assess the aforementioned data. As a result, businesses will be able to track the activities and information of their providers throughout time, for both current and future usage. In addition, they will be able to conduct activities related to intelligent and predictive supplier selection. Because of this effort, the procurement process will be more transparent and there will be more prospects for long-term partnerships. In addition, supply chains will have access to up-to-date information that anyone may evaluate and use. In addition, customers will have access to a variety of indications for determining which service provider best meets their needs and preferences.
Big data analytics is useful in the area of smart manufacturing for identifying solutions to the organization's difficulties at the required rate. Big data analytics is a useful tool for manufacturers, aiding in the formulation of plans, the exchange of data, the development of predictive models, and the management of factory operations through interconnection. This may be achieved via the use of big data analytics. Utilizing big data analytics in supply chain management offers several benefits, including the routing of order pickup and delivery, and the assignment of orders to suitable agents.
In addition, designers want tools that can anticipate and evaluate the changing preferences and expectations of consumers throughout the product's life cycle. Collecting, managing, and using innovative analytic techniques to get actionable insights and data, and then applying this knowledge to decision-making, may help lessen the amount of uncertainty that occurs.
If orders are delivered in an incomplete or incorrect condition, a company's image might suffer. In today's "age of the customer," it is crucial to give the proper thing to the right person at the right time and place to maintain customer happiness and loyalty. By analyzing vast quantities of consumer data, astute businesses may get a holistic perspective of their clientele from every viewpoint. As a result, businesses are better equipped to anticipate client demands, understand their preferences, and provide a unique brand experience.
Using predictive analytics, you may evaluate the chance of an issue arising as well as its possible effects. Predictive analytics in Big Data may be used to aid in the detection of possible Supply Chain risks by evaluating vast quantities of historical data and using a variety of risk mapping methodologies. In addition, precise risk estimates may aid in the creation of equipment and procedures that mitigate the effects of potential threats.
Logistics management is another area where big data analytics may be used to great effect in supply chain administration. Finding strategies to optimize service experiences, such as delivery speed, resource application, and geographic coverage, is one of the most persistent issues when it comes to logistics systems. It would be expensive for logistics companies to make either late or early deliveries. The time that elapses between the projected delivery and the actual delivery is one of the leading causes of concern for logistics organizations. The use of big data analytics in the management of supply chains may reduce the likelihood of delivering erroneous delivery time estimates. This may help you improve traceability, which guarantees that products can be monitored from the moment of manufacturing to the point of sale.
This enhanced tracking system has the ability to facilitate the integration of various supply chain organizations and the ongoing flow of items. Large warehouses, for instance, might reorganize pallets automatically throughout the night in order to enhance the next day's schedule with the use of big data analytics. In addition, firms are able to assess the efficiency of pickers in various picking zones in order to optimize future employment.
The maintenance sector is progressively using big data, and as a consequence, the maintenance team is becoming more efficient. The use of data analytics is improving the effectiveness of the maintenance department, which is resulting in an increase in the amount of uninterrupted time for operations. By merging data from its machines with data from other areas, the organization is able to more precisely evaluate the health and performance of its equipment. Installation of sensors and subsequent data analysis are the key approaches for achieving this objective. Using data acquired in real time and a built model, an operator may forecast when a machine would break down by analyzing real-time data. The use of data analytics results in more than the replacement of components before they become damaged. Utilizing more sophisticated data may aid in acquiring a greater understanding of the several techniques available for extending the usable life of an existing asset.
Companies operating throughout the supply chain are already using diverse data analytics. The majority of contemporary analytics are descriptive. Descriptive analytics is a collection of methods to summarize data and identify patterns. This form of analysis does not foretell the future; rather, it recounts previous events based on historical facts, numbers, statistics, etc. The purpose of diagnostic analytics is to provide insight into why something occurred.
Every analytical procedure starts with data collecting. Data might originate from a variety of sources, including sales and purchase forms, invoices, delivery notes, CMRs, and customs papers, among others. Complex supply networks generate a large amount of data. The difficulty is in processing this data and using business intelligence analytics to comprehend what occurred, why it occurred, and make the best business choices for the future.
Predictive analytics goes a step further with data by addressing questions about the future, such as what will occur. For predictive analysis purposes, information must be translated into a form that is more usable. Typically, this step is not taken until after descriptive analytics solutions have been installed, since many businesses are unaware of the wealth of information in their historical data sets.
With prescriptive analytics, the most effective and remarkable data science analytics include acquiring foresight and an intelligent action plan. Prescriptive analytics is predictive analytics with a goal; it involves creating prediction models and using them to decide the optimal course of action for future occurrences. Learn all of the above in KnowledgeHut’s Bootcamp for Data Science.
The use of data science in logistics may assist firms in better optimizing operations. This involves everything from determining which delivery routes to use to better managing fuel (and when to go) and more precise forecasting of supply and demand.
