  • Dell has three production sites worldwide and builds to order. Compaq does both. Consider some decisions involved - where to locate facilities? How to size them? Where is the push/pull boundary? What modes of transport to use? How much inventory to carry? In what form? Where to source from?
  • FMCG
  • What is shown here is how divergent these various forecasts are in relation to real demand. Why?? Because they are developed independently from each other and are dated, and unconnected to each other and the daily fluctuations in the market

    13. 13. Some Definitions <ul><li>Supply Chain Management encompasses every effort involved in producing and delivering a final product or service, from the supplier’s supplier to the customer’s customer. Supply Chain Management includes managing supply and demand, sourcing raw materials and parts, manufacturing and assembly, warehousing and inventory tracking, order entry and order management, distribution across all channels, and delivery to the customer. </li></ul><ul><li> The Supply Chain Council, U.S.A. </li></ul>Management Information System

    17. 17. Supply chain objective <ul><li>Maximize overall value generated </li></ul><ul><li>Value strongly correlated to supply chain profitability – the difference between the revenue generated from the customer and the overall cost across the supply chain </li></ul><ul><li>Example : A customer purchasing a computer from Dell pays $ 700 (the revenue) </li></ul><ul><li>Dell and other stages of the supply chain incur cost to convey information, produce the components, store them, transport them, transfer funds, etc. </li></ul>Management Information System
    18. 18. Why is SCM Important? <ul><li>Strategic Advantage – It Can Drive Strategy </li></ul><ul><li>* Manufacturing is becoming more efficient </li></ul><ul><li>* SCM offers opportunity for differentiation (Dell) or cost reduction (Wal-Mart or Big Bazaar) </li></ul><ul><li>Globalization – It Covers The World </li></ul><ul><li>* Requires greater coordination of production and distribution </li></ul><ul><li>* Increased risk of supply chain interruption </li></ul><ul><li>* Increases need for robust and flexible supply chains </li></ul>Management Information System
    19. 19. Why is SCM Important? (continued) <ul><li>At the company level, supply chain management impacts </li></ul><ul><li>* COST – For many products, 20% to 40% of total product costs are controllable logistics costs. </li></ul><ul><li>* SERVICE – For many products, performance factors such as inventory availability and speed of delivery are critical to customer satisfaction. </li></ul>Management Information System

    25. 25. Management Information System What is Supply Chain Planning ? Supply Chain is a set of activities (e.g. purchasing, manufacturing, logistics, distribution, marketing) that perform the function of delivering value to end customer Traditionally, all the business units along a supply chain have their own objectives and these are often conflicting There is no single plan to carry out supply chain activities
    26. 26. Management Information System What is Supply Chain Planning ? There is need for a mechanism through which the execution of various business activities along a supply chain can be planned in an integrated fashion. The supply chain planning is an effort to achieve the primary goal of “ producing and distributing the merchandise at the right quantity, to the right locations, and at the right time with minimum system wide cost ” in the presence of conflicting goals of various business units

    30. 30. Uncertainty in Supply Chain <ul><li>Wrong Forecasts </li></ul><ul><li>Late Deliveries </li></ul><ul><li>Poor Quality </li></ul><ul><li>Machine Breakdowns </li></ul><ul><li>Canceled Orders </li></ul><ul><li>Erroneous information </li></ul>Management Information System
    31. 31. Managing Uncertainty <ul><li>Point forecasts are invariably wrong </li></ul><ul><li>↓ </li></ul><ul><li>Plan for forecast range – use flexible contracts to go up/down. </li></ul><ul><li>2. Aggregate forecasts are more accurate </li></ul><ul><li> ↓ </li></ul><ul><li>Aggregate the forecast – postponement/risk pooling </li></ul>
    32. 32. Managing Uncertainty (cont’d) <ul><li>Longer term forecasts are less accurate </li></ul><ul><li> ↓ </li></ul><ul><li>Shorten forecasting horizons – multiple orders; early detection </li></ul><ul><li>In many cases, somebody else knows what is going to happen </li></ul><ul><li>↓ </li></ul><ul><li>Collaborate </li></ul>
    33. 33. Complexities Involved in Supply Chain Management <ul><li>The supply chain is a complex network of facilities and organizations with different, conflicting objectives </li></ul><ul><li>Matching supply and demand is a major challenge </li></ul><ul><li>System variations over time are also an important consideration </li></ul><ul><li>Many supply chain problems are new and there is no clear understanding of all the issues involved </li></ul>

    40. 40. Modeling for SCM <ul><li>Forecasting Models </li></ul><ul><li>- These models allow prediction of demand based on past data or other parameters that are independently available. They enable better planning, given the lead-time necessary for response. </li></ul><ul><li>Location Models </li></ul><ul><li>- These models identify the optimal location of facilities such as plants and warehouses, considering the inbound and outbound transportation costs as well as the fixed and variable costs of operation at the locations under consideration. These are usually formulated as Mixed Integer Programming Models. </li></ul>Management Information System
    41. 41. Modeling for SCM (cont’d) <ul><li>Distribution Network Design Models </li></ul><ul><li>- These models are usually comprehensive in nature, deciding between two, three and even four stages of distribution network, location of warehouses and break-bulk points, and sometimes even the transportation. </li></ul><ul><li>Allocation Models </li></ul><ul><li>- These models help in optimally allocating commodities from sources to destinations in a multi-source, multi-destination environment. The costs considered for optimisation are production costs and warehousing costs. The constraints considered can be due to demand, capacity, route restrictions, etc. </li></ul>Management Information System
    42. 42. Modeling for SCM (cont’d) <ul><li>Inventory Models </li></ul><ul><li>- Inventory plays a major role in SCM. </li></ul><ul><li>- Inventory can be of various types such as: </li></ul><ul><li>- Batching and shipment inventories </li></ul><ul><li>- Buffer stocks to take care of uncertainties </li></ul><ul><li>- Pipeline inventory ( primary and secondary transportation ) </li></ul><ul><li>These models minimize the total relevant cost, based on trade-offs among, inter alia, inventory carrying cost, ordering cost, stock-out cost, transportation cost, taxes & duties, etc. </li></ul>Management Information System
    43. 43. Modeling for SCM (cont’d) <ul><li>Routing Models </li></ul><ul><li>- These models allow optimal routing on a transportation network from a given source to a destination. The models used are the Shortest Path Problem, the Traveling Salesman Problem and the Vehicle Routing Problem. Decision Support Systems that interactively use the expertise of the decision maker by providing graphical support through a map (i.e., using a Geographical Information System ) are also very useful in such decisions. </li></ul>Management Information System
    44. 44. Modeling for SCM (cont’d) <ul><li>Scheduling Models </li></ul><ul><li>- These models enable allocation of resources to particular activities. Depending on the criteria of interest and the number of resources, the models are of aid in evaluating appropriate rules for allocation. </li></ul><ul><li>Alternative Analysis </li></ul><ul><li>- This model simply proposes the identification of alternatives, criteria for decision making and analysis of the alternatives across the criteria to arrive at the best choice. Formal approaches such as simulation and analytic hierarchy process could be used in assessing the implications of the criteria. </li></ul>Management Information System
