    • FACULTY OF COMPUTER SCIENCE AND MATHEMATICS INTRODUCTION TO E-BUSINESS (ITS450) SUPPLY CHAIN Sharifah Syahirah bt Syed Muhd Kamal Nur Hakma bt Juhari Nur Farahain bt Supian (2009249956) (2009600066) (2009627474)
    • Definition
      • A system of organizations, people, technology, activities, information and resources involved in moving a product or service from supplier to customer.
      CHRISTOPHER [1998]
      • A network of connected and interdependent organizations mutually and co-operatively working together to control, manage and improve the flow of material and information from suppliers to end users.
      JOHANSSON [2002]
      • A system whose constituent parts include material suppliers, production facilities, distribution services and customer linked together via the feedforward flow of materials and the feedback flow of information
    • Part Of Supply Chain
      • Supply focuses on the raw materials supplied to manufacturing, including how, when, and from what location.
      • Manufacturing focuses on converting these raw materials into finished products.
      • Distribution focuses on ensuring these products reach the consumers through an organized network of distributors, warehouses, and retailers
    • Supply chain decision
    • Location decision
      • production facilities, stocking points, and sourcing points is the natural first step in creating a supply chain.
      • The location of facilities involves a commitment of resources to a long-term plan
      • great significance to a firm since they represent the basic strategy for accessing customer markets, and will have a considerable impact on revenue, cost, and level of service.
    • Production decision
      • products to produce, and which plants to produce them in, allocation of suppliers to plants.
      • Operational decisions focus on detailed production scheduling.
      • - include the construction of the master production schedules, scheduling production on machines, and equipment maintenance.
    • Inventory decision
      • inventories are managed and exist at every stage of the supply chain as either raw materials, semi-finished or finished goods.
      • primary purpose to buffer against any uncertainty that might exist in the supply chain.
      • include deployment strategies (push versus pull), control policies --- the determination of the optimal levels of order quantities and reorder points, and setting safety stock levels, at each stocking location.
    • Transportation decision
      • closely linked to the inventory decisions, since the best choice of mode is often found by trading-off the cost of using the particular mode of transport with the indirect cost of inventory associated with that mode.
      • customer service levels, and geographic location play vital roles in such decisions.
      • Shipment sizes (consolidated bulk shipments versus Lot-for-Lot), routing and scheduling of equipment are key in effective management of the firm's transport strategy.
    • Supply Chain Flow
      • 3 main flow:
        • information flow
        • material flow
        • cash flow
      • information flow : interaction between customer and supplier
      • material flow: deliver the material to the end-user via procurement of raw materials, manufacturing, distribution and customer service.
      • cash flow: customer pay the material cost.
    • Supply Chain Flow
    • Supply Chain Dynamics and Risk
      • Supply chain do not always behave as expected
      • Excessive demand variability – due to information distortion in supply chain
      • Distortion known as Bullwhip of Forrester effect
      • Result of uncertainties is the supply chain risk.
    • Supply Chain Dynamics and Risk
