Title: Logistics and Supply Chain Management

Logistics and Supply ChainManagement
2
Logistics
  • The process of planning, implementing, and
    controlling the efficient, cost-effective flow
    and storage of goods, services, and related
    information, from point of origin to point of
    consumption, for the purpose of conforming to
    customer requirements.
  • Components of an Integrated Logistics System
  • Physical Supply links suppliers to operations
    process
  • Internal Operations manages in-process material
    flow
  • Physical Distribution links operations process
    to customers

Supply Chain Management
  • A philosophy that describes how organizations
    should manage their supply chains to achieve
    strategic advantage
  • The objective is to synchronize requirements of
    the final customer with the flow of materials and
    information along the supply chain. The goal is
    to eliminate variability and reach a balance
    between high customer service and low cost

5
SCM the need to reduce variability or the impact
of variability on the supply chain
  • Supply network variability
  • late deliveries weather,equipment breakdown
  • quality problems
  • Manufacturing process variability
  • machine reliability and equipment failure
  • changeovers / setups / part expediting
  • design and quality problems
  • Customer network variability
  • cancellations and irregular orders
  • equipment failure
  • scheduling

Carrying safety inventories are the most common
approach to dealing with variability
6
Information Technology in SCM
  • Seen as the key to variability reduction
  • Links the success of independent suppliers,
    manufacturers, and customers
  • Risks and rewards are shared among supply chain
    partners
  • Many technologies are accepted among supply chain
    managers
  • Electronic data interchange (EDI)
  • Artificial intelligence / Expert systems
  • Bar code and radio frequency systems
  • Internet applications

7
Environmental Sensitivity
  • NOW Supply chains create tremendous amounts of
    waste material to protect goods in shipment and
    storage.
  • FUTURE Distribution will use reverse logistics,
    the recycling or proper disposal of cardboard,
    packing material, strapping, shrink wrap,
    pallets, etc...

Bullwhip Effect
The magnification of variability in orders in the
supply-chain.
Retailers Orders

A lot of retailers each with little variability
in their orders.
can lead to greater variability for a fewer
number of wholesalers, and
can lead to even greater variability for a
single manufacturer.
