E-business Opportunities: • Reduce Facility Costs • Eliminate retail/distributor sites • Reduce Inventory Costs • Apply the risk-pooling concept • Centralized stocking • Postponement of product differentiation • Use Dynamic Pricing Strategies to Improve Supply Chain Performance
E-business Opportunities: • Supply Chain Visibility • Reduction in the Bullwhip Effect • Reduction in Inventory • Improved service level • Better utilization of Resources • Improve supply chain performance • Provide key performance measures • Identify and alert when violations occur • Allow planning based on global supply chain data
Logistics Design Decisions • Determine the appropriate number of warehouses • Determine the location of each warehouse • Determine the size of each warehouse • Allocate space for products in each warehouse • Determine which products customers will receive from each warehouse
Logistics Design Decisions • Determine the appropriate number of warehouses • Determine the location of each warehouse • Determine the size of each warehouse • Allocate space for products in each warehouse • Determine which products customers will receive from each warehouse
Decision Classifications • Strategic Planning: Decisions that typically involve major capital investments and have a long term effect 1. Determination of the number, location and size of new plants, distribution centers and warehouses 2. Acquisition of new production equipment and the design of working centers within each plant 3. Design of transportation facilities, communications equipment, data processing means, etc.
Decision Classifications • Tactical Planning: Effective allocation of manufacturing and distribution resources over a period of several months 1. Work-force size 2. Inventory policies 3. Definition of the distribution channels 4. Selection of transportation and trans-shipment alternatives
Decision Classifications • Operational Control: Includes day-to-day operational decisions 1. The assignment of customer orders to individual machines 2. Dispatching, expediting and processing orders 3. Vehicle scheduling
Performance Measures • What you measure is what you get • Performance measures strongly affect the behavior of managers and employees • Tailor your performance measures to fit company’s mission and strategy • Over-reliance of a single measure might be detrimental to company’s long-term survivability

Critical Factors in SC Performance Metrics • Establish performance objectives with customers in mind • Consider using order windows as the basis for order fulfillment metrics • Reflect reliability issues in the metrics they choose • Implement metrics consistently throughout the supply chain • Aggregate results as they move up the chain
Critical Factors in SC Performance Metrics (cont’d) • Apply process control techniques to the business process • Avoid pitting players in the systems against one another • Collect only data you really intend to use • Communicate the actions and rational to everyone
Bullwhip Effect Increasing propagation of variability upstream through the supply chain
Increasing Variability Upstream the Supply Chain –Bullwhip Effect
What are the Causes…. • Demand forecasting • Min-max inventory level • Order-up-to level • orders increase more than forecasts • Long cycle times • Long lead times magnify this effect • Impact on safety stock • Product life cycle • Batch ordering • Volume & transportation discount
What are the Causes…. • Price fluctuation • Promotional sales • Forward buying • Inflated orders • Orders placed increase during shortage periods • IBM Aptiva orders increased by 2-3 times when retailers thought that IBM would be out of stock over Christmas
Ways to Cope with the Bullwhip Effect • Reducing uncertainty • Centralizing demand information • Bullwhip inherent in use of various forecasting techniques • Reducing variability • Use of EDLP strategy (Payless)
Ways to Cope with the Bullwhip Effect (cont’d) • Lead time reduction • Order lead time (time to produce and ship) • Information lead time (time to process order) • Efficient network distribution design • Strategic partnership • Vendor managed inventory (VMI) • Sharing of customer information • Collaborative forecasting
