Chapter 5Distribution Strategies In Supply Chain Management
Introduction • Issues raised in the case (various alternative in distribution strategies) • Companies do not follow only one strategy and may combine different strategies based on different products • Eventually, various alternatives involves trade-offs.
Centralized versus Decentralized Control • Objective : Minimize the total cost across the entire chain (Ref. Barilla SPA) • Centralized system leads to global optimization (refer to Chapter 4) • Decentralized DS leads to local optimization • Also, a decentralized DS leads to more customization capability while centralized DS leads to more cost efficiency • Information is the heart of the difference
Three Basic DS Strategies • Direct shipment • Warehousing • Cross-docking Note that these strategies address B-to-B supply chain management
Direct Shipping • Advantages • Disadvantages • Common situations where direct shipping is desirable
Cross-Docking • Made famous by Wal-Mart • Little inventory at warehouse (usually less than 12 hours) • Difficult and expensive to start up • Key success factors • Linked information system • Fast are responsive transportation system • Accurate forecasts • Usually effective in large distribution systems (requires large volume)
Factors Affecting Choice of DS Strategy • Demand pattern (particularly volatility) • Location (market) • Service level • Costs • Comparison of DS Strategies: Table 5.1, page 115 • Flexibility/Variability Matrix
Transshipment • Definition • Requirements: • Advanced information system • Rapid shipping capability • What’s the impact of transshipping on risk-pooling? • Advantages of vertical integration in transshipping
Central versus Local Facilities • Safety stock • Overhead cost • Economies of scale • Lead time • Service level • Transportation costs
Push versus Pull Systems • TPS invented the “pull” system as a fundamental part of JIT system. • Differences in the two system
Push System • Production based on long-term forecast not the actual orders from the customers at the retail level. • Takes long time to react to changes in market • Creates “bullwhip effect” (with its related results, refer to Chapter 4)
Problems with Push Systems • Inability to meet changing market • Excessive inventory • Obsolescence of inventory • Large safety stock • Larger and more variable production batches • Long lead times
Pull Systems • Production is based on data from the final customer (POS data is critical) • Much more flexible system • Much more efficient system • JIT is a prime example of a pull system
Benefits of Pull Systems • Decreased lead times • Lower inventory costs • Decrease in variability in production • Better service • Less space • More flexible system
Pull versus Push • The two can be combined (combined with “postponement”) • Challenges of the Pull Systems • “Postponement Boundary”
