Next class • Vestel case • Read the case before class • Please e-mail presentation slides before class
Relating to practice • Efes: solved transportation problem using LP • Vestel: Will see application involving other transportation related issues we will talk about today: vehicle selection, routing
Data for routing • Mileage Estimation • Street Network • Straight line distances • This is of course an underestimate of the road distance. To estimate the road distance we multiply the straight line distance by a scale factor, . Typically =1.3.
Vehicle Routing • The fleet : • types • sizes • costs • Customer : • location • demand • accessibility Delivery zone
Vehicle routing problem Given the demand at i clients determine the itineraries of K vehicles with a given capacity Q
VRP : heuristic approach • Savings algorithm (Clarke and Wright 1964) • Initial phase : • create n routes (0,i,0), where 0 is the transit point (or DC or depot) • calculate the savings sij = ci0 + c0j - cij and order them in decreasing order • Go over the savings list trying to combine the routes : • Find a route that terminates with i and another that starts with j • Verify capacity constraints Initial solution : Combine :

Objectives of a strategic alliance • Adding value to products: improving time to market, distribution times, etc. • Improving market access: better advertising, more channels, etc. • Strengthening operations: lowering system costs, cycle times, etc. • Adding technological strength • Enhancing strategic growth: overcoming entry barriers • Enhancing organizational skills: learning, self-learning • Building financial strength: risk sharing, increasing income, etc.
SPs in SCs • 3PL • Retailer-supplier partnerships • Quick response • Continuous replenishment • Advanced continous replenishment • VMI • Distributor integration • Transshipment • Technical expertise sharing
Example: 3PL • Focus on core strengths • Provides technological flexibility • Provides other flexibilities: geographic locations, regional warehousing, etc. • Disadvantages: loss of control, 3PL interacting with customers • A form of outsourcing
3PL Success factors • Know your own costs • Measurability-data availability • Activity based costing • Customer orientation of the 3PL • Specialization of the 3PL • import-export • Small package • Warehousing • Ship logistics • Etc. • Asset-owning versus non-asset-owning
3PL Implementation Issues • Effective communication • Performance measures • Detailed contracts/agreements • Performance follow-up procedures
Distributor integration: transshipment • “shipment of items between different facilities at the same level in the supply chain to meet some immediate need” • Between retailers • Between separately owned distributors: requires distributor integration, typically orchestrated by the manufacturer • Information system to enable inventory visibility • Incentives both ways so that distributors are willing to share their inventory
