In this chapter, the following content will be discussed: Introduction, definitions, the Rs of reverse logistics (RL), RL scope, reasons for RL (Operational & Strategic), evolution of RL in organisations, process for RL management, comparison of forward logistics Vs RL, advantages of RL, RL cases that enhanced competitive Adv, conclusion. | 1-1 Logistics Management LSM 730 Dr. Khurrum S. Mughal Lecture 15 1 Cost-Profit-Volume Analysis Cost-Profit-Volume Analysis Cost-Profit-Volume Analysis Since Bowling Green has the lowest Total Cost at the volume being produced, it will be chosen as the site of new facility 4 13-5 CR (2004) Prentice Hall, Inc. A more complex problem that most firms have. It involves trading off the following costs: - Transportation inbound to and outbound from the facilities - Storage and handling costs - Inventory carrying costs - Production/purchase costs - Facility fixed costs Subject to: - Customer service constraints - Facility capacity restrictions Mathematical methods are popular for this type of problem that: - Search for the best combination of facilities to minimize costs - Do so within a reasonable computational time - Do not require enormous amounts of data for the analysis Multiple Location Methods 13-6 Location Cost Trade-Offs (Heuristic) Number of warehouses Cost Production/purchase and order processing Inventory carrying and warehousing Warehouse fixed Inbound and outbound transportation Total cost 0 0 CR (2004) Prentice Hall, Inc. 13-7 CR (2004) Prentice Hall, Inc. Location of truck maintenance terminals Location of public facilities such as offices, and police and fire stations Location of medical facilities Location of most any facility where transportation cost (rather than inventory carrying cost and facility fixed cost) is the driving factor in location As a suggestor of sites for further evaluation Examples of Practical COG Model Use 13-8 CR (2004) Prentice Hall, Inc. A method used commercially - Has good problem scope - Can be implemented on a PC - Running times may be long and memory requirements substantial - Handles fixed costs well - Nonlinear inventory costs are not well handled Mixed Integer Programming 6-9 Transport Fundamentals CR (2004) Prentice Hall, Inc.
