Planning and Optimisation to Facilitate Disassembly in a Recycling Oriented Manufacturing System
Product recycling and planning for it is becoming increasingly important to industry as they face the future threat of product takeback legislation. This paper presents a methodology which is concerned with achieving an optimum disassembly plan for a product when it reaches the end of its useful life. The methodology illustrates ways in which optimisation can be achieved through establishing certain criteria at the design stage ensuring that the product has a favourable disassembly plan. A favourable plan is one which when optimised results in positive recycling profit making the product attractive to recyclers and so minimising the amount of material which must be sent to landfill. The methodology ensures that a product which can easily be disassembled into its constituent parts gains a favourable score whilst products which cannot easily be disassembled are penalised. The methodology presented can be applied to a product in a number of ways, these are discussed.
