Disassembly matrix for liquid crystal displays televisions

摘要

Waste Electrical and Electronic Equipment (WEEE) are one of the most significant waste products in modern societies. Disassembly is a critical step to reduce Electrical and Electronic Equipment (EEE) waste. In the past two decades, despite disassembly has been applied to support recycling and remanufacturing of WEEE products worldwide, full disassembly of WEEE is rarely an ideal solution due to high disassembly cost. Disassembly planning and sequencing has therefore become an important but still a challenging research topic in recent years. In this paper, based on product model, space interference matrix can be generated to represent the space interference relationship between each component of product, and all feasible disassembly sequences can be obtained by analysing the space interference matrix in six directions in a 3D environment. The obtained feasible disassembly sequences can be used as solutions to support our developed Particle Swarm Optimisation (PSO)-based selective disassembly planning method to search optimised selective disassembly sequence for Liquid Crystal Display (LCD) televisions.
