Abstract
This paper addresses the problem of creating intelligent, green, and financially-beneficial disassembly sequences for end-of-life (EOL) electronic products. These complex EOL products contain a broad spectrum of materials including precious metals. Therefore, one would have to process these products to retrieve the value buried in them. EOL processing options include, reuse, remanufacturing, recycling or proper disposal. Each of this option requires a certain level of disassembly. Hence, obtaining an optimal or near optimal disassembly sequence is crucial to increasing the efficiency of EOL processing. Since the complexity of determining the best disassembly sequence increases as the number of parts in a product grows, an efficient methodology is required for disassembly sequencing. In this paper, we present an evolutionary algorithm for generating near-optimal and/or optimal sequences for selective disassembly of EOL products. A numerical example is provided to demonstrate the functionality of the algorithm.

After the data is embedded in the genetic algorithm (GA), the user is prompted for the type of disassembly operation
Summary
Advanced technology products are regularly rendered technically obsolete within a few years of commercialization due to the rapid pace of technological enhancement. For example, electronic products are frequently discarded before their materials degrade. These complex end-of-life (EOL) products contain a broad spectrum of materials including precious metals such as silver and gold and valuable materials such as copper. The economically and environmentally sustainable option is to reuse these components in technically valid products. EOL processing options such as reuse, recycle and remanufacturing are effective ways to reclaim the materials and the components in electronic EOL products [5, 8]. Is the process of the systematic removal of desirable constituents (components and/or materials) from the original assembly so that there is no impairment to any useful constituent. Recent books by Lambert and Gupta [13] and McGovern and Gupta [17] can be helpful in understanding the general area of disassembly
