Optimal analysis of lot-size balancing for multiproducts selective disassembly

摘要

In recent years, there has been an appalling depletion of natural resources resulting from the ever-increasing number of consumer manufactured goods that, in turn, has led to an increased quantity of discarded, used, and outdated products. From an environmental viewpoint, not only is it desirable to disassemble, reuse, or recycle components and materials from discarded products; in many cases it is also economically justifiable. This paper presents a quantitative methodology for product disassembly and recycling by considering both operational and environmental factors. Therefore, we present a mathematical programming model that provides a unique solution for planning component recovery from products with component commonality. The objective of thecomponent recovery model is to compute the number of products to disassemble to fulfill the demand of the components, at minimal disassembly and disposal costs. A case study illustrates the method.
