Abstract
Product recovery strategy requires a thoughtful consideration of environmental implications of operational processes, undergone by a manufactured product in its entire product lifecycle, from stages of material processing, manufacturing, assembly, transportation, product use, product post-use and end-of-life. At the returns stream from product use stage, those parts and/or component assemblies from a used product have several disposition alternatives for recovery, such as direct reuse, remanufacture, recycle or disposal. Due to such complexity of the manufacturing processes in recovery, current decision methodologies focus on the performance measures of cost, time, waste and quality separately. In this article, an integrated decision model for used product returns stream is developed to measure the recovery of utilisation value in the aspects of cost, waste, time, and quality collectively. In addition, we proposed a model-driven decision support system (DSS) that may be useful for manufacturers in making recovery disposition alternatives. A case application was demonstrated with the use of model-driven DSS to measure recovery utilisation value for the used product disposition alternatives. Finally, the future work and contributions of this study are discussed.
Highlights
Manufacturers are currently facing significant challenges on minimising used product disposal rate and landfill burdens within the returns stream [1,2,3]
There are worldwide environmental authorities, such as governmental bodies and agencies, suppliers, manufacturers, distributors, retailers etc., that have emphasised on the development of sustainable manufacturing along a supply chain, total waste minimisation over its product lifecycle is still not easy to achieve at a satisfactory level [4,5,6,7,8]
This study focused on the proposed recovery options of “RA” and “RB” to see the difference of overall performance evaluation of RUVREC
Summary
Manufacturers are currently facing significant challenges on minimising used product disposal rate and landfill burdens within the returns stream [1,2,3]. The operations strategy to deal with those parts and/or components from used product to be reused, remanufactured and recycled in the manufacturing process is important. One of the primary reasons is that there are dispositions alternatives for achieving increased used product utilisation upon returns [5,6,9,10,11,12,13,14,15,16]. It commonly refers to the product redesign plan for returns stream in the manufacturing industries, by increasing
