Resource Constrained Disassembly Line Balancing Problem

Abstract

The disassembly line balancing (DLB) problem is the process of allocating a set of disassembly tasks to an ordered sequence of workstations in such a way that optimizes some performance measures (e.g., number of stations, hazardous components number, cycle time and work load). When disassembly operations are done on disassembly line, sometimes they need specific resources such as a robot, equipment, material, specific machine or qualified staff while working at the workstation. This issue also raises resource constrained disassembly line balancing (RCDLB) problem. Therefore, in this study, a mathematical model is presented for DLB problem by considering resource constraints. The objective is to minimize the number of resources and workstations under determined cycle time. The mathematical model is solved by using a mathematical programming package called as GAMS-CPLEX. Two examples from literature are solved and analyzed in order to test validity of the proposed model.
