A Fuzzy AHP Approach for Calculating the Weights of Disassembly Line Balancing Criteria

Disassembly of outdated and previously consumed product takes place in field of remanufacturing, recycling, reusing and disposal. The disassembly lines have become the first choice for disassembly of the product that has been consumed previously. Disassembly line should be designed and balanced properly so that it can work as efficiently as possible. There are many different criteria in the disassembly lines for selecting the parts those are to be removed. The problem of disassembly line balancing is based on these different criteria. In this paper, the weights of these criteria have been evaluated. A fuzzy analytical hierarchy process (fuzzy AHP)-based approach has been applied to calculate the weight of each criterion. With the help of the weight of these criteria, the tasks can be assigned to workstations with different precedence constraint and cycle time limit.
