Abstract:
The effect of cell locations and material transporters in the formation of manufacturing cells is investigated in this paper. Automated guided vehicles (AGVs) using a tandem configuration are considered and a first-come-first-served (FCFS) principle is applied for transporting the material between machines or between the input/output (I/O) and a machine. Using the time taken to perform material transfers as a suitable measure, a polynomial programming model is developed for the problem. As the model can be shown strongly NP-hard, a higher-level heuristic algorithm based upon a concept known as ‘tabu search’ is presented. An example problem is solved to further demonstrate that cell locations indeed have a significant impact when material transfers are used in the design of manufacturing cells.
