Comparison of Five Alternative Manufacturing Strategies For increasing Job Shop Capacity and Their Impact on Manufacturing Performance

Managing job shop manufacturing is quite different compared to other manufacturing systems due to its dynamic changes in process routings, cycle times and fluctuations in demand. Managers in job shops face problems in attaining optimum performance of the job shops. These can lead to failure to meet...
