A Comparative Study of Existing Manufacturing, Planning and Control Approaches

During the 1980s various approaches to batch-type manufacturing environments were implemented. The most popular of these were Material Requirements Planning (MRP), Group Technology (GT) and Just-In-Time (JIT). However few successful implementations of any of these approaches were achieved [1] [2] [3]. This paper compares the various approaches of GT, MRP, JIT along with the integrated approaches such as MRP/GT and MRP/JIT.
