Abstract
Machine idle time is one of the main causes for lower machine utilization and prevents the use of its full potential and capacity. As a result, the value of average flow time and makespan increases and becomes a reason for production and delivery delays. Since the last few decades, a number of scheduling and sequencing techniques have been developed by many researchers to minimize these causes. Among them, most techniques are concerned with decreasing average flow time and makespan value. In this paper also, a new heuristic technique is developed for decreasing such causes. The results are compared with that obtained by using some standard dispatching rules and found that the developed heuristic algorithm is performing better in minimizing the values of makespan, average flow time and number of machine set ups required.
