Abstract:
Planning and scheduling are critical elements in optimizing the performance of aluminum extrusion plants. This study would focus on the significance of efficient planning and scheduling composite dispatching rules to ensure the timely production of high-quality aluminum profiles while minimizing energy consumption and material waste. Effective planning should involve accuracy forecasting demand, aligning production capacities, and determining optimal production sequences. Good scheduling would ensure that resources, including equipment and personnel, are allocated efficiently to maintain smooth production flows. Dispatching rules have known as popular, simple, and fast ways to find out the suitable, reasonably good alternatives. However, the bad solutions could be achieved with them especially with complex objectives. Apparent Tardiness Cost composite dispatching rule would be applied in this research to find out the better solutions with a case study in aluminum extrusion plant. A better sequence of jobs on the machines would be suggested, which could help reduce the penalty cost by reducing the total weighted tardiness of all the jobs at the machines as well as enhance ability to meet customers requirement on time by minimize makespans of all the jobs on the machines.
