ABSTRACT

The scheduling with due-date assignment problem has been a prevalent topic in recent decades. Traditionally, scheduling and due-date assignment were done separately, and most of the time, due dates were determined externally. Considering the two functions separately would have adverse effects on the global solution. The due dates given independently of the shop floor would not comply with the shop floor conditions, and they would be either too early or too long due dates. Therefore, integrating the two functions and their concurrent solution was very important. Since the due dates given internally consider the shop floor conditions and the customer, they became more reasonable. Again, while only tardiness was punished classically, with the spread of just-in-time philosophy, earliness and due dates were also punished. In many studies, objective functions such as makespan, average tardiness, maximum tardiness, total tardiness, and the number of tardy jobs are also used.
