Minimizing total earliness/tardiness penalties for common due date with general job-dependent learning effect

28128

In the literature, Earliness/Tardiness (E/T) problem was known as weighted absolute deviation problem. Both tardiness and earliness are very important performance criteria for scheduling problems. While total tardiness criterion provides adaptation for due date (ignoring results of early performed jobs), it deals with only cost of tardiness. However this phenomenon has been started to change with Just in Time (JIT) production concept. On JIT production, earliness is as important as tardiness. The phenomenon of the learning effect has been extensively studied in many different areas of operational research. However, there have been a few studies in the general context of production scheduling such as flow-shop scheduling. In this paper, we considered the minimization of the total earliness/tardiness penalties from a common due date under general job-dependent learning effects problem on a two-machine flow-shop scheduling environment. Furthermore, an interface at the Microsoft Excel was projected with Decision Support System Approach for Small and Medium Size Enterprises (SME). This interface could be easily used by SMEs, which have similar scheduling problems. This interface can also be improved/transformed for SMEs’ different scheduling problems.
