Abstract
The objective of this research is to propose an optimization method in order to balance work loads for engineers joining in multiple projects. Every project is planned carefully to give appropriate work load to all engineers who join in the project and execute tasks. Though, since every engineer can join in the multiple projects, as a result, some engineers may be forced excessive work load to achieve the scheduled project plan. Therefore the project manager has to modify the project plan according to the necessities. There are feasible solutions to release the engineers from the excessive work load. In this paper, we propose a method for extending the operating term. The operating term is provided to execute the substance process of the task, which in general has longer time than the processing time. Since the processing time is fixed, the extension of the operating term causes the reduction of the work load.
