Some new concepts of setup costs in multimode resource-constrained project scheduling problem

Abstract

The multimode resource-constrained project scheduling problem is considered. In some practical situations resources used to perform an activity have to be set up before the execution of this activity. Setup operations are characterized by two parameters setup time and setup cost. The latter is considered if the financial aspects of the schedule are taken into account. In this paper we present an adaptation of the classical models of setups, which are known from the machine scheduling theory, to the multimode project scheduling problem. Several new concepts are proposed as well.
