Expected Value Minimization Models of Project Scheduling Problem

Abstract

Project scheduling problem is to determine the schedule of allocating resources so as to balance the total cost and the completion time. This paper mainly introduce project scheduling problem with uncertain variables. In order to meet different management requirements, we put forward the number of workers constraint based on the activity duration times and total cost constraints. And activity duration times and the number of workers are assumed to be uncertain variables in this paper. Expected value model is an important tool for the solving of project scheduling problem. We established single-objective programming model and multi-objective programming model to meet different needs, respectively.
