In this paper a novel modelling and solving method has been developed to address the so-called resource constrained project scheduling problem (RCPSP) where project tasks have multiple modes and also the preemption of activities are allowed. To solve this NP-hard problem, a new general optimization via simulation (OvS) approach has been developed which is the main contribution of the current re...

On the basis of uncertainty theory, plenty of researches have been done on uncertain resource-constrained project scheduling problems. Instead of minimizing the makespan, in this paper, we address the maximization of net present value of a project’s cash flows when activity durations are assumed to be uncertain. In addition to precedence constraint and resource constraint involved in resource-c...

This paper reports on a new solution approach for the well-known multi-mode resource-constrained project scheduling problem (MMRCPSP). This problem type aims at the selection of a single activity mode from a set of available modes in order to construct a precedence and a (renewable and non-renewable) resource feasible project schedule with a minimal makespan. The problem type is known to be NPh...

in this paper, a novel mathematical model for a preemption multi-mode multi-objective resource-constrained project scheduling problem with distinct due dates and positive and negative cash flows is presented. although optimization of bi-objective problems with due dates is an essential feature of real projects, little effort has been made in studying the p-mmrcpsp while due dates are included i...

Traditionally, the Resource Constrained Project Scheduling Problem (RCPSP) is investigated in the operations research literature from the makespan minimization perspective. However, a recent survey conducted in the United States revealed the surprizing fact that the majority of project planners consider maximization of the quality of project schedules as the most important objective (Icmeli Tuk...

An Evolutionary algorithm for resource constrained project scheduling (RCPS) problem is proposed with the objective to minimize project duration (makespan). The algorithm is tested with standard data sets given by Kolisch library for J30 and J60 and found to be performing well. General Terms Project Scheduling, Resources.
