This paper addresses a general class of nonpreemptive resource-constrained project scheduling problems in which activity durations are discrete functions of committed renewable and nonrenewable resources. We provide a well known 0±1 problem formulation and stress the importance of themodel by giving applications within production and operationsmanagement. Furthermore, we prove that the feasibil...

This paper presents a hybrid metaheuristic algorithm (HMA) for Multi-Mode Resource-Constrained Project Scheduling Problem (MRCPSP) in PERT networks. A PERT-type project, where activities require resources of various types with random duration, is considered. Each activity can be accomplished in one of several execution modes and each execution mode represents an alternative combination of resou...

This chapter reports on a new solution approach for the multi-mode resource-constrained project scheduling problem (MRCPSP, MPS|prec|Cmax). 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 b...

Multi-mode Resource Constrained Project Selection and Scheduling Considering the Reinvestment Strategy in a Flexible Time Horizon

Goal: The issue of resource allocation is a major concern for project engineers in the scheduling process project. Resources over-allocation are often seen practice after project, which makes unhelpful. Modifying an over-allocated schedule very complicated and requires lot effort time. Besides, during resource-constrained projects constructing companies, managers should more than one objective ...

Many studies on the resource-constrained project-scheduling problem have been published, but literature further considering multi-mode or multi-project issues often occurring in the real world is rather scarce. In this research, two heuristic algorithms are developed to solve a multi-mode resource-constrained multi-project scheduling problem (MMRCMPSP). The first, a parallel scheduling algorith...
