This paper presents the formulation and solution of the Combinatorial Multi-Mode Resource Constrained Multi-Project Scheduling Problem. The focus of the proposed method is not on finding a single optimal solution, instead on presenting multiple feasible solutions, with cost and duration information to the project manager. The motivation for developing such an approach is due in part to practica...

This paper discusses the problem of allocation of constrained renewable resource to splittable activities of a single project. If the activities of stochastic projects can be split, these projects may be completed in shorter time when the available resource is constrained. It is assumed that the resource amount required to accom-plish each activity is a discrete quantity and deterministic. The ...

PREFACE After having received my diploma from the Technische Universität Berlin in 1996, Rolf Möhring, the supervisor of my diploma thesis, offered me a research position in his group. At that time I was employed at a Berlin software company the head of which, Gert Scheschonk, strongly encouraged me to accept the offer. I accepted and in 1997 I began to work within a research initiative funded ...

In this paper, we present a new topic in connection with project scheduling. Since a limited work space can form a restriction to project scheduling problems, an efficient usage of these work spaces (or so-called spatial resources) is required to produce good project schedules. The requirement for the resource units of these spatial resources is in an adjacent manner (we cannot place a product ...

Project scheduling is the part of project management that deals with determining when intime to start (and finish) which activities and with the allocation of scarce resources to theproject activities. In practice, virtually all project managers are confronted with resourcescarceness. In such cases, the Resource-Constrained Project Scheduling Problem (RCPSP)arises. This optimization problem has...

The cumulative resource constraints of the resource-constrained project scheduling problem (RCPSP) do not treat the resource demands as geometric rectangles, that is, activities are not necessarily assigned to the same resource units over their processing times. In spite of this fact, most papers on resource-constrained project scheduling mainly in the motivation phase use a strip packing of re...

The purpose of this paper presents a heuristic method based in genetic algorithms (GA) for resource-constrained project scheduling. The problem studied was of the scheduling of projects that share the same pool of resources. This situation is very common in some environments of project, i. e., construction P&D units. Fluctuation in resource usage can result in many problems, such as the need in...

Resource-constrained project scheduling (RCPS) is often a challenging issue in practice, due to its combinatorial nature and uncertainty. This paper presents the framework of a heuristic approach to fuzzy RCPS problems using a fuzzy parallel scheduling method. This approach can handle both fuzzy and crisp numbers which commonly coexist in many realistic RCPS problems. Key-Words: Resource-constr...
