In this paper the multiple projects resourceconstrained project scheduling problem is considered. Several projects are to be scheduled simultaneously with sharing several kinds of limited resources in this problem. Each project contains non-preemptive and deterministic duration activities which compete limited resources under resources and precedence constraints. Moreover, there are the due dat...

Purpose – The purpose of this paper is to present the MEMORAe project, the goal of which is to offer an alternative to the loss of competencies and knowledge in an organization. Design/methodology/approach – Within the project MEMORAe, interest was focused on the capitalization of knowledge and competencies in the context of an organization. The E-MEMORAe environment was developed based on the ...

this paper presents a multi-objective resource-constrained project scheduling problem with positive and negative cash flows. the net present value (npv) maximization and making span minimization are this study objectives. and since this problem is considered as complex optimization in np-hard context, we present a mathematical model for the given problem and solve three evolutionary algorithms;...

Software project planning is becoming more complicated and important as the size of software project grows. Many approaches have been proposed to help project managers by providing optimal staffing and scheduling in terms of minimizing the salary cost or duration. Unfortunately, the software quality, another critical factor in software project planning, is largely overlooked in previous work. I...

In a recent paper Wei, Liu and Tsai present an ‘‘advanced TOC method for project scheduling under resource constraints’’. In this note we demonstrate that the authors (a) largely ignore the state of the art in resource-constrained project scheduling, (b) do not offer a correct application of the critical chain scheduling concepts, and (c) describe an alternative scheduling approach that is not ...

My paper discusses system consequence, which is a central idea in the project to lift the theory of information flow to the general level of universal logic and the theory of institutions. At the same time, it uses ideas from information flow to extend the theory of institutions. ICCS 2009, 26–31 July 2009 System Consequence Table of

“Planning and Scheduling in Manufacturing and Services” written by Michael L. Pinedo and published in the Springer Series in Operations Research is a recent book intended for a senior level or master level course on planning and scheduling either in an engineering or a business school. The book consists of four parts. Part I introduces the main features of scheduling models in manufacturing and...

Project preemption allows resources flow passively from one project or task to another. Due to high-cost and high-risk characteristics of software development, project preemption might have a significant impact on the ultimate completion time of a software project. This article examines the feasibility of the Taguchi’s parameter design to achieve robust resource assignment for multiple software...

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...
