چکیده
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 based on sound arguments. # 2003 Elsevier Science Ltd and IPMA.

Resource Constrained Project Scheduling with Material Ordering: Two Hybridized Meta-Heuristic Approaches (TECHNICAL NOTE)
Resource constrained project scheduling problem (RCPSP) is mainly investigated with the objective of either minimizing project makespan or maximizing project net present value. However, when material planning plays a key role in a project, the existing models cannot help determining material ordering plans to minimize material costs. In this paper, the RCPSP incorporated with the material order...
متن کاملAN EXPERIMENTAL INVESTIGATION OF THE SOUNDS OF SILENCE METAHEURISTIC FOR THE MULTI-MODE RESOURCE-CONSTRAINED PROJECT SCHEDULING WITH PRE-OPTIMIZED REPERTOIRE ON THE HARDEST MMLIB+ SET
This paper presents an experimental investigation of the Sounds of Silence (SoS) harmony search metaheuristic for the multi-mode resource-constrained project scheduling problem (MRCPSP) using a pre-optimized starting repertoire. The presented algorithm is based on the time oriented version of the SoS harmony search metaheuristic developed by Csébfalvi et al. [1] for the single-mode resource-con...
متن کاملA multi-objective resource-constrained project scheduling problem with time lags and fuzzy activity durations
The resource-constrained project scheduling problem is to find a schedule that minimizes the project duration subject to precedence relations and resource constraints. To further account for economic aspects of the project, one may add an objective of cash nature to the problem. In addition, dynamic nature and variations in real world are known to introduce uncertainties into data. Therefore, t...
متن کاملA Preemptive multimode resource constrained project scheduling model with cash flows
Resource constrained project scheduling problem is one of the most important issues in project planning and management. The objective function of this problem is to minimize the completion time of a project. When there is budget constraint or high risk for investment, using the criteria such as cash flows is so important. The development of computer systems and processors makes it possible to t...
متن کاملA New Bi-Objective Model for a Multi-Mode Resource-Constrained Project Scheduling Problem with Discounted Cash Flows and four Payment Models
The aim of a multi-mode resource-constrained project scheduling problem (MRCPSP) is to assign resource(s) with the restricted capacity to an execution mode of activities by considering relationship constraints, to achieve pre-determined objective(s). These goals vary with managers or decision makers of any organization who should determine suitable objective(s) considering organization strategi...
