Optimal project duration for resource leveling

Resource Leveling in Fuzzy Project Scheduling

In this paper a new method based on fuzzy theory is developed to solve the Project Resource Leveling Problem in fuzzy environment. Resource Leveling Problem attempts to minimize the resource usage fluctuations in project plan. Assuming that the duration of activities and resource requirements are fuzzy, in this method we compute several project characteristics such as earliest times, latest tim...

A Multi-objective Scheduling Model for Solving the Resource-constrained Project Scheduling and Resource Leveling Problems

The project resource leveling problem was proposed to smooth resource usage and reduce resource fluctuation, while the resource-constrained project scheduling problem focuses on minimizing the project duration with limited resources. Solving the two interrelated problems separately is unlikely to result in a globally optimum schedule. The few integrated optimization methods that have been devel...

Flexible resource management and its effect on project cost and duration

In practice, most projects result in cost overruns and schedule slippage due to poor resource management. This paper presents an approach that aims at reducing project duration and costs by empowering project managers to assess different scenarios. The proposed approach addresses combinatorial modes for tasks, multi-skilled resources, and multiple calendars for resources. A case study reported ...

Constrained Consumable Resource Allocation in Uncertain Project Networks with Fuzzy Activity Duration

A THEORETICALLY CORRECT RESOURCE USAGE VISUALIZATION FOR THE RESOURCE-CONSTRAINED PROJECT SCHEDULING PROBLEM

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...
