In project scheduling, many problems can arise when resource fluctuations are beyond acceptable limits. To overcome this, mathematical techniques have been developed for leveling resources. However, these produce a hard and inflexible approach in scheduling projects. The authors propose a simple resource leveling approach that can be used in scheduling projects with multi-mode execution activit...

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...

In this paper, we consider scheduling of project networks under minimization of total weighted resource tardiness penalty costs. In this problem, we assume constrained resources are renewable and limited to very costly machines and tools which are also used in other projects and are not accessible in all periods of time of a project. In other words, there is a dictated ready date as well as a d...
