Project managers faced with this problem have to look for practical resource allocation strategies to minimize the project cost.
The proposed strategy is, first, to consider the cost of an allocated resource to a project not as a function of its use time, but rather as a measure of its real assignment duration to the project.
In project management, one generally recognizes that personnel resource management is more complex and drives particular requirements in scheduling.
Personnel resources are, for the most part, made up of specialized resources that are often rare and expensive and, incidentally, also represent the major part of the overall project cost.
It can include periods of inactivity not considered by traditional scheduling methods.
Therefore, the personnel management objective is to minimize these gaps, also minimizing the project cost. Paper presented at PMI® Research Conference: New Directions in Project Management, Montréal, Québec, Canada. Michel Gagnon, Ph D, PMP Project scheduling is traditionally resolved by means of the “Resource Constrained Project Scheduling” (RCPS) model (Ozdamar & Ulusoy, 1995). A method for integrating personnel into project schedule.For now, we introduce the concept of the assignment duration of a resource as the time interval of its participation to the project.So, the assignment of resources is generally made up of a continuous period.The solution of the model mainly supplies an activity schedule while optimizing a management objective.By analyzing this schedule, one notices the use rate of every resource type.The RCPS model, which belongs to the class of NP-hard problems (Blazewicz, Lentra, & Rinnooy, 1983), is best resolved by heuristic methods.However, these methods supply the first found schedule having the minimal project duration.This model describes project activities related by precedence constraints.Typically, each activity requires one or several resources from various categories, also known as resource types.
