Abstract
An unified approach is considered to the optimal allocation of human resources for the activities in a project. Project activities are broken down into work packages for functional organization and the work volume of these packages are estimated according to the characterization of the project engineering work, which are evaluated considering the severity of cost, schedule and quality. Since those work volumes include various grades of works, scheduled times and man-hours depend on the skills of available persons of engineers in the organization. In consideration of these circumstances, the human resource allocation can be actually realized and utilized. This article proposes the procedure to determine the optimal number of classified engineers required to perform those graded works, base on the evaluation of work volume in the specified work packages.
