Kinematic Model for Resource Constrained Projects Scheduling Problem with Under Uncertainties - A Space Segment Subsystem Case Study

摘要

The research on project scheduling problem was intensified from the recognition that network models CPM (Critical Path Method), PERT (Project Evaluation Review Technique) and PDM (Precedence Diagram Method) are based on the assumption that all needed resources will be available. The importance of project scheduling and control is bolstered with many examples where the inadequate scheduling and control are often identified as the most common causes of project failure. Throughout systems life cycle, the techniques and approaches are mainly involved in the planning, programming and control of project activities conducted in context of resource constrained under uncertainties. In addition of scenarios the complexity of the projects, there are some classes of products, typical of the aerospace systems, which are problematic for current methods of resource constrained project scheduling under uncertainty. The existing methods fail because they suffer from one or more of the following limitations: focused mainly on the basic RCPSP (Resource Constrained Project Scheduling Problem) model; dealing with only one source of uncertainty, mostly in duration of activities; and do not model uncertainties.
