incorporating capacity into schedule construction
Virtually all projects have limited capacity or resources. Therefore, the success of a project is tied to how well the resources are managed and how well the project is scheduled. The traditional methods of project scheduling have been either the Critical Path Method (CPM) or the Gantt chart. However, Critical Path Analysis is limited in its assumption that projects have infinite capacity. A new method of project scheduling has been proposed that incorporates finite capacity of labor, capital equipment, facilities and material into its scheduling formula. Resource scheduling incorporates decisions about capacity into the scheduling process using two methods: time constrained and resource-constrained. Time-constrained scheduling uses time factors as its critical variable, while resource-constrained focuses on the limited capacity of resources, with emphasis on resolving capacity overload problems.
