On performance modeling of project-oriented production

A methodology has been developed in order to incorporate a performance perspective into production planning. The concept of project-oriented production has been used to emphasize a hierarchical structure for analysis and decision making. Based on a new type of resource workload model, the methodology has been applied to estimate the speed-up of each project for different levels of the resources assigned to it. We introduce the notion of leverage to trade-off resource usage or efficiency with each project duration or makespan.
