A construction contractor employs a force of skilled workers and has the limits set of special equipment, Assume that there are 6 categories of skilled workers and 5 classes of special equipment, the contractor has 3 construction project underway and has committed the company to complete dates for each of them .Certain job items (activities)are common the various projects and require the same inputs of labor and equipment. The activities occur on various dates throughout the time span from project completion.
However, the contractor does not have enough labor and equipment to work on these job items on the same day on all project.Hence,the contractor wants to scheduled (stagger)the specialized work force and specialized equipment on the projects so that (1)ideally no labor or equipment shortages exist on any day and (2) each project is done on time. If any shortages do exist, extra costs must be incurred for temporary workers or for equipment. A Predetermined payment has be received for each project. The contractor wants to keep construction costs to a minimum.
