EX8-7 (Static) You have prepared the following schedule... You have prepared the following schedule for a project in which the key resource is a tractor. There are three tractors available to the project. The resource requirements are as shown in the diagrams below. Develop a resource-constrained schedule. Use the parallel method and heuristics given. Be sure to update each period as the computer would do.

Any resource scheduled beyond the shaded area will delay the project. "TP" stands for time period.
