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.

Use the following order of heuristics: 1. Minimum slack, 2. Smallest duration, 3. Lowest identification number

Note: Recall, in the schedule resource load chart the time-constrained scheduling interval (ES through LF) has been shaded. Any resource scheduled beyond the shaded area will delay the project. "TP" stands for time period.

How long will the project take if it was NOT resource-constrained?

How long will the resource-constrained project take?
