ABSTRACT
Before resource scheduling can be carried out on a more realistic scale, the project manager or planner will be faced with a number of questions that either raise problems or force decisions. In the engineering design for large petrochemical or construction projects it would probably be necessary to schedule work and headquarters manpower resources for each of the main engineering disciplines. The reason is that each of the activities is likely to be very small in relation to the total workload of hundreds or thousands of other manufacturing activities. Many programs will allow resources to be specified in terms of man-hours, both as the daily requirement and as the availability. If the software cannot accept decimal quantities, it is necessary to resort to tricks. Factoring is one solution that has been found effective. The use of most, if not all, resources in a project schedule can usually be considered as rate-constant.
