An approach which combines PERT and CPM in one model to solve project scheduling problems, is introduced. Due to the stochastic nature of activity time and cost for PERT and CPM networks, robust design for project scheduling via statistical method is introduced in the presented approach. The statistical method, such as response surface methodology (RSM), is used to develop a rationale of the time-cost...
We consider the problem of optimal allocation of measurement resources, when: (1) the total measurement budget and time duration of measurements are fixed, and (2) the cost of an individual measurement varies inversely with the (controllable) measurement accuracy. The objective is to determine the time-distribution of measurement variances that minimizes a measure of error in estimating a discrete-time,...
Optimal program module distributions are determined for a parallel workload to be run on the processors of a homogeneous multiple-processor system. The optimization minimizes a weighted combination of cost and performance metrics: workload completion time, processors total idle time, execution cost, communication cost and load imbalance. The time-related metrics are formulated based on a realistic...
