This investigation presents a heuristic method for consumable resource allocation problem in multi-class dynamic Project Evaluation and Review Technique (PERT) networks, where new projects from different classes (types) arrive to system according to independent Poisson processes with different arrival rates. Each activity of any project is operated at a devoted service station located in a n...

The current market practices for most capital equipment manufacturers provide them with some special difficulties in production management tasks. These are, mainly: 1. Design changes during the necessary overlapping of the production process. 2. Some degree of uncertainty with supplier's due dates and quality specifications accomplishments. 3.

Most studies of project time estimation assume that (a) activity times are mutually independent random variables; many also assume that (b) path completion times are mutually independent. In this paper, we subject the impact of both these assumptions to close scrutiny. Using tools from multivariate analysis, we make a theoretical study of the direction of the error in the classical PERT method ...
