A study of approximating the moments of the job completion time in PERT networks

Article Abstract:

An approach to find out the Time to Complete the Job (TCJ) determinant in Program Evaluation Review Technique (PERT) is derived. This particular approach factors in a dependency relationship which exists between paths. Concepts incorporated in critical path analysis are included in the model. Results of both simulated and empirical analysis show that the TCJ approximation made using the approach compares favorably with those of other researches.

An iterative local constraint based analysis for solving the resource constrained project scheduling problem

Article Abstract:

An iterative scheduling method that incorporates familiar dispatching rules and a decision-making methodology is derived as a solution to the problem posed by the existence of resource constraints in production scheduling. The algorithm utilizes scheduling passes that are characterized by consecutive forward and backward movements. Analysis of this algorithm using certain benchmarks shows that project duration is enhanced.

Efficient priority rules for the resource-constrained project scheduling problem

Article Abstract:

Analysis of the resource-constrained project scheduling method and its use of the RSM, which is one of several classical priority rules, shows that it is handicapped by the inability to truly represent the finiteness of available resources. Because of such a result, two priority rules are derived which are enhanced versions of the classical rules. These rules are really a variation of the Minimum SLacK priority rule.
