Call admission control schemes and ATM network topological design

Article Abstract:

Call admission schemes are found to be a significant factor in determining asynchronous transfer mode network costs, suggesting that topological design may be used to determine appropriate call admission control schemes. Two schemes are compared with results showing the Reflected Brownian Motion-based scheme, incurring costs that are 10% to 30% lower than the equivalent bandwidth-based call admission control scheme.

A hybrid three-stage flowshop problem: efficient heuristics to minimize makespan

Article Abstract:

Two heuristic procedures were formulated to resolve a job scheduling problem, which is NP-complete, of a three-stage hybrid flowshop. Application of the two heuristics in various problem sizes revealed their effectiveness in lessening the makespan in a three-stage hybrid flowshop. The two heuristics procedures were able to generate a relative error less than 1% of the lower bound.

Chance-constrained programming in activity networks: a critical evaluation

Article Abstract:

The chance-constrained programming (CCP) model is reviewed for event realization in activity networks (ANs). A classification scheme of scholastic programming is presented in relation to CCP.
