Employing more than one supplier and splitting orders between them is a strategy employed in supply chains to lessen the lead-time risk in unstable environments. In this paper we present a multiple-sourcing inventory system with stochastic lead-times and constant demand controlled by a continuous review, reorder point-order quantity inventory policy. We consider the situation in which the order...

Well written and organized, the paper by Zopounidis and Doumpos suggests to us the following questions: (a) whether or not the multiple criteria decision aid (MCDA) approaches are realistic and convincing in environments of Simon’s bounded rationality; (b) whether or not the MCDA approaches rely on assumptions which are in accordance to (or at least, are not in contradiction to) principles firm...

Frequently the most computationally intensive part of a program is attributed to the nested loops it contains. It is therefore of interest to try to parallelize the nested loops in order to reduce the overall computation time. A special category of FOR(DO) nested loops are the uniform dependence loops, which yield efficient parallelization techniques and are the focus of this paper. The primary...

This quotation seemed a proper note with which to begin on a subject that has made monkeys of most of us at one time or another. The struggle to find a suitable configuration for system power, ground, and signal returns too frequently degenerates into a frustrating glitch hunt. While a strictly experimental approach can be used to solve simple problems, a little forethought can often prevent se...
