摘要:

This article proposes a new heuristic algorithm for minimizing part programs for numerical control (NC) punch presses. The part program contains the order in which the holes are punched into the part and the assignments of the tools to the indexing turret. The problem is broken down into two classical subproblems: the traveling salesman problem (TSP) and the quadratic assignment problem (QAP). By generating a feasible solution and then alternately improving the subproblems, good solutions are obtained in reasonable time. The algorithm is described, and then empirical results are given for applying the algorithm to real and randomly generated problems.

摘要:

The standby combustion turbine units in a nuclear generating station are periodically tested, and they are repaired if the test reveals a failure. The unique test procedure in this application is not accommodated by existing reliability models. In this paper, a stochastic model is developed, and the optimal time interval between two consecutive tests is computed. Comparisons with the current test practice suggest that improvements can be achieved in both the reliability and operating economy of such standby systems.

摘要:

Dynamic programming is a topic that is conceptually difficult from the standpoint of most industrial engineering students. The exercise, lucidly elaborated by Norman and Dixon, should thus be of particular benefit in conveying this subject in the classroom.
