Specialized inspection problems in serial production systems

Article Abstract:

Formulations of the specialized inspection problems in serial manufacturing systems were studied to understand how to minimize the effects of defects on the goals of total-cost minimization, profit maximization and minimization of undetected defective units. Specialized inspection stations refer to stations that detect defects produced in specific operations. The exact or heuristic solutions to these formulations and some computational experiences are presented.

Multiobjective routing of hazardous materials in stochastic networks

Article Abstract:

The Stochastic, Multiobjective Shortest Path algorithm for determining sets of non-dominated routes in a network containing multiple and uncertain measures of route evaluation was evaluated. A key concept of the algorithm was the use of multiobjective dominance representations for indefinite attribute probability distributions. The use of the technique for hazardous materials transportation application in New York state was also presented.

Optimal yield improvement in multi-stage manufacturing systems

Article Abstract:

A decomposition procedure for optimizing the quality of a multiple-stage manufacturing line with inspection stations is introduced. The model, which decomposes the system into two models representing no inspection between stages and 100% inspection after each stage, looks at process improvement as a step-wise yield improvement task that maximizes the probability of successfully processing an item.
