Abstract:

Many production facilities rely on the intuition of the quality assurance inspector for determining what will be visually inspected and for what length of time on a finished product. In this thesis a model for visual inspection of a finished product is developed. The key parameters in the model are the probability of worker error, the probability of inspector error, and the cost of system error. Paired comparisons of error phenomena from operational personnel are converted to probabilities using the indirect numerical estimation technique. The model is used in a goal program to optimize the use of inspector time in a production facility. The model and the goal program are applied to a military problem to demonstrate the broad applicability of the methodology. The military problem is the allocation of inspection time before firing an artillery weapon to insure accurate and timely delivery of projectiles. Keywords Goal programming.
