Inspection policies : comparisons and modifications

Optimal sequential inspection policies

We consider the problem of combining a given set of diagnostic tests into an inspection system that can classify items of interest (cases) with maximum accuracy subject to budget constraints. One motivating application is sequencing diagnostic tests for container inspection problems, where the diagnostic tests may correspond to radiation sensors, documents checks, or imaging systems. We conside...

Counterterror and Counterdrug Policies: Comparisons

The problem of preventing repetitions of the September 11th incidents has begun to be called "the war on terror." This suggests analogies to the "war on drugs," and there have been attempts to use these comparisons to draw conclusions about the appropriate shape and likely success of the anti-terrorism campaigns (e.g., Massing, 2001). This essay identifies similarities and differences between t...

Learning Better Inspection Optimization Policies

Recent research has shown the value of social metrics for defect prediction. Yet many repositories lack the information required for a social analysis. So, what other means exist to infer how developers interact around their code? One option is static code metrics that have already demonstrated their usefulness in analyzing change in evolving software systems. But do they also help in defect pr...

A POMDP Framework to Find Optimal Inspection and Maintenance Policies via Availability and Profit Maximization for Manufacturing Systems

Maintenance can be the factor of either increasing or decreasing system's availability, so it is valuable work to evaluate a maintenance policy from cost and availability point of view, simultaneously and according to decision maker's priorities. This study proposes a Partially Observable Markov Decision Process (POMDP) framework for a partially observable and stochastically deteriorating syste...
