By targeting enforcement efforts on specific segments of the regulated community, greater compliance with environmental regulations can be achieved. In this paper, the inspection minimizing targeting scheme with two groups is derived. Firms are moved at random into the target group, while escape from the target group occurs only when an inspection reveals the firm is in compliance. The optimal ...

The problem of automated defect detection in textured materials is investigated. A new approach for defect detection using linear FIR filters with optimized energy separation is proposed. The performance of different feature separation criteria with reference to fabric defects has been evaluated. The issues relating to the design of optimal filters for supervised and unsupervised web inspection...

Manufacturing products with multiple quality characteristics is always one of the main concerns for an advanced manufacturing system. To assure product quality, finite automatic inspection systems should be available and employed. Inspection planning to allocate inspection stations should then be performed to manage limited inspection resources. Since product variety in batch production or job ...

When production yield is random and demand needs to be satisfied in full, several production runs may need to be attempted until the number of usable products is sufficient. The tradeoff is then between using small lots possibly incurring setup cost many times and large lots which may result in costly overproduction. We generalize this problem to include inspection costs and show how to compute...
