In a globally competitive environment, sustaining high yield with a minimum number of quality controls is key for manufacturing plants to remain competitive. In modern semiconductor manufacturing facilities, with the moves to ever smaller geometries and the variety among products to be run concurrently, designing efficient control plans is becoming increasingly complex. Since a 100% of inspecti...

Abstract The efficiency of the measuring tools and operators is a significant part lot sentencing decisions. These have to pass some pre-specified quality levels avoid problems during assessment scenarios. measurements serious risk be encountered with any extent ambiguity, doubt, or indeterminacy due factors like variation among operating regimes, warming effects in hot climatic conditions, ope...

In the manufacturing processes, quantities like the proportion of defective units in a production lot may not be precisely known and most of the times the practitioners have to compromise with some imprecise (approximate) values. Prior knowledge of such quantities is required to evaluate the quality of a produced lot. In this paper, the properties of single sampling plan under situations involv...

The classical economic production quantity (EPQ) model is a well-known and commonly used inventory control technique. Common assumptions in this model are that all units produced are of perfect quality and shortage is not allowed, since in practice shortage, non-conforming product or scrap items are possible, these assumptions will underestimate the actual required quantity. The objective of th...

This paper reports on an active SLAM framework for performing large-scale inspections with an underwater robot. We propose a path planning algorithm integrated with visual SLAM that plans loop-closure paths in order to decrease navigation uncertainty. While loop-closing revisit actions bound the robot’s uncertainty, they also lead to redundant area coverage and increased path length. Our propos...

We present several new contributions in sampling-based coverage path planning, the task of finding feasible paths that give 100% sensor coverage of complex structures in obstaclefilled and visually occluded environments. First, we establish a framework for analyzing the probabilistic completeness of a sampling-based coverage algorithm, and derive results on the completeness and convergence of e...

We propose an airborne inspection system which operates with a single camera. It provides live high-resolution detail images at low framerates for inspection, interleaved in time with several coarse-resolution overview images suitable for visual servoing. By defining the object of interest in 3D, the same pose estimation routine can be used for visual servoing and object tracking, which saves c...
