Production management aims to maximize profit by increasing salable output while reducing the cost related with inspection, where inspection is defined as the measurement and quality assessment of items produced. This study is based on a semiconductor production line with consecutive deteriorating machines. Each machine is inspected via the items it produces and an inspection result triggers a ...

Glass defects are a major reason for poor quality and of embarrassment for manufacturers. It is a tedious process to manually inspect very large size glasses. The manual inspection process is slow, time-consuming and prone to human error. Automatic inspection systems using image processing can overcome many of these disadvantages and offer manufacturers an opportunity to significantly improve q...

This paper describes the basic actions proposed for quality inspection. These actions involve structuring a Decision Supporting Expert System (DSES) to help with those decisions related to the preliminary activities for inspection development—most of them relating to determining of the need or convenience of carrying out the inspection itself. Once the opportunity to carry it out is defined, th...

Aerial photogrammetry is one of the main methods obtaining geospatial information. After entering the 21st century, aerial photogrammetry technology has fully entered the digital age, and the quality of digital aerial photography results will directly affect the quality and accuracy of results of surveying and mapping .Therefore, it is necessary to inspect the quality of digital aerial photogra...

The nature of input materials is changed as long as the product reaches the consumer in many types of manufacturing processes. In designing and improving multi-stage systems, the study of the steps separately may not lead to the greatest possible improvement in the whole system, therefore the study of inputs and outputs of each stage can be effective in improving the output quality characterist...

This note introduces the use of distributed polarization x-talk measurement for raw polarization maintaining fiber (PMF) quality inspection, PMF coil winding process monitoring, PMF coil adhesive curing and stress release monitoring, overall PMF coil quality inspection, and temperature induced stress determination. PMF birefringence temperature variation can also be precisely measured. The use ...

Software inspection is an effective way to assess product quality and to reduce the number of defects. In a software inspection the inspection meeting is a key activity to agree on collated defects, to eliminate false positives, and to disseminate knowledge among the team members. However, inspection meetings often require high effort and may lose defects found in earlier inspection steps due t...

Automated fabric inspection system is important to prevent delivering of inferior quality fabric and designed to increase the accuracy, consistency and speed of defect detection in fabric manufacturing process to reduce labor costs, improve product quality and increase manufacturing efficiency. Fabric inspection is still carried out offline and manually by humans with many drawbacks such as tir...

We define a framework for the evaluation of user interface construction tools in terms of six software engineering qualities. These qualities are understood in terms of who judges the quality – developer or end user; and what artifact is judged – the development tool itself or the systems it produces. We identify four classes of evaluation techniques: functional inspection, architectural inspec...

Color and size are two important attributes for quality evaluation of most food and bioproducts. Many of the quality factors affecting oil palm and white powder starch are determined primarily by visual inspection. Such inspections determined market price and to a certain extent consumers' preferences. However, the inspection of oil palm and white powder starch is a very repetitive and tedious ...
