The demand for automatic quality inspection of individual micro components increases strongly in micro optoelectronics industry. In many cases, quality inspection of those micro components needs dexterous microhandling. However, automatic dexterous handling of micro components is a very challenging issue which is barely explored. This paper presents a high-DOF (degrees of freedom) automatic dex...

An economic, cost of quality model is formulated for a production system with multiple inspection locations and sampling. The model is applied to a thermal printer for digital photographs to determine when inspection of incoming material is appropriate. A simple dynamic model of quality is used, allowing for common-cause defects and the evaluation of sampling plans. The opportunity to correct q...

This paper presents the development of inspection strategies dedicated to the quality insurance of the wind turbine blade manufacturing process and in particular the inspection of the adhesive bondlines. Ultrasonic testing is recognized as a technique that can provide valuable information about the structure. Porosity, dry area and delamination can be detected and characterized in laminates. La...

An important aim of automation is to increase productivity and to decrease costs. In the past automation was mainly focused on steering and controlling motions and operation sequences. In many cases the sensory capabilities of automated production systems are underdeveloped and quality inspection is still carried out manually and visually. By using automated visual inspection systems and digita...

This research presents three profit sharing models of a key item in a two-echelon supply chain production. The first model maximizes the supplier’s profit while allowing the producer to take his own optimal inspection sampling policy. The second model is developed exclusively to the supplier’s advantage. The last model adopts a collaborative strategy that permits both parties to negotiate an in...

A significant amount of software is developed all over the world by small and medium size software organizations. These organizations do not have enough infrastructures and resources to implement an austere quality plan. Software inspection is a fundamental component of the software quality assurance process. Formal review methods are rigorous and their implementation is cumbersome for small an...

Conventional eddy current using single-frequency excitation has limited material characterization capabilities. Enrichment of the spectral information of the signal with techniques such as multifrequency or swept frequency inspection could be employed to improve the inspection process. Broadband excitation is also implemented with time-domain inspection using pulsed eddy current PEC. The spectr...

Quality of rice is defined from its physical and chemical characteristics. Quality of grains is required for protecting the consumers from substandard products because the samples of food materials are subjected to adulteration. This paper provides a solution to the problem of the rice industry for quality analysis. Computer Vision based Inspection provides one alternative for fast, accurate, c...

The traditional construction industry dilemma concerns the definition of an overall quality standard and acceptable level especially in aesthetic issue because some work items in visual inspection are difficult to measure the absolute defect quantity. These are limited by using human vision inspection. In current practice, the visual quality inspection is still relied on individual subjective j...

This paper addresses an automatic knowledge discovery process from a database of images in a context of Automated Visual Inspection (AVI). AVI is the field of computer vision addressing quality inspection of industrial products, even under informal quality models. When modelling informal knowledge, one of the most critical point turns out to be the correct and efficient translation of human exp...
