During textile manufacturing processing, it is vital to inspect, detect, assess and rectify defects as soon as they emerge. This is particularly important for fabric engineering and finishing, as the fabric quality directly affects the quality of their final products. In textile industry history, visual inspection and classification were common practice. The nature of traditional manual inspect...

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...

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...

Abstract: This paper studies multi-product production manufacturing systems with in-line quality control. Quality control is carried at inspection stations located within a production line. Quality control has an impact on performance of the system: throughput decreases and resource utilization increases. Production lines are modeled as a multi-product Open Jackson Network, where stochastic cha...

Quality inspection of gluing quality in inner threads of bearing sleeve of harddisk-drive is an important step in spindle motor assembly. This paper presents an automated inspection system based on machine vision for quality control of gluing quality. At present, the inspection process is performed by human inspectors. However, they have low throughput and cannot identify all defects. To increa...

Today’s software quality assurance techniques are often applied in isolation. Consequently, synergies resulting from systematically integrating different quality assurance activities are often not exploited. Such combinations promise benefits, such as a reduction in quality assurance effort or higher defect detection rates. The integration of inspection and testing, for instance, can be used to...
