Increasing the amount of inspection activities and inspecting a large fraction of the items are two approaches that are used to improve products’ quality. In this paper, as in a precedent article by Jaraiedi, et al.[5], 100% inspection in combination with multiple-criteria decision (MCD) response is considered. Three different inspection procedures for the multi-stage inspection are presented. ...

This paper presents a degradation-based model to jointly determine the optimal burn-in, inspection, and maintenance decisions, based on degradation analysis and an integrated quality and reliability cost model. Degradation modeling plays an important role in reliability prediction and analysis for many highly reliable components and equipment, when the failures can rarely be observed. Unlike tr...

Quality is a key factor in business success, growth, and competitive position. One of the essential factors in quality control is the inspection task, particularly the search portion. Eye-tracking technology is a very useful tool in capturing information about the eye movements in relation to visual inspection parameters. To investigate the effect of eye movements on inspection performance, thi...

Studies have shown that neither humans nor automation can achieve superior inspection system performance; hence, hybrid inspection systems where humans work in conjunction with machines have attracted research. Over the years, performance of inspection systems has been evaluated using traditional measures of speed, and accuracy. However, human trust plays an important role, influencing the resp...

In this paper we present an approach for quality inspection and quality improvement of spatial data that is based on map matching and map fusion. Two different datasets (GDF/TeleAtlas and OpenStreetMap) are used in this study. At first, the edges in the two datasets are matched manually with a tool developed in VBA and ArcGIS. Then, the form of the matching pairs in both datasets is calculated ...

In practices, not only production but inspection processes are often not perfect, thereby generating defects and inspection errors. Previous imperfect-quality inventory studies, however, have mostly focused on developing cost-minimizing models that do not consider imperfect inspection processes and related defect sales return issues despite their practical significance. Thus, this study propose...

Bean constitutes, with rice, the staple diet of the Brazilian people. The quality control of beans includes computing the percentages of different varieties present in a batch of beans. The selling price of the batch depends on these percentages. In this work, we propose a computer system for visual inspection of beans. We use “correlation-based multi-shape granulometry” for the first time to s...

The software inspection process was created for the dual purpose of improving software quality and increasing programmer’s productivity. Formal inspection is a better method than technical walkthroughs in the software life cycle process. benefits gained in the development of defect-free software by utilizing formal inspection Formal inspections may be applied to any product or partial product o...

In high volume productions based on casting processes, like high-pressure die casting (HPDC) or injection moulding, there is a wide range of variables that affect the end quality of produced parts. These variables include production parameters (temperature, pressure, mixture), and external factors (humidity, temperature, etc.). With this many variables it is a challenge to maintain a stable out...
