In order to assure appearance quality of an industrial product, sensory inspection by human vision (visual inspection) is implemented in many manufacturing industries. This study focuses on the fact that the frequency of occurrence of defective products varies each time in production processes, and also considers the relationship between the mixing rate of the defective product and defect detec...

Strains carrying mutations in the maltose system of Escherichia coli were assayed for maltose taxis, maltose uptake at 1 and 10 muM maltose, and maltose-binding activity released by osmotic shock. An earlier conclusion that the metabolism of maltose is not necessary for chemoreception is extended to include the functioning of maltodextrin phosphorylase, the product of malP, and the genetic cont...

<p>Product quality depends on adequate human resources, methods, raw materials, environment, equipment and machinery. PT. XYZ has implemented a product control system with the aim that products produced are in accordance established standards. Through control, it is hoped company can improve effectiveness of preventing occurrence defective products. fault tree analysis method order to pro...

Smart factories merge various technologies in a manufacturing environment order to improve factory performance and product quality. In recent years, these smart have received lot of attention from researchers. this paper, we introduce defective classification system based on deep learning for application factories. The key component the proposed is programmable logic controller (PLC) artificial...

In this article we studied Nielsen coincidence theory for maps between manifolds of same dimension without hypotheses on orientation. We use the definition of semi-index of a class, we review the definition of defective classes and study the appearance of defective root classes. We proof a semi-index product formula type for lifting maps and we presented conditions such that defective coinciden...

in this paper, the study deals with the lead time and setup reduction problem in the vendor-purchaser integrated inventory model. the cost of capital (i.e., opportunity cost) is one of the key factors in making the inventory and investment decisions. lead time is an important element in any inventory system. the proposed model is presents an integrated inventory model with controllable lead tim...

We study a problem of lot-sizing and sequencing several discrete products on a single machine. A sequence dependent setup time is required between the lots of different products. The machine is imperfect in the sense that it can produce defective items, and furthermore, it can break down. The number of the defective items of each product is given as an integer valued non-decreasing function of ...

Quality control is one of the industrial tasks most susceptible to be improved by implementing technological innovations. As an innovative technology, machine vision enables reliable and fast 24/7 inspections helps producers improve efficiency manufacturing operations. The accessible data equipment will used identify report defective products, understand causes deficiencies allow rapid efficien...
