At the manufacturing plant or while products are being transferred from one supply layer to another, there is a considerable possibility of receiving damaged faulty items mixed in with non-defective commodities. This research focuses on and defective that shipped retailers by their suppliers. The retailer reworks make them non-defective, receives discount cost purchasing items. presented invent...

This research aimed to analyze the damaged products at PT. SIGNORE, Tangerang, Indonesia. A Fish Bone Diagram was drawn determine factor that causes defective products. Then, an action plan including concept of Five M checklist, 5W + 1H (What, Why, Where, When, Who, How) and seven new tools corrective plan, labor, machinery, materials, methods environment were developed. The purpose this study ...

A graph G is (j, k)-colorable if its vertices can be partitioned into subsets V1 and V2 such that in G[V1] every vertex has degree at most j and in G[V2] every vertex has degree at most k. We prove that if k ≥ 2j + 2, then every graph with maximum average degree at most 2 ( 2− k+2 (j+2)(k+1) ) is (j, k)colorable. On the other hand, we construct graphs with the maximum average degree arbitrarily...

The traditional inventory of the economic order quantity model assumes perfect items in an ordered lot and an infinite replenishment rate. However, such conditions are rare in actual production environments. Additionally, most studies of this problem have only considered suppliers offering the wholesaler a grace period. In practice, wholesalers often extend a fixed credit period to downstream c...

Technical limitations in image capturing usually impose defective, such as contrast degradation. There are different approaches to improve the contrast of an image. Among the exiting approaches, un-sharp masking is a popular method due to its simplicity in implementation and computation. There is an important parameter in un-sharp masking, named gain factor, which affects the quality of the enh...

The control of germline quality is critical to reproductive success and survival of a species; however, the mechanisms underlying this process remain unknown. Here, we demonstrate that elongation factor 2 kinase (eEF2K), an evolutionarily conserved regulator of protein synthesis, functions to maintain germline quality and eliminate defective oocytes. We show that disruption of eEF2K in mice red...

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...
