Operational-level scheduling decisions on the factory floor include the release policy and the dispatching rule. Recent work by researchers suggests that factory performance depends heavily on the release policy. Several heuristic factory release rules have been developed that generate release decisions based on the status of the bottleneck machine. The heuristic rules perform very well in redu...

Plant factory is known as the closed controlled plant production systems with the artificial lighting. Environmental factors have been concerned as the most important factors to influence quality of product in plant factory. One of the most applicable technologies for optimizing plant production system in plant factory is Infotronics. In the plant factory, Infotronics is defined as a combinatio...

BACKGROUND Microscopic fungi are the biological agent of occupational risk in the woodworking environment. Microbiological and chemical methods were used for determination of their concentration and species composition in dust. MATERIAL AND METHODS Dust was sampled in 3 factories producing furniture using different materials. The 1st factory (A) processes solid wood, the 2nd (B) - chipboards ...

The socialist factory, as the 'incubator' of the new socialist (wo)man, is a productive entry point for the study of socialist modernization and its contradictions. By outlining some theoretical and methodological insights gathered through field-research in factories in former Yugoslavia, we seek to connect the state of labour history in the Balkans to recent breakthroughs made by labour histor...

The impressive performance of current (KEKB) and recent (PEP-II) B-Factory colliders has increased interest in developing even higher luminosity B-factories. Two new designs are being developed (SuperKEKB and SuperB). Both designs plan to deliver a luminosity in the range of 1×10 cms, nearly 100 times the present B-factory level. Achieving this high luminosity requires high-current beams and sh...

The AEFTA (Application Enabler Technology for Factory Automation) experiment, which involves Digital Equipment Corporation, Politecnico di Torino and SYCO, with staff of seven, develops a factory automation product using BASEstar Open (1990) and object technology, notably OMT (Rumbaugh et al. 1991), G++ (Menga et al. 1993) and C++. The goal of the application experiment is to verify if object o...

This paper describes a virtual factory in which almost any manufacturing process can be deened, modelled, and then carried out. The results of this are designs of the components manufactured (in the form of geometric models) and part programs and process plans for their manufacture. Both of these can subsequently be reloaded into the virtual factory and amended and enhanced, or|in the case of t...

background: heavy metals (hms) are one of the most important polluting substances emitted to the environment during cement production. tehran cement factory located in the southeastern of tehran, iran, closer to agricultural lands cultivates alfalfa, barley, and maize as feed. the objective of the study was to determine the concentration of hms in agricultural soils. methods: thirty six soil sa...

In this era of digital technology and network communications, paper-based data management can be a bottleneck, slowing factory-wide information transfer. This study explores the evolution of paperless communication in a factory environment and reviews some of the key technologies that contribute to the implementation of a paperless system including digital communication, the virtual factory, co...
