Introduction: In recent years, many national and international expert groups have considered specific improvements in risk assessment of chemical pollutants. This study considered to assess the risk of workers exposure to air pollutants in an automobile manufacturing in order to evaluate the health risk assessment due to the inhalation exposure. Material and Method: To perform this study, ...
Abstract: Demand response (DR) is a key technique in smart grid (SG) technologies for reducing energy costs and maintaining the stability of electrical grids. Since manufacturing is one of the major consumers of electrical energy, implementing DR in factory energy management systems (FEMSs) provides an effective way to manage energy in manufacturing processes. Although previous studies have inv...
background: automobile manufacturing industries are considered among the main sites where accidents are likely to happen. from a cognitive point of view, stress can cause problems such as poor concentration, absent-mindedness, and hesitancy while making decisions. this study examines the relationship between job stress and occupational accidents in an automobile manufacturing company. methods: ...
Looking forward in 1995, automobile manufacturers identified a potential shift in customer preferences to lighter weight, fuel-efficient automobiles; fuel-cell powered cars; and hybrid gas/electric vehicles. To make existing cars more fuel efficient and to meet the coming needs of alternatively powered vehicles, automobile original equipment manufacturers (OEMs) needed lighter components. These...
Empirical validity of the claim that overhead costs are driven not by production volume but by transactions resulting from production complexity is examined using data from 32 manufacturing plants from the electronics, machinery, and automobile components industries. Transactions are measured using number of engineering change orders, number of purchasing and production planning personnel, shop...
This paper proposes a general mixture model framework for automobile warranty data that includes parameters for product field performance, the manufacturing and assembly process, and dealer preparation process. The model fits warranty claims as a mixture of manufacturing or assembly defects (quality problems) and usage related failures (reliability problems). The model also estimates the fracti...
