Effective use of labor, providing system flexibility, increasing productivity, decreasing lead times and costs are some of the most important factors influencing selection of material handling equipment. In this study, a decision support system (MHAD) considering these factors for material handling equipment selection is developed. MHAD consists of a database, a rulebased system and multi-attri...

In this article, we optimally solve an integrated production and material handling scheduling problem. Traditionally, scheduling problems consider machines as the only constraining resource. This is however no longer true as material handling equipment are becoming more and more valuable resources requiring important investments. Their operations should be optimized and above all synchronized w...

cell banking is long –term storing of cell stocks that requires intensive care and maintenance to ensure its adequate quality. the main goal of a biological bank is preparing a repository source of cell culture system in a global manner. on the other hand, cell culture is an invaluable tool for investigators in numerous fields. successful maintenance of cells requires knowledge and practice of ...

If a mobile mechanic has to travel for material, productive time is lost. This paper presents a novel method to reduce activities regarding material handling with extending of serving locations. The design of the supply system can be considered as a complex combinatorial optimization problem, where the goal is to find a route plan with minimal route cost, which services all the demands from the...

Background and Objectives: In the original in vitro method for evaluation of iron bioavailability using caco-2 cell model, ferritin formation by cells is considered as a functional indicator of both absorption and utilization of iron. However, as iron is measured in the tested material and then ferritin concentration is measured in caco-2 cell lysate, it is almost impossible to have a concrete ...

Carbon fiber-reinforced thermoplastics (CFRP) have excellent specific strength and rigidity, which has made them a popular material for lightweight construction. The growing demand plastics (FRP) leads to the problem of sustainable handling FRP at end their life cycle. aim research project was gain knowledge about shredding concerning optimal machine process design possible formation harmful, i...

background: today, the prevalence of musculoskeletal disorders is one of the health issues of concern in any society. one of the main causes of musculoskeletal disorders and conditions can be named unpleasant working conditions. the aim of this study was to report the prevalence of musculoskeletal disorders including working postures and lifting-related musculoskeletal disorders among workers o...
