In today’s competitive market, those producers who can quickly adapt themselves todiverse demands of customers are successful. Therefore, in order to satisfy these demands of market, Mixed-model assembly line (MMAL) has an increasing growth in industry. A mixed-model assembly line (MMAL) is a type of production line in which varieties of products with common base characteristics are assembled o...

Design of assembly line is done in order to more coordinate a collection of some consecutive work stations for the aim of obtaining more productivity from the work stations and workers. The stations are arranged in a way to have a continuous and constant material flow. In this paper a multi-objective formulation for assembly line balancing is introduced. As a solution approach a two-step approa...

In this paper, an analytical approach is used for assembly line rebalancing and worker assignment for single and mixed-model assembly lines based on a heuristic-simulation algorithm. This approach helps to managers to select a better marketing strategy when different combinations of demands are suitable.Furthermore, they can use it as a guideline to know which worker assignment is better for ea...

The productivity of assembly lines is considerably affected by the health condition of assembly workers, and work-related musculoskeletal disorders (WMSDs) are common occupational diseases among assembly workers due to repetitive motions or heavy working loads. The conventional approaches to decreasing WMSD risks in the assembly lines include slowing the work-pace or applying job rotations. The...

According to researches, one of the productivity barriers among many organizations is assembly line balancing problem, which needs scientific models to be solved. This paper examines the effect of line balancing on the functioning of assembly line in two sections. In the first section, after studying the theoretic bases and reviewing the literature, we have discussed the assembly concepts, diff...

Background: Musculoskeletal disorders are the most common occupational injuries and constitute a huge global health problem with substantial economic and human cost as well as negative impact on the quality of life. The aim of this study was to determine the prevalence of musculoskeletal disorders and level of risk among the workers of the assembly line of a battery factory. Methods: In this...

Background: Although the expansion of innovation in the industry has led to an increase in the fast of works, production and productivity, it has also imposed an increase in the incidence of musculoskeletal disorders. So, the aim of this study was determination the risk level of work posture by REBA and RULA method among workers of assembly line of a cosmetic manufacturing factory. Methods: Th...

Assembly lines are manufacturing systems in which a product is assembled progressively in workstations by different workers or machines, each executing a subset of the needed assembly operations (or tasks). We consider the case in which task execution times are worker-dependent and uncertain, being expressed as intervals of possible values. Our goal is to find an assignment of tasks and workers...
