Multi-manned assembly lines are often designed to produce big-sized products, such as automobiles and trucks. In this type of production lines, there multi-manned workstations where a group workers simultaneously performs different operations on the same individual product. One problems, that managers usually encounter, is optimal number items using fixed workstations, without adding new ones. paper, class namely, line balancing problem addressed, with objective minimising cycle time. A...

Two-sided assembly line balancing problems usually occur in plants producing large-sized high-volume products such as automobiles, buses or trucks. The difference between these kinds of lines and traditional is that there the possibility installing two parallel single stations each position so workers can work simultaneously on different tasks one same product. In this paper, cost-oriented two-sided problem addressed. This kind occurs final which manufacturing process very labour intensive....

Purpose This paper aims to study a generalized type of mixed-model assembly line with multi-manned workstations where multiple workers simultaneously perform different tasks on the same product. special kind is usually utilized assemble models large products, such as buses and trucks, production line. Design/methodology/approach To solve balancing problem optimally, new mixed-integer-programming (MIP) model presented. The proposed MIP nondeterministic polynomial-time (NP)-hard, result,...

Multi-manned assembly lines are usually found in plants producing large-sized high-volume products such as automotive sector. In this paper, the balancing problem of kind with skilled workers is addressed. A new mixed integer programming formulation presented to solve optimally objective minimizing total operating cost line. The main advantage proposed model allow each multi-manned workstation perform different tasks same product simultaneously. has been used some experimental problems...

Highway-rail grade crossing (HRGC) accidents pose a serious risk of safety to highway users, including pedestrians trying cross HRGCs. A significant increase in the number HRGC globally calls for greater research efforts, which are not limited analysis at HRGCs but also understanding user perception, driver behavior, potential conflicting areas crossings, effectiveness countermeasures and perception towards them. is one priority State Florida, since state experienced total 429 injuries 146...

In this paper, the capacitated dynamic lot sizing problem in integrated manufac-turing/remanufacturing systems is addressed. These kinds of production are designed to satisfy demands different classes single-level products not only by manufacturing raw materials, but also remanufacturing returned products. A single machine with a limited capacity each time period used perform both and operations. mathematical programming formulation proposed optimally solve problem. Since NP-hard (it...

Multi-manned assembly lines are often designed to produce large-sized products, such as automobiles, trucks and buses. In this type of production lines, usually there multimanned workstations where a group workers simultaneously performs different operations on the same individual product. One problems, that managers encounter, is optimal number items using fixed workstations, without adding new ones in order meet market demand. paper, class line balancing named multi-manned problems II, has...

Multi-manned assembly line balancing problems are usually occurred in plants producing large-sized high-volume products such as automobiles and trucks. In this paper, a cost- oriented objective function is presented for multi-manned problem. This kind of may be used to balance final lines which manufacturing process very labor intensive. A mixed-integer mathematical programming model proposed solve the problem optimally. The formulation has been some small size by considering both...

Multi-sided assembly line balancing problems usually occur in plants producing big-sized products such as buses, trucks, and helicopters. In this type of line, each workstation, it is possible to install several workplaces, which a single operator performs his/her own set tasks at an individual mounting position. way, the operators can work simultaneously on same product without hindering other. This paper considers for first time multi-sided problem with objective minimising cycle time,...

The capacitated dynamic lot sizing problem with product returns in a closed remanufacturing system is addressed this paper. designed to satisfy the demands of different classes single level products by end-life returned products. A machine limited capacity each time period used perform operations. mathematical programming formulation proposed for considered problem: model minimizes sum costs over finite planning horizon. generalized version classical problem, and thus it NP-hard itself....

Scheduling for job shop is very important in both fields of production management and combinatorial optimization. Since the problem well known as NP-Hard class, many metaheuristic approaches are developed to solve medium large scale problems. One main elements these metaheuristics solution seed structure. Solution represent coding structure real solution. In this paper, a new scheduling presented. This compared with famous presented scheduling. Tabu search algorithm The proposed examined...

Multi-manned assembly line balancing problems (MALBPs) can be usually found in plants producing large-sized high-volume products such as automobiles and trucks. In this paper, a cost-oriented version of MALBPs, namely, CMALBP, is addressed. This class may arise final lines which the manufacturing process very labor-intensive. Since CMALBP NP-Hard, heuristic approach based on tabu search algorithm developed to solve problem. The proposed uses two neighborhood generation mechanisms, namely...
