Automobile sector forms the backbone of manufacturing sector. Vehicle assembly line is important section in automobile plant where repetitive tasks are performed one after another at different workstations. In this thesis, a methodology is proposed to reduce cycle time and time loss due to important factors like equipment failure, shortage of inventory, absenteeism, set-up, material handling, r...

the aim of this study was to evaluate the effectiveness of individual-focused stress management training namely deep breathing exercise (dbe) on self-perceived occupational stress among male automotive assembly-line workers.a quasi-experimental study was conducted at 2 automotive assembly plants in malaysia over 9 months, from january 2012 to september 2012. assembly-line workers from plant a r...

In this paper, the problem of sequencing machines in the final assembly line with regard to the supply of parts has been investigated. For this reason, a basic integer linear programming model has been developed and based on this, the problem-solving algorithm is developed in accordance with the reaction-based approach based on the renewal of the sequence of operations. Also, due to the Np-hard...

the task of balancing of assembly lines is well-known in mass production system but this problem is np-hard even for the simple straight line. therefore, utilizing heuristic methods for these problems is totally unquestionable. furthermore, in line with balancing problems, heuristic methods are the foundation of the metaheuristic methods, thus it seems to be necessary to use more efficient heur...

introduction: work pressure and excessive workload can jeopardize and impair the people’s health. one of these impairments is musculoskeletal disorders. among these disorders, low back pain is the most common and most costly problem. the purpose of this study was to investigate the relationship between workload and prevalence of low back pain in assembly line workers of a car manufacturing fact...

In this paper, a mixed-model assembly system is modeled using ATPN (agent oriented timed Petri net) based on assembly resources classification. Firstly, the basic concepts and definition of ATPN is described. Secondly, with ATPN method introduced into mixed-model system research the modeling of a mixed-model assembly system is discussed. The development of an ATPN model for a MMAS consists of f...

Today’s buyer markets and lean supply chains require build-to-order assembly systems with just-in-sequence (JIS) deliveries. Simultaneously production systems have become prone to supply disturbances (i.e. events) that endanger the synchronized delivery of all JIS components to the assembly line. To uphold production sequence stability, rescheduling is frequently required. Current methods, howe...
