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...

In this paper, a multi-station assembly process is modeled for diagnosing automotive body dimensional faults. The proposed approach enables multi-station assembly process modeling based on design information (CAD) and allows system behavior determination based on the in-line measurements of the final product. The method includes generic modeling of the key assembly process characteristics; tool...

assembly lines are special kinds of production systems which are of great importance in the industrial production of high quantity commodities. in many practical manufacturing systems, configuration of assembly lines is fixed and designing a new line may be incurred huge amount of costs and thereby it is not desirable for practitioners. when some changes related to market demand occur, it is wo...

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...

This study presents a reduction of production disturbances of a shoemaking industry through discrete event simulation approach. The study is conducted at Peacock Shoe factory found in Addis Ababa, Ethiopia.  This factory faces line balancing problem that becomes production disturbance for its assembly lines. Detail time study is carried out for the selected shoe model using stopwatch. Assembly ...

Abstract With the increasingly fierce competition in automotive industry, requirements for automobile wheel hub assembly line weregetting higher and higher, matching machine has become an indispensable part of line. In this paper, structure pneumatic drive servo was adopted by tire machine, which ensured production rhythm accuracy requirements. According to overall index automatic machine,the s...

There are an innumerable number of precision automotive assemblies which use pinned joints for alignment. Many of these suffer from poor performance and cost/quality issues because pinned joints are inherently over-constrained. This paper introduces the Quasi-Kinematic Coupling (QKC) as a solution for precision (better than 10 microns) automotive assemblies. For these applications, QKCs require...
