Multi-manned assembly line, which is broadly utilized to assemble high volume products such as automobiles and trucks, allows a group of workers different tasks simultaneously in multi-manned workstation. This additional characteristic parallel operators increases the complexity traditional NP-hard line balancing problem. Hence, this paper formulates Type-I problem minimize total number worksta...

The assembly of large and complex products such as cars, trucks, white goods typically involves a huge amount production resources workers, pieces equipment, layout areas. In this context, multi-manned workstations commonly characterize these lines. simultaneous operators’ activity in the same station suggests considering compatibility/incompatibility between different mounting positions, equip...

This paper proposed a parallel automated assembly line system to produce multiple products having multiple autonomous guided vehicles (AGVs). Several assembly lines are configured to produce multiple products in which the technologies of machines are shared among the assembly lines when required. The transportation between the stations in an assembly line (intra assembly line) and among station...

Proper planning of assembly lines is one of the production managers’ concerns at the tactical level so that it would be possible to use the machine capacity, reduce operating costs and deliver customer orders on time. The lack of an efficient method in balancing assembly line can create threatening problems for manufacturing organizations. The use of assembly line balancing methods cannot balan...

In this paper we are to present a practical application of Axiomatic Design (AD) methodology, as a roadmap to lean production, in redesigning a car body assembly line. Axiomatic Design theory provides a framework to simplify the whole problem. According to the AD principles, a hierarchical structure has been developed. The developed structure originated in lean manufacturing principles and exis...

In this era of product customization, the optimal usage of resources especially the available facilities and operators who are adding the value to the product is important. When the main production system needs to produce a large variety of products, the cost must be kept at minimum. Therefore the assembly line has to be planned in a much more flexible way. The present work deals with the optim...

Assembly lines are flow-oriented production systems that are of great importance in the industrial production of standard, high-volume products and even more recently, they have become commonplace in producing low-volume custom products. The main goal of designers of these lines is to increase the efficiency of the system and therefore, the assembly line balancing to achieve an optimal system i...

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...
