Assembly line balancing is a classic ill-structured problem where total enumeration is infeasible and optimal solutions uncertain for industrial problems. A quantitative approach to classifying problem difficulty and solution quality is therefore important. Two existing measures of difficulty, Order Strength and West Ratio are compared to a new compound expression of difficulty, Project Index. ...

In industrialization, to be able make cheap and fast production, assembly lines are one of the most basic elements in serial production systems. It is important balance line continue smoothly. By balancing created, each work step grouped, stations created station time brought close cycle times. this study, a refrigerator top panel pressing analysed. The study’s aim for increase rate. Firstly, o...

Assembly line balancing has been a focus of interest to academics in operation management for the last decades. Despite diverse research works in this field, many problems still remained unsolved. Given the importance and attractiveness of the mixed product parallel lines balancing problem and the importance of the human factor in the development process and also very few studies in relation to...

In this paper, we present an extension to the TSALB problem (Time and Space constrained Assembly Line Balancing) with ergonomic risk restrictions. This ergonomic risk is defined from the task durations and their categories regarding to the risk factor for the workers. A study is presented through a case linked to an engine assembly line in the Automobile industry, considering variable demand.

In this article, we introduce two new variants of the assembly line worker assignment and balancing problem that allow parallelization of and collaboration between heterogeneous workers. These new line balancing approaches introduce an additional level of flexibility in the assignment and planning process, which may be particularly useful in practical situations where the aim is to progressivel...

Use of interpretative structural modeling (ISM) is inspired by the versatility displayed by this method, as reported by researchers, across a wide spectrum of economic and competitive complexities affecting businesses. The aim of this paper is to develop and analyze the relationship among the identified various functional /technical objectives (criteria's) of assembly line balancing proble...

The General Assembly Line Balancing Problem with Setups (GALBPS) was recently defined in the literature. It adds sequence-dependent setup time considerations to the classical Simple Assembly Line Balancing Problem (SALBP) as follows: whenever a task is assigned next to another at the same workstation, a setup time must be added to compute the global workstation time, thereby providing the task ...

Worker assignment is a new type of problem in assembly line balancing problems, which typically occurs in sheltered work centers for the disabled. However, only a few contributions consider worker assignment in a two-sided assembly line. This research presents three variants of artificial bee colony algorithm to solve worker assignment and line balancing in two-sided assembly lines. The utiliza...
