“…The assembly line balancing was proposed for the first time already in 1961 (Helgeson, 1961). Since then, many authors presented different approaches and case studies in the balancing of the production lines (Becker and Scholl, 2006;Boysen et al, 2007Boysen et al, , 2008Hamzadayi and Yildiz, 2012;Rabbani et al, 2012;Battaïa and Dolgui, 2013;Ghutukade and Sawant, 2013;Gurevsky et al, 2013;Kumar and Mahto, 2013;Hakami et al, 2014;Hu et al, 2014;Sane et al, 2014).…”

In this paper we present the case study for the optimization of the production line by using the balancing and discrete event simulation approach. First the basic theory and steps for the production line balancing are presented. For the real production process, consisting of two production lines and an assembly workplace the simulation model is built and the initial results obtained. After balancing of the production process and improvement of its performance some further steps of the process optimization by using the improved simulation model are performed. The results of the combination of the line balancing and further process optimization raise the production rate of the process enormously, which is obvious from the research results of this paper.

“…For illustrating the solution construction process, consider the priority permutation (5,12,3,10,9,1,6,2,7,11,4,8) for the problem instance with cycle time 10, max = 3, and precedence diagram given in Figure 1. All three target values are considered zero.…”

“…Assembly lines are mostly installed for producing products in high volumes and usually include automatic material handling system [1], tools, workers, and more than one workpiece. Therefore, in fact, assembly lines are designed by arranging all of their components.…”

In a multi-manned assembly line, tasks of the same workpiece can be executed simultaneously by different workers working in the same station. This line has significant advantages over a simple assembly line such as shorter line length, less work-in-process, smaller installation space, and less product flow time. In many realistic line balancing situations, there are usually more than one objective conflicting with each other. This paper presents a preemptive goal programming model and some heuristic methods based on variable neighborhood search approach for multi-objective assembly line balancing problems with multi-manned stations. Three different objectives are considered, minimizing the total number of multi-manned stations as the primary objective, minimizing the total number of workers as the secondary objective, and smoothing the number of workers at stations as the tertiary objective. A set of test instances taken from the literature is solved to compare the performance of all methods, and results are presented.

“…They solved this robust model with a breadth-first search procedure. This academic work explored the minimal number of workstations for the straight assembly lines when the proportion of all pessimistic tasks in a workstation was varied [21]. Hazır and Dolgui indicated the straight assembly line for the interval task time which was a type-2 problem.…”

UL (U-shaped Line) reduces the waste material in a manufacturing process. This paper presents the application of three U-shaped Lines with the minimum workstations which consists of UL-1, UL-2, and UL-3. The uncertain task of three U-shaped Lines determines the time as an interval. Three U-shaped Lines formulate the model with a binary integer linear programming. Each uncertain task reduces the normal time to the optimism time. The normal time reduction relates to the allowable time inversely. This paper indicates the procedure of the normal time reduction that applies MATLAB R2014a. The allowable time of UL-1, UL-2, and UL-3 for each uncertain task is 1.5 times of the optimistic time, 1.2 times of the optimistic time, and 1 time of the most optimistic time, respectively. For the utility of this paper, the uncertain task adjusts the finish time which does not affect the modification of the minimum number of workstations.
