Workload smoothing in simple assembly line balancing. Index terms assembly line, workstations, line balancing. Abstract assembly line balancing is to know how tasks are to be assigned to workstations, so. This paper considers heuristics which can be helpful in reducing a workstations number in assembly line balancing problem. The smaller balance delay means the less idle time idle an assembly line balancing. What is line balancing assigning each task to a work within an assembly line in order to meet the required production rate and to achieve a minimum amount of idle time. Assembly line balancing problem with reduced number of. Smoothness index stmax maximum station time in most cases cycle this is the index to indicate the relative time, smoothness of a given assembly line.
In this video various terminologies like balance delay, line efficiency, smoothness index etc. Improvement of garment assembly line efficiency using line. Our objective is to minimize the sum of the squared deviations of the workstation loads around the cycle time, hence maintain workload smoothing. The present study aimed at balancing the garment assembly line using the ranked positional weight technique to increase the line efficiency as well as minimize the number of workstations without viol.
Heuristic procedure for the assembly line balancing. Smoothness index this is the index to indicate the relative smoothness of a given assembly line balance. International journal of occupational safety and ergonomics. This is first of the 2 videos on assembly line balancing under the subject industrial engineering. This is the index to indicate the relative smoothness of a given assembly line balance. Line efficiency is the ratio of work stations time to the cycle time multiplied by the number of stations and smoothness index is an index that becomes the relative refining index of an assembly line balance.
Assembly lines are useful for mass production of standard as well as customized products. Findings minimizing the smoothness index is not necessarily equivalent to minimizing the nws. In the last sixty years a large variety of heuristics and exact solution procedures have been proposed to balance different structures of assembly lines. Pdf assembly line balancing is the problem of assigning. Pdf line balancing techniques for productivity improvement. Using the taguchi method to optimize the differential evolution algorithm parameters for minimizing the workload smoothness index in simple assembly line balancing. Landasan teori line balancing menurut gaspersz 2004, line balancing merupakan penyeimbangan penugasan elemenelemen tugas dari suatu assembly line ke work stations untuk meminimumkan banyaknya work station dan meminimumkan total harga idle time pada semua stasiun untuk tingkat output tertentu.
