“…As shown, 65 trouser assembly line tasks were assigned in 39 workstations with total workstations time of 41.763 minutes and total idle time of 33.117 minutes. The idle time for workstations number 5,6,8,10,19,21,24,26,27,28,29,33,34,36,37,38, and 39 remained very high because of the restrictions on the resource (machine type and helpers) and the precedence relations. The precedence diagram illustrating the relations between 65 tasks in 39 workstations was presented as shown in Figure 5.…”

“…This is because heuristic technique provides a simple and better way to plan the sewing lines within a reasonable time than other line balancing techniques. 25,26 Despite it being an old line balancing technique, very few garment manufacturing industries have comprehended heuristic method due to inadequacy of information and literature on its practical applications. 23 In this study, deterministic task time has been assumed in garment assembly line balancing with the simplest heuristic technique known as ranked positional weight.…”

The current competitiveness of garment manufacturing industries is highly dependent on ability to improve efficiency and effectiveness of resource utilization through proper application of industrial engineering techniques such as line balancing and time study. However, very few apparel industries have comprehended industrial engineering function due to little knowledge on practical application of industrial engineering techniques. The present study aimed at balancing a trouser assembly line using the ranked positional weight technique to increase the line efficiency as well as minimize the number of workstations without violating the constraints: precedence relations, cycle time, and resource type. The empirical study was conducted at Southern Range Nyanza Limited (NYTIL) garment manufacturing facility to demonstrate the practical application of ranked positional weight line balancing technique. Results showed that ranked positional weight method is suitable only for assembly line balancing with no constraint on the resource. However, most complex garment assembly lines consist of a number of different machine types rendering ranked positional weight method practically ineffective for improving line efficiency of a complex garment assembly line. Therefore, profound line balancing using simulation-based optimization to improve the line efficiency of complex garment assembly line should be investigated.

“…The problem dealt with here is a Mixed-model ALBP (MALBP), with extra complexities. Scholl & Becker (2006), Tasan & Tunali (2008), Chen et al (2012) refer to this type of problems and illustrate various objectives such as, minimising the number of workstations, reducing the cycle time, maximising the line efficiency and finding a feasible solution.…”

Portuguese footwear industry has improved dramatically to become one of the main world players. This work is part of a project in cooperation with a large footwear company, operating a new automated assembly equipment, integrating various lines. Balancing such lines implies going from an almost manual preparation executed by experienced operators, to a planning supported by optimisation systems. These complex mixed-model lines have distinctive characteristics, which make balancing a unique problem. The paper proposes the ASBsm-Assembly System Balancing Solution Method, a new method that integrates a constructive heuristic and an improvement heuristic, which takes inspiration from Tabu Search. The solutions obtained, based on real instances, are quite encouraging when compared with other effected factory solutions. Consequently, the balances obtained by ASBsm are now being implemented and articulated with sequencing methods.

“…At the end of the application of bee algorithm, they were able to minimize the number of work stations and the given cycle time. Chen, et al [16] applied assembly line balancing in garment industry. A group genetic algorithm (GGA) was developed for assembly line balancing problem of sewing lines with different labour skill levels.…”

The application of fuzzy logic in balancing a single model tricycle assembly line is presented in this study. MATLAB simulation software was used in the analysis of the primary and secondary data obtained from the assembly line under study. Results obtained from the study show that the efficiency of the line increased from 88.1% to 92.4%. The total idle time was also reduced by 56.5%. This indicates an improvement in the efficiency of the line, reduction of bottleneck, and even distribution of tasks along the line for the company under study.
