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...

ABSTRACT: Multi-manned assembly lines are widely used in manufacturing industries that process a high-volume of large-sized workpieces. At each workstation there multiple workers simultaneously performing different tasks with the possibility interfering other, leading to an increase processing task times. This paper studies this type problem: multi-manned line balancing problem dependent times ...

Assembly line balancing problems (ALBP) arise whenever an assembly line is configured, redesigned or adjusted. An ALBP consists of distributing the total workload for manufacturing any unit of the products to be assembled among the work stations along the line subject to a strict or average cycle time. Traditionally, stations are considered to be manned by one operator, respectively, or duplica...

background; work-related musculoskeletal disorders (wmsds) may involve all parts of the body, and have been a worldwide problem. employed women are two to five times more likely to report such problems, and assembly lines suspected to induce more wmsds because of high rate of repetitive motions. methods;the aim of this study to determine the prevalence of wmsds in women workers of an automobile...

with the growth in customers’ demand diversification, mixed-model u-lines (mmul) have acquired increasing importance in the area of assembly systems. there are generally two different approaches in the literature for balancing such systems. some researchers believe that since the types of models can be very diverse, a balancing approach without simultaneously sequencing of models will not yield...

Product customization and frequent market changes force manufacturing companies to employ mixed-model instead of simple assembly lines. To well adjust the line’s capacity production requirements, line can benefit from concept reconfigurability. Our study deals with a reconfigurable where tasks be dynamically assigned stations at each takt, workers move among end order entering product models is...

This paper presents a multi-objective Particle Swarm Optimization (PSO) algorithm for worker assignment and mixed-model assembly line balancing problem when task times depend on the worker’s skill level. The objectives of this model are minimization of the number of stations (equivalent to the maximization of the weighted line efficiency), minimization of the weighted smoothness index and minim...
