Assembly line balancing problem with skilled and unskilled workers: The advantages of considering multi-manned workstations
This paper address a special class of generalized assembly line balancing in which it is assumed that there are two groups of workers: skilled and unskilled ones. The skilled workers are hired permanently while the unskilled ones can be hired temporarily in order to meet the seasonal demands. It is also assumed that more than one worker may be assigned to each workstation. To show the adv...
متن کاملBalancing assembly line with skilled and unskilled workers
In this paper, we present the process of rebalancing the line at motorcycle-assembly plant. The company found it necessary to rebalance its line, since it needs to increase production in the spring and summer months. The main characteristics of the problem are as follows: (i) the company hires temporary staff, who need more time to carry out their tasks than permanent workers; (ii) there must a...
متن کاملIntegrated Assembly Line Balancing with Skilled and Unskilled Workers
In this paper, we consider the problem of designing an integrated assembly line when many skilled and unskilled workers are available. This problem arises when there are certain limited resources available such as skilled workers in which the operation time for every task is different depending on assignment of the unskilled workers to help the skilled workers. The selection of both skilled wor...
متن کاملA Multi-Objective Particle Swarm Optimization for Mixed-Model Assembly Line Balancing with Different Skilled Workers
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...
متن کاملRobust assembly line balancing with heterogeneous workers
Assembly lines are manufacturing systems in which a product is assembled progressively in workstations by different workers or machines, each executing a subset of the needed assembly operations (or tasks). We consider the case in which task execution times are worker-dependent and uncertain, being expressed as intervals of possible values. Our goal is to find an assignment of tasks and workers...
