The mixed work assignment technique was applied to the modular production concept solve apparel assembly line balancing problem. Specifically, an algorithm implemented generate workstations by first classifying tasks into modules through analysis of manufacturing process and assigning grouped in single task–multiple workers multiple tasks–single worker methods. Then, sequentially performed cons...

Assembly line balancing problems consist in partitioning the work necessary to assemble a number of products among di erent stations of an assembly line. We present a hybrid approach for solving such problems, which combines constraint programming and integer programming.

We propose a stronger formulation of the precedence constraints and the station limits for the simple assembly line balancing problem. The linear relaxation of the improved integer program theoretically dominates all previous formulations using impulse variables, and produces solutions of significantly better quality in practice. The improved formulation can be used to strengthen related proble...

Assembly lines are typical flow oriented production systems, which are of great importance in the industrial production of high quantity standardized commodities. The assembly line balancing (ALB) problems deal with the assignment of various tasks to an ordered sequence of workstations, while optimizing one or more objectives without violating restrictions imposed on the line. In this study, we...

In this paper a process-oriented simulator for assembly lines is presented. The simulator considers mixed model lines, with stochastic task times, the possibility to have parallel stations, and to consider different scheduling sequences. The simulator is a flexible supporting tool in finding solution of the assembly line balancing problem (and the optimal sequencing problem associated to it) an...

Assembly line balancing is the problem of assigning tasks to workstations by optimizing a performance measure while satisfying precedence relations between tasks and cycle time restrictions. Many exact, heuristic and metaheuristic approaches have been proposed for solving simple straight and U-shaped assembly line balancing problems. In this study, a quite new optimization algorithm, Bacterial ...

This research addresses the mixed-model assembly line (MMAL) by considering various constraints. In MMALs, several types of products which their similarity is so high are made on an assembly line. As a consequence, it is possible to assemble and make several types of products simultaneously without spending any additional time. The proposed multi-objective model considers the balancing and sequ...

Recently Indonesian textile and garment manufacturer has experienced a problem with shop floor production. The complexities in the manufacturing process led to many problems such as inefficiency, thus prevented company from achieving its target. In fact, even though established efficiency target of 80%, production cannot realize it. Thus, this research aims increase line reach company’s At begi...

Assembly line balancing concerns the design of assembly lines for the manufacturing of products. In this paper we consider the time and space constrained simple assembly line balancing problem with the objective of minimizing the number of necessary work stations. This problem is denoted by TSALBP-1 in the literature. For tackling this problem we propose a Beam-ACO approach, which is an algorit...
