A Multi-Objective Genetic Algorithm for Solving Assembly Line Balancing Problem

Abstract: In this paper, a multi-objective genetic agorithm to solve assembly line balancing problems is proposed. The performance criteria considered are the number of workstations, the line efficiency, the smoothness index before trade and transfer, and the smoothness index after trade and transfer. The developed genetic algorithm is compared with six popular heuristic algorithms, namely, ranked positional weight, Kilbridge and Wester, Moodie and Young, Hoffmann precedence matrix, immediate update first fit, and rank and assign heuristic methods. For comparative evaluation, 20 networks are collected from open literature, and are used with five different cycle times. All the six heuristics and the genetic algorithm are coded in C++ language. It is found that the proposed genetic algorithm performs better in all the performance measures than the heuristics. However, the execution time for the GA is longer, because the GA searches for global optimal solutions with more iterations.

Literature review on the agile manufacturing criteria

Abstract: Purpose – To review on the literature and contribute a comprehensive model that would identify the criteria for attaining agility and suggest a procedure to successfully implement it in manufacturing arena.Design/methodology/approach – The literature dealing with agile manufacturing (AM) criteria were studied. The meaning and definitions of AM were derived. Further, the criteria enunciated in certain papers were identified. These findings were used to design a 20 criteria agile model. Subsequently, its implementation procedure was designed.Findings – While reviewing the literature, the following observations were made: time and again, some researchers brought out certain criteria of AM; these criteria do not comprehensively focus towards attaining agility; the researchers who have contributed these criteria have failed to evolve an implementation procedure.Research limitations/implications – Contributions of this paper are based on reviewing the literature. Since, no survey in manufacturing arena has been...
