Review Of Attractors-Repeller Approach For Facility Layout Design (Case study at PT. Solo Grafika Utama)

Abstract

Facility layout is important factor to be considered because of its big and long term effect toward production cost incurred. This research analyzes performance of Attractors-Repeller approach for facility layout design. Attractors-Repeller approach is development of Non-Linear optimization Layout Technique which contributes to simplify phase one and two of Non-Linear optimization Layout Technique in single mathematical model. This simplification expected to provide better initial starting point for phase three so that it can be solved efficiently using suitable optimization algorithm. The objective of this research is to explore the behavior of Attractor Repeller approach for facility layout design and find the factor which determines that behavior. Case study in PT. Solo Grafika Utama gives a condition in where, from fifteen departments included, only seven departments that are able to move. In this case study, Attractors-Repeller approach succeeds to provide improvement only when overlap occurs. There is a trend in where material handling cost improvement leads to increase the number of overlap. Overlap occurs because assumption of target distance when value of α reduced is smaller.
