Facility Layout Improvement Using Systematic Layout Planning and Multi-Criteria Decision Making: A Case Study in the Electronics Industry

Abstract

This research aims to improve the factory layout to accommodate the addition of two new production lines for printed circuit board assembly (PCBA). An initial assessment identified that the existing layout could not effectively support expansion due to inadequate workspace and disrupted process flow in Production Line, resulting in excessive material handling and reduced production efficiency. To address these issues, three layout alternatives were designed using Systematic Layout Planning (SLP) and evaluated with Analytic Hierarchy Process (AHP) based on material distance, safety, flexibility, and space utilization. Alternative 3 was selected as optimal, reducing material–handling distance by 40%.
