| Summary: | Facility Layout Problem (FLP) is a classical problem that widely exists in various fields. Recently, there is an increasing concern about energy saving for large-room buildings. This is because a large-room building can accommodate a large number of people at a time. Improper facility layout can affect the thermal environment, circulation of people, and energy consumption in the large room. Hence, there is a need to study FLP in a large room. However, this issue is either still lacking research evidence or often overlooked in the literature. The trend of recent studies in FLP is more inclined towards leverage optimisation or meta-heuristic approaches. Some optimisation approaches rely on the penalty function to solve FLP. It is argued that the constraints in the penalty function are usually being prioritised only by human judgement and intuition, and these could lead to bias and imprecise FLP objective function. Therefore, this research aims to identify the priority of FLP constraints in a large room using the Multi-Criteria Decision Making (MCDM) approach. The quantitative method of MCDM was developed in this study, and the results were based on the Decision-Maker's subjective opinion. Seven weighting methods were developed and validated using experimental procedures. The empirical result was compared and analysed. The Sum-Reciprocal (SR) technique highlighted the closest to the average value by 0.09%. The ability of the technique to produce the ranking with a small total weight difference (i.e. less than 10%) indicates the uniformity of the Decision Maker's assessment and is considered appropriate and sufficient. The approach and resulting yield of this study are anticipated to improve the decision-making of FLP formulation and contribute to better decision-making for FLP in library buildings. |
