- Abstract
- The rapid increase in energy consumption of manufacturing industries accelerates the development of metrics for measuring manufacturing facility energy efficiency. In response to this demand, various metrics such as cost, delivery, energy efficiency, quality, flexibility, etc. for measuring the efficiency of manufacturing facility are under development. However, since multiple efficiency metrics are under development, it becomes necessary to develop simple and effective method for assessing manufacturing facility energy efficiency by using multiple metrics. Currently, spider web chart and control chart that extends the capability of spider web chart are commonly used in various industries in order to effectively analyze the efficiency. The spider web chart and control chart method provide an easy comparison of holistic energy efficiency among multiple manufacturing facility or temporal trend. But, it is known that those methods have limitations such as equal weights on metrics and no overall evaluation. In order to resolve the limitations, we propose a weighted spider web chart model. The main objective of this paper is to present the general weighted spider web chart model and investigate the usefulness and applicability of the proposed weighted spider web chart model through the strength-weakness-opportunity-threat (SWOT) analysis.
