摘要

Abstract

Interpretative structuralmodel (ISM) can transformamultivariate probleminto several sub-variable problems to analyze a complex industrial structure in a more efficient way by building a multi-level hierarchical structure model. To build an ISM of a production system

the partial correlation coefficient method is proposed to obtain the adjacency matrix

which can be transformed to ISM. According to estimation of correlation coefficient

the result can give actual variable correlations and eliminate effects of intermediate variables. Furthermore

this paper proposes an effective approach using ISMto analyze themain factors and basic mechanisms that affect the energy consumption in an ethylene production system. The case study shows that the proposed energy consumption analysis method is valid and efficient in improvement of energy efficiency in ethylene production.
