The hybrid structural interaction matrix : A new prioritizing tool for maintenance

Purpose – The purpose of this paper is to present a new star in the continuous improvement research, the hybrid structural interaction matrix (HSIM). The work compares the results of this decision science methodology with that of analytical hierarchy process (AHP) with a case drawn from a published work in the maintenance performance literature. It further identifies certain areas of improvements for enrichment of this body of knowledge. Design/methodology/approach – The methodology presented in the work is termed the hybrid international matrix with potentials for prioritizing simple and complex numbers of maintenance activities or items. Findings – The results obtained indicate the feasibility of prioritizing items in maintenance with some improved results in the quality of decision made based on the prioritization. Research limitations/implications – The limitation of the study lies in the fact that a computerized system is needed when the items to be prioritized are many. Practical implications – Practically, it is noted that the quality of decisions made based on the methodology is enhanced. Thus, managers in practice would better achieve higher level of reliance than in the use of previous models that are similar. Originality/value – The paper is new. It presents a novel contribution, which is capable of being extended for the benefit of researchers or maintenance. The work presents some research opportunities with potentials of elevating maintenance productivity theory and practice into the ranks of major concepts in maintenance performance evaluation.
