主　　题：Maintenance Performance DEMATEL Food processing Indicators 

摘      要：Purpose-Key performance indicators(KPIs)of maintenance systems serve as benchmarks to workers and organizations to compare their goals for decision-making purposes.Unfortunately,the effects of one KPI on the other are least known,restraining decisions on prioritization of KPIs.This article examines and prioritizes the KPIs of the maintenance system in a food processing industry using the novel Taguchi(T)scheme-decisionmaking trial and evaluation laboratory(DEMATEL)method,Taguchi-Pareto(TP)scheme-DEMATEL method and the DEMATEL method.Design/methodology/approach-The causal association of maintenance process parameters(frequency of failure,downtime,MTTR,MTBF,availability and MTTF)was studied.Besides,the optimized maintenance parameters were infused into the DEMATEL method that translates the optimized values into cause and effect responses and keeping in view the result of analysis.Data collection was done from a food processing plant in Nigeria.Findings-The results indicated that downtime and availability have the most causal effects on other criteria when DEMATEL and T-DEMATEL methods were respectively applied to the problem.Furthermore,the frequency of failure is mostly affected by other criteria in the key performance indication selection using the two methods.The combined Taguchi scheme and DEMATEL method is appropriate to optimize and establish the causal relationships of factors.Originality/value-Hardly any studies have reported the joint optimization and causal relationship of maintenance system parameters.However,the current study achieves this goal using the T-DEMATEL,TP-DEMATEL and DEMATEL methods for the first time.The applied methods effectively ease decisions on prioritization of KPIs for enhancement.
