Abstract


Objectives: This paper focuses on the influence of delay time parameters on the consequence parameter of downtime per unit time. Methods/Analysis: DTA data sets needed for various systems are synthesized in line with the Taguchi method of design of experiments. Main effects of plot for the parameters are arrived for individual parameters. Interaction effect among parameters also had been considered for analysis. Findings: Main effects of plot for means clearly reveals the parameters having most influence on the consequence variable of downtime per unit time. Also the inspection time is found not influence much. Attempt also has been made in this article to find out the interaction between certain key parameters. The interaction plot reveals the clear opposite interaction between some parameters and the maintenance inspection time. Application/Improvements: The information on the factors that affect the down time the most can best be utilized by maintenance managers and other stake holders to give focused attention to particular parameters associated in breakdown failure reduction techniques, during the post-DTA implementation period.

Keywords
