摘要

The aim of this paper is to analyze the reliability of a reach stacker in relation to its repair maintenance cost and time. The machine components were categorized into 3 systems and 14 subsystems. The Pareto method and Trend test were used for the analysis. The mechanical system has the most critical system with 46 failures representing 42%, and the hose has the most critical subsystem with 24 failures, which represents 22%. The value of the statistics is β=1.018, which indicates a negative growth since (β>1). The value of the Chi square (X_(2N)~2 = 216.11) is less than those of the critical values (CV1 = 186.67 and CV2 = 255.60), which led to the rejection of the null hypothesis of reliability growth at 10% significance level and the average total reliability of the machine is 0.984. As the reliability rises, the repair and maintenance cost and the time drop and as the reliability drops, the repair and maintenance cost increases and the time increases too.
