EVALUATION OF BUS MAINTENANCE PROCEDURES THROUGH SYSTEMS ANALYSIS: A CASE STUDY

Every transit company is faced with the maintenance operations of buses. Each bus in the garage is a loss of revenue. In order for the transit system to operate efficiently, maintenance procedures must be such that buses receive proper maintenance and repairs with minimum loss of time. The main purpose of this study is to provide an analytical basis for a bus maintenance shop. Bus maintenance procedure is primarily based on the mileage of the buses and the life mileages of major parts on each bus. This procedure becomes complicated as the variety of bus types increases as well as when number of parts grows. To make formal analysis possible a generalized model was constructed. This model consisted of submodels of the inspection shop, the repair shop and a cost minimization submodel. The validity of the models was established through comparison between observed data and that produced by the model. Information made available by the Denver Metro Transit Company (DMT), which is owned and operated by the City and County of Denver, was used as the observed data base. Queueing theory plays a key role in the analysis of the inspection shop and repair shop. The relationship among the various factors was examined and it was found that most of the characteristics of each part were determined by curve fitting to the life mileage curve, which can be determined by curve fitting to the actual data. The model, according to the authors, provides much insight into a maintenance shop. Figures, tables and references are furnished.
