碩士 / 東吳大學 / 企業管理學系 / 100 / Tractor operational efficiency is the key for a freight transportation company to fulfill its customer demand and enhance its profitability. That is, it is crucial to develop a comprehensive analytical framework to effectively evaluate the tractor operational efficiency and to suggest improvement directions. However, the tractor operational efficiency assessment involves complex multiple inputs and outputs, each of which can hardly represent the efficiency of a given tractor. Therefore, this study aims to utilize Data Envelopment Analysis (DEA) modeling method to evaluate the tractor operational efficiencies using multiple inputs (fuel consumption, maintenance & repair expenses, driver salaries, and empty kilometers) and outputs (loads, revenue, load kilometers, and days of transport assignment). This study follows action research method and work closely with F freight transport firm to extract its domain knowledge on the tractor operations and investigate their managerial insights. The research findings show that maintenance & repair expenses, empty kilometers, and loads are main factors to the low operational efficiencies. Management should follow up and clarify root causes based on the poor performing input and output factors. Last but not the least, F company should design a better system for the tractor operational efficiency management to motivate the tractor efficiency improvement and bring up overall company-wise and fleet-wise operating performance.
