This thesis aims to study the relationship between diesel prices and factors that affecting the total cost of truck transportation in order to develop a model explaining the relationship between total cost of truck transportation and changes in diesel prices. This model obtains the information regarding the operating and administrative expenses from a case study of the 10-wheels truck transport operator. This model comprises of four main stages including data collection, analysis of the relationship between each cost factor of truck transportation and change in diesel prices, development of regression analysis to forecast each cost factor of truck transportation under certain diesel price, and structure a model by adopting the results of regression analysis and the equation of total cost of truck transportation. From this analysis, there is a strong correlation between change in diesel price and cost of truck transportation including tire price, lubricant price, minimum wage, and repair and maintenance expenses including spare parts and supplies. The model reveals the magnitude of changes in each cost factor for each unit change in diesel price, and allows the transport operator to properly estimate the total operating cost under the volatile diesel price circumstance and enable to use it as secondary data for further management decision making.
