A MULTI-MODAL GOODS DISTRIBUTION MODEL WITH EMPHASIS ON AIR CARGO

An examination is made of the role in Canada's economic development of its domestic air cargo transport industry in conjunction with its two major competitors, road and rail, over a time frame of 1967 to 1987. A macro model, forecasting the ton-mile freight demand for road, rail and air services is developed. It relates ton-miles to the growth in gross national product. A brief study is made of expected technological developments in each mode, with particular emphasis on the air cargo mode, as they affect future transportation costs. Cost data are collected for each mode for the base year 1967. Based on this information, component cost data are developed for later use in the distribution model. A model employing linear graph analysis techniques is developed to simulate the three-mode transport industry. It is demonstrated on a three-mode two-mode hypothetical system. A 30-city, three-mode model of the nation's goods distribution system is then calibrated on destination distribution. In its present state it is a pilot model.
