Dynamics of intermaterial competition in the automotive industry. Part I. A framework for analysing the dynamics of intermaterial competition
Increased consumer interest in vehicle fuel economy was initially sparked by the 1973 to 1974 OPEC oil embargo and the subsequent domestic fuel shortage that resulted in rapidly increasing fuel prices. This initial consumer interest became a federal mandate with the establishment of a national fuel economy standard of 27.5 miles/gallon by 1985. More recently, the OPEC price escalations of 1979 to 1980 have resulted in even greater demand for fuel-efficient vehicles. A dynamic simulation model of intermaterial competition is presented, with special reference to the automotive industry. The structure of the model consists of three major components: (1) the demand for structural materials, (2) the production capacity and the availability of materials, and (3) the market split for competing materials. It is expected that the simulation model will be useful for analyzing the substitution dynamics and the associated demand for either two substitute materials in a specific fabricated form in a particular end use or, more generally, for all substitute materials in any form for all applications within a specific end-use sector. 4 figures.
