Abstract : Research is directed to formulating a bridge and resource requirements simulation model for use by program managers concerned with the ground lines-of-communication sector of the construction industry. Bridge alternatives are designed and selected to reduce the obstacle effect of the terrain such that commodities flow (traffic) along the line-of-communication (highway) is improved. The resulting tool provides a heuristic high-resolution model for policy testing and decision making in a highly dynamic system involving non-commensurable objectives such as cost, time and manpower. The problem of predicting bridge and resource requirements is defined through a systematic analysis of the bridge construction system's purpose, components, constraints and required information. Examples of the need for accurate prediction of requirements are discussed for both the civilian and military applications. (Modified author abstract)
