A computer model and SIMSCRIPT program, applied to the USAF internal air cargo network, LOGAIR. Using the AFLC daily cargo forecast as a demand table, the route generator determines all possible routes that meet the constraints. Then the allocation model, a linear programming formulation, chooses the best in each case and reports all information. An IBM 7044 computer run of two to five minutes gives a complete evaluation for up to 800 source-destination pairs for one of four optional linear programs. The output can be used by systems designers as a basis for inputting proposed improvements and iterating toward better systems. Complete program documentation is appended.
