An Aggregator Preprocessor for NAVMOD

Abstract : This paper documents an aggregator preprocessor computer program that has been developed to facilitate certain aspects of data generation for the NAVMOD naval model. NAVMOD simulates only a limited number of types of different naval resources; input data for NAVMOD combat must be expressed in terms of these types. The aggregator preprocessor reads data for actual types of naval weapons or other resources. Using a weighted averaging technique, the computer program computes aggregated data values suitable for use by NAVMOD and outputs them in a format that NAVMOD can read. The weights used in the averaging procedure are based on user inputs. This allows the user to specify the relative compositions of the NAVMOD resource types in terms of actual types of naval resources. The program develops aggregated resource effectiveness values that are consistent with these relative compositions. The program makes extensive use of the INGRES database management system; it is written in FORTRAN with embedded INGRES database commands. It is designed to run on a Digital Equipment Corporation VAX computer with the VMS operating system, but it probably can be converted to run on some other machines.
