This report presents the results of a research effort to explore the use of computer simulation as a quantitative tool for planning, analyzing and evaluating Information Retrieval systems. A general time-flow model has been developed that enables a systems engineer to simulate the interactions among personnel, equipment and data at each step in an information processing effort. The input parameters for the simulation reflect the configuration of the system, the processing load of the system, the work schedule of the system, the work schedule of the personnel, equipment availability, the likelihood and effect of errors in processing and the location and availability of the system user. Simulation output provides a study of system response time both delay time and processing time, equipment and personnel work and idle time and the location and size of data queues. Included within this report is a discussion of the simulation rationale, the modeling methodology employed and the input and output data of the computer simulation programs. Additionally, one example of a system simulation is presented as an illustration of the capability of this kind of tool in systems analysis.
