On-Line System Availability and Service Simulation (OLSASS)

A methodology for establishing a generalized Monte Carlo model for system availability and service simulation is useful to perform on-line tradeoff analyses. An example of an on-line time-shared computer program for a model of an infrequently operating system covering a large number of operational applications is described in detail. Examples of implementing the model for a variety of situations are also included. Advantages of this program are the ready accessibility to the engineer of a variety of field support operation simulations and their resultant availabilities and logistics requirements. Through tradeoff of system design parameters and operational variables, the simulation provides the capability for rapid system optimization at low computer cost.
