This paper presents a procedure for calculating system and component utilization patterns or load curves which describe the use of a single service facility by several independent agencies. Such load curves are frequently used to allocate cost of the facility among the agencies it serves. The procedure is a computer model that establishes a link between data that are readily obtain ed and data that are required by allocation formulas. The model derives detailed load curves for each agency and for the-total system. A Monte Carlo procedure is suggested in which the model may be used to estimate the sensitivity of allocation formulas to error in the underlying data.
