Under deterministic service capacity of an infrastructure system,its service level is dependent on its size of service area.The service area can be measured by its radius.By using the concept and method of value engineering,and taking the temporal satisfactory into account,a model is developed to describe the relationship between the cost and service radius for infrastructure system.With this model,optimal service radius can be determined by making trade-off between service capacity and public service demands.A case problem is presented to show the application of the proposed method.
