SYSTEM OPTIMIZATION WITH DIFFERING DEMANDS FOR SERVICE

For a given objective function which can be used for a system serving a single demand point, this paper defines a technique by which that objective function can be used to define an aggregate objective function for optimizing a system which is required to serve several different demand points. The objective function is defined for conditions under which demand is inelastic and all costs incurred by a group of users representing a single demand point must be paid by that group of users. The second condition is the same as the first, but with elastic demand. For the third condition, the problem of cross-subsidization among various users of the system is considered. The demand is considered to be elastic. Examples of the use of the technique for a commuter railroad are presented. In the examples, the objective function is the user cost where the cost includes fare, travel time, and the cost of inconvenience due to lack of service frequency.
