<p>[Problem] To minimize investment and operation costs through an entire design period extending over two or more years in designing the facility of a water distribution system. [Solution] A facility design system (100) is configured from: a storage device for holding at least data relating to constituent elements of a water distribution facility, and data relating to constraints on water distribution facility design; and an arithmetic-logic unit for executing a process for generating, on the basis of data relating to a water supply source, a customer facility, and a water distribution means included in the constituent element-related data, a pattern of a water distribution network linking between each of the water supply sources and customer facilities with the water distribution means, and a process for specifying, as facility design data, a water distribution network for which a total cost is minimum for each fiscal year from among the patterns of water distribution network, and storing the facility design data for an entire design period in the storage device, the specification being made on the basis of data on costs required for the introduction and operation of a prescribed constituent element included in the constituent element-related data, and data on a design period included in the constraint-related data, and on condition that a prescribed constraint included in the constraint-related data be satisfied between each fiscal year of a design period.</p> |
