PIPE LINE RENEWAL PLANNING SUPPORT SYSTEM AND PIPE LINE RENEWAL PLANNING SUPPORT METHOD

摘要

PROBLEM TO BE SOLVED: To support planning of an optimum pipe line renewal plan minimizing life cycle cost of a pipe line.SOLUTION: A pipe line renewal planning support system 100 includes: a storage device 101 storing cost-calculating information 125 including attribute information about a pipe line; and an arithmetic device 104 calculating renewal introduction cost required for water pipe line renewal and maintenance management cost of a water pipe occurring according to water leakage in the water pipe, on the basis of the cost-calculating information, calculating life cycle cost of the water pipe from the calculated renewal introduction cost and maintenance management cost, calculating optimum water pipe line renewal time minimizing the calculated life cycle cost, and displaying each information of the calculated renewal introduction cost, maintenance management cost, life cycle cost, and optimum water pipe line renewal time on an output device 106.
