BRIDGE MANAGEMENT AND ITS ACCOUNTING SYSTEMS


Abstract eng:
Concerning bridge management, to judge its adequacy through the comparison of LCC and to carry out the management according to a scenario has become a common practice among the national and local governments. However, despite that business appraisal from the cost-convenience point of view is becoming common nowadays for road services, there is almost no case of bridge construction or management in which convenience was taken into account. In addition, fundamental researches on the performance of such kind of appraisals are not yet advanced and whatever the reports, they have restricted themselves to mentioning the necessity of data accumulation. Thus, studies were carried out focusing on the following 2 items. 1. Introduction of cost-convenience to the bridge management and 2. The transition of Japanese public account principles from a cash based account to an occurrence based account. First, thoughts on cost-convenience were organized, and an attempt on optimization was carried out by performing a simulation based on genetic algorithm on a group of bridges of a certain area. In parallel, focusing on the public account, changes from the present cashbase method (It appropriates the annual income and the expenditure of the cash only as cost) to an accrued-base method, which is similar to that of private enterprises, were introduced. Comprehensiveness and integrity of the records were assured and flow as maintenance and repair costs and effectiveness of providing information of the stock as functional level of the facility were tried. The present paper presents a report on the results of the optimization simulation, considering convenience together with the results of a case in which deferred maintenance repair accounts were introduced into the maintenance of road pavement.
