地震時における中小企業の被害予測に関する研究

Abstract

The purpose of this paper is to construct a disaster prevention diagnostic system for small and medium-sized companies, with an emphasis on management-related damage in large earthquakes. A lot of companies which were damaged in the Niigata-ken Chuetsu Earthquake were investigated with regard to the immediate amount of damage to buildings, building equipment and production facilities, as well as the amount of indirect damage to sales. The main results are summarized as follows; 1) Companies which were damaged immediately, accounted for 90 percent of the whole. Looking at the breakdown we can see that there was 80 percent damage in the building, 40 percent in the production facility. 2) Immediate damage and capital, the level of building destruction, building equipment, production facility, goods in process, have a correlation. 3) Indirect damages such as sales and delivery delay, and the amount of destruction of factories and land, have a correlation. 4）Based on the above results, the amounts of direct harm and indirect damage can be easily estimated by factoring the capital of the company and the number of employees.
