2111 Quantification of Knou-how and System Maintenance Organization Required for Maintenance of Know-how : Estimate of the number of the system maintenance engineers of the appropriate size

Abstract

In recent years, the intensification of the system trouble caused by the know-how lack of maintenance engineers becomes the social problem. It is necessary to reserve the minimum number of engineers having the know-how as system maintenance engineers to maintain the know-how in the organization. On the other hand, new business opportunity may be lost when there are too many maintenance engineers. Therefore, it is vital to build the maintenance system of the appropriate size. It is described the example that visualized the maintenance system of the appropriate size by trying quantification of the know-how that one engineer required maintain and manage.
