1. An administration planning system for preparing an administration plan for operating and maintaining a facility producing goods or services, using a computer, the administration planning system comprising:
- an inputting function inputting a planning term and plural investment items operating in a facility producing goods or services, and inputting investment levels, related to inspection and maintenance of each of the investment items, for each of the investment items for the planning term;
a risk calculating function calculating failure risk levels for each of the investment items based on a correlation between the investment level for each of the investment items and a failure risk percentage corresponding to the investment level;
an optimizing function preparing the administration plan, the administration plan including optimized investment levels and optimized failure risk levels by optimizing and adjusting distributions of the investment levels of the investment items and of the failure risk levels calculated by the failure risk calculating function for the planning term, wherein the optimizing function repeats, n times, an optimizing step includingcalculating neighborhood solutions for an initial solution set by a first optimum solution to minimize the sum of total investment of the investment levels and total failure risk of the failure risk levels, andselecting a second optimum solution from a group comprising the initial solution and the neighborhood solutions to minimize the sum of the total investment and the total failure risk, wherein the optimizing function prepares the administration plan, based on the second optimum solution selected in the nth repetition of the optimizing step; and
an outputting function outputting the optimized investment level and the optimized failure risk level for each of the investment items based on the administration plan prepared by the optimizing function.

Abstract
A system for preparing an administration plan using a computer, includes an inputting function, a risk calculating function, an optimizing function, and an outputting function. The optimizing function prepares the administration plan by optimizing and adjusting distribution between investment levels in investment items and the risk levels for a planning term.
