To facilitate installation of vibration sensors for detecting leakage of a fluid flowing in a duct network, in an appropriate arrangement in the duct network.SOLUTION: A vibration sensor installation support system is configured to calculate an arrangement in a duct network, of vibration sensors that are installed in the duct network and configured to detect leakage of fluid in the duct network which includes a plurality of connected duct elements and in which the liquid flows. The vibration sensor installation support system includes an installation position calculation part which, using inputted information on the duct network and inputted information on the vibration sensors to be installed, generates an expression of an optimization problem aiming at representing minimization of the total number of vibration sensors installed in the duct network while setting the number of vibration sensors capable of detecting the leakage of the fluid to be equal to or larger than a minimum number that is set for each duct element, and then calculates and outputs optimum installation position information on the vibration sensors to be installed by solving the expression of the optimization problem.SELECTED DRAWING: Figure 1 【課題】管路網を流れる流体の漏洩を検知する振動センサを、適切な配置で管路網に設置することを容易にすること。【解決手段】接続された複数の管路要素を有し内部に流体が流れる管路網に設置され、管路網での流体の漏洩を検知する振動センサの管路網内の配置を算出する振動センサ設置支援システムであって、管路網の情報と、設置する振動センサの情報を入力として、流体の漏洩を検知できる振動センサの数を、管路要素毎に設定する最小数以上にしつつ、管路網に設置する振動センサの全数を最小にすることを表す目的とした最適化問題の式を生成し、最適化問題の式を解いて得られる、設置する振動センサの最適設置位置情報を算出して出力する設置位置算出部を有する。【選択図】図１
