Search support device, search support method, and search support program

Abstract

This invention provides a search support device, a search support method, and a search support program that can assist in formulating an optimal search plan. [Solution] For each of the multiple sensor operation methods, the system includes an evaluation means that calculates a recommended movement path for the sensor based on the sensor position where the evaluation index value is maximized over time, and also calculates the total value of the evaluation index value up to a predetermined time, and an output means that outputs the recommended movement path and total value for each sensor operation method.
