Decision Support System for

Search And Rescue of Missing People

SHARON is an international research project
organized and promoted by


SearcH And Rescue Operation assistaNt

SHARON is devoted to the Search and Rescue mission management, it provides advices on how to deal with the various phases of the mission, starting from the collection of the target's informations and supporting the decision maker until completion of the research.

Target Data Collection

Simple online interface for entering personal data of the missing person.

Target Presence Probability Maps

Estimate the Target's presence probability on the basis of prediction models and best practices adopted worldwide.

Search Area Estimation

Estimates the paths and the maximum area reached by the Target in given time. Person profile and environment characteristics are exploited.

Search Units Planning

Suggest tradeoff solutions for allocating Search Units and routing men from their real-time location to the base camp.


Provides a web-based interface and intuitive wizards for filling Target information, configuring the mission and viewing results in 3D world map.


It offers a complete report of the Mission, with prints dedicated to the various single phases and a simple interface for sharing information.


Where could be the Target?

Estimate Target's Presence Probability accordingly to:
Known Positions

e.g., Last Seen Position

Terrain Features

e.g., Elevation, Roads

Presence Probability Map

The target was last seen at Gardeccia refuge (RED Marker) and it is known that his destination (BLUE Marker) was Passo Principe.

SHARON estimates the probability of presence in the nearby area accordingly to best-practices. The combined result is shown on interactive 3D map: cold colors indicate a low probability, hot colors indicate an higher probability.

How could the Target move?

Estimate the fastest paths (worst case) from Last Seen Position and accordingly to:
Person Profile Information

e.g., age, physical condition, interests, ..

Terrain Characteristics

e.g., morphology, vegetation, roads, ..

Estimated Target's Paths

SHARON simulates fastest paths in the nearby area starting from the target's last seen position at Gardeccia refuge (RED Marker).

As expected accordingly to the example scenario morphology, the Target should move on tracks around the mountain peak.

How far can be the Target?

Estimate the maximum distance reached by the Target since Last Seen Position and Time, accordingly to:
Fastest Paths Simulation

intra-cell velocity and time estimation

Full Grid Exploration

inter-cell navigation policies

Estimated Travel Time

The Target is assumed to move from Last Seen Position at Gardeccia refuge (RED Marker) in nearby area.

The time required to reach each cell of the grid (and its fastest path from LSP) is estimated accordingly to Target and Terrain characteristics.

The interactive 3D map highlights low travel time with cold colors and higher travel time using hotter colors.

How many Men are required for searching the area?

and where are they right now?

Tradeoff Solutions

Efficiency vs. Cost

Selection of Search Units

Search Units are gathered at the Base Camp (RED Marker) to search the green area within a given time.

SHARON offers tradeoff solutions by considering Cost in terms of distance between current position of each man and the base camp, and by considering operation efficiency in terms of fitting Decision makers objectives (e.g., time, number of search units, ..).
