The invention discloses a network
toughness evaluation method and
system for supply connection between an urban farmer market and a
community. The method comprises the following steps: acquiring grid
mobile phone signaling data, market AOI
boundary data and
community AOI
boundary data in a determined range; enabling grid units in the
mobile phone signaling data to be intersected with a market AOI boundary graph and a
community AOI boundary graph, and calculating a market connection weight and a community connection weight; the market and the community form a supply pair, an OD contact data column between the market section and the community section is generated, the point degree of the market section and the contact degree between the market section and the community section are calculated, and a
supply network between the farmer's market and the community is identified; counting day-by-day flow change in a set date of the market, selecting an impacted market case, and actually measuring a
toughness curve of the selected market. According to the method, the current network
toughness situation of supply connection between the urban farmer's market and the community can be identified, so that targeted improvement measures are put forward, and the ability of the farmer's market and the community to deal with emergencies is enhanced.
