acquiring the load degree of a public activity venue, wherein the load degree is represented by the degree that the pedestrian flow in the public activity venue exceeds the designed capacity, and the excess amount of the pedestrian flow is divided into different grades which respectively represent different degrees of overload operation of the public activity venue;
specifically, the load level of the public activity venue is calculated by the following formula:
load level of public activity venue = w1 a load level days + w 2B load level days + …;
in the formula, w1 and w2 represent the weights of the A load level and the B load level respectively, and … represents the multiplication of the days of other load levels and the corresponding weights;
it should be understood that the higher the load level, the greater the impact on the public event venue, and the greater its corresponding weight;
acquiring a load score of the public activity venue according to the load degree of the public activity venue;
and after the load score of the public activity venue is subjected to normalization processing, obtaining the service degree score of the public activity venue.
Correspondingly, evaluation indexes are set according to the characteristics of the tunnel, the road, the traffic junction, the public community building and the endowment organization, and the practical degree scores of the tunnel, the road, the traffic junction, the public community building and the endowment organization can be respectively obtained.
In step 260, obtaining a criticality score of each of the facilities according to the importance score, the failure severity score, the operating status score and the usage degree score of each of the facilities, including:
and acquiring the weights of the importance score, the failure severity score, the operation state score and the use degree score in the criticality score, and acquiring the criticality score of each facility according to the importance score, the failure severity score, the operation state score, the use degree score and the weight of each score in the criticality score.
That is, the criticality score of each facility is calculated by the following formula:
criticality score of a facility = w1 + importance score of a facility + w2 + failure severity score of a facility + w3 + operating status score of a facility + w4 + degree of use score of a facility;
in the formula, w1, w2, w3 and w4 are weights of the importance score, the failure severity score, the operating condition score and the usage degree score, respectively.
In step 270, the importance scores of the facilities in the facility group are compared, and the facilities with the criticality scores greater than or equal to the preset threshold value are identified as the key facilities in the facility group.
The identification method of the key facilities in the facility group utilizes the unique technical characteristics of the identification method of the key facilities in the facility group to deduce, thereby realizing the beneficial effect of solving the technical problems in the background technology.
The identification method of the key facilities in the facility group belongs to a multi-attribute decision-making model, wherein multi-attribute decision-making (multiple attribute decision-making) refers to the integration and sequencing of criterion values under multiple criteria of multiple schemes. In the embodiment of the invention, the key of the facility can be quantitatively evaluated through different multi-attribute decision models according to the established evaluation index systems of different types of urban ground public infrastructures, and then the key facility in the facility group is judged according to the quantitative result.
