| titleOfInvention | Integer programming-based epidemic spread blocking method in public transportation system |
| abstract | The invention discloses a method for blocking the spread of epidemics in a public transportation system based on integer programming. The method firstly constructs a public transportation network topology map, in which nodes and arcs respectively represent a public transportation station and an interval between two adjacent stations; and then according to the IC The historical card swiping data is calculated to obtain the passenger's alighting station and time, and the interval travel time matrix and the interval passenger flow matrix are calculated by time period; then based on the station sequence, interval travel time and interval passenger flow, a directed network with length and capacity is constructed; then From the perspective of virus transmission time and space, construct a public transport network accessibility model from the perspective of virus transmission. This model can calculate the virus transmission reachability between any stations and the comprehensive accessibility of the entire network; As the goal, a mixed integer programming model for bus network blocking was established; finally, the changes of accessibility values before and after different network blocking methods were comprehensively compared and analyzed, and the solution to blocking the spread of the epidemic was determined. |
