  • Publication number: 20240289711
    Abstract: A method for hierarchically optimizing a scheduling plan of a heterogeneous helicopter fleet, comprising: step 1: summarizing important information in a disaster situation, and constructing a structured input mission scenario; step 2: constructing a scheduling problem model of the heterogeneous helicopter fleet, wherein the model is decomposed into two hierarchies including a route planning problem model and a mission assignment optimization model; step 3: designing the solution data structures, using the mission assignment matrix as the corresponding data structure for the mission assignment optimization model, and using the helicopter mission route as the corresponding data structure for the route planning problem model; step 4: combining the solution data structures and the route planning problem model, and developing a route planning solver; step 5: combining the solution data structures, the mission assignment optimization problem model and the route planning solver, developing a solver for the optimizat

  • Patent number: 11908032
    Abstract: A method for planning collaborative search-and-rescue missions using a plurality of search-and-rescue equipment in medium to far sea areas, includes: step 1: performing environmental modeling for maritime search-and-rescue missions; step 2: performing modeling for search-and-rescue modes using a plurality of search-and-rescue equipment; step 3: defining a maritime collaborative search-and-rescue mission planning model; based on the maritime collaborative search-and-rescue mission planning model, generating an overall matrix RP for the search-and-rescue mission planning using a plurality of search and rescue equipment; step 4: selecting target parameters, and defining a target function ƒ(RP) of the maritime collaborative search-and-rescue mission; based on an overall matrix RP of the maritime search-and-rescue mission environment model, the search-and-rescue mode model using a plurality of search-and-rescue equipment, and the overall matrix RP of the search-and-rescue mission planning using a plurality of sear
