Embodiment
Invention provides a kind of emergency vehicle scheduling and personnel evacuation method towards the hazardous gas diffusion, and step is:
In the step 1, the gas leakage region of will causing danger respectively treat Dispersal Point according to hazard level carry out prioritization; The Dispersal Point of treating that the hazardous gas source of leaks is nearest has limit priority; Its concrete implementation procedure is: the gas leakage region of will causing danger is divided into the zone with different danger classess according to the gaseous diffusion model; Be divided into three layers of hazardous location in the present embodiment; Be respectively lethal zone, cause injury and distinguish and the sucting reaction district, the higher interior Dispersal Point of treating in zone of danger classes has higher priority, if there are a plurality of Dispersal Points of treating in the same area; Then nearer apart from the hazardous gas source of leaks Dispersal Point of treating has higher priority, and each is treated that Dispersal Point sorts according to priority from high to low.
Step 2, calculate treat respectively that Dispersal Point and each do not mated take refuge a little between distance; And calculate a residue galleryful of respectively taking refuge whether less than the max cap. (threshold values) of vehicle; If; Then this is taken refuge a little and the path that is remained between the Dispersal Point is made as infinity, otherwise be actual distance;
Step 3, from remaining not coupling treat choose the Dispersal Point priority the highest treat Dispersal Point; To have taking refuge of lowest distance value and a little treat the Dispersal Point coupling with this; The number of coupling equal this take refuge a little with the number of treating Dispersal Point in smaller value, will treat Dispersal Point then accordingly and number that a little the number of taking refuge deducts coupling obtains their residue number;
Step 4, calculating treat respectively whether the number of evacuation of treating of Dispersal Point is 0, if, then this is treated the Dispersal Point rejecting, if the number of evacuation that remains all is 0, then coupling finishes, otherwise gets back to step 2;
Step 5, calculate each car and arrive each and treat the moment of Dispersal Point; Priority order by treating Dispersal Point is dispatched vehicle; The Dispersal Point priority scheduling of treating that residue priority is high arrives the vehicle that this treats that Dispersal Point is minimum constantly; When vehicle accomplish once from treat Dispersal Point to a little the transportation of taking refuge of its coupling after carry out step 5 again, finish until remaining Dispersal Point is mated;
If each vehicle is accepted scheduling first after hazardous gas is leaked, then each car arrive each treat Dispersal Point the moment=vehicle arrives the moment+parking lot and distance/speed of a motor vehicle of treating Dispersal Point in parking lot.
Otherwise, each car arrive the moment (cumulative time)=this vehicle that each (0-n) treat Dispersal Point arrive last one treat Dispersal Point the moment+this car from the last time treat Dispersal Point to coupling take refuge a little duration+this car from take refuge an arrival this treat the Dispersal Point duration.If i car of hypothesis accomplished once from j and treated Dispersal Point to transportation a little of taking refuge of k coupling, that i car arrives the individual moment (the cumulative time)=i car of treating Dispersal Point of h (0-n) and arrives j the moment+an i car of treating Dispersal Point and treat that from j Dispersal Point matees a duration+i car of taking refuge a little to k and matees an individual duration of treating Dispersal Point of arrival h (0-n) of taking refuge from k.
Below above-mentioned steps is made further explanation.
Treat in the above-mentioned steps that the Dispersal Point and the principle of a little mating of taking refuge are: by treating that the Dispersal Point priority order matees (the preferential coupling that priority is high); Optimal path length was lacked most during each coupling was got that residue is available and taken refuge a little; When the residue galleryful of taking refuge during less than the max cap. of vehicle, the coupling of Dispersal Point is treated in this no longer acceptance of taking refuge a little.
As shown in Figure 1; Its concrete steps are: Dispersal Point begins to mate from the highest the treating of priority; What optimal path length was lacked most in selecting that residue is available and taking refuge a little matees; The residue number of Dispersal Point is treated in adjustment and a residue galleryful of taking refuge (if certain residue galleryful of taking refuge then arrives remaining Dispersal Point in this path of taking refuge a little and is changed to infinity less than the vehicle max cap. at this moment); Finish and mate for the first time afterwards, then continue to mate again, treat Dispersal Point until having mated first by top principle if the highest Dispersal Point of treating of priority also has the residue number.The back is carried out the coupling of time priority again, finishes until final coupling.
The principle of operation dispatching is in the above-mentioned steps: by treating that the Dispersal Point priority order dispatches (priority scheduling that priority is high); Arrival is chosen in each scheduling, and this treats the Dispersal Point vehicle of (time of arrival is the shortest) the soonest, if equate that it is the fastest to choose the speed of a motor vehicle time of arrival.
As shown in Figure 2, its concrete steps are: begin to dispatch from the highest Dispersal Point of priority, this treats the shortest vehicle of Dispersal Point time (if equating that the speed of then picking up the car is vehicle faster time of arrival) to choose arrival; Revise this residue of treating Dispersal Point treat number of evacuation and with its coupling residual capacity a little of taking refuge; Revise the arrival of this vehicle next time respectively treat the moment of Dispersal Point (this vehicle arrive last one treat Dispersal Point the moment+this car from the last time treat Dispersal Point to coupling take refuge a little duration+this car from take refuge an arrival this treat the Dispersal Point duration); Judge this and treat that the Dispersal Point scheduled assigns, the number that this Dispersal Point then is set is 0, skips to next and treats that Dispersal Point dispatches, and finishes until all Dispersal Point scheduling of treating.
Before carrying out above-mentioned steps; Also need obtain some parameters, be respectively: the received protection personnel's that the personnel amount information of treating Dispersal Point in the position of the information of three layers of hazardous location, every road and barrier point, disaster point and the disaster zone, the position of sanctuary and sanctuary are remaining capacity information, position, parking lot, type of vehicle and number.
