[0002] Emergency resource dispatch is an important part of the disaster emergency management process. In the process of disaster emergency management, it is very common to have difficulty in rationally dispatching resources in multiple disaster-stricken areas and a variety of emergency materials. Therefore, the ultimate goal of disaster emergency management in the context of multiple disaster-stricken areas is to minimize casualties and socioeconomic losses. In the rescue process, material rescue is the key to meeting the survival needs of disaster victims and restoring development. Therefore, the efficient and accurate dispatch of emergency materials in a distributed environment has become a key factor in the disaster management process.

[0003] Regarding the dispatch of emergency supplies, under the general process framework, after the disaster-stricken area calls for material support, the distribution point in the rear accepts the task and starts transporting supplies. This model can indeed complete various supply tasks quickly and accurately under the condition of sufficient emergency resources. However, considering that emergency resources are not unlimited, the emergency resources of different disaster-stricken areas and distribution points need to be dispatched during the dispatch of emergency resources in a distributed environment. If it is only manually dispatched, if there are many areas, many types of emergency supplies, many factors to consider, and the status changes rapidly, it is insufficient to rely solely on manual judgment, and it is difficult to face complex scenarios.

[0028] Please refer to Figure 1In a preferred embodiment of the present invention, a method for negotiating and dispatching emergency resources in a distributed environment is provided, which is used for a server, namely a server of an emergency response system, for displaying information and processing support and supply information, so as to provide effective information supply for emergency response reference and assist commanders in rescue. A method for negotiating and dispatching emergency resources in a distributed environment includes steps S1, S2, S3, S4, S5, and S6.

[0029] S1, dividing the layout area of ​​emergency materials into grids, thereby obtaining a plurality of grid areas and numbering the grid areas, and numbering the emergency materials by type.

[0030] S2, according to the status of emergency materials in each grid area, obtain the status matrix of emergency materials to facilitate subsequent overall calculation, comparison and judgment;

[0031] S3, based on the received emergency material needs of each grid area, obtain the material demand of each emergency material in each grid area; based on the matching degree of the emergency materials to the needs of the people in the grid, obtain the value of different types of emergency materials in each grid area;

[0032] S4, define the grid area where the amount of emergency supplies is less than the amount of supplies demanded by the masses in the grid as the area to be replenished for emergency supplies to be replenished, and the emergency supplies to be replenished are the types of emergency supplies where the amount of resources in the area to be replenished is less than the corresponding emergency supplies demand, that is, if the amount of resources of the first category of emergency supplies in one grid area is less than the amount of supplies demanded by the masses for the first category of emergency supplies in the grid area, then the amount of resources of the first category of emergency supplies in the grid area is not enough to meet the demand in the grid, so the grid area is defined as the area to be replenished for the first category of emergency supplies, and the first category of emergency supplies are defined as the emergency supplies to be replenished. Of course, there may be multiple types of emergency supplies insufficiency in the same grid area, that is, multiple areas to be replenished for emergency supplies. The to-be-replenished area of ​​emergency materials to be replenished indicates that the replenishment of emergency materials in the to-be-replenished area needs to be replenished and dispatched; the grid area where the resource amount of the same type of emergency materials corresponding to the to-be-replenished emergency materials is greater than the material demand of the masses in the grid is defined as the alternative support area for the emergency materials to be replenished, that is, when the resource amount of the first type of emergency materials is greater than the consumption required for the supply task in the grid, it means that the resources are sufficient and surplus, and these areas are defined as the alternative support areas for the first type of emergency materials as alternative areas for outward supply.

[0033] S5, compare the value of the emergency supplies to be replenished in the area to be replenished with the value of the corresponding emergency supplies in each alternative support area, and the type of emergency supplies corresponding to the alternative support area is the type of emergency supplies to be replenished in the corresponding area to be replenished. The alternative support area corresponding to the emergency supplies value less than the value of the emergency supplies to be replenished in the area to be replenished is taken as the designated support area, that is, the alternative support area whose value of the same type of emergency supplies corresponding to the emergency supplies to be replenished is less than the value of the emergency supplies to be replenished in the corresponding area to be replenished is taken as the designated support area, and the resources of the emergency supplies to be replenished corresponding to the designated support area are dispatched to the corresponding area to be replenished. For example, when the first type of emergency supplies are the emergency supplies to be replenished, the value of the first type of emergency supplies in the alternative support area of ​​the first type of emergency supplies is fully calculated, and compared with the value of the first type of emergency supplies in the area to be replenished, and then the alternative support area whose value of the first type of emergency supplies is less than the value of the first type of emergency supplies in the area to be replenished is selected as the designated support area. This avoids the transportation of high-value emergency supplies to low-value areas.

[0034] S6, issuing a resource dispatching instruction, wherein the resource dispatching instruction is used to instruct to dispatch the resources of the emergency supplies to be replenished corresponding to the designated support area to the corresponding area to be replenished.

[0035] A preferred embodiment of the present invention provides a method for negotiation and scheduling of emergency resources in a distributed environment, which uses a server to realize automatic matching and negotiation scheduling of resources. The server defines and represents the emergency material layout area and the status of the emergency materials through steps S1 and S2, so that the status of the emergency materials can be expressed more vividly and is conducive to subsequent calculations; the value of the emergency materials in each grid area is obtained according to the emergency materials and the corresponding support and supply tasks, thereby providing a basis for subsequent resource scheduling; through steps S4 and S5, resource negotiation and scheduling are carried out, and high-value emergency materials are supplied by low-value emergency materials to maximize the value, so that the overall benefits of the support and supply process can be as large as possible; and compared with manual calculation and coordination, the present invention considers more factors and is more comprehensive, can take into account the overall situation, realize the maximum utilization of resource value, provide effective information decision-making for emergency disposal reference, and assist commanders in the allocation of rescue materials.

[0036] In some embodiments of the present invention, in step S3, the value of different types of emergency supplies in each grid area is calculated by the following formula:

[0037]

[0038] G(i,j) is the value of emergency supplies of type j in the grid area numbered i;

[0039] CER ijis the cost-effectiveness ratio of the j-type emergency supplies in the grid area numbered i;

[0040] Rs ij is the loss parameter of the j-type emergency supplies in the grid area numbered i, that is, the coefficient of possible loss of supplies during transportation;

[0041] α and β are the tendency coefficients of the gains and losses of the emergency material supply mission, respectively;

[0042] The above formula is used to evaluate the value of emergency supplies in each grid area, thus serving as an important basis and reference for maximizing the value target of the subsequent support and supply process.

[0043] In a specific embodiment of the present invention, the cost-effectiveness ratio is calculated by the following formula:

[0044] ;

[0045] Ct ij The resource quantity parameter consumed by the j-type emergency material in the grid area numbered i to complete the corresponding supply task. During the material transportation process, the material consumption may be different due to terrain and distance. ij To express this difference; Rw ij Rw is the coefficient of the urgency of the grid area numbered i for the j-type emergency supplies, ij The higher it is, the more urgent the people's needs are. By comparing resource consumption and benefits, we can get the cost-effectiveness ratio, which reflects the ratio of resource consumption to emergency rescue effect.

[0046] In a specific embodiment of the present invention, the parameters α and β satisfy the following constraints: , so that the range of parameters α and β is controllable and α and β constrain each other, so that there are certain constraints when adjusting the weights to avoid out-of-control parameters. α and β can be adaptively set according to the types of emergency materials to adapt to the characteristics of different emergency materials.

[0047] Reference Figure 2 In some embodiments of the present invention, step S5 specifically includes steps S51, S52, S53, S54 and S55.

[0048] S51, obtaining a set of material demand quantities of emergency materials to be replenished in the area to be replenished , A j Represents the demand for emergency supplies of type j; j=(1,2,3,...).

[0049] When the system distributes supply tasks, it will also form a distribution matrix. By comparing the corresponding emergency material status matrix with the distribution matrix of the support supply task distribution, it can directly and clearly obtain whether the emergency materials in each area are sufficient, and the amount of resources missing when they are insufficient. The amount of resources missing is the amount of material demand. Extract the data of resource shortage to form a collection of material demand There are multiple resource shortages in a disaster-affected area, such as , which means that there is a shortage of resources of Class 1 emergency supplies and Class 2 emergency supplies in the area to be replenished.

[0050] S52, judge in turn whether the value of the emergency supplies to be replenished in each alternative support area is less than the value of the emergency supplies to be replenished in the corresponding area to be replenished: if so, the corresponding alternative support area is used as the designated support area, so as to avoid dispatching emergency resources in the high-value grid area to the area to be replenished, thereby reducing the value of the resources. Instead, by dispatching low-value resources to high-value areas to be replenished, the value of emergency supplies is increased during the resource dispatching process.

[0051] S53, respectively calculating the difference between the value of the emergency supplies to be replenished in all designated support areas and the value of the emergency supplies to be replenished in the corresponding areas to be replenished;

[0052] S54, sorting all designated support areas according to the value difference from large to small to obtain a designated support area sequence;

[0053] S55, according to the sequence of the designated support areas, the resource replenishment dispatch is carried out in turn for the emergency supplies to be replenished in the replenishment area until the resource replenishment dispatch volume is satisfy: , where A cj The designated support area c is the dispatched supply quantity of the j type of emergency supplies to be replenished in the area to be replenished. c is the sequence number of the designated support area in the designated support area sequence, and n is the number of designated support areas for resource replenishment scheduling. The designated support area sequence may contain m areas, but not every area needs resource replenishment scheduling. The resources in the first few areas may be able to meet the resource supply scheduling quantity of the area to be replenished. At this time, the remaining designated support areas with higher value can be put on standby.

[0054] In a further embodiment of the present invention, step S55 further includes:

[0055] S56, according to the resource replenishment scheduling quantity of the emergency materials to be replenished in each designated support area in step S55, the corresponding own resource quantity of the emergency materials to be replenished in the designated support area is updated, so as to update the data to obtain the latest data for subsequent system judgment and analysis.

[0056] In a further embodiment of the present invention, if the number of areas to be replenished corresponding to the same type of emergency materials in step S4 is greater than 1, the areas to be replenished are sorted from large to small according to the value of the same type of emergency materials to be replenished in all the areas to be replenished, and step S5 is executed in sequence for the areas to be replenished according to the sorting order, so as to give priority to resource scheduling and arrangement for high-value areas, thereby achieving high-value use of low-value resources.

[0057] In a further embodiment of the present invention, wherein A cj Satisfies the following formula ;

[0058] in is the own resource volume of type j emergency supplies in designated support area c, B cj is the consumption of the supply mission of type j emergency supplies in the designated support area c, D cj It is the emergency reserve quantity of type j emergency materials in the designated support area c; thus ensuring that the outward supply dispatching quantity of the designated support area does not affect the supply task within its grid, and a certain margin is reserved for emergencies, so as to cope with complex and changing scenarios.

[0059] The present invention also provides an emergency resource negotiation and dispatching system in a distributed environment, comprising a region division and numbering module, a state matrix module, an emergency material value calculation module, a region definition module and a region screening module.
