Description

Technical Field

[0001] The present application relates to the technical field of urban planning, and more specifically, to a method, device, electronic device, and storage medium for the site selection and planning of elderly care facilities. Background Art

[0002] With the accelerating development of population aging, the shortage of elderly care facilities (such as nursing homes, senior apartments, day care centers for the elderly, home-based elderly care service centers, etc.) has become an increasingly prominent social problem. Therefore, improving the construction of elderly care facilities has become one of the key points in urban planning work.

[0003] In urban planning work, when selecting the site for elderly care facilities, multiple factors such as the characteristics of population distribution, the distribution of elderly care facilities, traffic convenience, and environmental suitability need to be considered. Generally, it relies on planners to make plans based on experience, which not only has low efficiency, but also the rationality of the planning scheme is limited by the experience of the planners, resulting in poor rationality of the planning scheme. Summary of the Invention

[0004] The purpose of the present application is to provide a method, device, electronic device, and storage medium for the site selection and planning of elderly care facilities, which can improve the planning efficiency of the site selection and planning of elderly care facilities and the rationality of the planning scheme.

[0005] In a first aspect, the present application provides a method for the site selection and planning of elderly care facilities, including the steps of:

[0006] A1. Divide the area to be planned into grid areas to obtain a plurality of grid areas;

[0007] A2. Obtain the historical population information, existing elderly care facility information, distribution information of elderly care supporting facilities, distribution information of transportation facilities, and distribution information of environmental impact facilities of the area to be planned;

[0008] A3. Calculate the demand for elderly care facility beds in each grid area after a preset time according to the historical population information;

[0009] A4. Calculate the target increment of elderly care facility beds in each grid area according to the existing elderly care facility information and the demand for elderly care facility beds;

[0010] A5. Calculate the spatial suitability of each grid area according to the distribution information of elderly care supporting facilities, the distribution information of transportation facilities, and the distribution information of environmental impact facilities;

[0011] A6. Plan the distribution grid and the corresponding number of beds of new elderly care facilities according to the target increment of elderly care facility beds and the spatial suitability of each grid area.

[0012] The method for site selection and planning of the elderly care facility, after dividing the planned area into grids, automatically determines the distribution grids of the beds for newly added elderly care facilities and the corresponding number of beds according to the historical population information, existing elderly care facility information, distribution information of elderly care supporting facilities, distribution information of transportation facilities, and distribution information of environmental impact facilities in each grid area, without the need for manual planning. The rationality of the planning scheme is no longer limited by the experience of planners, thereby improving the planning efficiency of the site selection and planning of elderly care facilities and the rationality of the planning scheme.

[0013] Preferably, the historical population information includes the total population quantity of the planned area in multiple historical years, the quantity of elderly people in the planned area, and the population distribution location information of the planned area;

[0014] Step A3 includes:

[0015] A301. According to the total population quantity of the planned area, the quantity of elderly people in the planned area, and the population distribution location information of the planned area in each historical year, count the total population quantity of each grid area and the quantity of elderly people in each grid area in each historical year;

[0016] A302. According to the total population quantity of each grid area and the quantity of elderly people in each grid area in each historical year, predict the quantity of elderly people in each grid area after a preset time;

[0017] A303. Calculate the demand for beds in elderly care facilities in each grid area after a preset time according to the quantity of elderly people in each grid area after a preset time.

[0018] Since the population distribution will change over time and the construction of elderly care facilities requires a certain period, if only the current population distribution is considered when conducting the site selection and planning of elderly care facilities, it is difficult to ensure that the elderly care needs at that time can be met after the completion of the construction of elderly care facilities, resulting in a relatively low rationality of the planning scheme; here, by predicting the future distribution of elderly people and conducting the site selection and planning of elderly care facilities according to the future distribution of elderly people, it is ensured that the elderly care needs at that time can be met after the completion of the construction of elderly care facilities, thereby improving the rationality of the planning scheme.

[0019] Preferably, the existing elderly care facility information includes the types of each existing elderly care facility, the locations of each existing elderly care facility, and the number of beds in each existing elderly care facility;

[0020] Step A4 includes:

[0021] A401. Determine the influence areas of each existing elderly care facility according to the types of each existing elderly care facility and the locations of each existing elderly care facility;

[0022] A402. Calculate the existing stock of elderly care facility beds in each of the grid areas based on the influence areas of the existing elderly care facilities and the number of beds in each of the existing elderly care facilities;

[0023] A403. Calculate the target increment of elderly care facility beds in each of the grid areas based on the demand for elderly care facility beds and the existing stock of elderly care facility beds in each of the grid areas.

[0024] Various types of elderly care facilities have different influence areas. When the elderly population within the influence area selects an elderly care facility, there is a high probability that they will choose the elderly care facility corresponding to that influence area. Generally, the scope of the influence area is larger than that of a single grid area. If only the beds of the existing elderly care facilities are regarded as the existing stock of elderly care facility beds in the single grid area where the existing elderly care facility is located, it does not conform to the actual usage situation, thus affecting the rationality of the final planning result.

[0025] Preferably, the distribution information of elderly care facilities includes the types of each elderly care facility and the locations of each elderly care facility;

[0026] The distribution information of transportation facilities includes the types of each transportation facility and the locations of each transportation facility;

[0030] A502. Based on the types of each transportation facility and the locations of each transportation facility, count the types and quantities of transportation facilities in each of the grid areas to calculate the transportation convenience in each of the grid areas;

[0032] A504. Calculate the spatial suitability of each of the grid areas based on the perfection degree of elderly care facilities, the transportation convenience, and the environmental suitability in each of the grid areas.

[0033] Preferably, the target increment of elderly care facility beds includes the bed increment of at least one type of newly added elderly care facility;

[0034] Step A6 includes successively taking various newly added elderly care facilities as target facilities and performing the following:

[0035] B1. Establish a first tabu list and initialize the first tabu list to be empty;

[0036] B2. Perform a descending order sorting on each of the grid regions that are not in the first tabu list according to the spatial suitability;

[0037] B3. Select the grid region ranked first in the sorting that is not in the first tabu list as a distribution grid of the target facility;

[0038] B4. Determine the influence area of the target facility according to the position of the distribution grid and the type of the target facility, and use the grid regions that are not in the first tabu list within the influence area of the target facility as effective influence grids;

[0039] B5. Determine the number of beds of the target facility in the distribution grid according to the bed increment of the target facility corresponding to each of the effective influence grids, and add the effective influence grids to the first tabu list;

[0040] B6. Judge whether a preset end condition is satisfied according to the first tabu list. If it is satisfied, end the planning; otherwise, return to execute step B2.

[0041] Preferably, the target bed increment of the elderly care facility includes the bed increment of at least one type of newly added elderly care facility;

[0042] Step A6 includes successively taking various newly added elderly care facilities as target facilities and performing the following:

[0043] Based on the ant colony algorithm, perform the planning of the distribution grid and the corresponding number of beds of the target facility according to the bed increment of the target facility corresponding to each of the grid regions and the spatial suitability.

[0060] It should be noted that similar reference numerals and letters indicate similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. At the same time, in the description of the present application, terms such as "first" and "second" are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0061] Please refer to Figure 1 , Figure 1 which is a method for site selection and planning of pension facilities in some embodiments of the present application, including the steps:

[0062] A1. Divide the area to be planned into grids to obtain multiple grid areas;

[0063] A2. Obtain the historical population information, existing pension facility information, distribution information of supporting elderly facilities, distribution information of transportation facilities, and distribution information of environmental impact facilities in the area to be planned;

[0064] A3. Calculate the bed demand of pension facilities in each grid area after a preset time according to the historical population information;

[0065] A4. Calculate the target increment of the bed of pension facilities in each grid area according to the existing pension facility information and the bed demand of pension facilities;

[0066] A5. Calculate the space suitability of each grid area according to the distribution information of supporting elderly facilities, distribution information of transportation facilities, and distribution information of environmental impact facilities;

[0067] A6. According to the target increment of the beds in the elderly care facilities in each grid area and the spatial suitability, plan the distribution grids of the newly added elderly care facilities and the corresponding number of beds.

[0068] After the grid division of the area to be planned, the location planning method of the elderly care facilities automatically determines the distribution grids of the beds in the newly added elderly care facilities and the corresponding number of beds according to the historical population information, existing elderly care facility information, distribution information of elderly care supporting facilities, distribution information of transportation facilities, and distribution information of environmental impact facilities in each grid area, without the need for manual planning. The rationality of the planning scheme is no longer limited by the experience of the planners, thus improving the planning efficiency of the location planning of the elderly care facilities and the rationality of the planning scheme.

[0069] Among them, the area to be planned, that is, the target area for the location planning of the elderly care facilities, can be an urban area, a sub - district area under a city, or a street area, etc.

[0070] Among them, in step A1, when dividing the grid of the area to be planned, the minimum circumscribed rectangle of the area to be planned can be generated first, and then the minimum circumscribed rectangle is divided into grids. Then, the grid areas that do not contain the parts located within the area to be planned are marked as invalid grid areas, and the grid areas that are at least partially located within the area to be planned are marked as valid grid areas.

[0071] Specifically, the minimum circumscribed rectangle is divided into grids by horizontal grid lines and vertical grid lines. The horizontal grid lines are parallel to the long side of the minimum circumscribed rectangle, and the vertical grid lines are parallel to the short side of the minimum circumscribed rectangle. The divided grid areas are square areas with the same size. Among them, the side length of the grid area can be preset according to actual needs, but it is necessary to ensure that the side length of the grid area is less than the influence diameter of various elderly care facilities (the influence diameter of the elderly care facilities is the diameter of the circular influence range centered on the elderly care facilities. The probability that the elderly population within the circular influence range of the elderly care facilities chooses to use this elderly care facility is greater than the probability of using the same type of elderly care facilities outside the circular influence range; the influence diameters of various elderly care facilities can be obtained through data statistics, and the influence diameters of different types of elderly care facilities may be different. For example, the influence diameters of nursing homes and elderly apartments are 2000m, and the influence diameters of day care centers for the elderly and home - based elderly care service centers are 1000m, but not limited to this); when the side line of the minimum circumscribed rectangle is not an integer multiple of the preset side length of the grid area, the side line of the minimum circumscribed rectangle can be increased to an integer multiple of the preset side length of the grid area before grid division.

[0072] Among them, the historical population information includes the total population quantity, the elderly population quantity, and the population distribution location information of the planned area in multiple historical years (the specific number of historical years can be set according to actual needs). Among them, the starting age standard for the elderly is determined according to the relevant regulations of the region where the planned area is located. For example, the starting age standard is 60 years old (that is, the population aged 60 and above is the elderly population), but it is not limited to this.

[0073] Among them, the existing elderly care facility information includes the types of each existing elderly care facility (that is, the elderly care facilities currently in use), the locations of each existing elderly care facility, and the number of beds in each existing elderly care facility. Among them, the types of elderly care facilities include at least one of nursing homes, elderly apartments, day care centers for the elderly, and home-based elderly care service centers, etc., but it is not limited to this. Among them, the number of beds in this article does not refer to the number of beds provided for the elderly in a narrow sense in elderly care facilities, but generally refers to the number of places where elderly care services can be provided in elderly care facilities; for example, for nursing homes and elderly apartments, since accommodation services are provided, the number of beds is equal to the number of beds provided for the elderly (the number of these beds is the number of places where the corresponding elderly care facility can provide elderly care services); for day care centers for the elderly and home-based elderly care service centers, since accommodation services are not provided, the number of beds is equal to the number of places where elderly care services can be provided.

[0074] Among them, the distribution information of elderly care supporting facilities includes the types of each elderly care supporting facility and the locations of each elderly care supporting facility. The types of elderly care supporting facilities include at least one of medical facilities, cultural facilities (such as activity venues for various cultural and sports activities provided for the elderly in places like the elderly's home, etc., to provide a communication platform for the elderly), elderly education facilities (such as institutions like senior universities that provide education for the elderly to enrich the spiritual life of the elderly), and public recreation facilities (such as parks, squares, etc.), etc., but it is not limited to this.

[0075] Among them, the distribution information of transportation facilities includes the types of each transportation facility and the locations of each transportation facility. The types of transportation facilities include at least one of high-speed and expressways, main roads, and public transportation facilities (such as bus stops, subway stations, etc.), etc., but it is not limited to this.

[0076] Among them, the environmental impact facility distribution information includes the types of each environmental impact facility and the locations of each environmental impact facility. The types of environmental impact facilities include at least one of industrial facilities, logistics facilities, hazardous facilities (such as gas facilities, power supply facilities, sewage treatment facilities, etc.), primary schools, and kindergartens, but are not limited thereto. It should be noted that the environmental impact facilities here do not mean that the corresponding facilities have an impact on the natural environment, but rather that the environment where the corresponding facilities are located has an impact on the personal safety and physical and mental health of the elderly population. For example, industrial facilities are likely to produce pollution and affect the physical health of the elderly population, the noise of logistics facilities will affect the physical health of the elderly population, hazardous facilities are likely to endanger the personal safety of the elderly population, and there are more children gathered near primary schools and kindergartens. The vitality of children can enable the elderly population to live a more positive life, thus contributing to the mental health of the elderly population.

[0077] Specifically, step A3 includes:

[0078] A301. According to the total population quantity, the elderly population quantity, and the population distribution location information of the planned area in each historical year, count the total population quantity of each grid area and the elderly population quantity of each grid area in each historical year;

[0079] A302. According to the total population quantity of each grid area and the elderly population quantity of each grid area in each historical year, predict the elderly population quantity of each grid area after a preset time;

[0080] A303. Calculate the demand for elderly care facility beds in each grid area after a preset time according to the elderly population quantity of each grid area after a preset time.

[0081] Since the population distribution will change over time and the construction of elderly care facilities requires a certain period, if only the current population distribution is considered when planning the location of elderly care facilities, it will be difficult to ensure that the elderly care needs can be met after the construction of elderly care facilities is completed, resulting in a relatively low rationality of the planning scheme; here, by predicting the future elderly population distribution and planning the location of elderly care facilities according to the future elderly population distribution, it is ensured that the elderly care facilities can meet the elderly care needs at that time after completion, thereby improving the rationality of the planning scheme.

[0082] Among them, in step A301, for invalid grid areas, the total population quantity of each grid area and the elderly population quantity of each grid area in each historical year are both set to zero. Thus, the predicted elderly population quantity and the demand for elderly care facility beds in invalid grid areas after a preset time are both zero.

[0083] Among them, in step A302, based on the total population and the elderly population in each grid area for each historical year, the one-variable linear regression analysis method and / or the Malthusian population model can be used to predict the elderly population in each grid area after a preset time. Using the one-variable linear regression analysis method and the Malthusian population model to predict the elderly population is a prior art. Among them, the prediction formula for using the one-variable linear regression analysis method to predict the elderly population is: , where t is time, is the elderly population in the i-th grid area corresponding to time t, , are both regression parameters of the i-th grid area (obtained by analyzing the total population and the elderly population in the i-th grid area for each historical year through the one-variable linear regression analysis method); the prediction formula for using the Malthusian population model to predict the elderly population is: , is the proportionality parameter of the i-th grid area, is the exponential parameter of the i-th grid area ( and are obtained by analyzing the total population and the elderly population in the i-th grid area for each historical year through the Malthusian population model), is the base of the natural logarithm.

[0084] When using the one-variable linear regression analysis method and the Malthusian population model to predict the elderly population in each grid area after a preset time, the one-variable linear regression analysis method and the Malthusian population model can be used to predict the elderly population in each grid area after a preset time respectively, and then the average value of the prediction result of the elderly population by the one-variable linear regression analysis method and the prediction result of the elderly population by the Malthusian population model in the same grid area can be calculated as the elderly population in the corresponding grid area after a preset time.

[0085] Among them, the preset time can be set according to actual needs, generally 5 years, but not limited to this.

[0086] Among them, the demand for elderly care facility beds includes the demand for beds in various elderly care facilities. In step A303, the following formula can be used to calculate the demand for elderly care facility beds in each grid area after a preset time: ;

[0087] Among them, is the demand for beds of the j-th type of elderly care facility in the i-th grid area after a preset time, is the elderly population in the i-th grid area after a preset time, $p_j$ is the demand ratio for the $j$-th type of elderly care facility (which reflects the proportion of the number of residents who are willing to choose this type of elderly care facility for elderly care in the total population in the planned area, and this demand ratio can be determined through questionnaire surveys), and $m$ is the total number of types of elderly care facilities (for example, when the types of elderly care facilities only include nursing homes, elderly apartments, day care centers for the elderly, and home-based elderly care service centers, $m = 4$).

[0088] Specifically, step A4 includes:

[0089] A401. Determine the influence area of each existing elderly care facility according to the type and location of each existing elderly care facility;

[0090] A402. Calculate the existing stock of elderly care facility beds in each grid area according to the influence area of each existing elderly care facility and the number of beds in each existing elderly care facility;

[0091] A403. Calculate the target increment of elderly care facility beds in each grid area according to the demand for elderly care facility beds and the existing stock of elderly care facility beds in each grid area.

[0092] Each type of elderly care facility has a different influence area. When the elderly population in the influence area selects an elderly care facility, there is a high probability of choosing the elderly care facility corresponding to this influence area. Generally, the scope of the influence area is larger than the scope of a single grid area. If only the beds of the existing elderly care facility are regarded as the existing stock of elderly care facility beds in the single grid area where the existing elderly care facility is located, it does not conform to the actual usage situation, thus affecting the rationality of the final planning result.

[0093] Among them, step A401 includes successively taking each existing elderly care facility as the target existing elderly care facility and executing:

[0094] Determine the grid area where the target existing elderly care facility is located according to the location of the target existing elderly care facility as the central grid;

[0095] Obtain the influence diameter of the target existing elderly care facility according to the type of the target existing elderly care facility; for example, query the corresponding influence diameter from the influence diameter query table according to the type of the target existing elderly care facility. The influence diameter query table records the influence diameters of various types of elderly care facilities (the influence diameters of various types of elderly care facilities are obtained through data statistics in advance);

[0096] Determine the equivalent influence range of the target existing elderly care facility according to the central grid and the influence diameter of the target existing elderly care facility; the equivalent influence range of the target existing elderly care facility refers to a circular area with the center point of the central grid as the center and the influence diameter of the target existing elderly care facility as the diameter;

[0097] Determine a characteristic square area that is concentric with the equivalent influence range of the existing pension facility for the target, and use the area composed of the effective grid areas within this characteristic square area as the influence area of the existing pension facility for the target; the characteristic square area is a square area that meets the following conditions:

[0098] Condition 1: The center point of the characteristic square area coincides with the center of the circle of the equivalent influence range of the existing pension facility for the target;

[0099] Condition 2: The side length of the characteristic square area is an odd multiple of the side length of a single grid area;

[0100] Condition 3, , is half of the influence diameter of the existing pension facility for the target, is half of the diagonal length of the characteristic square area, is the side length of a single grid area.

[0101] For all effective grid areas within the characteristic square area, they are all at least partially located within the corresponding equivalent influence range. For example, Figure 4 In, grid area A is the grid area where an existing pension facility for a target is located. Thus, grid area A is the central grid of the existing pension facility for the target, circular area y1 is the equivalent influence range of the existing pension facility for the target, and square F1 is the characteristic square area (the effective grid areas at the four corners within this square F1 are partially located within circular area y1, and other effective grid areas are all located within circular area y1).

[0102] Among them, the bed stock of pension facilities includes the bed stock of various types of pension facilities. Step A402 includes:

[0103] Calculate the bed stock of the corresponding type of pension facilities in each grid area brought by each existing pension facility according to the following formula: ;

[0104] Among them, is the bed stock of the corresponding type of pension facilities (i.e., the pension facility type to which the i-th existing pension facility belongs) in the j-th grid area brought by the i-th existing pension facility, is the number of beds of the i-th existing pension facility, is the number of grid areas (effective grid areas) within the influence area of the i-th existing pension facility, is the influence area of the i-th existing pension facility, indicates that the j-th grid area belongs to the grid areas within the influence area of the i-th existing pension facility, indicates that the j-th grid area does not belong to the grid areas within the influence area of the i-th existing pension facility;

[0105] Calculate the bed stock of various old facilities in each grid area according to the following formula: ;

[0106] Wherein, is the bed stock of the k-th type of old facility in the j-th grid area, is the total number of existing old facilities belonging to the k-th type of elderly care facility, is the bed stock of the corresponding type of old facility (i.e., the k-th type of old facility) in the j-th grid area brought by the i-th existing old facility belonging to the k-th type of elderly care facility.

[0107] Among them, the target increment of the beds in elderly care facilities includes the target increment of the beds in various elderly care facilities. Step A403 includes calculating the target increment of the beds in various elderly care facilities in each grid area according to the following formula: ;

[0108] Wherein, is the target increment of the beds of the k-th type of elderly care facility in the j-th grid area, is the demand for the beds of the k-th type of elderly care facility in the j-th grid area after a preset time.

[0109] Specifically, step A5 includes:

[0110] A501. According to the types and locations of various elderly care facilities, count the types and quantities of elderly care facilities in each grid area to calculate the perfection degree of elderly care facilities in each grid area;

[0111] A502. According to the types and locations of various transportation facilities, count the types and quantities of transportation facilities in each grid area to calculate the transportation convenience of each grid area;

[0112] A503. According to the types and locations of various environmental impact facilities, count the types and quantities of environmental impact facilities in each grid area to calculate the environmental suitability of each grid area;

[0113] A504. Calculate the spatial suitability of each grid area according to the perfection degree of elderly care facilities, transportation convenience and environmental suitability of each grid area.

[0114] Among them, in step A501, the improvement degree of the elderly care facilities in each invalid grid area is set to a preset minimum value (a preset negative value, which can be specifically set according to actual needs), and the weighted sum of the quantities of various types of elderly care facilities in each valid grid area is calculated as the improvement degree of the elderly care facilities in the corresponding valid grid area. Among them, the weight factors corresponding to various types of elderly care facilities can be determined by using the impact factor AHP weight analysis method or set manually, but not limited to this; it should be noted that for medical facilities, cultural facilities, elderly education facilities, and public recreation facilities, the more the quantity, the more beneficial it is to ensure the physical and mental health of the elderly. Therefore, the corresponding weight factors are all positive.

[0115] Among them, in step A502, the traffic convenience of each invalid grid area is set to a preset minimum value (a preset negative value, which can be specifically set according to actual needs), and the weighted sum of the quantities of various types of traffic facilities in each valid grid area is calculated as the traffic convenience of the corresponding valid grid area. Among them, the weight factors corresponding to various types of traffic facilities can be determined by using the impact factor AHP weight analysis method or set manually, but not limited to this; it should be noted that for high-speed and expressways, main roads, and public transportation facilities, the more the quantity, the more beneficial it is for travel. Therefore, the corresponding weight factors are all positive.

[0116] Among them, in step A503, the environmental suitability of each invalid grid area is set to a preset minimum value (a preset negative value, which can be specifically set according to actual needs), and the weighted sum of the quantities of various types of environmental impact facilities in each valid grid area is calculated as the environmental suitability of the corresponding valid grid area. Among them, the weight factors corresponding to various types of environmental impact facilities can be determined by using the impact factor AHP weight analysis method or set manually, but not limited to this; it should be noted that the existence of industrial facilities, logistics facilities, and dangerous facilities is not conducive to the personal safety and physical and mental health of the elderly. Therefore, the corresponding weight factors are negative, while primary schools and kindergartens are beneficial to the physical and mental health of the elderly. Therefore, the corresponding weight factors are positive.

[0117] Among them, in step A504, the weighted sum of the improvement degree of the elderly care facilities, traffic convenience, and environmental suitability of each grid area is calculated as the spatial suitability of the corresponding grid area. Among them, the weight factors of the improvement degree of the elderly care facilities, traffic convenience, and environmental suitability can be determined by using the impact factor AHP weight analysis method or set manually, but not limited to this.

[0118] Among them, the target increment of the beds in elderly care facilities includes the bed increments of at least one type of newly added elderly care facility. The newly added elderly care facility is the elderly care facility that needs to be added. The distribution grid of the newly added elderly care facility is the grid area where the newly added elderly care facility is located. The number of beds of the newly added elderly care facility in the distribution grid refers to the number of beds that the newly added elderly care facility set in the distribution grid needs to provide.

[0119] In some alternative embodiments, step A6 includes successively taking various newly added elderly care facilities as target facilities and performing the following:

[0120] B1. Establish a first tabu list and initialize the first tabu list to be empty;

[0121] B2. Sort all grid regions not in the first tabu list in descending order according to spatial suitability;

[0122] B3. Select the grid region ranked first in the sorting that is not in the first tabu list as a distribution grid for the target facility;

[0123] B4. Determine the influence area of the target facility according to the position of the distribution grid and the type of the target facility (the method for determining the influence area refers to the foregoing), and use the grid regions within the influence area of the target facility that are not in the first tabu list (as valid grid regions) as valid influence grids;

[0124] B5. Determine the number of beds of the target facility in the distribution grid according to the bed increment of the target facility corresponding to each valid influence grid, and add the valid influence grids to the first tabu list;

[0125] B6. Judge whether a preset end condition is satisfied according to the first tabu list. If it is satisfied, end the planning; otherwise, return to execute step B2.

[0126] Finally, through the above method, the distribution grids of each type of newly added elderly care facility and the bed increment in each distribution grid are obtained. After obtaining this data, planners can select the addresses of newly added elderly care facilities and design the building scale of newly added elderly care facilities according to the specific building distribution in the distribution grids; thus, this method can provide a basis for the address selection and building scale design of newly added elderly care facilities to improve the planning efficiency and the rationality of the planning results.

[0127] In some embodiments, in step B5, calculate the sum of the bed increments of the target facility corresponding to each valid influence grid as the number of beds of the target facility in the distribution grid obtained in step B3.

[0128] Sometimes, the sum of the bed increments of the target facility corresponding to each valid influence grid may be relatively large and exceed the bearing capacity of a single distribution grid. At this time, the valid influence grids can be added as distribution grids, so as to distribute the required bed increment (i.e., the sum of the bed increments of the target facility corresponding to each valid influence grid) to multiple distribution grids. Therefore, in some other embodiments, step B5 includes:

[0129] Calculate the sum of the bed increments of the target facility corresponding to each valid influence grid, denoted as the first bed increment sum z1;

[0130] If the effective influence grid only includes the distribution grid obtained in step B3, then take the first bed increment and z1 as the number of beds of the target facility in the distribution grid obtained in step B3;

[0131] If there are more than one effective influence grid and the first bed increment and z1 are not greater than the preset increment upper limit v (which can be set according to actual needs), then take the first bed increment and as the number of beds of the target facility in the distribution grid obtained in step B3;

[0132] If there are more than one effective influence grid and the first bed increment and z1 are greater than the preset increment upper limit v, then take all the effective influence grids as distribution grids, and calculate the number of beds of the target facility in each distribution grid according to the following formula: ;

[0133] Among them, is the number of beds of the target facility in the i-th distribution grid, is the spatial suitability of the i-th distribution grid, is the spatial suitability of the j-th distribution grid, and U is the number of distribution grids.

[0134] Among them, in step B6, the preset end condition is that all effective grids have been added to the first tabu list.

[0135] In some other alternative embodiments, step A6 includes sequentially taking various newly added elderly care facilities as target facilities and executing:

[0136] Based on the bed increment and spatial suitability of the target facility corresponding to each grid area, and based on the ant colony algorithm, plan the distribution grid of the target facility and the corresponding number of beds.

[0137] Specifically, it includes the steps:

[0138] C1. Initialize the pheromone concentration between each grid area and the selection probability between each grid area, and generate a second tabu list and a distribution grid set;

[0139] C2. Initialize the second tabu list and the distribution grid set to be empty;

[0140] C3. Add all invalid grid areas to the second tabu list;

[0141] C4. Randomly place a new ant into a valid grid area, take the valid grid area where the new ant is placed as the first distribution grid, determine the influence area of the first distribution grid, add the first distribution grid to the set of distribution grids, and add all valid grid areas within the influence area of the first distribution grid to the second tabu list; the influence area of a distribution grid refers to the influence area when the target facility is set in this distribution grid (thus, the influence area of the first distribution grid is the influence area when the target facility is set in the first distribution grid; the determination method of this influence area refers to the previous text).

[0142] C5. The new ant gradually selects and transfers distribution grids from valid grid areas not in the second tabu list according to the selection probabilities between valid grid areas, add all valid grid areas within the influence area of the selected distribution grid to the second tabu list, and add the selected distribution grid to the set of distribution grids until all valid grid areas are added to the second tabu list.

[0143] C6. According to the set of distribution grids and the bed increment and space suitability of the target facility corresponding to each grid area, determine the number of beds of the target facility in each distribution grid in the set of distribution grids, obtain a planning result (the planning result includes each distribution grid in the set of distribution grids and the number of beds of the target facility in each distribution grid), calculate the fitness value, and update the optimal planning result according to the fitness value.

[0144] C7. When the preset termination condition is met, end the planning of the current target facility and take the optimal planning result as the final site selection plan of the target facility; when the preset termination condition is not met, update the pheromone concentration and the selection probability between each grid area, and then return to execute step C2.

[0145] Among them, in step C1, the pheromone concentration between each grid area can be initialized to a preset concentration (which can be set according to actual needs), and the selection probability between each grid area can be initialized through the following steps:

[0146] Calculate the heuristic information between each grid area according to the following formula: ;

[0147] Among them, is the heuristic information between the i-th grid area and the j-th grid area, , are weight coefficients (which can be set according to actual needs);

[0148] Calculate the selection probability between each grid area according to the following formula: ;

[0149] Among them, is the selection probability between the i-th grid region and the j-th grid region (which represents the occurrence probability of the action of selecting the j-th grid region as the distribution grid after selecting the i-th grid region as the distribution grid), is the pheromone concentration between the i-th grid region and the j-th grid region (which represents the pheromone concentration of the action of selecting the j-th grid region as the distribution grid after selecting the i-th grid region as the distribution grid), is the pheromone concentration between the i-th grid region and the s-th grid region (which represents the pheromone concentration of the action of selecting the s-th grid region as the distribution grid after selecting the i-th grid region as the distribution grid), is the heuristic information between the i-th grid region and the s-th grid region (which represents the heuristic information value of the action of selecting the s-th grid region as the distribution grid after selecting the i-th grid region as the distribution grid), all represents the set of selectable grid regions (that is, the set of valid grid regions not in the second tabu list, indicating that the s-th grid region is a valid grid region not in the second tabu list, indicating that the j-th grid region is a valid grid region not in the second tabu list), is the heuristic factor (which can be preset according to actual needs), is the expected factor (which can be preset according to actual needs).

[0150] Among them, in step C5, when the new ant gradually selects and transfers the distribution grid from the valid grid regions not in the second tabu list according to the selection probability between the valid grid regions, it can adopt the roulette wheel mechanism to select the next valid grid region as the distribution grid according to the selection probability between the newly selected distribution grid (that is, the grid region where the new ant is currently located) and the valid grid regions not in the second tabu list, and transfer to the selected next valid grid region. Among them, the roulette wheel mechanism is a prior art and will not be elaborated here.

[0151] Among them, in step C6, according to the distribution grid set and the bed increment and space suitability of the target facilities corresponding to each grid region, determine the number of beds of the target facilities in each distribution grid of the distribution grid set to obtain a planning result, specifically including:

[0152] Establish an empty third tabu list;

[0153] Sort the distribution grids in the distribution grid set in descending order according to the space suitability;

[0154] According to the sorting order, each distribution grid in the distribution grid set is sequentially used as the selected distribution grid, and the following operations are performed: The valid grid areas within the influence area of the selected distribution grid that are not in the third taboo list are used as the assigned grids for the selected distribution grid;

[0155] Calculate the sum of the bed increments of the target facilities corresponding to the assigned grids of each distribution grid as the number of beds of the target facility in the corresponding distribution grid.

[0156] Among them, in step C6, the fitness value can be calculated according to the following formula: , where is the fitness value, S is the number of distribution grids in the distribution grid set, z is the total number of beds of the target facility in each distribution grid, is the average of the spatial suitability of the distribution grids in the distribution grid set, , are weight values (which can be set according to actual needs). Using this fitness value is beneficial to making the number of selected distribution grids smaller and the average spatial suitability larger. Thus, while meeting the bed increment of the target facility, the construction quantity of the target facility is reduced, which is beneficial to reducing the overall construction cost and the difficulty of land use planning, and is also beneficial to establishing the target facility at a location with better spatial suitability.

[0157] Among them, in step C6, when updating the optimal planning result, if the current obtained planning result is the first planning result corresponding to the target facility, then the current obtained planning result is used as the optimal planning result. Otherwise, compare the fitness value of the current obtained planning result with the fitness value of the current optimal planning result, and when the fitness value of the current obtained planning result is greater than the fitness value of the current optimal planning result, replace the current optimal planning result with the current obtained planning result as the new optimal planning result.

[0158] Among them, in step C7, the preset termination condition is: the number of ants released reaches the preset quantity threshold (which can be set according to actual needs), or the number of times the optimal planning result remains continuously unchanged reaches the preset number threshold (which can be set according to actual needs).

[0159] Among them, in step C7, the pheromone concentration between each grid area can be updated according to the following formula: ;

[0160] Among them, is the updated pheromone concentration between the i-th grid area and the j-th grid area, is the evaporation coefficient and (which can be preset specifically according to actual needs), is the increment of pheromone concentration between the i-th grid area and the j-th grid area. If a new ant has performed the following actions in this iteration: selecting the i-th grid area as the distribution grid and then selecting the j-th grid area as the distribution grid, then , is the pheromone increment coefficient (set according to actual needs), otherwise, is 0.

[0161] Furthermore, the selection probability between each grid area can be updated according to the following formula: ;

[0162] where is the updated selection probability between the i-th grid area and the j-th grid area, is the updated pheromone concentration between the i-th grid area and the s-th grid area.

[0163] As can be seen from the above, the method for site selection and planning of pension facilities divides the planned area into grid areas to obtain multiple grid areas; obtains the historical population information, existing pension facility information, distribution information of supporting elderly facilities, distribution information of transportation facilities, and distribution information of environmental impact facilities of the planned area; calculates the demand for pension facility beds in each grid area after a preset time according to the historical population information; calculates the target increment of pension facility beds in each grid area according to the existing pension facility information and the demand for pension facility beds; calculates the spatial suitability of each grid area according to the distribution information of supporting elderly facilities, distribution information of transportation facilities, and distribution information of environmental impact facilities; plans the distribution grid and the corresponding number of beds of new pension facilities according to the target increment of pension facility beds and the spatial suitability in each grid area; thereby improving the planning efficiency of pension facility site selection and planning and the rationality of the planning scheme.
