The terminal 102 can send the life information of each device in the set of devices to be selected to the server 104. After receiving the life information of each device in the set of devices to be selected, the server 104 calculates the important residual value and the total residual value of each device according to the life information of each device, respectively, to obtain a set of important residual values and a set of total residual values. Through a device selection method, a preset number of devices are selected from the set of devices to be selected based on the set of important residual values and the set of total residual values. The device selection method includes an exhausted use device selection method and a daily use device selection method. The server 104 can feed back the selected devices to the terminal 102. In addition, in some embodiments, the device use selection method based on life information can also be implemented by the server 104 or the terminal 102 alone, for example, the terminal 102 can directly perform device selection processing on the life information of each device in the set of devices to be selected, or the server 104 can obtain the life information of each device in the set of devices to be selected from the data storage system and perform device selection processing on the life information of each device in the set of devices to be selected.

[0028] The terminal 102 can be, but is not limited to, various desktop computers, notebook computers, smart phones, tablet computers, Internet of Things devices and portable wearable devices. The server 104 can be implemented by an independent server or a server cluster composed of multiple servers, and can also be a cloud server.

[0029] In an exemplary embodiment, as shown in Figure 2 A device use selection method based on life information is provided. The method is executed by a computer device, which can be executed by a terminal or a server alone, or by a terminal and a server together. In the embodiments of the present application, the method is applied to the server 104 in Figure 1 The following steps 201 to 203 are included. Among them:

[0030] Step 201, obtaining the life information of each device in the set of devices to be selected; the life information includes key life information and non-key life information. The life information includesM One of the life information is important, usually this M One of the life information is important, usually this N One of the life information is important, usually this

[0031] Step 202, according to the life information of each device, the important remaining value and the total remaining value of each device are calculated respectively, and the important remaining value set and the total remaining value set are obtained.

[0032] Step 203, through the device selection method, based on the important remaining value set and the total remaining value set, a preset number of devices are selected from the set of devices to be selected; the device selection method includes the exhausted use device selection method and the daily use device selection method.

[0033] The above steps 201 to 203 are implemented, and the application can get rid of the excessive dependence on artificial experience in traditional device use selection, and scientifically evaluate the remaining value of the device based on objective and quantitative life information. By accurately calculating the important remaining value and the total remaining value, the value status of the device in different dimensions can be comprehensively measured, and reliable basis is provided for subsequent device selection. Based on the reasonable construction of the remaining value set, the targeted device selection method is used, whether it is daily use or exhausted use, the most suitable device can be selected, the value waste caused by unreasonable use of the device is effectively avoided, the overall use efficiency of the device is improved, the enterprise device management cost is reduced, and the production benefit is improved.

[0034] In another exemplary embodiment of the application, the important remaining value of the device is calculated according to the life information of the device, specifically including:

[0035] .

[0036] Among them, The important remaining value of the device is represented; The consumption value of the first m Key life information of the device is represented; The limit value of the first m Key life information of the device is represented; M The total number of key life information of the device is represented.

[0037] In another exemplary embodiment of the application, the total remaining value of the device is calculated according to the life information of the device, specifically including:

[0038] .

[0039] Among them, total remaining value of the device; consumption value of the first m key life information of the device; limit value of the first m key life information of the device; M total number of the key life information of the device; consumption value of the first n non-key life information of the device; limit value of the first n non-key life information of the device; N total number of the non-key life information of the device.

[0040] In another exemplary embodiment of the present application, when the device selection method in step 203 is the depletion-type device selection method, a preset number of devices are selected from the device set to be selected based on the important remaining value set and the total remaining value set, and the method specifically comprises:

[0041] devices in the device set to be selected that cannot meet daily use are selected as primary devices to obtain a primary device set; the devices that cannot meet daily use are devices whose life value of at least one life information is less than a preset minimum requirement threshold of a daily use device.

[0042] If the number of devices in the primary device set is greater than or equal to the preset number of devices to be selected, the preset number of devices to be selected are selected according to a preset selection rule; the preset selection rule is to determine whether the life information of the device to be selected contains time-varying loss type life information; if the result is yes, the preset number of devices to be selected are selected in descending order of the remaining value of the time-varying loss type life information; if the result is no, the preset number of devices to be selected are selected in descending order of the total remaining value; if the remaining value of the time-varying loss type life information or the total remaining value of the device is the same, the devices are selected in descending order of the important remaining value of the device; if the remaining value of the time-varying loss type life information or the total remaining value of the device is the same, and the important remaining value is the same, the devices are selected randomly; the time-varying loss type life information is life information that automatically decreases with time.

[0043] If the number of devices in the primary device set is less than the preset number of devices to be selected, devices in the remaining devices in the device set to be selected except the primary devices and whose time-varying loss type life information is less than the next depletion-type use time in an annual plan are selected as secondary devices to obtain a secondary device set; the annual plan is a time schedule prepared in advance according to the device use requirement.

[0044] If the number of devices in the secondary selection set is greater than or equal to the second number, then the second number of devices is selected according to the preset selection rules; the second number is the preset selection number minus the number of primary devices.

[0045] If the number of devices in the secondary selection set is less than the second number, then a third number of devices are selected from the remaining devices in the selection set excluding the primary and secondary selection devices, according to a preset selection rule; the third number is obtained by subtracting the number of primary devices from the preset selection number, and then subtracting the number of secondary selection devices.

[0046] As an optional implementation, p devices are provided, and this exhaustive usage requires... l ( l≤ p) equipment. The equipment to be used in exhaustion mode shall be selected in the following order until the number of selected equipment meets the needs of this exhaustion mode.

[0047] (1) Preferred Equipment. First, select equipment that cannot meet daily use requirements. If this type of equipment has time-varying loss type lifetime information (let this lifetime information be Z) that automatically decreases over time, and the number of equipment that cannot meet daily use requirements is greater than [a certain threshold]. l Then, among the devices that cannot meet daily use requirements, they are selected from smallest to largest based on the remaining lifespan information Z. l For a given number of devices with the same remaining lifespan information Z, selection is made in ascending order of remaining value. If such devices do not have lifespan information indicating an automatic decrease in lifespan over time, and the number of devices unable to meet daily usage requirements is greater than [a certain threshold], then [further selection is made]. l Then, among the devices that cannot meet daily needs, select them in ascending order of their remaining value. l For equipment with the same residual value, selection should be made based on the residual value of the equipment from lowest to highest importance. If the number of devices that cannot meet daily usage is less than [number missing], [further details needed]. l Select all devices that cannot meet daily usage needs for this exhaustive testing, then continue selecting from the secondary and final selection devices. If the number of devices that cannot meet daily usage needs is equal to... l Select all devices that cannot meet daily use requirements for this exhaustion-style use; device selection complete.

[0048] (2) Secondary equipment. Determine the appropriate equipment type. If any time-varying loss type of lifespan information exists within the lifespan information, automatically decreasing over time, and if such lifespan information exists, and this type of lifespan does not last until the next depletion-type use time in the annual work plan, then this part of the equipment will be selected as the second batch of equipment. This part of the equipment will be selected according to the remaining lifespan of this type from smallest to largest. For equipment with the same remaining value, selection will be based on the remaining value of the equipment from smallest to largest.

[0049] (3) Final Equipment Selection. The remaining equipment after the first and second choices is sorted by residual value from smallest to largest, and then the equipment is selected in ascending order to meet the exhaustion-type usage requirements. For equipment with the same residual value, selection is based on the most important residual value from smallest to largest. If two pieces of equipment have the same residual value and primary residual value, one of these two pieces of equipment is randomly selected.

[0050] In another exemplary embodiment of this application, when the device selection method in step 203 is a method for selecting devices used daily, a preset number of devices are selected from the set of devices to be selected based on the important residual value set and the total residual value set, specifically including:

[0051] Devices in the set of devices to be selected whose remaining lifespan after the current daily use is insufficient to meet the requirements of exhaustive use are classified as Class A devices, thus obtaining the Class A device set.

[0052] The remaining devices in the set of devices to be selected, excluding those in category A, are designated as category B devices, thus obtaining the set of category B devices.

[0053] A preset number of candidate devices are selected from the B-type device set according to a preset selection rule to obtain an intermediate device set; the preset number of candidate devices is greater than the preset number of selected devices.

[0054] Calculate the minimum service life value for all life types of each device in the intermediate device set.

[0055] In the intermediate equipment set, select a preset number of equipment based on their minimum service life value, from smallest to largest.

[0056] The methods for selecting equipment in daily use mainly achieve the following objectives.

[0057] First, the equipment The lifespan of the equipment is used in a relatively balanced manner to avoid situations where one type of equipment is about to reach the end of its lifespan while other types of equipment still have a long lifespan ahead of them.

[0058] Second, to ensure the depletion of reserve equipment, it avoids the waste of equipment lifespan information caused by the remaining value of all equipment being high during depletion.

[0059] As an optional implementation, there are a devices. The current daily use requires b (b≤a) devices, and the next exhaustive use is expected to require c devices. The method for selecting devices for daily use is as follows.

[0060] (1) Find and count the equipment that will not be able to participate in the exhaustion use after this daily use. The remaining lifespan of the equipment cannot meet the exhaustion use. For the convenience of description, this type of equipment is called Class A equipment, and the quantity of this type of equipment is d.

[0062] (3) excluding the A-type devices from the a devices, for the convenience of expression, the remaining devices are called B-type devices. The residual value of the B-type devices is calculated, and e devices are selected in the order from small to large. In the B-type devices, e devices with small residual value are selected, and then devices with small usage are selected from the e devices, so as to reserve devices for the exhausted use. If the devices with small usage are directly selected from the B-type devices, the device life will be wasted in the exhausted use.

[0063] (4) judging whether there is time-varying loss type life information in the life of the device , if there is such life, assuming that there are J kinds of such life, one kind of life is selected from the life , the minimum usage life value of all kinds of life of each device is calculated , wherein i is an integer in [1, e].

[0064] if there is no time-varying loss type life in the life of the device, the minimum usage life value of all kinds of life of each device is calculated .

[0065] (5) the e devices are sorted according to the value from small to large, and then b devices are selected according to the value from small to large for the daily use.

[0066] In another exemplary embodiment of the present application, the minimum usage life value of all kinds of life of each device in the intermediate device set is calculated, which specifically includes:

[0067] if the life information of the device to be selected contains time-varying loss type life information, the minimum usage life value of all kinds of life of each device is calculated by the following formula:

[0068] .

[0069] wherein, indicates the first i ​​​a minimum service life value of all life categories of the device; i ={1,2,...,e};e represents a preset candidate number; represents a consumption value of the first j time-varying loss type life information of the device, j ={1,2,...,J},J represents a total number of time-varying loss type life information;the first j time-varying loss type life information is any one of all time-varying loss type life information of the device; represents a limit value of the first j time-varying loss type life information of the device; represents a consumption value of the first life information of the device; represents a limit value of the first life information of the device; represents a total number of life information of the device; M represents a total number of key life information of the device; N represents a total number of non-key life information of the device.

[0070] If the life information of the device to be selected does not contain time-varying loss type life information, a minimum service life value of all life categories of each device is calculated by the following formula:

[0071]

[0072] In another exemplary embodiment of the present application, a certain type of device has two life information of service times and storage life, and has two service methods of daily use and depletion use. The maximum service times of the device is X 1, and the storage life is years. The maximum service times is key life information, and the storage life is non-key life information. The total number of life information is 2, and the total number of key life information is M 1. If a certain device of this type has been used times and has been stored for years, the important residual value of the device is:

If a<0.1I, select a devices of this type for this time depletion usage, and then go to (2); otherwise, from the a devices, select m devices according to the remaining storage life from small to large, go to (4). m
