1-4. Operation of Maintenance Contract Plan Determination Support System 100 Next, specific processing of the usage behavior calculation process, evaluation result calculation process, and contract plan selection process executed in the maintenance contract plan determination support system 100 will be described.

FIG. 4 is a diagram for explaining the usage behavior calculation process of the first embodiment. In the example shown in this figure, the human sensor 4 is installed on the ceiling of a passageway in the target facility where the elevator 2 is installed. When a facility user enters the detection area of the human sensor 4 at time t1, the detection signal of the human sensor 4 is switched from OFF to ON. Then, when the facility user moves within the detection area and moves out of the detection area at time t2, the detection signal of the human sensor 4 switches from ON to OFF. In the following description, the period during which the detection signal of the human sensor 4 is ON, ie, the time (t2-t1), will be referred to as the "stay time" of the facility user in the detection area. Such human sensors 4 are installed at multiple locations within the target facility. The detection signal of each human sensor 4 is stored in the equipment data storage unit 204 as equipment data after being associated with the time of detection.

FIG. 5 is a flowchart showing the routine of the usage behavior calculation process executed by the control device 12. Hereinafter, with reference to the flowchart shown in FIG. 5, a method in which the control device 12 calculates usage behavior through usage behavior calculation processing will be described. In step S100 of the routine shown in FIG. 5, a usage behavior calculation rule is acquired from the calculation rule storage unit 205. The calculation rules here include the equipment data acquisition period, usage behavior calculation method, and the like. When the process of step S100 is completed, the process proceeds to step S102.

In step S102, equipment data for a certain period of time in the past is acquired from the elevator 2 according to the acquired calculation rule. The equipment data includes detection signals of all installed human sensors 4 and their detection times. The past fixed period here is, for example, the past one month. The acquired equipment data is stored in the equipment data storage section 204. When the process of step S102 is completed, the process advances to step S104.

In step S104, it is determined whether calculation of usage behavior has been completed in all detection areas. The detection area here is a detection area assigned to each human sensor 4. In the first step S104, the usage behavior has not been calculated yet, so the process proceeds to step S106.

In step S106, a detection area is selected. Here, one of the detection areas whose usage behavior has not yet been calculated is selected. When the process of step S106 is completed, the process advances to step S108.

In step S108, usage behavior is calculated from the equipment data of the detection area selected in step S106 according to the acquired calculation rule. Here, first, the stay time is calculated from each of the equipment data of the selected detection area. Next, the obtained residence time distribution is fitted to the Weibull distribution, and parameters α and β of the probability density function shown in equation (1) are determined.

In step S108, the standard stay time corresponding to the selected detection area is read. The standard stay time here is a standard value of the time that a facility user in a normal state who is not in a hurry stays in the detection area, and is a predetermined value. Next, using the Weibull distribution, a hazard function representing the probability of movement out of the detection area after time t has elapsed is calculated. The hazard function is shown in equation (2). The standard sojourn time is given to the hazard function, and the probability of moving out of the detection area when the standard sojourn time has elapsed is calculated. The calculated movement probability is stored in the usage behavior data storage unit 206 as a usage behavior index value for the detection area.

When the process of step S108 is completed, the process proceeds to step S104 again. Then, by repeatedly executing the processes from step S104 to step S108, usage behavior is calculated for all detection areas, and this routine ends.

Next, with reference to the flowchart of FIG. 6, a procedure in which the control device 12 evaluates usage behavior through usage behavior evaluation processing and a procedure in which a maintenance contract plan is selected through contract plan selection processing will be described. FIG. 6 is a flowchart showing a routine of usage behavior evaluation processing and contract plan selection processing executed by the control device 12. In step S120 of the routine shown in FIG. 6, an evaluation rule is acquired from the evaluation rule storage unit 207. The evaluation rules here include evaluation methods for usage behavior. When the process of step S120 is completed, the process proceeds to step S122.

In step S122, it is determined whether evaluation of usage behavior has been completed in all detection areas. In the first step S122, the usage behavior has not been evaluated yet, so the process proceeds to step S124.

In step S124, a detection area to be evaluated is selected. Here, one of the detection areas whose usage behavior has not yet been evaluated is selected. When the process of step S124 is completed, the process proceeds to step S126.

In step S126, first, the movement probability of the selected detection area is read from the usage behavior data storage unit 206. The movement probability statistically indicates that the higher the probability value, the greater the proportion of facility users who passed through the detection area in a hurry. Facility users' usage behavior when they are in a hurry is likely to be more sloppy than when they are not. In other words, it can be said that the movement probability is a value that can be used as an index for determining the superiority or inferiority of the usage behavior of facility users. Therefore, the evaluation rules define the relationship between movement probability and the superiority or inferiority of usage behavior. For example, a first range with a low probability of movement is associated with rank A, where the usage behavior is excellent, and a second range, which is higher than the first range, is associated with rank B, where the usage behavior is average. A third range higher than the second range is associated with rank C, which indicates bad usage behavior. The first range, the second range, and the third range are examples of evaluation criteria for ranking the superiority or inferiority of usage behavior. There are no limitations on the number of ranks and the range of ranks.

In step S126, according to the acquired evaluation rule, it is determined to which range of the first range, second range, or third range the movement probability of the detection area selected in step S124 belongs. Then, a rank corresponding to the determination result is calculated as the evaluation result. The calculated evaluation results are stored in the evaluation result data storage section 208.

When the process of step S126 is completed, the process proceeds to step S122 again. Then, by repeatedly executing the processes from step S122 to step S126, usage behavior is evaluated for all detection areas, and the process proceeds to step S128. In this way, steps S120 to S126 are steps for executing the usage behavior evaluation process.

Step S128 is a step of executing contract plan selection processing. In step S128, a maintenance contract plan is selected based on the evaluation result. The contract plan storage unit 209 stores a plurality of maintenance contract plans corresponding to the superiority and inferiority of usage behavior. The plurality of contract plans have different standards for calculating maintenance fees. Here, one of the plurality of maintenance contract plans stored in the contract plan storage section 209 is selected based on the evaluation results corresponding to each detection area. There is no limitation on the method of selecting a maintenance contract plan, as long as it is selected so that the better the usage behavior is, the greater the benefit to the maintenance contractor regarding the maintenance fee will be. When the process of step S128 is completed, this routine is ended.

According to the usage behavior calculation process as described above, it is possible to calculate the movement probability as the usage behavior index value for all detection areas within the target facility. Further, according to the usage behavior evaluation process, it is possible to evaluate whether the usage behavior of facility users is good or not, and to reflect this in the selection of a maintenance contract plan. As a result, it is possible to increase the level of satisfaction with maintenance fees among maintenance contractors of target facilities with excellent usage behavior.

2. Embodiment 2.
Features of the maintenance contract plan decision support system according to the second embodiment FIG. 7 is a diagram for explaining the overall configuration of the maintenance contract plan decision support system according to the second embodiment. The maintenance contract plan decision support system 200 of the second embodiment includes, in addition to the maintenance contract plan decision support system 100 of the first embodiment, an entry/exit history acquisition device 5 at the entrance of the target facility. The entry/exit history acquisition device 5 is a device for obtaining a history of entry/exit to the floor area where the platform 2a of the elevator 2 of the target facility is installed. The entry/exit history acquisition device 5 stores entry/exit history information in which the time of entry/exit is associated with the ID information by reading the ID information of the facility user.

The room entry/exit history acquisition device 5 is connected to the maintenance contract plan decision support device 10 via the network 6. The entry/exit history information acquired by the entry/exit history acquisition device 5 is taken into the maintenance contract plan decision support device 10 using the communication device 18 and stored in the equipment data storage unit 204 as part of the equipment data.

Additionally, the data acquisition unit 141 acquires the operation history of the elevator 2 as part of the equipment data, and stores it in the equipment data storage unit 204. The operation history here includes information on the time when the car arrived by registering a hall call from the platform 2a of the elevator 2.

The maintenance contract plan decision support device 10 further uses the entry/exit history information and the operation history in the usage behavior calculation process. Typically, in step S108 of the usage behavior calculation process shown in FIG. 5, the operation history of the elevator 2 is acquired, and from the acquired operation history, the arrival time when the car arrived at the platform 2a by registering a platform call from the platform 2a. is read out. Next, assuming that the facility user who registered the platform call from platform 2a is the facility user who entered the floor area immediately before, the facility user's entry time is determined from the previous entry/exit history information. is obtained. The time from the acquired entry time to the arrival time when the car arrives corresponds to the travel time from when the facility user using the elevator 2 enters the floor area until when he gets on the elevator 2. Therefore, limited to this travel time, a hazard function representing the movement probability of moving out of the detection area when the standard stay time has elapsed is calculated using the Weibull distribution and the standard stay time. The calculated movement probability is stored in the usage behavior data storage unit 206 as an index value of the usage behavior of the detection area.

According to the above-described operation, the usage behavior is calculated by dividing only the time period related to the movement of the facility user who uses the elevator 2. This deepens the relationship between the calculated usage behavior and the usage behavior of the elevator 2, so that the usage behavior of the elevator 2 can be grasped more accurately.

3. Modifications of this Embodiment The maintenance contract plan decision support system 100 of this embodiment may be modified as follows.

3-1. Weibull Distribution The method of calculating the usage behavior from the equipment data of the detection area is not limited to the method using the Weibull distribution, but may also use other known probability density functions.

3-2. Maintenance contract plan change timing The maintenance contract plan selection support system 100 may select a maintenance contract plan at the request of the maintenance contractor, or may select the maintenance contract plan periodically, such as every predetermined period or at the time of contract renewal. may be executed. Alternatively, if there is a change in tenants within the target facility, there is a possibility that the usage behavior of facility users will change. Therefore, the maintenance contract plan decision support system 100 executes the usage behavior evaluation process when the usage behavior for a certain period in the past has changed from the standard value from the usage behavior for a period longer than the certain period in the past. You may also want to re-evaluate your usage behavior. The reference value here is a threshold value for determining the degree of change in usage behavior, and a predetermined value is used. Further, in this case, the maintenance contract plan decision support system 100 may execute a notification process in the notification unit of the processor 14 to notify the maintenance contractor that the usage behavior has changed. There are no restrictions on the form of notification. According to such an operation, the maintenance contract plan can be changed at a more appropriate timing.

3-3. Usage behavior evaluation processing The evaluation method using usage behavior evaluation processing not only ranks each target facility based on absolute evaluation criteria, but also ranks based on relative comparison with usage behavior of other target facilities. Good too. In this case, in the usage behavior evaluation process, the usage behavior evaluation unit 146 further calculates a ranking result that ranks the superiority or inferiority of usage behavior between the target facility and other facilities based on the usage behavior index value. Then, the contract plan selection unit selects a maintenance contract plan based on the evaluation results and ranking results in the contract plan selection process. According to such an operation, for example, even if the target facilities are classified into evaluations of the same rank, different contract plans can be selected in consideration of the ranking. This allows a more detailed maintenance contract plan to be determined.

3-4. Usage Behavior Evaluation Process and Contract Plan Selection Process Usage behavior may change to the advantageous side, such as when the equipment of the elevator 2 in the target facility is replaced or monitoring is strengthened through an option contract. In such a case, it may be determined that the real estate value of the target facility has improved, and the usage behavior evaluation process may be executed to re-evaluate the usage behavior. Furthermore, in the contract plan selection process, in addition to the evaluation results of usage behavior, the contribution to the improvement of real estate value may be considered. In this case, for example, if the usage behavior changes to the favorable side, the usage behavior evaluation unit 146 calculates the degree of contribution of the target facility to the real estate value in the usage behavior evaluation process. Such a degree of contribution may be estimated by comparing, for example, the amount of reduction in management costs, the reduction in the number of complaints, the maintenance period of the interior of the target facility, etc. with the actual results at other facilities. Then, in the contract plan selection process, the contract plan selection unit 147 selects a maintenance contract plan based on the evaluation result and the degree of contribution. According to such an operation, it becomes possible to determine a maintenance contract plan that takes into account the degree of contribution of real estate value.

3-5. Example of multiple usage behaviors If multiple usage behaviors are calculated in a common detection area in the usage behavior calculation process, the evaluation results of each of the multiple usage behaviors are calculated in the usage behavior evaluation process, and the A final evaluation result may be calculated from the evaluation results. For example, when a vibration sensor is provided on the door of an elevator serving as the elevator 2, the evaluation result is calculated using the number of vibrations at which the vibration sensor detects vibrations greater than a reference value as the usage behavior index value. Furthermore, the evaluation result is calculated using the movement probability calculated from the stay time in the detection area including the door of the elevator as the elevator 2 as the usage behavior index value. Each evaluation result here may be ranked based on evaluation criteria or may be ranked based on relative comparison with usage behavior of other target facilities. When the evaluation results are ranked, for example, the ranking obtained by adding these two evaluation results is used as the final evaluation result. Alternatively, if the evaluation result is a ranking, for example, an intermediate value between the ranks of these two evaluation results is used as the final evaluation result. According to such an operation, the accuracy of evaluation of usage behavior increases, so that a more optimal maintenance contract plan can be determined.

3-6. Examples of Other Usage Behaviors The usage behavior of facility users is not limited to the stay time within the detection area calculated from the detection signal of the human sensor 4. That is, as long as the behavior can determine the superiority or inferiority of the use of the target facility, it may be only the number of vibrations detected by the vibration sensor described above, or it may be the usage behavior shown in the table of FIG. 8, for example. FIG. 8 shows modified examples of usage behavior, examples of each usage behavior, and related data that can be used to detect usage behavior.

In the example shown in FIG. 9, the control device 12 includes a processing circuit 17 including, for example, a processor 14, a memory 16, and dedicated hardware 15. FIG. 9 shows an example in which some of the functions of the control device 12 are realized by dedicated hardware 15.
