DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention enables efficient inventory management of emergency response parts necessary for emergency response such as when a failure occurs among various parts of equipment installed in a customer building. The present invention relates to an emergency parts inventory management device for equipment.

[0002]

2. Description of the Related Art As a related art relating to parts inventory management, there is, for example, a parts delivery instruction apparatus proposed in Japanese Patent No. 2956085. This apparatus calculates the number of order instruction cards based on information from the production planning means by a number calculating means, compares the calculated number with a preset lower limit value, and uses a part delivery lead time. Compared with the lead time, if the number of sheets calculated by the sheet number calculation means falls below the lower limit and the delivery lead time is shorter than the use lead time, the part order instruction form is changed from "Kanban instruction" to "Fixed instruction" (Delivery lead time) (Instructed before the time).

Further, Japanese Patent Application Laid-Open No. 6-2551045 discloses that the number of parts to be supplied for maintenance in a target area is determined by a self-sufficiency rate of a warehouse and a supply capacity, which is a spare capacity to lend parts between warehouses. , Evaluate the transport time between warehouses,
There has been proposed a system for allocating maintenance parts with repair, which determines the amount of parts to be allocated to each warehouse.

[0004]

The above-mentioned prior art (parts delivery instruction device) is for delivering parts from a parts factory to an assembly factory in accordance with a planned production amount. Since the means for supplying the corresponding parts is not considered, it is not possible to quickly supply the required amount of parts at the time of emergency response such as when a failure occurs, thereby causing a great deal of inconvenience to the customer and reducing trust. There is a risk that it will.

[0005] On the other hand, the latter prior art (deployment system of maintenance parts with repair) is for determining the amount of parts to be distributed to each base warehouse. Since the means for specifying the parts is not taken into account, the supply of the necessary parts is likely to be hindered in an emergency response. In addition, in the case of this conventional technique, a large number of parts must be deployed in the base warehouse, so that a large storage space must be secured in the warehouse, and therefore, there is a problem that logistics costs such as warehouse management costs increase. Was.

[0006] The present invention has been made in view of such problems of the prior art, and an object of the present invention is to store emergency response parts in warehouses at each base without excess or deficiency, thereby controlling logistics costs while maintaining an emergency. It is an object of the present invention to provide an emergency parts inventory management device for equipment which enables quick supply of parts at the time of response.

[0007]

In order to achieve the above-mentioned object, an emergency parts inventory management apparatus according to the present invention provides an emergency parts inventory management apparatus for an equipment part installed in each of a plurality of customer buildings. Emergency part determination rule storage means for storing a determination rule serving as a guideline for determining the importance of the part at the time of handling, failure information and operation information of the equipment, component arrangement information at the time of failure occurrence, and the determination rule From the above, the importance evaluation rank determining means for determining the importance evaluation rank at the time of emergency response of the component, and the emergency required at the time of emergency response from the parts ranked by the importance evaluation rank determination means Emergency parts identification means for selecting the corresponding parts, and calculating the minimum required amount for each base in deploying the emergency corresponding parts in a plurality of base warehouses, respectively. It was decided and a fast component deployed amount calculating means.

The emergency parts inventory management device having such a configuration identifies an emergency response component based on various history information and a predetermined determination rule, and then determines the amount of the emergency response component that is not excessive or insufficient for each base warehouse. Therefore, necessary parts can be promptly supplied at the time of emergency response such as when a failure occurs. Moreover, since the amount of emergency response parts to be deployed at each base warehouse is minimized, storage space can be saved and logistics costs such as warehouse management costs can be reduced.

[0009] In addition to the above configuration, if the emergency parts inventory management device is provided with setting means for resetting the importance evaluation rank and the emergency response parts at predetermined intervals, the operation status of the facility equipment can be reduced. Since it is possible to appropriately consider the contents of the failure and the aging of the parts that change according to the situation, it is possible to always accurately specify the emergency response parts and calculate the amount of the parts to be deployed, thereby improving the reliability.

This indicates that "50 occurrences" occurred each year. Further, it indicates that the manufacturing number of the target equipment is “T110” and the operating years thereof are “10 years”.

As described above, in this embodiment, the equipment 6
The first maintenance parts are divided into emergency response parts that are indispensable for emergency response such as when a failure occurs and other normal parts, and the emergency response parts are in excess or shortage in the parts warehouse 4 around the equipment 61. And deploying a certain amount,
On the other hand, the normal parts are not deployed in the warehouse, but are directly delivered from the parts manufacturer 5 to the sales office 7 and the customer building 6. Therefore, when a failure or the like occurs in the equipment 61, emergency parts can be promptly supplied, and it is possible to minimize inconvenience to the user. In addition, the amount of emergency response parts to be deployed in the warehouse is set to the minimum necessary, and since parts are not normally stored in the warehouse, storage space in the warehouse can be saved and warehouse management costs and other expenses can be reduced. Distribution costs can be reduced.

Next, the operation procedure of the emergency parts inventory management device 1 will be described with reference to FIG. Now, the sorting instruction to select emergency response parts has been issued by the parts management department 3.
, The emergency parts inventory management device 1 receives the sorting command through the input / output device 17 and performs the following processing in the parts information processing unit 15.

First, in step S1, the component information processing unit 15
When extracting information necessary for setting the importance evaluation rank from the failure daily report information 21, the operation information 22, and the parts arrangement information 23, the target period (the determination period) is determined by the emergency parts determination rule storage unit. Read from # 12. The determination period is a period retroactive from the time when a new importance evaluation rank is set or reviewed, for example, in the past five years.

In the next step S2, the component information processing unit 15
Reads various data within the corresponding determination period from the failure daily report information 21. At this time, by searching the “year / month / day” data stored in the failure daily report information 21, it is possible to read out the details of the failure of the component that occurred during the determination period.

In the next step S3, the component information processing unit 15
Reads various data relating to the equipment stored in the operation information 22 using the "serial number" data of the failure daily report information 21 previously read in step S2 as a search key.

In the next step S4, the component information processing unit 15
Reads various data generated during the corresponding determination period from the parts arrangement information 23. Also at this time, parts arrangement information 2
3 is used as a search key.

The part information processing unit 15 determines whether the
After processing the various data read out in 2 to S4, the data is stored in the determination information storage unit 16. FIG. 9 described above shows an example of data thus stored in the determination information storage unit 16.

In the next step S5, the part information processing section 15 retrieves "determination rule 1" from the emergency part determination rule storage section 12. The “judgment rule 1” is, for example, a rule that “the number of occurrences in the same branch office in the past five years is 50 or more, and the top 100 rankings are ranked A”.

Thereafter, in step S6, the component information processing unit 15 determines the importance evaluation rank in accordance with the "determination rule 1", and, for the components that have been ranked as emergency response components, compares the result with the emergency component Information storage unit 13
To be stored. FIG. 6 described above shows the items of the stored data at this time. In addition, for the normal parts that are not ranked as emergency response parts in step S6, the result is stored in the normal part information storage unit 14. FIG. 7 described above shows the items of the stored data at this time. However, sales office 7 that delivers parts
The information on the customer building 6 and the information on the delivery date and the delivery amount are input from the parts management section 3 as necessary, and the information is sent to the parts manufacturer 5 and the delivery company 8 via the communication device 11. Sent.

In the next step S7, the parts information processing section 15
Determines whether the determination work according to all the determination rules stored in the emergency part determination rule storage unit 12 has been completed, and if completed, proceeds to step S9, but if not completed, proceeds to step S8. Transition.

In step S8, the part information processing unit 15 takes out the next determination rule and returns to step S6, performs a process of determining the importance evaluation rank according to the determination rule, and stores the result in the emergency part information storage unit 13. Update data. Thus, the procedure of returning from step S7 to step S6 through step S8 is repeated until the determination work according to all the determination rules is completed.

As a judgment rule other than the "judgment rule 1", for example, a rule "a part having a long delivery time and a long time to recover is set to rank A" may be set as a "judgment rule 2", "Rule 3"
A component that has only occurred once but is likely to occur in the future in consideration of the number of years of operation and life is set to B rank ", or as a" judgment rule 4 " Even if there is no occurrence in the past five years and the number of operating vehicles is 100 or less, it will not be ranked A or B. " In addition, it is preferable to set a determination rule for the amount of emergency response parts to be placed in the warehouse. For example, as “determination rule n”, “a condition that the same model as that at the time of failure and the operating life is 10 years or more is satisfied. In this case, based on the ratio between the number of operating units and the number of failure occurrences, the deployment amount calculated under the same conditions over the next five years under the same conditions is set to the maximum value. "

In this way, when the determination operation according to all the determination rules is completed, and the process proceeds to step S9, a final decision is made as to how many emergency response parts are to be deployed in which warehouse.

In the next step S10, the component information processing unit 15 checks whether or not a predetermined number of years (for example, one year) has elapsed since the ranking of the importance evaluation and the setting of the deployment amount are performed. If the predetermined number of years has elapsed, the process shifts to step S11, and inquires of the parts management section 3 about whether or not to review the determination rule or the determination period. If the answer input from the parts management section 3 is "do not review", the process proceeds to step S1, and a new importance evaluation rank setting process (steps S1 to S9) is executed. If the answer input from the parts management section 3 is “review”, the process of setting the importance evaluation rank is ended.
