Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plan making apparatus, a plan making method for making a plan for construction and maintenance of equipment provided in a factory or a plant, a plan making method, and a program for realizing these with a computer. The present invention relates to a computer-readable recording medium storing the program.

[0002]

2. Description of the Related Art In a factory or a plant of a manufacturing industry, an execution plan for repair work or maintenance work for operating equipment is made.
Based on the plan, necessary materials and equipment will be procured and actual renovation and maintenance work will be performed. For example, if the equipment needs to be replaced regularly, the replacement work is incorporated in the annual plan. Hereinafter, factories and plants are collectively referred to simply as "factories", and repair work and maintenance works are collectively referred to as "constructions". In addition, the execution plan and the like related to this construction will be simply referred to as “plan” unless otherwise specified.

[0003] In a factory, an appropriate construction period is set based on the convenience of the factory, such as a production operation plan and a shipping schedule, or a recommended replacement time of equipment and materials, and a construction plan is created. In addition, when preparing this construction plan, it is necessary to arrange materials and equipment necessary for the construction work. A procurement plan is also prepared.

FIG. 5 is a diagram showing an example of a construction plan created in a factory. In FIG. 5, the horizontal axis represents time.
In FIG. 5, six (6) works are planned for the facilities 1 to 5 at the factory: construction (a), construction (a), construction (c), construction (d), construction (e), and construction (f). ing. For example, in the construction (a), three materials A and two B are required during the period from the scheduled construction start 60 to the scheduled construction end 61. Since it is known that it takes several days for delivery from ordering to delivery of both A-item and B-item, ordering of the equipment and materials to the equipment and equipment maker on the equipment and equipment order date 62 prior to the start of the construction (A) Is supposed to.

Similarly, in the construction (a), the construction (c), the construction (d), the construction (e), and the construction (f),
The materials and equipment required for each construction work will be ordered in consideration of the delivery date. Materials A required for construction (A) are also required for construction (A), construction (C), construction (D),
Two materials B are required in the construction (a).

On the other hand, a material and equipment maker that receives an order for the material and equipment receives an order for the construction (a) from the factory or receives an estimate request from the factory in advance. The material maker sets the unit prices of the A and B products for the factory based on the order or the quote request, and starts production of the material in accordance with the delivery date.

By the way, in the manufacturing industry, it is not rare that the production line for producing a plurality of products is set up on the same line, and the setting of the production line is changed according to the products to be produced. In the case of such a method, the production line must be stopped by changing the setting itself, or the stability of the product quality may decrease immediately after the setting change, which may cause a decrease in productivity. Generally, in many cases, productivity is improved by producing a large number of products at one time, and as a result, the selling price is often reduced.

[0008]

However, as described above, regardless of the production schedule of the equipment manufacturer, the factory simply determines the necessary time of the equipment based on its own plan and places an order. Therefore, the equipment manufacturer had no choice but to produce the necessary equipment based on it. vice versa,
The factory had no choice but to place orders based on the price of the equipment, which fluctuated depending on the circumstances of the equipment manufacturer.

[0009] Therefore, for example, if the factory side consolidates all the equipment and materials required for the construction based on the annual construction plan and needs a plurality of the same equipment and materials, the factory side purchases the equipment and materials at the beginning of the year. As a result, the purchase unit price may be reduced. However, purchasing materials and equipment in bulk at the beginning of the year can reduce the purchase price of the equipment and materials, but can be used to store the delivered equipment and materials that require temperature control as a storage method. Due to the high maintenance costs, physical disadvantages such as storage location and management method occurred, resulting in inefficiency in the end.

[0010] On the other hand, from the viewpoint of the equipment manufacturer, the partner factory is not always one company, and the equipment and materials are ordered from a plurality of factories and production is performed. The production of the same products ordered from different factories is improved collectively, thereby reducing the number of changes to production line settings and improving productivity.However, there is no way to collectively receive orders from these multiple factories. We had orders separately.

As described above, in the past, from the factory side, since the order was placed based on its own construction plan, it was necessary to purchase materials and equipment that could be purchased at a lower price at a higher price. In addition, the equipment manufacturers also cannot efficiently produce products in terms of production cost and production time due to small orders from factories, resulting in higher production costs for equipment and equipment, which has a negative impact on the factory. Was exerted.

Accordingly, the present invention provides a construction plan capable of creating a construction plan so that a factory can purchase materials and equipment at a low price by ordering multiple lots while shortening the stock period of the equipment and materials as much as possible. It is an object to provide a creation device.

DESCRIPTION OF THE PREFERRED EMBODIMENTS (First Embodiment) An embodiment of the present invention will be described below with reference to the drawings. FIG.
It is a figure showing the example of composition of the plan creation device by a 1st embodiment of the present invention. In this embodiment, in one company, there is a factory 2 which is an operation facility, a maintenance department 1 for constructing the factory 2, and a purchasing department 3 for purchasing materials and equipment. An example will be described in which the device 10 is used.

The plan creation device 10 includes a construction plan creation unit 1
1, a material / material management unit 12, a display / output unit 13, a central processing unit 14, a factory equipment database 15, a construction plan database 16, a material / database 17, an input unit 18, and the like. These are mounted on a computer, and may be connected to another computer used in the factory 2 or the purchasing department 3 via the network 4.

The maintenance department 1 prepares a construction plan based on the maintenance standards of the factory 2 of the company and the occurrence status of defects, and based on the plan, procure materials and equipment or actually performs the construction. Therefore, the maintenance plan 1 firstly constructs the construction plan 11
In order to create a construction plan, the construction plan creation unit 1 uses a keyboard and a pointing device of the input unit 18.
1 is instructed to start. At this time, construction plan database 1
If a construction plan is to be created by modifying the construction plan already stored in 6, a predetermined plan is extracted from the construction plan database 16.

Next, equipment design drawings, specifications, maintenance histories, and the like are read from the factory equipment database 15. Based on these data, a plan is set, for example, replacing the power supply, the pump, the pipe for piping, etc. with a new one, or installing a new facility. Alternatively, inspection work and the like may be included in the plan. Although not shown, the progress may be confirmed by a construction progress management unit or the like and reflected in the construction plan.

Next, when the construction plan is created, what kind of equipment and materials are required for each construction is extracted. For example, as shown in FIG.
Three products and two B products are required. Such information is also performed by the equipment management unit 12 based on the standard equipment and materials stored in the factory equipment database 15, past materials and equipment ordered, design drawings and specifications, and the like. The equipment management unit 12 manages which equipment is used in which equipment and whether or not they are in stock. In addition, information is stored in the equipment database 17 in order to manage detailed data for each equipment. In FIG. 1, the equipment database 17 is provided independently.
It may be stored in the factory equipment database 15.

In this manner, the maintenance department 1 creates a construction plan using the plan creation device 10 and manages information on what kind of equipment is required for each construction. Information is stored in each database. The work based on the construction plan is provided to the user via the display / output unit 13, and receives an instruction from the user via the input unit 18. The central processing unit 14 collectively processes these functions, and operates using a separate memory or the like.

By the way, the conventional plan creation device also creates a plan in the same manner as in the above-described embodiment, but this embodiment further has the following features. The equipment management unit 12 according to the present embodiment refers to the plan created by the construction plan creation unit 11 and extracts data of all the equipment required for each construction.

For example, in FIG. 5, in the construction (A), the construction (A), the construction (C), and the construction (D), three, three, one, and two materials A are required respectively. I do. Therefore, it can be understood that nine materials A are required in the period shown in FIG. As described above, it is possible to reduce the purchase unit price by purchasing more at once rather than purchasing a small number of these materials and equipment.

Therefore, in this embodiment, in order to be able to purchase the same equipment at the same time as much as possible, the ordering time of each equipment is consolidated based on the data of all the extracted equipment. In FIG. 5, a total of nine materials A are required for the construction (A), the construction (A), the construction (C), and the construction (D). Among them, the construction (a), the construction (c) and the construction (d) are close in time, and the construction (a) is scheduled to be carried out at a great distance in time. Therefore, the equipment A required for the construction (a), the construction (c) and the construction (d) are ordered at once, and the equipment A required for the construction (a) starts the construction (a). Be able to order at the right time.

For this reason, in the present embodiment, when setting each work schedule in the work plan creation section 11, information on how far back and forth the schedule is to be entered for the start and end of the work is also input. deep. Then, each construction schedule is shifted by the plan changing unit 110 in accordance with the optimal order time of the equipment and materials. FIG. 6 is an example in which the shift time is explicitly shown. Looking at the construction (a),
A hatched portion 63 before the construction start schedule indicates a range in which the construction start schedule is shifted, and a hatched portion 64 behind the construction end schedule indicates a range in which the construction end schedule is shifted. Similarly, for the construction (c), the construction start schedule can be advanced, but the construction end schedule cannot be delayed. Conversely, for the construction (e), the construction start schedule cannot be advanced, but It is supposed to be possible to delay the end.

Therefore, in the construction (A), the construction start time is shifted to the rear as much as possible. On the contrary, in the construction (C) and the construction (D), the construction start time is shifted to the front. FIG. 7 is an example in which the construction schedules of construction (a), construction (c), and construction (d) are actually shifted. In FIG. 7, arrow 65
The range indicated by is the range width that is actually shifted. A white triangle 67 is the scheduled date for ordering the materials and equipment before the construction schedule is changed, and a solid triangle 66 is the scheduled date for ordering the materials and equipment after the change in the construction schedule. With regard to the construction (a), the construction schedule has been shifted to the rear side (the side to be delayed), so that the planned order date 66 after the construction schedule change is later in time than the planned order date 67 before the construction schedule change (FIG. 7). (Right side), construction (c) and construction (d), etc., the construction schedule is shifted to the front side (earlier side), and ordering of materials and equipment A is performed together with construction (a) The scheduled order date 66 is set on the same schedule as the construction (a).

As described above, by shifting the construction schedules of the construction (A), the construction (C), and the construction (D) back and forth, the time when the materials and materials A are required can be determined before the initial construction schedule is shifted. It becomes possible to consolidate in a shorter period of time as compared with the state of.

The range 68 indicated by the one-dot chain line in FIG. 7 is based on the work plan before the change of the work schedule, the work (A), the work (C), and the materials A used in the work (D) are performed in the work (A). According to the construction schedule, after ordering materials and equipment A items at once,
This shows the stock period until the construction (d) is actually started. However, in order to simplify the figure, the period from ordering to delivery is omitted, and the period from ordering to start of use is shown. Similarly, the range 69 indicated by the two-dot chain line indicates the stock period from the time when the order of the materials A after the construction schedule is shifted in this embodiment is ordered and the time when the construction (d) is actually started. It is a thing.

As described above, as a result of consolidating the order dates for the materials and equipment A by shifting the construction schedule, the construction (a),
Equipment A goods 9 required for construction (c) and construction (d) 9
It is possible to shorten the period for storing the delivered material A in the factory as inventory, compared to the case where the individual items are simply ordered. In addition, the construction (A), the construction (C) and the nine materials A required for the construction (D)
Can be ordered at the same time as the start of the process, so that a large number of orders can be made at once, thereby reducing the unit purchase price.

Furthermore, in the construction work, when the construction plan creation section 11 sets each construction schedule, the timing of which equipment and materials are required at which timing in the construction period can be entered more finely. The schedule can be shifted. In other words, in the above-described example, the construction (A) shifts the construction start time to the rear as much as possible, while the construction (D) shifts the construction start time to the front.
If only the equipment A items are used, if the time to use in each construction is known, the construction start time of the construction (a) is shifted to the later, and conversely, the construction start time of the construction (d) is earlier. In some cases.

In the above-described example, each construction schedule is shifted by focusing only on the material A, but by examining the timing of shifting the schedule together with other necessary equipment, the inventory condition in the factory is examined. Can be optimized.

In the present embodiment, when the construction schedule is set by the construction plan creation section 11, information on how far back and forth the construction schedule is to be shifted for the construction start and construction end times is input. The construction schedule can be automatically shifted to the optimal time. In addition, the timing of shifting the construction schedule is automatically set by the plan change unit 110 based on the information input in this manner, and the user can also set any time at the plan change unit 110 via the display / output unit 13. It may be shifted in the range. In this case, if the user shifts beyond the possible range, an error display or the like may be displayed.

Next, the flow of the operation of the plan creation device according to the present embodiment will be described with reference to FIG. First, a construction plan is created by the construction plan creation unit 11 based on data such as a design drawing and specifications of equipment stored in the factory equipment database 15 (step S1).

Based on the construction plan created in step S1, what kind of equipment and materials are required for each construction is extracted, and among them, it is determined whether or not there is the same equipment and materials used in a plurality of constructions. Is checked (step S2).
Here, if the same equipment is not used for a plurality of works (No), the work plan is adopted as it is, and the work ends.

On the other hand, when there is the same material used in a plurality of works (Yes), the process proceeds to step S3, and information on any one of the materials is extracted from the information on the material.
Next, a construction start schedule of the construction that is started earliest among a plurality of constructions is extracted (step S4). For example, FIG.
In the construction plan shown in (1), materials and equipment A are required for a plurality of constructions (A), construction (A), construction (C), and construction (D), and the construction (A) ) Will be extracted.

If the construction start schedule of the earliest construction extracted in step S4 can be delayed in time (Yes in step S5), the plan change unit 110 sets the construction start schedule for an appropriate period. Is delayed (step S6). Conversely, if the construction start schedule cannot be delayed (No in step S5), or if the construction schedule of the construction extracted in step S4 is delayed in step S6, the next construction schedule is extracted (step S7). ).

If there is a margin to shift the construction start schedule or the construction end schedule back and forth with respect to the construction schedule extracted in step S7 (Yes in step S8), the plan change unit 110 needs the construction schedule extracted in step S7. (Step S9). On the other hand, if there is no room to shift the construction schedule extracted in step S7 (No in step S8), the process proceeds to step S10 without shifting the construction schedule.

If there is another construction schedule that requires the same materials and equipment (Yes in step S10), the processes in steps S7 to S9 described above are repeated, and each construction schedule is shifted within a range to be shifted. Is completed (No in step S10), it is confirmed whether or not there is another common equipment in the entire construction plan (step S11). The process of S10 is repeated.

As described above, the plan creator according to the present embodiment uses the construction schedule created by the construction plan creator 11 based on the same materials and equipment required for a plurality of constructions as the construction scheduler 110 with the construction scheduler. It has the function of shifting

Conventionally, when a construction plan is set, materials and equipment cannot be arranged only based on the construction plan. However, in this embodiment, data is created so that the schedule of the construction plan is shifted back and forth. When the same equipment is required in multiple construction schedules, orders can be placed so that the construction period can be shifted to shorten the stock period in the factory, and the unit price can be reduced by arranging the equipment and materials in a batch. It is devised so that it can be done.

(Second Embodiment) Next, a second embodiment of the present invention will be described. FIG. 3 is a diagram illustrating a configuration example of a plan creation device according to the second embodiment. In FIG. 3, blocks having the same functions as the blocks shown in FIG. 1 are denoted by the same reference numerals. In the second embodiment, the purchasing department 3 is provided with an external connection unit 30 and is connected to an external computer network. External connection portion 30 is, for example, a web browser,
A website can be accessed via a computer network such as the Internet.

In FIG. 3, the marketplace 5 is:
An electronically built market where various sellers, including equipment manufacturers, open virtual stores, and customers who wish to purchase electronically order equipment, etc. from multiple virtual stores. It is a system to purchase. Purchasing department 3
Can access the marketplace 5 via the external connection unit 30 and order materials and equipment. In Marketplace 5, purchasers can compare price differences and delivery times for each product sold at each virtual store, so they can place orders at stores that meet their purchase conditions. It becomes possible.

Therefore, in the present embodiment, the purchasing department 3 accesses the marketplace 5 based on the construction plan created by the maintenance department 1 and inquires about the product unit price / delivery date and the like, and based on the returned information. Stagger each construction schedule.

FIG. 8 is a flowchart showing the flow of the operation in the second embodiment. First, in the maintenance section 1, similarly to the above-described first embodiment, the construction plan creation unit 10 creates a construction plan (step S20). Then, the necessary quantity of equipment and the required time are extracted, and the data (material and equipment data) is transmitted to the purchasing department 3 (step S21).

The purchasing department 3 which has received the equipment data transmitted from the maintenance department 1 inquires each of the equipment manufacturers 1 to m of the marketplace 5 about the sales unit price and the delivery date using the equipment data (step S22). .

The purchasing department 3 having received the responses from the respective equipment manufacturers 1 to m transmits the data to the plan changing unit 110 of the maintenance department 1 as the conditions for estimating the equipment (step S).
23). At this time, the purchasing department 3 may delete unnecessary replies and then transmit them to the plan changing unit 110. For example, items whose delivery date is likely to be significantly delayed or whose unit price is too high may be deleted.

In this way, when the estimation condition of the equipment is input to the plan changing unit 110, the plan changing unit 110
An optimum construction schedule is determined based on the estimated conditions of these materials and equipment, and each construction schedule is shifted back and forth (step S24). Step S24 is substantially the same as step S2 to step S11 in the flowchart of FIG. 2 described above, and a description thereof will be omitted.

As described above, in the second embodiment, the delivery date and purchase unit price are actually inquired to the equipment manufacturers 1 to m, and the answers are used to shift the construction schedule. It is a plan creation device that can create a construction plan. In addition, similarly to the first embodiment,
In addition to automatically changing the plan in the plan changing unit 110, the user may shift the plan in an arbitrary range by the plan changing unit 110 via the display / output unit 13.

The external connection unit 30 of the purchasing department 3 and the marketplace 5 itself use a web browser or the like which has been conventionally used, and are obtained from the marketplace 5 through the external connection unit 30. It is sufficient that the information can be used as data for shifting the construction schedule using the information, and the form is not particularly limited.

(Third Embodiment) Next, a third embodiment will be described. FIG. 4 is a diagram illustrating a configuration example of a system to which the plan creation device according to the third embodiment is applied.
In FIG. 4, blocks having the same functions as the blocks shown in FIGS. 1 and 3 are denoted by the same reference numerals. In the first embodiment and the second embodiment described above, the maintenance department 1 includes the plan creating device 10 for creating only the construction plan of the factory 2, but in the present embodiment, the plan creating device 10 , A plurality of factories 1 to n (21, 2
It has a function for creating a construction plan of (2, 23).

As described above, in order to manage the construction plans relating to the plurality of factories 21 to 23, the factory equipment database 15 and the construction plan database 1 provided in the plan making device 10 are provided.
6 and the materials and equipment database 17
Data is stored for each of 2, 23, and a construction plan can be created for each.

The factories 21 to 23 may be physically separated or not. For example, a single company may have a plurality of factories located geographically apart from each other, or may be factories belonging to different companies. FIG. 4 shows an example in which construction plans of a plurality of factories in one company are managed. Therefore, only one purchasing department 3 is shown. For example, the maintenance department 1 performs maintenance management (maintenance service) of different customer companies. The purchasing department 3 is also provided with a purchasing department 3 for each customer company, and may perform order processing based on a construction plan, or the maintenance department 1 may have a purchasing function. You may do it.

In the present embodiment, the maintenance section 1 first creates a work plan for each factory by the plan making device 10 and stores it in the work plan database 16. At this point, the construction schedule may be shifted for each factory using the plan changing unit 110. This work is performed for the factories 21 to 23, and the respective construction plans are stored.

Next, all the equipment and materials required for the construction plan at a plurality of factories are extracted, and if there are the same materials and equipment as those of the other factories, they are aggregated. Refer to each construction schedule. Then, similarly to the first and second embodiments described above, if there is a construction schedule that shifts the construction start schedule or the construction end schedule, the construction schedule is updated by the plan changing unit 110 to update the construction schedule database 16. I do.

If the maintenance department 1 is a company that performs maintenance management (maintenance service) for different customer companies, for example, the construction schedule is shifted based on only the equipment information within the same company or the company is changed. It is preferable to set in advance for each construction plan whether the construction schedule is to be shifted based on the equipment information.

As described above, the maintenance department or the maintenance service is performed by consolidating materials and equipment and changing the construction plan based on the construction plan of not only one factory but also a plurality of factories over a wider area. Companies will be able to reduce the time required to keep materials and equipment needed for construction in stock until they are actually used in construction at each factory. In particular, a higher effect can be obtained when many plants need to be maintained and managed.

On the other hand, for example, in one factory or one company, the factory side is used only for one construction, and even in the case of materials and equipment for which the purchase price cannot be reduced because of a small lot. If the same materials and equipment are to be used in other factories or companies, shifting the construction schedule has the effect of reducing the purchase price in the factories.

In this embodiment, an example has been described in which one maintenance department 1 creates and changes a construction plan for a plurality of factories as shown in FIG.
Companies often have multiple factories in geographically separated locations. In this case, conventionally, the maintenance department 1 is assigned to each factory.
Was set up, a construction plan was created for each factory, and each construction was performed. On the other hand, in the present embodiment, since the construction plan of each factory can be managed comprehensively, the following processing can be performed.

If each factory has a maintenance department, the construction plan created there is transmitted to the general maintenance department. If there is no maintenance department in the factory, the general maintenance department creates a construction plan for the factory. Next, the general maintenance department stores the construction plan transmitted from each factory and the construction plan created by itself in the construction plan database 16, and uses the stored construction plan to schedule the construction schedule in the plan change unit 110. Make changes such as shifting.
As described above, in the present embodiment, the construction plan of each factory can be comprehensively managed whether or not the factory has a maintenance department, and even if the factories to be constructed are geographically separated, This makes it possible to shorten the stock period of materials and equipment and the purchase unit price.

The embodiment described above is only an example, and the present invention can be modified in various other modes. For example, by combining the second embodiment and the third embodiment described above, the maintenance department prepares / changes a construction plan of a plurality of factories or factories of a plurality of companies, and the unit price of the material and equipment in the marketplace 5.・ Delivery time is 1 to m
The construction plan may be changed after contacting.

Each of the embodiments described above is constituted by a computer CPU or MPU, RAM, ROM, etc., and can be realized by operating a program recorded in the RAM or ROM. Therefore, the present invention can be realized by recording a program that causes a computer to perform the above function on a recording medium and causing the computer to read the program. As a recording medium,
A CD-ROM, floppy (registered trademark) disk, hard disk, DVD, magnetic recording medium, optical recording medium, semiconductor memory, or the like can be used.

The functions of the above-described embodiments are realized when the computer executes the supplied program, and the OS (operating system) or other application software running on the computer. It goes without saying that such a program is also included in the embodiment of the present invention when the functions of the above-described embodiment are realized in cooperation with the above.

[0072] In addition, a program product such as a computer which the program is embedded are included in embodiments of the present invention.

[0073]

As described above, according to the present invention, since the data is created so that the construction schedule of the construction plan is shifted back and forth, the same equipment and materials are required in a plurality of construction schedules. In addition, a construction plan should be created so that the construction schedule can be shifted so that the inventory period of materials and equipment in the factory can be shortened, and the unit price of materials and equipment can be reduced by ordering the equipment and materials at once. Can be.

Further, when the delivery date and purchase unit price of the equipment and materials are actually inquired to the marketplace and the answer is used to shift the construction schedule, a more accurate construction plan can be created.

Further, based on a broader construction plan of a plurality of factories, etc., by consolidating the materials and equipment required for the construction and changing the construction plan, the maintenance department or the company providing the maintenance service can perform the construction. The time required to keep the equipment and materials needed for inventory at each factory until it is actually used can be shortened, and the factory can use it only once for a small lot. Even if the equipment and materials cannot be purchased at a low price because of the same reason, if the same equipment and materials are to be used in other factories or other companies, the construction schedule will be shifted to the equipment and materials in the factory. The purchase price can be reduced.
