Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for monitoring design work and guiding work, and particularly suitable for performing work guidance when a plurality of designers or sections perform simultaneous distributed processing. The present invention relates to an engineering work monitoring work guidance support device.

[0002]

2. Description of the Related Art In designing a product, the designers of a plurality of sections usually share the design work. Hereinafter, a method of designing by sharing a plurality of designers will be described, taking a case of designing a plant or the like using a computer support device (CAD device) as an example.

The design of a plant is roughly classified into an upstream design that determines design conditions and a downstream design that receives the design and designs in accordance with the design conditions.

[0004] In the series of work from the upstream design to the downstream design, each division and procedure are predetermined, and for example, in the case of piping, piping route planning → stress analysis of piping → piping The procedure is called construction design. When changes are made to these designs, coordination is carried out among the persons in charge, the layout plan is reviewed, the changes made in the upstream design are reflected in the downstream design, and the changes made in the downstream design are made upstream. Feedback to the side design is implemented.

At this time, the influence on the master schedule between the design departments due to the occurrence of the change may not be completely reflected in the master process chart (time schedule), and the original process may remain as it is.

Further, the amount of material (design data amount, number) generated by each design of a plurality of sections is enormous.
Therefore, from the viewpoint of rationalization such as reduction of physical quantity, each design source outputs a physical quantity list for each actual physical quantity on a regular basis while grasping the amount of generated physical material while proceeding with the design work.

[0007]

The design of a plant is characterized in that a plurality of designers in various fields repeatedly make changes while adjusting each other and gradually improve the design accuracy. In such a design environment, the following events often occur.

1. Even if the layout of a certain product (for example, piping) is changed, it may affect the cohesion of the entire layout, so other related products (for example, air conditioning ducts, cable trays, etc.) may have to be changed accordingly. is there.

2. When the layout shape is changed, there is a backtrack in the downstream design such as the piping stress analysis which has already been undertaken for the design on the condition of the layout shape.

As a result, each designer has to change
It takes a lot of time to manage the correspondence by communicating the contents in writing to the related departments. Especially in piping, there are many related departments and documents, and it is difficult to grasp the range of influence widely, which may result in delays or delays in the presentation of changes, which increases the backtracking of downstream design. There is.

3. Basically, it is desirable that each designer can automatically recognize the change (increase / decrease) in the physical quantity due to the design change on the upstream side, and each designer can confirm the physical quantity change content for the change factor on the terminal (on the screen).

Further, it is desirable to be able to timely grasp the forecast calculation management of the target physical quantity initially set (planned time) and the physical quantity currently occurring. Furthermore, it is desirable to be able to predict and grasp the amount of material that will be generated in the future.

4. It is desirable to be able to more accurately and smoothly reflect the changes (schedule adjustment, changes, etc.) that accompany changes in the design and installation process (master schedule) that accompany changes in the design.

In Japanese Patent Laid-Open No. 4-367049, a system consisting of a plurality of information processing devices connected by a communication line is used to change the design of each information processing device by one information processing device (management source). The management technology is disclosed. In the information processing device that has received the change notification from the management source, the user determines whether or not the change has occurred. However, this conventional technique has a problem in that the burden on the user is heavy because the user has to determine whether or not the received change notification is affected. Also,
There is also a problem that even a change notification, which is not always necessary, is transferred on the communication line.

Although the design process is not distributed processing,
The following are known techniques that are partially related to the present invention.

In Japanese Patent Laid-Open No. 62-14266, a change element is extracted based on the difference in the color information of the construction design drawings before and after the change, and a construction budget estimate is automatically output from the attribute information of the deletion element and the extension element. Techniques for doing so are disclosed.

Japanese Unexamined Patent Publication No. 62-267874 discloses another layout object which is laid out in a design support device for laying out piping or the like by mutually (physically) affecting a specified layout object. It discloses technology for seeking things. Also, U.S. Pat. No. 4,885,69
Japanese Patent Publication No. 4 discloses a technique for automatically generating a changed drawing, estimating and designing a system design cost, and the like regarding the design of a building control system. However, none of them discloses measures against the influence of the design change between the upstream side and the downstream side of the distributed design.

An object of the present invention is to provide a distributed design environment,
It is an object of the present invention to provide a design work support method and apparatus for solving the above problems, managing design data, and facilitating work from upstream to downstream of design.

[0019]

In order to achieve the above object, in the design work management support apparatus according to the present invention, a plurality of designers share each part of the entire design process from upstream to downstream by a plurality of design support apparatuses. A device that manages and supports design work when performing parallel distributed processing, and stores the design target and other design targets affected by the change in advance as design change impact management data. Every time, when there is a design change in a certain design support device, the design support device that detects the design object having an influence by referring to the design change impact management data and shares the design of the detected design object , The contents of the design change are automatically notified. This notification is performed, for example, via a shared memory that can be accessed by the plurality of design support devices.

Further, in at least one design support device of the plurality of design support devices, in accordance with the design change,
At least one of physical quantity management data of each design object, estimation data, design progress management data, and design delay follow-up data can be displayed on the display device.

[0021]

In the device of the present invention, the
Since the design change influence relationship management data, which defines the correspondence relationship with the design target affected by the design change of the design target, is stored in advance, when the design target is changed, the change is made to any other design. Immediate recognition of the impact on the subject. The contents of this influence are notified to the design support device related to the design target that is affected via the shared memory. Therefore, since a plurality of designers can mutually confirm the contents of the change, the degree of the influence, and the work contents generated thereby, the wasteful work can be minimized.

Further, by referring to the master process data (master schedule file) with respect to the current design progress state, it is possible to recognize and manage the actual result of the scheduled schedule, that is, the progress situation. By doing so, the design delay of each design target is grasped,
For example, the work can be promoted by generating a design promotion alarm for the design target.

As described above, the consistency of the data between the design works can be maintained, the work can be smoothly guided, the design failure can be prevented, and the design efficiency and the design reliability can be improved. it can.

Furthermore, the actual amount of physical quantity generated when compared with the planned physical quantity data for each physical quantity generated by each design source and design target is displayed, and the future physical quantity generation forecast (transition) in which the design overwork work volume is recognized is displayed. ) Values can be provided to each designer one after another.

Next, based on FIG. 3, the first design support device 1
The processing contents when the piping layout data is corrected will be described in. The designer is the layout design program 8
Start, and enter the name of the piping route or the work range to be corrected from the keyboard 6 or mouse 7.
Specify using. The designated target data is retrieved from the memory 24A storing the layout design data,
It is stored in the working memory 4 via the CPU 2 and displayed on the display 5. The work memory 4 temporarily stores programs and data used during a predetermined design work, and data obtained by the design. The designer interactively modifies the layout data while looking at the data displayed on the display 5 (step 41). The corrected data is stored in the working memory 4 (step 4
2). The correction is once completed, and at the same time, the influence content detection / display / registration interface program 9 for confirming the influence on other designers is automatically started, and the design change influence relation management data in the memory 24B is referred to ( Step 4
3). If the corresponding data is not found in the memory 24B, it is determined that the modification of the layout data does not affect other design objects, and the fact that there is no problem is displayed on the display (steps 44 and 48). When the corresponding data is found, the corresponding program name in the memory 24B is returned to the influence content detection / display / registration interface program 9, and the corresponding influence content detection / display / registration program 10 is activated. (Steps 44 and 45). The influence content detection / display / registration program 10 detects the influence using the layout design data of the memory 24A and the corrected piping layout data of the working memory 4, and displays the result on the display 5 (steps 46 and 47). . If not detected, it is displayed on the display 5 that there is no influence on others (steps 46 and 48).

Depending on the contents, for example, for the pipe stress analysis model, the model name and the result of the consistency judgment (in this example,
(The model shape and the piping route shape no longer match), because the design has already been undertaken, it is necessary to contact the designer in charge as soon as possible. It is recognized whether or not this should happen. As will be described later, when this change is determined, information about the change is written in the memory 24C, which is a shared memory, so that the design support device of the contact can recognize the change.

Next, with reference to FIG. 4, a process after the above influence result is displayed on the display 5 will be described. The piping layout designer confirms the influence result of the automatic output processing on the display 5 (step 49). if,
If it is judged that the modification should be canceled or the modification contents should be reviewed because it has a great influence on other design objects, the processing is terminated or the data is modified again. Then, the process returns to step 41 of FIG. 3 (steps 50 and 51). On the other hand, if there is no influence on the other design object, or if it is determined that the influence is unavoidable, the correction content and the reason for the correction are input as a comment from the keyboard 6 (step 52). At this time, the corrected piping layout data is stored in the memory 24A from the work memory 4 as the determination data (step 53). Then, the correction content, the reason for the correction, the influence result, etc. are stored in the memory 24C (step 54). At this time, the data contents of the plants in the design progress of the memories 25, 26, 27, 28 are updated.

Next, with reference to FIG. 6, the processing on the side affected by the above design change using the second design support device 12 will be described. The designer confirms, before the analysis work is started, whether the influence of other design changes has occurred on the pipe stress analysis model or the arbitrary pipe stress analysis model which he is currently working on. The instruction for this is automatically output by the device when the work is started (step 61). It should be noted that the confirmation instruction may be periodically output even after the launch. In response to this instruction,
Memory 24C in which design change impact data is stored for the pipe stress analysis model instructed by the influence content detection / display / registration interface program 20 being activated.
Is difficult to refer to (step 62). If there is no corresponding data, display 1 that there is no corresponding data.
6 is displayed (steps 63 and 64). If there is corresponding data, its contents are retrieved from the memory 24C,
It is passed to the influence content detection / display / registration program 21 (steps 63 and 65), and the content is displayed on the display 16 by the influence content detection / display / registration program 21 (step 66).

FIG. 7 shows an example of the display result of the above contents.
Here, the piping route correction is added to the piping stress analysis model of the worker in the second design support device in the preceding piping layout design, and the piping stress analysis model data of the plant currently under construction is added. It is confirmed that there is a mismatch. In addition, as the reason for the revision, it was confirmed that the revision was unavoidably implemented based on the design specification change, or that the piping layout was not finalized and is still in the review stage,
It is judged that continuing the current design is not a good idea because it causes a backtracking work.

The embodiment described above is not limited to the layout design, but is also an apparatus (for example, a machine tool) provided with a plurality of parts.
It is also applicable to the design of.

Next, referring to FIG. 12, various display processes using the second design support device 12 due to design changes will be described.

When the designer finds that the work he is currently working on is affected by the change in the design of another department, the designer designates various display types by the processing of FIG. 6 described above. (Step 610). For example, when displaying the physical quantity, the physical quantity calculation / display program 10 is instructed by the instruction (step 612).

When only 6 exists, they may be displayed on the display 16.

Here, a display example of the data relating to the physical quantity stored in the memory 25 of FIG. 1 will be described with reference to FIG. In the memories 25A and 25B, the design target items, the physical quantities of the plan data and the construction data, respectively, are stored as the existing plant physical quantities and the design-in-progress plant physical quantities for each of the target items. Further, the target physical quantity, which is the final physical quantity of the design-in-progress plant, which is predetermined with reference to the existing plant physical quantity, and the future physical quantity are calculated and stored. The planned data quantity is represented by the weight of the material itself before being machined, and the construction data quantity is represented by the weight after processed. The future physical quantity is the volume of future increase in the planned data. The contents displayed on the display 161 are these physical quantity data regarding the design items to be design changed, and the designer can confirm the change (increase / decrease) in the physical quantity data due to the influence of the design change and confirm the physical quantity occurrence status. You can check again. At the same time, it is possible to confirm the amount of material that is expected to be generated in the future, so it is possible to grasp the whole picture of the amount of material generated for each design item. Forecasted physical quantity is as described below.
Calculated.

With reference to FIG. 14, an outline flow of the calculation processing of the future expected physical quantity will be described. First, by designating the existing plant name, building name, system name, and line number of the target line, the target quantity Q1 of the design-in-progress plant is calculated based on the existing plant quantity of the target line (A1). . Next, the present generation amount Q2, which is the planned data amount of the plant under design, is searched (A2). The expected generation amount is calculated by subtracting the current generation amount Q2 from the target amount Q1 (A3).

FIG. 15 shows a detailed flow of the target quantity calculation shown in step A1 of FIG. First, the operator specifies (inputs) the corresponding (or required) existing plant name (A11). At this time, as the information retrieval unit of the existing plant, it is possible to specify all system units, building units, or line units. Then the building,
A system and a line name are designated (A12). In response to this, the existing plant quantity file (stored in the memory 25) is searched (A13), and the target quantity of the target line is calculated based on the retrieved data (A14).

The target quantity of the plant under design is
Based on the actual data of the physical quantity of the existing plant of the same kind, various parameters can be taken into consideration for this. For example, in a power generation plant, a power generation output ratio f1, a system configuration (system classification) f2, a pipe diameter ratio f3, a heat insulation classification (heat insulation classification according to the pipe internal temperature) f4, an earthquake resistance classification (As, A) , B ...)
It is obtained by multiplying the physical quantity data of the existing plant by the product F of f5, pipe type classification (first type, third type, ...) F6, material type f7, and the like. Here, the parameters f1 to f7 are numerical values larger than 0 (for example, real numerical values around 1).

Returning to FIG. 12, the processing process relating to the estimation (cost) by the design change using the second design support device 12 will be described.

The designer inputs a quotation display instruction for an existing plant and a plant in progress of design when the work he is currently working is affected by a design change (step 615). The data calculation / display program 102 is activated to refer to the memories 26A and 26B in which the designated estimation data is stored (step 616). The content is displayed on the display 161 by the estimation data calculation / display program 102 (step 617).

Referring to FIG. 9, a display example regarding the estimated data of the design object stored in the memory 26 of FIG. 1 will be described. In the memories 26A and 26B, design target items, cost (estimation) data of an existing plant (for reference) for each of the target items, and actual data of a plant under design are stored. The unit of the numerical value is, for example, 1,000 yen / kg
Is. The estimation data of the plant under design can be obtained by referring to the estimation data of the existing plant according to the specification difference such as the scale (output) of the plant as in the case of the physical quantity. The actual data of the plant under design is updated as the design progresses. The contents displayed on the display 161 are these illustrated data regarding the design items to be design-changed, and the designer can confirm the change (increase / decrease) in the estimation data due to the influence of the design change.

Returning to FIG. 12, the display processing of the progress status due to the design change using the second design support device 12 will be described.

When the designer recognizes that the work he is currently working is affected by the change in the design of the other department, he / she can give an instruction to display the progress status (step 618). . In response to the instruction, the master process data of the plant under design, the design delay data calculation / display program 103 are activated, and the designated master process data and the design delay data are stored in the memories 27A and 27B. Go to step (step 61)
9). The contents are displayed on the display 16 by the master process data and design delay data calculation / display program 103.
