Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a design change management support device, and more particularly, to a design change management support device for assisting a design change when a plurality of designers jointly design.

[0002]

2. Description of the Related Art Generally, a plurality of designers share the design work in designing a product. 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. In the series of work from the upstream design to the downstream design, the division and procedure of each is pre-determined. For example, in the case of piping, the route planning of piping ⇒
Piping stress analysis ⇒ Piping construction design procedure. 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.

[0003]

The design of a plant is characterized in that a plurality of designers in various fields repeatedly make changes while adjusting each other to gradually improve the design accuracy. In such a design environment, the following events often occur. 1. Even if the layout of one product (for example, piping) is changed, it affects the cohesion of the entire layout.
Other related products (eg, air conditioning ducts, cable trays, etc.) may also need to be modified accordingly. 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 communicates the contents in writing to the relevant departments each time a change is made, and it takes a lot of time to manage the correspondence. Especially in piping, there are many related departments and documents, so it may not be possible to grasp the extent of the impact, or there may be delays or delays in the presentation of changes, which increases the backward design of the downstream side. There is. An object of the present invention is to solve these problems and to provide a design change management support apparatus suitable for supporting the facilitation of design management accompanying design changes and the reduction of design time.

[0004]

The above-mentioned object comprises a plurality of design support devices and a communication line connecting these design support devices to each other. When a design change is made to a design object, the design change is made. Means for inputting related information associated with the above, a means for retrieving the information from a plurality of design support devices via a communication line, and a design support device for both the design change side and the design change affected side. By providing means for confirming the relevant information with each other,
To be achieved.

[0005]

When a plurality of designers make a design change on a certain design support apparatus in an environment in which a plurality of design support apparatuses jointly perform design work, the reason why the designer who makes the change is , Enter information about the changed contents, such as where and how, and your contact information. This information is referred to by other designers who are designing using other design support devices, and it is judged whether the design change affects their design contents. , Take measures such as immediately stopping the design or modifying the contents according to the changed contents. In addition, the designers are informed that they have confirmed each other's information and communicate with each other in a reliable manner. For this reason, when multiple designers jointly design, it is possible to easily perform design management associated with design changes, reduce the time required for design, and improve the quality of the entire design.
