Abstract

The present invention relates to a system modeling technology and, more specifically, relates to a method and system for organically connecting model-based systems engineering (MBSE) and process integration and design optimization (PIDO), thereby clearly and intuitively expressing necessary common parts between professionals involved in a project and being able to increase a connection performance between an object to be designed and a design process.

Description

[0001] The present invention relates to a method of linking a sub-system model with an integrated design using an intermediate object, and a linking system of the sub-system model and a design system,

[0001] The present invention relates to a system modeling technology, and more particularly, to a system modeling technology, in which model-based system engineering (MBSE) and PIDO (process integration and design optimization) How to express common parts clearly and intuitively, to increase the linkage between the design object and the design process, and its linkage system.

Two features of the submarine design are that the submarine is a very complex complex system and that it is a complex process carried out by a large number of expert groups with a wide range of knowledge.

System Engineering (SE) is currently being actively applied to systematically develop a submarine as a complex system. The system engineering method that is currently applied practically is centered on the document system, so it can be called 'document based system engineering'. When systems are developed according to document based system engineering procedures, it is possible to faithfully manage the evolving requirements and / or design development process accordingly. However, it does not clearly relate the close relationship between the design act and the object to which it is applied.

This can be an obstacle in the development of systems where expertise is closely linked and exchange and understanding among interested stakeholders is particularly important. Attempts have been made to apply Model Based Systems Engineering (MBSE) to the development of submarines as the need to clearly and intuitively represent submarines as design targets has increased.

Specifically, the system modeling language, SysML, is used to construct a submarine system model and to put it at the center of system engineering design development process. The system model is the sum of the factors that reflect the four main viewpoints of system requirements, system components and relationships, system behavior, and how to meet the requirements, and the contents of the model can be created and inquired through various diagrams.

Due to the characteristics that various experts in the field should participate in, application of process integration technology and related tools called PIDO (Process Integration and Design Optimization) is attempted. PIDO technology can be used independently in various fields such as multidisciplinary design process, eg shape design, structural strength calculation and design using finite element method, linear design using computational fluid dynamics, integration effect estimation, cost and development risk estimation It is a technology that enables the integration process to be executed by interworking with a single integrated execution framework without modifying the tools.

Currently, MBSE and PIDO are technologies that operate independently of each other. The concept of this is shown in Fig. Referring to FIG. 1, the MBSE framework 110 and the PIDO framework 120 are not interrelated. That is, MBSE and PIDO are performed alone without current interconnection. Therefore, there is a problem that data consistency between the design object and the design action is undermined.

In addition, MBSEs that use SysML can represent attributes of design objects and include attributes and simple parametric relations between them, but there are limitations in modeling detailed design behavior. Even if it can express detailed design behavior, it makes the system engineering activity which is the original purpose of MBSE excessively complicated. In other words, the MBSE can not express the content of the design action in detail.

Also, in the case of PIDO, there is no explicit or concrete expression of the design subject covered by the design process in the absence of the system model. Therefore, only the input / output data is handled and the design target remains ambiguous.

The two technologies can be used in parallel, but the linking work becomes a manual action and duplicate information must be created for each. Throughout the design phase, the linkage between them is inevitable, and the inconsistency between the information used by each other leads to the possibility of errors.

The MBSE framework 210 includes a system modeling unit 211, A system model database 212, and the like. That is, the MBSE framework 210 performs a detailed designing operation to generate a system model. To this end, the system modeling unit 211 applies system engineering and performs system modeling. In addition, it is a total of elements that reflects four main viewpoints such as system requirements, system components and relationships, system behavior, and meeting the requirements according to the system modeling. .

The PIDO framework 220 refers to the system model to be designed through the intermediary intermediate object.

When the attributes of the system model are changed during the execution of the PIDO, the intermediate mediation object is immediately modified and is reflected in the system model database 212 of the MBSE framework 210 again. Modifications to the system model and / or attributes in the MBSE framework 210 immediately reflect the modifications to the intermediate mediation object and the PIDO framework 220 references the modified mediation object.

In addition, when a change occurs in the system model database 212, the intermediate object of the intermediate object unit 230 is synchronized in real time. Intermediate intermediate objects can be shared through computer memory or simultaneously in the form of files.

Referring to FIG. 7, contents to be reflected in a typical PIDO framework for instant connection between the MBSE framework 210 and the PIDO framework 220 will be described.

The PIDO framework 220 accesses the intermediate mediating object exposed by the MBSE framework 210 through the conventional general input / output device 730 and performs input / output. Changes occurring in the same information as those of the intermediate object during the execution of the PIDO are reflected in the intermediate object in real time. These operations are performed through a model search device (software device) having the same structure as that of the model searcher module 610 provided by the MBSE framework 210.
