Problems solved by technology

[0004] Currently, the management of the whole product life cycle adopts a static model management mode, mainly relying on the independent management of the independent system platform at each stage of the life cycle. Smooth, cumbersome interoperability, and complex relationships that are difficult to coordinate. It is difficult to quickly improve product design efficiency and quality. There is still a lack of basic theory and platform guarantees in the early stage of product system design. The following problems exist:
There is also a lack of an efficient model-based cross-unit, cross-stage, and cross-level coordination mechanism

Embodiment approach

[0047] Embodiments of the invention and features of the embodiments may be combined with each other without conflict.

[0048] The method for constructing a full life cycle model of a product in the technical solution of the present disclosure is suitable for constructing a model of a complex product, wherein the complex product uses high technology, adopts complex technology, has a large number of parts, has many product structure levels, and changes between parts and products. Products with many relationships and high value at the same time, such as the modeling of products such as aircraft and vehicles.

[0049] In the development process of complex products in the whole life cycle, the unified quantitative description and modeling theory and technology need to be improved at each stage, the comprehensive integration of the system is not high, and it is difficult to collaborate across disciplines, fields and stages. Therefore, it is necessary to solve the whole life cycle of...

Embodiment 1

[0052] This embodiment discloses a method for constructing a full life cycle model of a product, including:

[0053] Building MDA: The architecture consists of four model levels, such as figure 1 As shown, the instance layer (M0) is composed of specific data of a specific object, and the instance is the instantiation of the model. Model layer (M1) is a template abstracted for describing specific business. Metamodel layer (M2) is an "abstract language" defined to describe the model layer, which is a further abstraction of the model layer; the model is the inheritance of the metamodel. Meta-Meta-model layer (M3) is an "abstract language" defined to describe the meta-model; the meta-model is the inheritance of the meta-meta-model. Here is an example of a four-layer model, such as figure 2 shown.

[0054] Definition model: Definition of model types and systems for different needs; provide all model definitions required for digital design modeling for the full life cycle of pr...

Embodiment 2

[0079] The purpose of this embodiment is to provide a computer device including a memory, a processor, and a computer program stored in the memory and executable on the processor, the processor implementing the steps of the above method when executing the program.

Abstract

The invention provides a product full life cycle model construction method and system. The method comprises the following steps: obtaining a meta-meta model from a database; creating a meta-model oriented to the demand model based on the meta-meta-model combination; creating a product structured demand model based on the meta-model combination; searching related instances in a design demand instance library for the product structured demand model based on the meta-model, the attributes of the meta-meta-model and the relation characteristics; judging whether the instance is matched with the demand model or not through domain matching degree calculation, and if yes, incorporating the instance into a demand instance set to be pushed; outputting a demand instance set and a demand list; and if not, constructing a new product design demand instance until the new product design demand instance is matched with the demand model. According to the method, an efficient cross-unit, cross-stage and cross-level cooperation mechanism is met, system-level multi-scale definition of complex products is supported, visualization and traceability of the whole design process are achieved, and the product quality is improved.

Description

technical field [0001] The invention belongs to the technical field of digital design, and in particular relates to a method and system for constructing a full life cycle model of a product. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] At present, the management mode of static model and the independent management mode and method of each stage are generally adopted in each stage of the whole life cycle of complex products. [0004] At present, the static model management mode is currently used in the management of the whole life cycle of the product, which mainly relies on the independent management of the independent system platforms at each stage of the life cycle. Due to the complex relationship of smooth, cumbersome interoperability, and difficult collaboration, it is difficult to rapidly improve product design efficiency and qualit...
