Technical Field

Background

The airplane equipment system is a large complex system, and demand engineering becomes an indispensable important link for system development. In the model development process, activities such as requirement capture, requirement analysis, function analysis, architecture design, requirement definition, confirmation and verification are developed according to the requirement engineering requirements, and a requirement library is built for overall process data management. A Product Breakdown Structure (PBS) defined based on the design of the aircraft architecture represents a hierarchy of the aircraft from top to bottom from systems to hard, software. Through the logic sequence and interaction of system functions or elements, the final evolution becomes a final optimized architecture scheme. The directory structure and hierarchical relationship of the requirement library reflect the logic correlation and consistency of each system and element composition, and a method for automatically generating the directory and entry codes of the requirement library based on architecture design needs to be researched.

Files in the conventional requirement library are stored in a scattered manner according to a professional folder mode, and the element relationship between the system and the hierarchical relationship of requirements cannot be expressed.

Meanwhile, codes of PBS nodes cannot be automatically obtained without establishing association, sequence number errors are easily caused when codes of each requirement are manually compiled, and meanwhile, coding normativity and identifiability are poor when English letters are coded in short form and pinyin initials are coded in some cases.

Detailed Description

The method comprises the steps of establishing and reading a product decomposition structure, establishing association between a demand directory of a demand information management platform and the product decomposition structure of a product data management platform, and establishing a multi-level demand directory according to a level structure of 'airplane demand-system demand-subsystem demand-product demand'. And meanwhile, the name and the code of the product decomposition structure node are read, and the automatic generation and configuration of the demand directory name and the entry code are realized. The method for constructing the demand directory structure based on the architecture design is initiated domestically.

The process of creating and encoding the demand catalog is as follows:

the method comprises the steps of firstly, developing an airplane architecture design on a product data management platform, building a product decomposition structure, carrying out system decomposition, identifying and refining system composition and defining each level node, wherein the product decomposition structure (PBS) is built layer by an airplane-system-subsystem-device and software, and a structure model is shown in figure 1.

And step two, after a product decomposition structure in the product data management platform establishes a file node FI at the current level (as shown in figure 2), the demand information management platform correspondingly constructs a demand directory structure (as shown in figure 3), and a demand file is placed under the directory.

Step three, the requirement information management platform reads the hierarchical structure feature and the node name of the file node in the product data management platform, and names the requirement directory and the requirement file under the directory, as shown in fig. 4.

Setting codes when the product data management platform establishes the PBS file nodes, wherein the codes comprise code bits (shown in figure 5) which embody a hierarchical structure, the lengths of the code bits are fixed, and the lengths of the code bits are consistent by zero padding of the hierarchy which the nodes do not reach;

and fifthly, after the demand directory is generated, reading codes of PBS file nodes in the product data management platform by the demand information management platform, intercepting the hierarchical structure and effective code bits in the codes according to the rules of the table 1, and generating the codes which need to be configured in the content of the demand items in the demand file.

TABLE 1 requirement entry encoding rules

Serial number	Demand hierarchy	Requirement item encoding rules	Base line
				1	Equipment level requirements	X plane system code-RQ-1	Functional baseline
2	System level requirements	X system code (3 bit) -RQ-1	Dispensing baselines
				3	Subsystem level requirements	X subsystem code (5 bit) -RQ-1	Dispensing baselines
4	Product hard/software development requirements	X device code (7 bit) -RQ/SQ-1	Dispensing baselines

And step six, automatically configuring the intercepted requirement item codes into a requirement information management platform.

And seventhly, setting an attribute identifier of each item information in the requirement information management platform, checking whether an item code is generated in the attribute identifier, and sequentially coding the items required by the attributes according to a coding rule and generating the items into the text content of the requirement file.

And step eight, when the nodes of the product decomposition structure in the product data management platform are deleted, sending a confirmation notice to the demand information management platform, and deleting and modifying the demand catalogue after confirmation.

The invention relates the generation of the demand directory and the configuration of the item code with the product decomposition structure, and automatically and synchronously updates the demand directory structure according to the latest result of the architecture design. And carrying out the interception of each level of requirement codes according to the codes of the nodes of the product decomposition structure, automatically configuring the codes to a platform and generating the codes into the text content of the requirement file, thereby ensuring a coding system unified with the product decomposition structure and meeting the coding normative requirement. The invention realizes the construction of a hierarchical structure of the demand directory, realizes the linkage of the demand and the design, expresses the system architecture by the demand library directory, realizes the automatic configuration generation by the information interaction between platforms, is pioneering in the industry and has a technology leading position.
