    Abstract:

    This document provides Version 2.1.04 Computer Software configuration item documents for the Advanced Propagation Model (APM). The APM calculates range-dependent electromagnetic system propagation loss and propagation factor within a heterogeneous atmospheric medium over variable terrain, where the radio-frequency index of refraction is allowed to vary vertically and horizontally. The first document specifies the functional requirements that are to be met by the APM CSCI. A discussion of the input software requirements is presented together with a general description of the internal structure of the APM CSCI as it relates to the CSCI’s capability. The second document describes the design of the APM CSCI. An overview of the input software requirements is presented together with an overview of the CSCI design architecture and a detailed design description of each CSCI component. The third document specifies the test cases and test procedures necessary to perform APM CSCI qualification testing. A discussion of precise input values of each input variable required to perform the test together with final expected test results is presented

  • Method and system for design maturity evaluation and control of complex product variable configuration item
    Proceeding 2009 IEEE 10th International Conference on Computer-Aided Industrial Design and Conceptual Design: E-Business Creative Design Manufacturing, 2009
    Co-Authors: Yangping Chen, Qiang Xie, Qiulin Ding
    Abstract:

    In order to improve quality and efficiency of complex product development, the idea of design maturity is applied to control the evolution process of variable configuration item (VCI) of complex product. The method of maturity fuzzy evaluation is put forward to calculate the design maturity. Five maturity gates are applied to control the design process of VCI. The system of computer aided maturity evaluation and control for VCI is developed. The system architecture, main metadata and the key functions are described. The system was applied to manage design maturity for some civil helicopter. Compared with the traditional design pattern, the average number of part version of flight control system was reduced. The proposed method and developed system was verified.

  • Aircraft Variable configuration item Design Evolution Based on Maturity Fuzzy Evaluation
    2009 First International Conference on Information Science and Engineering, 2009
    Co-Authors: Yangping Chen, Qiang Xie, Qiulin Ding
    Abstract:

    It is difficult to consider all corresponding factors during the design cycle of aircraft. There is no effective way to control the design of evolutionary process at present. In this paper, the maturity idea and gate control are used to manage the evolution of variable configuration item (VCI) design which is the basic unit of aircraft. Index system of aircraft VCI design maturity evaluation is established. Mathematical models and evaluation algorithm of comprehensive evaluation of VCI design maturity are studied. 32 key evaluation factors are used to calculate 5 maturity gates which control the evolution of VCI design. The method is used to evaluate dynamically the evolution of VCI design in the development of some helicopter co-designed Chinese Helicopter Research & Development Institute and her partners. Compared with the traditional design pattern of flight control system, the frequency of demotion from high level to low level is decreased from 46% to 28% and the average number of part version is reduced from 2.3 to 1.4.
