Organizational Reliability Capability Assessment: A Case Study in China R&D Enterprise for Aviation Products

Abstract

The IEEE Standard 1624 provides a foundation for the assessment of organizational reliability capability (ORC). However, to better match the individual characteristics of different industries, this standard needs to be suitably clipped and adjusted, so as to develop customized models for the reliability capability evaluations of different organizations. To evaluate the ORC of China's aviation enterprises effectively, we propose a reliability engineering capability maturity model ( RE-CMM) for China's aviation industry, with adequate consideration of the features closely associated with China's aviation enterprises and China's military standards. The proposed RE-CMM model is established on the theoretical basis of Capability Maturity Model Integration (CMMI), combined with the IEEE standard and China's military standards for Reliability, Maintainability, and Supportability (RMS). Structural equation modeling (SEM) is used to verify the validity of the RE-CMM model. We use a fuzzy method for the evaluation of reliability engineering capability. Detailed steps of reliability engineering capability assessment are also provided for the application of the model. Finally, a case study on a Chinese aviation enterprise is given to illustrate the model and method.Index Terms-Fuzzy integral, multiple index evaluation, reliability capability, triangular fuzzy number.

Developing a Fuzzy Multi-Criteria Evaluation Model for Prefabrication Development Maturity of Construction Firms

“…Moreover, different maturity levels reflect different aspects of capabilities and development of maturity criteria, such as prefabrication technology, management, labor, and R&D [18,31,32]. For the ranges of fuzzy integral scores corresponding to the level, these can be described in the type of triangular fuzzy number (TFN) or real number [62][63][64]. Especially, the real number type obtained better adoption in describing the precise capability level of evaluation object in [64].…”

Methods for Identifying and Controlling Weak Links in the Supplier's Product Guarantee Capability

“…The result is a list of critical tasks affecting product reliability, which can not cover the whole process and all elements. Wang Jing et al [7] proposed the concept and evaluation framework of reliability system engineering capability, but did not form a systematic quantitative evaluation mechanism; on this basis, Pan et al [8] proposed a reliability engineering capability maturity model (RE-CMM) for China's aviation industry, but it is difficult to effectively identify process defects, so as to achieve the effect of promoting improvement through evaluation.…”
