A Method to Evaluate Product Development System for Civil Aviation Power System Based on SAE ARP4754A

In response to the public's concern about the safety and reliability of civil aviation products, SAE ARP4754A was published. The international mainstream civil aircraft manufacturers and system-level and equipment-level suppliers have referred to SAE ARP4754A when establishing their own product development systems, and on this basis, they have formed system documents such as guidelines, regulations, templates, and checklists applicable to their respective products. Most of Chinese aviation manufacturers are also gradually establishing product development systems for their own products. From the perspective of a power system R&D company, this paper introduces a method of evaluating the construction and operation of the suppliers' product development system, According to this method, the evaluation activities are scored from four dimensions: R&D team, R&D tools, R&D procedures and R&D activities. After the evaluation, the scores of the four dimensions were weighted and averaged according to the set weighting, 20%, 20%, 30%, and 30%. In the end, the five suppliers, companies A, B, C, D, and E, scored 70.5, 62.4, 71.6, 68.8, and 79.0, respectively. In addition, this paper also gives some practical suggestions, such as conducting the evaluation in conjunction with the project milestone review, or scheduling the evaluation according to the progress of product development.
