JAXA's Engineering Effort for Human Error Prevention
Hayama, Kazunori; Sekita, Ryuichi
In general, the solutions of hidden human factors, organization factors, and so on in the R&D fields are quite important for the root out accidents and quality problems in space development process. JAXA S&MA department publish the human errors analysis guidebook to support that solutions and give many educations using the guidebook for the motivating engineers' human errors analysis. The purposes of all these engineering efforts are to take the human error prevention activities a firm hold on JAXA's R&D process. The latest engineering attempt is the introducing the Performance Shaping Factors Management ( PSF management for short ) into JAXA's facilities maintenances process with the objective of solving the human factors personal problem. In actually JAXA's PSF management activities are just on trial phase, but JAXA has gotten good results lead to the reliability improvement from the activities. 50% decrease in working time for the propulsion piping pit clean and 10% decrease in working time for the lubricant exchange maintenance are actual improvement examples from the activities. Such a decrease in working time can lead to a reliability improvement and also can lead to a saving maintenance budget. The next attempts for the PSF management activities in JAXA are the development of R&D process including PSF management and the realizing PSF carry out system for all JAXA's facilities. This report traces the results of the past human error prevention engineering activities and also give an outline of future plan.
