For the modernized combat requirement,weapon system and associated equipments’ performance and reliability are two key issues that into account. In order to maintain the readiness of these equipments, improving maintenance technology level of armed forces equipments is much more important than before. At present,most of the maintenance technology in the field of armed forces equipments is still imported by the foreign countries. The maintenance technology transfer is getting more critical especially to the phases during maintenance capability establishment. According to the literature review,the studies related to the maintenance technology transfer are very limited.Most of these survey reports studies are mainly regarding the GOCO(government own company operate),without taking complexity or further assessment. This research takes one engine depot of ROCAF as an example, to investigate the influences and differences among maintenance technology, transfer mode, as well as it’s performance. This research conducted the questionnaire investigation, and applied the statistic analysis method. The retrieved valid questionnaires are calculated up to 291 of 362 copies, and the effective returned rate is 85.08%. The conclusions of this research show that during the engine maintenance capability establishment, there will have different technology transfer performance by different maintenance transfer modes. And selection of technology modes will be affected by different maintenance capability, motivation of technology receiving, and characteristics of maintenance technology. The maintenance technology of employees will also affect the technology transfer mode performance. In the phase of performance awareness, most of the employees supposed the way of technology manual study by themselves is better than the other two. Maybe the way of study by themselves is considered saving more time. The selection of technology transfer will be affected by maintenance technology characteristics and capability. The more complicated the technology is, the higher motivation of technology requirement. The better technology capability is, the higher awareness of performance. The results of this research can be a reference for Armed Forces to establish engine maintenance capability in the future.

With the globalization and the increased competitions among businesses in recent years, the implementation of organizational changes in various enterprises has already become the trend. "Jingjin Program"(The ROC Armed Forces Streamlining Program) was one of the decisive conducts for the Department of Defense. The purpose of the present study was to investigate the relationships among change perceptions, work attitudes, and work performance of employees in Military Aircraft Engine Maintenance Shop after implementation of Jingjin Program. Four hundred and fifteen questionnaires were distributed with a valid return rate of 69%. The findings indicated that overall, the employees had very low recognitions toward Jingjin Program. Among them, the employees with the age ranged from 20 to 29 had stronger perceptions toward “communication policies” than their counterparts since the contents of Jingjin Program have greater impacts on their future work and lives. Moreover, sergeants reported to have better work attitudes and work performance since they had greater concerns on their future career development and finance to be considered. It is also found that change perceptions did significantly affected employees’ work attitudes and work performance. Therefore, the researcher suggested that leaders, when implementing organizational changes, should acknowledge that effective communicating change policies with the employees is the key to success. By way of effective communications between organization and the employees, the change purposes could be understood and implemented. Through proper counseling, employees’ negative psychological issues could be resolved. Thus, it will lead to desirable outcomes of organizational changes.

The aviation fuel consumption has always been the key factor for the airline's operating cost. Since the amount of worldwide fuel usage for the transport aircraft is huge and the fuel cost is up surging, how to reduce the fuel consumption and the carbon emission is an urgent problem in aviation industrial circles. The objective for the present study is to show that the application of a model-based method based on flight data and FCOM (Flight Crew Operating Manuals) can provide strategies as how to enhance fuel efficiency for commercial transports. The fuel efficiency, engine health, and aircraft performance are closely related. The standard models of exhaust gas temperature (EGT) and lift-to-drag ratio (L/D) can be established by using fuzzy-logic modeling (FLM) techniques. And then, the excessive fuel consumption and optimum cruising altitude can be estimated numerically through the analysis of model-based derivatives. The excessive fuel consumption due to the effects of deficiencies will be estimated in the present study. According to the model-predicted results, if the causes on deficiency per influencing flight variable can be solved, the total potential fuel saving will be 19.2%.

Most of the researches on the models of technology transfer are focus on the relationships between the overall performance and their affecting factors of technology transfer as well as their individual performances and their affecting factors under specific technology transfer models such as FDI, Joint Venture, and Licensing. This research is to divide the mode of the weapon equipment’s maintenance technology transfer into the explicit and tacit modes of technology transfer under the licensing models. In addition, this research will discuss relationships between the individual performance of technology transfer modes and their affecting factors moer deeply for acquiring a set of model of more optimal selections of technology transfer modes on the weapon equipment’s maintenance technology transfer. Herein the methodology is to build up a study structure by means of the paper study and 3-practical-case study, then achieve a questionnaire to all maintenance technology personnel in an aircraft engine accessory overhaul center in ROCAF to prove. The result shows that the different modes of maintenance technology transfer will cause different performances of technology transfer, and also the acquisition channels, technology characteristics, the technology capability of maintenance personnel, and the motive of technology acquisition will influence selections of technology transfer modes actually.
