| Summary: | 碩士 === 國立聯合大學 === 管理碩士學位學程 === 100 === In recent, the rapid development of information technology and e-health care equipment, the importance of the seniors’ e-health care issues are rasing. However, the planning of the development of e-health care for senior citizens will face many operational limitations and interactive effects among the influence factors in a complex environment. In fact, the problem of seniors healthcare is a dynamic and complex issues involved in government policy, medical technology, an aging population, the seniors use of e-health care products willingness of e-health care needs, and so on. Therefore, the system dynamics method is used in this study to explore the structure of senior citizens health care problems, to identify the causal relationship between the impact variables, and then drawn into the causal feedback map. The qualitative factors such as government policy, the willingness to use the qualitative variables of perceived ease of use, perceived usefulness, will be needed the opinions of experts or users. In gerenal the subjective judgment of experts or users are ambiguity and uncertainty. It is suitable to use the linguistic variables to represent the opinions of experts or users. Therefore, combining the system dynamics with linguistic variables in this study to construct the senior e-health care model for Taiwan. Based on the proposed model, the Vensim software is used to make the simulation. According to the simulation results, we can find out five important points. (1) In the seniors e-health care system, the linguistic variables can fully express the subjective opinions of experts or users, and then effectively deal with the computation of the qualitative variables. (2) Vendors of electronic health care product development, must consider the perceived of seniors for the ease of use and usefulness of products. It will enhance the seniors' willingness to use, and increase the sales of e-health care products. (3) Government should encourage and enhance the willingness of nurses' use of e-health care products, in order to effectively solve the problem of shortage of nursing manpower. (4) Government should actively improve the work environment of nurses to improve the turnover rate of nursing staff. (5) Accounding the reautts of the questionnaire, government shouldn’t rely solely on the maternity grant policy, but also consider the educational environment and family burden to effectively increase Taiwan's fertility rate to improve the aging of the population structure.
