In 1981, under the directing of the great scientist Qian Xuesen, an integrated frontier science— Man-Machine-Environment System Engineering (MMESE)—came into being in China. Qian Xuesen gave high praise to this emerging science. In the letter to Long Shengzhao, he pointed out, “You are creating this very important modern science and technology in China!” in October 22nd, 1993. In the congratulation letter to the commemoration meeting of 20th anniversary of establishing the Man-Machine-Environment System Engineering, the great scientist Qian Xuesen stated, “You have made active development and exploration in this new emerging science of MMESE, and obtained encouraging achievements. I am sincerely pleased and hope you can do even more to make prosper development in the theory and application of MMESE, and make positive contribution to the progress of science and technology in China, and even in the whole world ” in June 26th, 2001. In order to greatly promote the vigorous development of MMESE in the world, and realize the grand object of “making positive contribution to the progress of science and technology in China, and even in the whole world” proposed by Qian Xuesen, the 13th International Conference on Man-Machine-Environment System Engineering will take place in Yantai, China, October 21-25, 2013. The Conference Sponsor is the Man-Machine-Environment System Engineering Committee of China. Undertaker is Beijing KeCui Academy of Man-Machine-Environment System Engineering. 1981年，在伟大科学家钱学森的亲自指导下，一门综合性边缘技术科学——人-机-环境系统工程（Man-Machine-Environment System Engineering，简称MMESE）在中国诞生。钱学森对这门新兴科学给予了极高评价。他于1993年10月22日致函龙升照指出，“你们是在社会主义中国开创了这门重要现代科学技术!” 2001年6月26日，伟大科学家钱学森在致人-机-环境系统工程创立20年纪念大会的贺信中又指出：“20年来，你们在人-机-环境系统工程这一新兴科学领域进行了积极的开拓和探索，并取得了非常可喜的成绩，我感到由衷的高兴。希望你们今后再接再励，大力推动人-机-环境系统工程理论及应用的蓬勃发展，为中国乃至世界科学技术的进步作出积极贡献!” 为了极大推动人-机-环境系统工程在全世界的蓬勃发展，并实现钱学森提出的“为中国乃至世界科学技术的进步作出积极贡献”的宏伟目标，第十三届国际人-机-环境系统工程大会将于2013年10月21-25日在山东烟台召开。 本届大会由中国系统工程学会人-机-环境系统工程专业委员会主办，北京科萃人机环境系统工程技术研究院承办。
