Prof Dorje, Tibetan, an academician of the Chinese Academy of Engineering, an alternate member of the 17th CPC Central Committee, once served as vice chairman of the Standing Committee of the People's Congress of Tibet Autonomous Region, and a geology expert. He has long been engaged in geothermal, mineral, hydrological, engineering, environmental geological exploration and scientific research in Tibet. He participated in the exploration and evaluation of shallow geothermal storage resources in Yangbajing Geothermal field in Tibet, was responsible for the evaluation of deep high-temperature resources in Yangbajing Geothermal field, established a high-temperature geothermal system model of Yangbajing in Tibet, and put forward a new theory on the formation of high-temperature geothermal system and the migration of thermal fluids in metamorphic core complex systems. He successively served as the chief engineer of the Tibet Geological Prospecting Bureau and the Tibet Land and Resources Department. He was fully responsible for the technical management of geological prospecting in Tibet, and discovered and evaluated a number of large and super large polymetallic deposits in Tibet, making positive contributions to the innovation of geological theory and breakthrough in geological prospecting of the Qinghai-Tibet Plateau. He was awarded the Li Siguang Geoscience Prize in 2003, the highest honor in geological science in China, the “National May 1st Labor Medal” in 2004, the National Labor Model in 2005, and the “Science and Technology Innovation Award” of the He Liang and He Li Foundation in 2019.
Plenary title: Geothermal Resources and Green Utilization in Tibet
Abstract: With the continuous improvement of economic and social development level in Tibet Autonomous Region, the demand for energy is increasing, and the contradiction between energy supply and demand is becoming more and more prominent. Tibet is located in the region of severely cold and high elevation with harsh environment. Due to special geographical location and ecological environment, the use of traditional energy resources causes damage to the fragile ecological environment. Moreover, geothermal resources is abundant in Tibet Autonomous Region where geothermal reserves ranking the first in China. Therefore, the utilization of geothermal resources in Tibet has a unique advantage.
Geothermal energy is a green, low-carbon, safe, efficient, stable, versatile and potential renewable energy. According to the geographical location of the geothermal resources in Tibet, the geothermal resource should be developed and utilized through theoretical, methodological and technological innovation in accordance with local conditions. In addition to geothermal power generation, thermal drainage after power generation can also be used for heating, planting, breeding, tourism and other comprehensive utilization, and its economic, social and environmental benefits are far greater than that of simple power generation. The effective utilization of geothermal resources in Tibet can solve the problems of green power and heat supply, and alleviate the contradiction between energy supply and demand under the condition of protecting the environment. It will contribute to the sustainable development of Tibetan society and economy, and provide China's solutions for the efficient utilization of geothermal resources in the world.

Plenary title: Remanufacturing and Supply Chain Management: Dynamics between Original Equipment Manufacturers and Third Party Remanufacturers
Abstract: Remanufacturing saves costs, reduces waste, and therefore realizes environmental benefits. The remanufacturing business has attracted many third-party remanufacturers (TPRs). Remanufactured products may steal the market from the new products provided by original equipment manufacturers (OEMs) due to the substitutability. Previous empirical study showed that the presence of TPR-remanufactured products, without authorization, will enhance the valuation for new products. On the other hand, the OEM authorization will enhance the perceived value of remanufactured products from the TPR but may trigger quality concerns for new products. This paper investigates the impact of authorization on the OEM and TPR’s pricing decisions and further discusses the conditions under which both parties are willing to accept authorization. When TPR remanufacturing cannot survive when unauthorized, it is interesting to see that authorization can always help to create the TPR business and help the OEM make more profit as long as remanufacturing can benefit the centralized system, in which the OEM and TPR belong to a single enterprise. However, authorization cannot lead to system optimality not matter if TPR remanufacturing can survive without authorization. Furthermore, this research studies the optimal price and production quantity of new and remanufactured products with a two-stage model under both scenarios under which the remanufacturing is conducted by the OEM or by the TPR. A non-cooperative game model is used at the second stage when the TPR conducts remanufacturing. The models consider both the impact of the product life cycle through the market growth factor at the second stage and the influence of consumers’ perceived value of new and remanufactured products, which depends on the identity of the remanufacturer. Both theoretical and numerical analyses show that both the life cycle phase and consumers’ perception have an impact on the OEM’s decision whether to allow the TPR in the remanufacturing business. The results also reveal that the market may not be efficient for maximizing environmental sustainability and societal equity. Governments may need to interfere with the market in order to promote the TPR manufacturing, especially when the product is at the mature or declining phases of its life cycle.
