Analysis of the Stakeholder Engagement in the Deployment of Renewables and Smart Grid Technologies

引用

Journal of Electronic Science and technology 2015年第3期13卷 221-228页

作者： Valeriia Vereshchagina Mario Gstrein Bernd Teufel International institute of management in technology University of Fribourg the International institute of management in technology University of Fribourg

The implementation of higher shares of renewables in a global energy mix has to be accompanied by simultaneous deployment of enabling smart grid technologies （SGTs）. This combination will inevitably lead to a revolutionary change in a conventional energy system, particularly, the shifting role of consumers to prosnmers. But resistance may arise from such a dramatic shift, since it is associated with high uncertainty in conjunction with increasing responsibilities of all stakeholders, the urgent need of effective control, and the development of a process. To ensure the positive influence, coherent actions of all players, and appropriate treatment of the spots of resistance, the analysis of the interplay between key stakeholders has been done. The paper introduces the framework for stakeholders＇ analysis, applies it on the European Union （EU） example, and provides recommendations to reduce the resistance of SGTs deployment.

An evolutionary model of urban bus transport network based on B-space

引用

Chinese Physics B 2008年第8期17卷 2874-2880页

作者：朱振涛周晶李平陈星光 School of management and Engineering Nanjing University School of Economics and management Nanjing Institute of Technology Department of Basic Sciences Nanjing Institute of Technology

In this paper, an evolutionary model of bus transport network in B-space is developed. It includes the effect of the overlapping ratio of new route on network performance and overcomes the disadvantage, i.e. lack of economic consideration, in the evolutionary bus transport network model in P-space proposed by Chen et al （2007）. The degree distribution functions are derived by using the mean-field method and the master equation method, separately. The relationship between the new stop ratio of a route, λ, and the error in exponential of degree distribution function from the mean-field method is developed as ASlope= λ/（1 -λ）＋ ln（1-λ）. Finally, the bus transport networks of Hangzhou and Nanjing are simulated by using this model, and the results show that some characteristic index values of the simulated networks are closer to the empirical data than those from Chen＇s model.

Gastroprotective effect of the iridoid fraction from Barleria prionitis leaves on experimentally-induced gastric ulceration

引用

Chinese Journal of Natural Medicines 2014年第10期12卷 738-744页

作者： Sunil K.Jaiswal Mukesh K.Dubey Sanjib Das Ch.V.Rao Department of Pharmacy Rameshwaram Institutes of Technology & Management Department of Pharmaceutical Sciences Dibrugarh University Pharmacognosy & Ethnopharmacology Div. National Botanical Research Institute (CSIR)Rana Pratap MargLucknow 226001Uttar PradeshIndia

AIM: To study the gastroprotective effect and in vivo antioxidant potential of a standardized iridoid fraction from B. prionitis leaves(BPE) against different gastric ulcer models in rats. METHOD: The standardized iridoid fraction from BPE at 50, 100, and 200 mg/kg body weight was administered orally, twice daily for 5 days for prevention from aspirin, ethanol, cold-restraint stress(CRS), and pylorus ligation(PL)-induced ulcers. Estimation of the antioxidant enzyme activity was carried out in a CRS-induced ulcer model, and various gastric secretion parameters including volume of gastric juice, acid output, and pH value were estimated in the PL-induced ulcer model. RESULTS: BPE showed a dose-dependent ulcer protective effect in PL(18.67%–66.26% protection), aspirin(24.65%–63.25% protection), CRS(20.77%–59.42% protection), and EtOH(16.93%–77.04% protection)-induced ulcers. BPE treatment in PL-rats showed a decrease in acid-pepsin secretion, and enhanced mucin and mucosal glycoproteins. However, BPE reduced the ulcer index with significant decrease in LPO(P < 0.01–0.001), SOD(P < 0.01–0.001), and an increase in CAT(P < 0.01–0.001), activity in the CRS-induced model. CONCLUSION: The data shows that the iridoid fraction from BPE possesses anti-ulcerogenic and antioxidant potential.

Success probability orientated optimization model for resource allocation of the technological innovation multi-project system

引用

Journal of Systems Engineering and Electronics 2016年第6期27卷 1227-1237页

作者： Weixu Dai Weiwei Wu Bo Yu Yunhao Zhu School of management Harbin Institute of Technology institute of Spacecraft Systems Engineering China Academy of Space Technology

A success probability orientated optimization model for resource allocation of the technological innovation multi-project system is studied. Based on the definition of the technological innovation multi-project system, the leveling optimization of cost and success probability is set as the objective of resource allocation. The cost function and the probability function of the optimization model are constructed. Then the objective function of the model is constructed and the solving process is explained. The model is applied to the resource allocation of an enterprise's technological innovation multi-project system. The results show that the proposed model is more effective in rational resource allocation, and is more applicable in maximizing the utility of the technological innovation multi-project system. © 2016 Beijing institute of Aerospace Information.

作者： Fanyong MENG Qiang ZHANG School of management Qingdao Technological University School of management and Economics Beijing Institute of Technology

This paper is mainly to discuss cooperative games on convex geometries with a coalition structure, which can be seen as an extension of cooperative games with a coalition structure. For this kind of games, the cooperation among unions and within each union will be the convex sets, i.e., the feasible subsets of the coalition structure and that of each union belong to a convex geometry, respectively. The explicit form of the generalized Owen value for this kind of games is given, which can be seen as an extension of the Owen value. Eklrthermore, two special cases of this kind of games are researched. The corresponding Davoff indices are also stHdied. Fin~.llv ~n ilhl^r~＇i, ~r^l~ to ~

Crowd Energy management: New Paradigm for Electricity Market

引用

Journal of Electronic Science and technology 2015年第3期13卷 195-205页

作者： Mario Gstrein Stephanie Teufel the International institute of management in technology University of Fribourg

The traditionally centralized approach of electricity networks is progressively undergoing a shift towards a decentralized, distributed structure. The local and crowd-based principle is transforming the existing supply chain and related activities into a value network （VN）. Previous researches on crowd value network concepts focus on the activities of infrastructure and load management and neglect activities that generate collaboration. Collaboration with and within crowds particularly demands a different mindset and management of sharing values, information, benefit, and risks. Furthermore, these concepts must integrate technical, processual, and social aspects. Thus, this article proposes a holistic framework of electricity VN management for crowd energy. It redefines VN activities for infrastructure and load management while appending VN activities for social electricity handling. Additionally, the framework illustrates the interactions among these three elements and concludes with an adaption cycle for the crowd value network.
