当前,季节性、时段性电力供需矛盾日益凸显,通过避峰、错峰、限电等措施开展的有序用电在一定程度上能够缓解电力供需紧张局势,更好地保障电力系统的平稳运行。在此背景下,提出一种基于熵权—灰色关联变权重的有序用电决策方法。首先,... 当前,季节性、时段性电力供需矛盾日益凸显,通过避峰、错峰、限电等措施开展的有序用电在一定程度上能够缓解电力供需紧张局势,更好地保障电力系统的平稳运行。在此背景下,提出一种基于熵权—灰色关联变权重的有序用电决策方法。首先,克服单一常权重对异常指标不能灵敏反应的缺陷,将信息熵与灰色关联度相结合引入可变权重,对用户参与有序用电的潜力进行综合评估,以此确定企业参与有序用电优先级。然后,为避免传统人为编排有序用电方案导致收益损失,提出有序用电辅助决策方法,并基于MATLAB仿真模拟用户避峰、错峰等操作。最后,以长沙市黑石线2020年迎峰度夏运行方案为例验证决策方法的准确性与有效性。仿真结果表明,所提出的基于信息熵-灰色关联变权重的有序用电辅助决策方法,能够有效缓解高峰期电网调峰压力,具有一定的经济性与工程实践价值。 展开更多

For the last two decades, there has been an ongoing research concerning the international new ventures (INV) or born global (BG) companies which are rapidly entering foreign markets. They face challenges connected with their marketing activity, because they launch relatively more product innovations in a shorter time than the gradually internationalized companies (GRAD). The entrepreneurial marketing (EM) concept could become a solution to some of these challenges, because of a greater entrepreneurial intensity (EI) and different decision-making approach than "classical" marketing concept. This study's aim is to analyze the EM concept and application of its elements by the INVs originating from Poland. Based on two computer-aided telephone interview (CATI) studies of INVs from the Polish industrial processing sector, the central elements of EM, applied by them, are explored, together with their relationship to INV performance. As it is shown, the INVs introduce significantly more product innovations than the gradually internationalized small and medium sized enterprises (SMEs). They often exceed competitors in the speed of launching innovations and are flexible in entering new markets. The entrepreneurial orientation (EO) indicators are at low to medium levels in all studied SMEs. However, the propensity to risk is slightly stronger in the INVs and correlated moderately with the financial performance. As the study shows, lack of emphasis on marketing planning and information gathering is the characteristic of the Polish INVs, which may testify to their effectual approach to decision making. Furthermore, similar as in the foreign-based INVs, there may exist a relationship between the application of the EM concept and performance of the Polish INNs, which, however, requires further study with respect to some mediating factors. It has been concluded that innovativeness of the product offering and propensity to risk seems to be the characteristic EM concept elements accompanying the rapid internationalization of INVs. The future research should focus on other elements of the EM-mix applied by INVs originating from emerging economies. 展开更多
