The growth of economy and population together with the higher demand in energy has created many concerns for the Indian electricity industry whose capacity is at 211 gigawatts mostly in coal-fired plants. Due to insufficient fuel supply, India suffers from a shortage of electricity generation, leading to rolling blackouts; thus, performance evaluation and ranking the industry turn into significant issues. By this study, we expect to evaluate the rankings of these companies under control of the Ministry of Power. Also, this research would like to test if there are any significant differences between the two DEA models: Malmquist nonradial and Malmquist radial. Then, one advance model of MPI would be chosen to see these companies' performance in recent years and next few years by using forecasting results of Grey system theory. Totally, the realistic data 14 are considered to be in this evaluation after the strict selection from the whole industry. The results found that all companies have not shown many abrupt changes on their scores, and it is always not consistently good or consistently standing out, which demonstrated the high applicable usability of the integrated methods. This integrated numerical research gives a better “past-present-future” insights into performance evaluation in Indian electricity industry.

Agriculture has been developed in Vietnam throughout the years, together with the fertilizing industry. In fact, among those fertilizing companies there is a need to form partnership. However, successful strategic alliances require special skills, considerations and efforts in order to assure the necessary cooperation needed to harness the respective potency of each partner. Grey Theory and DEA model were applied to calculate the effectiveness of enterprises in Vietnam fertilizer industry then offer an effective way to figure out the most suitable strategic partners. Seven companies in the fertilizer industry are selected to collect realistic data from financial reports of Vietnam issued stock market in four consecutive financial years (2012-2016). The Southern Fertilizers JSC was set to be the target decision making unit (DMU). Although this research is specifically applied to the fertilizer industry, the proposed method could also be applied to other manufacturing industries.
