choosing the green technology an effective factor in combating climate changes. One of the concerns, is the issue of environmental pollution. The cement industry, as the basis for the development of the country and having economic interests, is one of the most important sources environmental pollution. One of the disadvantages of this industry is using the energy of fossil fuels and producing more greenhouse gases in cement production. The aim of this study is to provide a model for selecting and evaluating the green technology in the clinker coolers sector in Iranian cement industry. In this regard, at first, the green technology selection model will be introduced by studying previous researches and integrates it with expert opinions in this field. So, by researching in cement production process, the clinker coolers sector was chosen as a target in this study, also the technologies used in this sector were investigated. In the next step, by using Shannon entropy and Gray VIKOR methods, the green technological options were selected and evaluated. Moreover, instead of using the linguistic variables and absolute numbers we will use Three Parameter Interval Gray Numbers.

Enterprise resource planning systems by facilitation and integration of organizations’ operations as well as leveraging the organization's operations and business activities has become an important competitive advantage for organizations. Although the appropriate choose of an ERP system can greatly contribute to the success of the organization, inappropriate selection of ERP also can lead to irreparable damages and costs. Therefore, in this study we have tried to use a multi-attribute decision-making model to evaluate and select the most appropriate ERP system. Since decision makers turn to “uncertain preferences” to evaluate the criteria and alternatives, applying Rough Set and the Gray Set theories in the context of multi-attribute decision-making models seems more logical and consistent. The findings indicate that the “total cost” a sub-criteria of product characteristics and “system technical capabilities” a sub-criteria of system requirements are the most significant criteria and the “A6” is the most significant alternative.
