As one of the latest in joining the African oil-producing countries, Ghana is facing energy resource associated conflict situations between the people and government, especially in the western region communities of the country, where the oil resources are in mass production. In avoiding open conflict, it is critical to identify and understand the key factors that induce and aggravate such situations. To serve this purpose, the present research first conducts a survey on relevant literature to obtain twenty-five factors for the situation of the Western Region of Ghana and then presents a novel large group-DEMATEL approach to rank these factors considering a large stakeholder engagement in strategic decision making. Applying the proposed approach, the interrelationship among factors are examined, and then the factor system is categorized into the cause-group and effect-group based on assessments of twenty stakeholders from various backgrounds. It is suggested that all the cause-group factors (i.e., key factors) should receive considerable attention, with the highest regarded one being the “increased unemployment” factor. Compared with the traditional DEMATEL, the novel large group-DEMATEL considers large group consensus of decision makers and thus promotes large group satisfaction among people. Therefore, the sustainable evaluation results of twenty-five factors are more reasonable and acceptable using the proposed approach.

作为加入非洲产油国的最新举措之一，加纳面临着与人民和政府之间能源相关的冲突局势，特别是在该国西部地区社区，那里的石油资源正在大量生产。为了避免公开冲突，至关重要的是要识别和理解导致和加剧这种情况的关键因素。为了达到这个目的，本研究首先对相关文献进行了调查，以获取加纳西部地区局势的25个因素，然后提出了一种新颖的大型DEMATEL方法，以考虑到大型利益相关者的参与对这些因素进行排名战略决策。应用提出的方法，研究了因素之间的相互关系，然后根据来自不同背景的二十个利益相关者的评估，将因素系统分为原因组和结果组。建议所有引起原因的因素（即关键因素）都应引起足够的重视，其中最受重视的一个因素是“失业增加”因素。与传统的DEMATEL相比，新颖的大型团体DEMATEL考虑了决策者的大型团体共识，从而提高了人们之间的大型团体满意度。因此，使用所提出的方法，对25个因素的可持续评估结果更为合理和可以接受。最高的被认为是“失业增加”因素。与传统的DEMATEL相比，新颖的大型团体DEMATEL考虑了决策者的大型团体共识，从而提高了人们之间的大型团体满意度。因此，使用所提出的方法，对25个因素的可持续评估结果更为合理和可以接受。最高的被认为是“失业增加”因素。与传统的DEMATEL相比，新颖的大型团体DEMATEL考虑了决策者的大型团体共识，从而提高了人们之间的大型团体满意度。因此，使用所提出的方法，对25个因素的可持续评估结果更为合理和可以接受。
