Purpose： This paper proposes an expert assignment method for scientific project review that considers both accuracy and impartiality. As impartial and accurate peer review is extremely important to ensure the quality and feasibility of scientific projects, enhanced methods for managing the process are needed. Design/methodology/approach： To ensure both accuracy and impartiality, we design four criteria, the reviewers＇fitness degree, research intensity, academic association, and potential conflict of interest, to express the characteristics of an appropriate peer review expert. We first formalize the expert assignment problem as an optimization problem based on the designed criteria, and then propose a randomized algorithm to solve the expert assignment problem of identifying reviewer adequacy. Findings： Simulation results show that the proposed method is quite accurate and impartial during expert assignment. Research limitations： Although the criteria used in this paper can properly show the characteristics of a good and appropriate peer review expert, more criteria/conditions can be included in the proposed scheme to further enhance accuracy and impartiality of the expert assignment. Practical implications： The proposed method can help project funding agencies （e.g. the National Natural Science Foundation of China） find better experts for project peer review. OriginaUty/value： To the authors＇ knowledge, this is the first publication that proposes an algorithm that applies an impartial approach to the project review expert assignment process. The simulation results show the effectiveness of the proposed method.

南天山位于塔里木—卡拉库姆板块和伊犁-哈萨克斯坦板块的碰撞造山带.前人研究表明,该区在古生代经历了洋盆的扩张、俯冲消减和碰撞造山;中生代则进入到陆内发展阶段.但由于该区特殊的地理位置和复杂的构造背景,洋盆的闭合时间及盆地演化的阶段依然存在诸多争论.在广泛收集地质资料的基础上,对我国境内南天山地层大区进行了地层分区,并对每个分区的古生代-中生代盆地沉积序列进行了详细分析,最终划分出5个演化阶段:寒武纪-奥陶纪,南天山洋从有限洋盆发展为成熟洋盆,洋盆性质为弧后盆地;早志留世,南天山洋盆开始俯冲消减,东部红柳河段洋盆在早泥盆世闭合,而西部的俯冲消减则延续至泥盆纪晚期;石炭纪-早二叠世,西部仍存在残余海盆.中二叠世,残余海盆消失,南天山西部碰撞造山,南天山造山带最终形成;中生代,该区进入陆内发展阶段,在三叠纪接受剥蚀夷平;侏罗纪,西部发展成为断陷盆地,东部继续接受剥蚀夷平;白垩纪,西部延续侏罗纪断陷盆地特征,东部则发育成拉分盆地.
