In addition, comprehensive cost assessment model, important part carried out, general framework methodology accuracy explored. And then current evaluation method raises author's personal doubts. At end article, this paper names two problems is, lack basic data incomplete MCDA (Multi-criteria Decision Analysis) method. provide reference feasible research directions for future scholars who aims study especially North Sea UK point out direction improve its
