全过程工程咨询联合体内部风险分担

Research on risk sharing within the whole process engineering consulting consortium

【目的】有效分担风险,减少责任推诿,促进全过程工程咨询联合体顺利合作。【方法】从全过程工程咨询联合体的角度,建立风险因素清单和风险分担影响因素指标体系;采用基于云模型改进的层次分析法和熵权法分别计算各指标的主观权重和客观权重,用线性加权方式获得组合赋权;构建基于灰色关联分析法(grey relational analysis,GRA)耦合优劣解距离法(technique for order preference by similarity to an ideal solution,TOPSIS)的联合体内部风险分担模型(GRA-TOPSIS),按综合相对贴近度排序确定风险分担结果。【结果】将所构建的模型用于长沙市某建设项目,以工程变更风险为例选择最合适的风险分担方,研究结果与工程实际相符。基于此,通过求解确定了一套合理共担或独担风险的方案,实现了联合体内部风险的合理分担。【结论】GRA-TOPSIS模型适用于全过程工程咨询联合体内部的风险分担且具有普适性,可为联合体内部风险分担和全过程工程咨询服务模式的推进提供一定参考。

[Purposes]Effectively share risks,reduce the shirking of responsibilities,and promote the smooth cooperation of the whole-process engineering consulting consortium.[Methods]This paper establishes a list of risk factors and an index system of risk-sharing influencing factors from the perspective of the whole-process engineering consulting consortium.The subjective and objective weights of each index are calculated by using the improved analytic hierarchy process based on the cloud model and the entropy weight method,and the combination weights are obtained by using the linear weighting method.Subsequently,an internal risk-sharing model(GRA-TOPSIS)based on grey relational analysis(GRA)coupled technique for order preference by similarity to an ideal solution(TOPSIS)is constructed to determine the risk-sharing results by ranking the comprehensive relative proximity.[Findings]The model constructed in this paper is used for a construction project in Changsha,and the most suitable risk-sharing party is selected by taking the engineering change risk as an example.The result is consistent with the actual project.Then,the solution determines a set of reasonable sharing or exclusive risk schemes,which achieves the rational sharing of internal risks within the consortium.[Conclusions]The GRA-TOPSIS model is suitable for the internal risk-sharing of the whole process engineering consulting consortium and has universality,which can provide a certain reference for the promotion of the internal risk-sharing of the consortium and the whole process engineering consulting service model.
