【摘要】：文章考虑工程项目实施过程中的不确定因素,建立工期、成本、质量模糊均衡优化(FTCQP)模型;运用分解定理、强化区间线性规划(EILP)方法,求出各目标的最优值区间;进一步引入模糊偏好关系,运用模糊折衷规划法,得到FTCQP模型的最优模糊折衷解。最后通过案例分析验证了方法的合理性、有效性和可操作性。
[Abstract]:In this paper, considering the uncertain factors in the implementation of engineering projects, the fuzzy equilibrium optimization model of time limit, cost and quality is established, and the optimal value interval of each target is obtained by using decomposition theorem and strengthening interval linear programming (ILP) method.Furthermore, the fuzzy preference relation is introduced and the optimal fuzzy compromise solution of FTCQP model is obtained by using the fuzzy compromise programming method.Finally, the rationality, validity and maneuverability of the method are verified by case study.
