As a more massive feasible and prominent tool than the complex interval-valued Pythagorean fuzzy (CIVPF) set and complex interval-valued intuitionistic fuzzy (CIVIF) set, the complex interval-valued q-rung orthopair fuzzy (CIVQROF) set has been usually used to represent ambiguity and vagueness for real-life decision-making problems. In this paper, we firstly proposed some distance measures, Yager operational laws, and their comparison method. Further, we developed CIVQROF Yager weighted averaging (CIVQROFYWA), CIVQROF Yager ordered weighted averaging (CIVQROFYOWA), CIVQROF Yager weighted geometric (CIVQROFYWG), CIVQROF Yager ordered weighted geometric (CIVQROFYOWG) operators with CIVQROF information, and some certain well-known and feasible properties and outstanding results are explored in detail. Moreover, we proposed a new and valuable technique for handling multi-attribute decision-making problems with CIVQROF information. Lastly, a practical evaluation regarding the high blood pressure diseases of the patient is evaluated to illustrate the feasibility and worth of the proposed approaches.

作为比复区间值毕达哥拉斯模糊（CIVPF）集和复区间值直觉模糊（CIVIF）集更大规模可行和突出的工具，复区间值q-梯级正交模糊（CIVQROF）集已被广泛使用来表示现实生活中决策问题的歧义和模糊性。在本文中，我们首先提出了一些距离度量、Yager 运算法则及其比较方法。此外，我们还开发了具有 CIVQROF 信息的 CIVQROF Yager 加权平均 (CIVQROFYWA)、CIVQROF Yager 有序加权平均 (CIVQROFYOWA)、CIVQROF Yager 加权几何 (CIVQROFYWG)、CIVQROF Yager 有序加权几何 (CIVQROFYOWG) 算子，以及一些众所周知且可行的算子详细探讨了属性和出色的结果。而且，我们提出了一种新的有价值的技术来处理 CIVQROF 信息的多属性决策问题。最后，对患者的高血压疾病进行了实际评估，以说明所提出方法的可行性和价值。
