abstract = {This research presents two new Yager's ordered weighted aggregation operators using interval-valued    q-rung picture fuzzy (Ⅳ-   q-RPF) knowledge, namely the interval-valued    q-rung picture fuzzy Yager ordered weighted averaging operator (Ⅳ-   q-RPFYOWAO) and the interval-valued    q-rung picture fuzzy Yager ordered weighted geometric operator (Ⅳ-   q-RPFYOWGO). A pair of novel score and accuracy functions for interval-valued    q-rung picture fuzzy numbers (Ⅳ-   q-RPFNs) is formulated. A step-by-step process is designed to solve multi-attribute decision-making (MADM) problems using the proposed methods in Ⅳ-   q-RPF settings. In addition, these methods are efficiently applied to solve the MADM problem of identifying an optimal spacecraft shielding material against cosmic radiation. A detailed comparative study is presented to illustrate the validity of the suggested techniques in comparison with the existing knowledge.}
