Modern social mobilization systems are becoming increasingly complex, leading to significant uncertainty in the mobilization process. This paper introduces the concept of "Effective Response Dimension" to quantify the complexity of mobilization systems, namely the number of key decision-making nodes in the mobilization system (truncation dimension, k_t) and the order of collaboration among mobilization departments (superposition dimension, k_s). Utilizing flexibility's ability to quickly adapt to changes and modularly reorganize resources, this study reduces the effective response dimension or provides compensation, conducts more comprehensive simulation assumptions for resource allocation, process regulation, and social collaborative mobilization, suppresses the growth of uncertainty, and generates more accurate mobilization decisions.
