Cancer is a major global health issue;in 2020,there were 19.29 million new cancer cases and 9.96 million cancer deaths worldwide(Siegel et al.,2023).Despite ongoing research,chemotherapy remains the primary treatment due to its broad anti-cancer effects(Marra and Curigliano,2021).However,intravenous chemotherapeutic drugs commonly induce hematotoxicity,necessitating dose adjustments or treatment ***-induced thrombocytopenia(CIT)and neutropenia(CIN)are the primary manifestations of chemotherapy-induced hematotoxicity,which requires intervention due to the heightened risk of bleeding and infection(Blayney and Schwartzberg,2022).Currently,there are no FDA-approved treatments for CIT(Song and Al-Samkari,2023).While a CIT mouse model using 5-FU has been developed for drug evaluation(Shin et al.,2023),it lacks a comprehensive hematotoxicity assessment and the benefits of high throughput,cost-effectiveness,and ***,it is urgent to develop a high-throughput CIT model for risk assessment and safer chemotherapy strategies with clinical potential.

Powered by advanced information technology,more and more complex systems are exhibiting characteristics of the cyber-physical-social systems(CPSS).In this context,computational experiments method has emerged as a novel approach for the design,analysis,management,control,and integration of CPSS,which can realize the causal analysis of complex systems by means of“algorithmization”of“counterfactuals”.However,because CPSS involve human and social factors(e.g.,autonomy,initiative,and sociality),it is difficult for traditional design of experiment(DOE)methods to achieve the generative explanation of system *** address this challenge,this paper proposes an integrated approach to the design of computational experiments,incorporating three key modules:1)Descriptive module:Determining the influencing factors and response variables of the system by means of the modeling of an artificial society;2)Interpretative module:Selecting factorial experimental design solution to identify the relationship between influencing factors and macro phenomena;3)Predictive module:Building a meta-model that is equivalent to artificial society to explore its operating ***,a case study of crowd-sourcing platforms is presented to illustrate the application process and effectiveness of the proposed approach,which can reveal the social impact of algorithmic behavior on“rider race”.
