Integrating Participatory Modeling with Simulation Techniques for Evidence-Informed Decision-Making in Addressing Patient Flow and COVID-19 Challenges
While simulation modeling methods are widely acknowledged as valuable tools in healthcare, their findings are rarely adopted by decision-makers in real-world policy-making. This problem arises from insufficient stakeholder engagement and the limitations of single-method simulation approaches, which …
