    In this paper, we propose a novel approach to the development of green public policies. We emphasize the significance of the system of systems (SoSs) methodology, which concentrates on understanding and managing complex systems by contemplating their interdependencies and interactions as a single integrated system. Based on this perspective, we consider green public policy as a system interacting with the energy, health, pollutants, and economic systems of the SoSs. As a method of systematic structural analysis, we use both decision-making trial and evaluation laboratory (DEMATEL) and interpretive structural modeling (ISM) techniques to understand the relationships between the systems listed above. We provide a literature review on the application of these soft operation research (SOR) techniques. We note that SOR methods are suitable for the formulation of effective public policies. Using an example, we demonstrate the primary advantage of DEMATEL and ISM, which is the establishment of easily comprehendible causal relationships between the systems in the SoSs.info:eu-repo/semantics/publishedVersio

    Dynamic resectorization to improve utility of healthcare systems

    This study discusses a regional healthcare system including several hospitals with different characteristics. We define a utility function for the system based on the sectorization concept to form a balance between hospitals in terms of important outputs such as waiting times and demands. Since the determined system is dynamic, the balance state is lost over time; consequently, resectorization is done over time. We simulate the system utilizing the data of a case study. We characterize multiple periods and calculate the utility of the system's current state. We design resectorization scenarios based on boosting the capacity and quality of hospitals. Numerical results demonstrate that substantial improvement of utility with resectorization is achievable.info:eu-repo/semantics/publishedVersio
