“…17,18 System dynamics (SD), an interdisciplinary modelling method used for representing and understanding the behaviour of complex systems, has been applied in previous research to explore LTC policy changes in Singapore and in the United States. [19][20][21] An SD model consists of a series of stocks, which represent the total people receiving a type of service at a given time, interconnected through flows, which represent the movement of people from one stock to another over time. 22 These elements of the model are described by differential and algebraic equations developed from a broad spectrum of relevant data.…”
