Background: There is an increasing recognition that modelling and simulation can assist in the process of designing health care policies, strategies and operations. However, the current use is limited and answers to questions such as what methods to use and when remain somewhat underdeveloped. Aim. The aim of this study is to provide a mechanism for decision makers in health services planning and management to compare a broad range of modelling and simulation methods so that they can better select and use them or better commission relevant modelling and simulation work. Methods. This paper proposes a modelling and simulation method comparison and selection tool developed from a comprehensive literature review, the research team's extensive expertise and inputs from potential users. Twenty-eight different methods were identified, characterised by their relevance to different application areas, project life cycle stages, types of output and levels of insight, and four input resources required (time, money, knowledge and data). Results: The characterisation is presented in matrix forms to allow quick comparison and selection. This paper also highlights significant knowledge gaps in the existing literature when assessing the applicability of particular approaches to health services management, where modelling and simulation skills are scarce let alone money and time. Conclusions: A modelling and simulation method comparison and selection tool is developed to assist with the selection of methods appropriate to supporting specific decision making processes. In particular it addresses the issue of which method is most appropriate to which specific health services management problem, what the user might expect to be obtained from the method, and what is required to use the method. In summary, we believe the tool adds value to the scarce existing literature on methods comparison and selection.

Over the past decades simulation has been recognized as a vital tool for solving problems within the healthcare sector, almost catching up with other areas. It is evident that healthcare systems are rapidly evolving into complex and dynamic environments whilst bearing a multitude of stakeholders. Simulation has originally emerged from military and manufacturing applications that mainly follow sequential processing with pre-specified targets. Such an approach is too rigid and irrelevant to the complexity and dynamism of healthcare systems, where lack of understanding is a common feature. This is mainly attributed to lack of understating of the life cycle of healthcare services. In this paper we attempt to define the life cycle of healthcare services and explore the use of modeling and simulation in supporting healthcare service development and management. We particularly explore a number of exemplars of how modeling was used to support earlier stages of the service life cycle.@en
