Abstract
Infrastructure systems, such as those that generate and transmit energy, process waste water and enable the transportation of people and goods, provide fundamental services that underpin modern society. The simulation model integration framework (smif) is an open source Python package which supports the coupling and running of infrastructure simulation models as a system-of-systems. smif connects individual simulation models – written in different programming languages and using different methods of data input and output – allowing users to compose a system-of-systems with explicit configuration of the connections and data transformations between models. Users can then run system-of-systems models using various data sources in order to explore the effects of uncertainty in external factors and model parameterisations, and to test alternative approaches to long-term decision-making and planning across the connected models. Funding statement: EPSRC programme grant EP/N017064/1 .

The simulation model integration framework is a software tool that supports the configuration, coupling, running and orchestration of infrastructure simulation models as a system-of-systems. smif has been developed to support the coupling of detailed high-resolution engineering models of infrastructure systems at the national scale to explore infrastructure performance under alternative planning strategies and future scenarios
Summary
Infrastructure systems, such as those that generate and transmit energy, process waste water and enable the transportation of people and goods, provide fundamental services that underpin modern society. Energy, solid waste, water supply and digital communications have been coupled using smif within the broader framing of the Infrastructure Transitions Research Consortium’s Assessment Process to build the second-generation National Infrastructure Systems Model (NISMOD 2). This builds on the work from the first ITRC programme which is described in [6]. To add a new model to the smif model library, developer users write a Python wrapper class implementing SectorModel These plugin wrappers are concerned with the mechanics of running each simulation model: passing in data and parameters; running the program or module; and parsing outputs to be passed back to smif. (2) Availability Operating system Cross-platform 64-bit (currently tested on Windows Server 2012 R2 and Ubuntu Trusty 14.04, in use on Windows/Mac/Linux)
