This book describes CoSMoS (Complex Systems Modelling and Simulation) a pattern-based approach
to engineering trustworthy simulations that are both scientifically useful to the researcher
and scientifically credible to third parties. This approach emphasises three key aspects to
this development of a simulation as a scientific instrument: the use of explicit models to
capture the scientific domain the engineered simulation platform and the experimental results
of running simulations the use of arguments to provide evidence that the scientific instrument
is fit for purpose and the close co-working of domain scientists and simulation software
engineers.In Part I the authors provide a managerial overview: the rationale for and benefits
of using the CoSMoS approach and a small worked example to demonstrate it in action. Part II
is a catalogue of the core patterns. Part III lists more specific helper patterns showing
possible routes to a simulation. Finally Part IV documents CellBranch a substantial case study
developed using the CoSMoS approach.
