FRAM Model Interpreter (FMI)

Model Checking and Interpreting

The FRAM Model Interpreter (FMI) is a software tool that can be used to interpret a


FRAM model and through that determine how the described activity or task may develop.


The FMI provides a realisation or simulation of a given model in the sense that it evaluates


the consequences of the couplings specified by the aspects of the model’s functions and


thereby shows how an event can develop. The FMI can therefore be used to determine


how the potential couplings defined in the model will be realised as actual couplings for


specified conditions – an instantiation.


The current version  of the FMI (Basic Plus, updated July 12th 2019) can be found here.

It needs an externals file to be saved in the same folder which can be found here.

A manual with the basic theory and instructions for use with an example can be found here

The FMI has been developed and written by Erik Hollnagell (http://www.safetysynthesis.com). The FRAMily believes this will make a significant step forward in assisting the development of meaningful and useful FRAM models. This is particularly important in handlling some of the more extensive models of complex systems now being utilised as below.






















Please provide feedback both about the FMI and any support software ideas and share your  interesting applications and/or examples.

Rees Hill (http://www.zerprize.com) is essentially, with Erik, the lead in an active software development team (Hill, Patriarca, Smith, Slater and Comer). Any suggestions, ideas, or contrbutions are eagerly anticipated, actively encouraged and gratefully accepted.
