1. A method for assessing resiliency of facility configuration strategies, comprising: determining organization environment factors; determining one or more desired performance metrics associated with the organization; receiving a technical model specification that defines configuration for facilities of the organization; creating a Generalized Semi-Markov process representation of the configuration; solving, by a processor, for steady-state characteristics of the created Generalized Semi-Markov process representation; and estimating one or more values respectively of the desired performance metrics based on said steady-state characteristics, wherein said resiliency is measured based on said estimated one or more values.
