Mathematical modelling and simulation of the complex social-technical and enterprise systems lifecycles

The paper presents an approach to model and simulate the complex systems consisting of the hierarchy of interacting business agents. The approach is developed to govern or manage such business system employing definition and figuring out economic indicators of the system. The set of mathematical models proposed based on lifecycle concept and stochastic processes theory. The implementation of the models to govern large systems integrator and consulting company is described as an exemplar case.
