Software integration process of complex hardware-software systems under conditions of limited resources

A lot of problems occur during the development of complex hardware-software systems. All these problems usually caused by the system and development process specificity. In this work we present a step-by-step evolution of software development process, that took place in research lab for Mathematical Simulation of Physical Systems of Physico-Technical Research Institute of University of Nizhny Novgorod (PTRI UNN), based on continuous integration and automating software builds. We cover a set of primary issues which have arisen due to the new functionality adaptation of integration process and discuss the ways to solve its.
