Development and Operations Modeling as Information Application in Cause-and-Effect Relations Chains

The article is dedicated to modeling development and operation processes as an application of information to the functioning of the system. The application of information is described as alternation of cause- and-effect-relations chains to the information applied. The objective is to develop a formal representation and predictive explanation of the application of information, to enable accurate predictions of the impact of information obtained with developed and deployed software and implicated in altered circumstances. The distinguishing feature of the suggested research results is the mathematical character of the developed models. The authors introduces the concept of a complex state as a state that encompasses reflections of information, along with graph-theoretic models of such states in the form of potential sequences of complex states and transitions. Models of information application were represented with complex state, ports, and their transitions under information flows conditions. Such transitions are proposed to model with automata on graphs formalisms. It is proposed to use models presented to construct measure spaces of information application for activity and to solve various information pragmatics models based on that. Authors presents a novel approach to addressing issues related to information application for activity on the example of DevOps planning problem and agile system design problem.
