Mission critical systems (MCS) are complex nested hierarchies of systems, subsystems and components with defined purpose, characteristics, boundaries and interfaces, working in harmony to deliver vital organisational functionalities. Upgrading MCS performance is inevitable when capability enhancement is required or new technologies emerge. Improving MCS however is considered with certain degrees of reluctance due to their sensitive role in organisations and the potential disruptive impact of unexpected consequences of change. Innovation in MCS often appears in small steps that affect the entire system due to their highly interdependent structures. Effective management of innovation introduction in complex systems require systemic/systematic processes that involve process management and collective analysis, scoping, decision-making and R&D which relies on effective information sharing. This approach should run throughout the system and must include all aspects and stakeholders, utilising the skills and knowledge of all involved. This chapter describes the basic concepts and potential approaches that could be utilised to build intelligent systemic/systematic and collaborative environments for MCS innovation. Advances in ICT technologies provide an opportunity to access the wider sphere of knowledge and support the systemic innovation processes. Adopting systemic approaches increases process efficacy, leading to more reliable solutions, shorter development lead times and reduced costs.

“…During the past 60 years, many frameworks [6][7][8], procedures [4,9] and systems [10] were created to support designing [11] and managing the complexities of the MCSs. These efforts have had major effects on improving the three aspects of MCSs: reliability, resiliency and recovery.…”

“…Fault tolerance is the property of a system to be functional even if some of its components fail. It is a very critical issue in the design of the systems as in Air Traffic Control Systems [1,2], real-time embedded systems [3], robotics [4,5], automation systems [6,7], medical systems [8], mission critical systems [9], and a lot of others. Description of faulttolerance modeling using algebraic structures is proposed by Beckmann [10] for groups and by Hadjicostis [11] for semigroups and semirings.…”

We propose a new class of mathematical structures called(m,n)-semirings(which generalize the usual semirings) and describe their basic properties. We define partial ordering and generalize the concepts of congruence, homomorphism, and so forth, for(m,n)-semirings. Following earlier work by Rao (2008), we consider systems made up of several components whose failures may cause them to fail and represent the set of such systems algebraically as an(m,n)-semiring. Based on the characteristics of these components, we present a formalism to compare the fault-tolerance behavior of two systems using our framework of a partially ordered(m,n)-semiring.

We propose a new class of mathematical structures called (m, n)semirings (which generalize the usual semirings), and describe their basic properties. We define partial ordering and generalize the concepts of congruence, homomorphism, etc., for (m, n)-semirings. Following earlier work by Rao [19], we consider systems made up of several components whose failures may cause it to fail, and represent the set of such systems algebraically as an (m, n)-semiring. Based on the characteristics of these components, we present a formalism to compare the fault-tolerance behavior of two systems using our framework of a partially ordered (m, n)-semiring.
