“…The 21st century landscape is defined by themes of ambiguity -increasing lack of clarity and situational understanding, complexity -large numbers of richly interdependent and dynamically interacting systems with behaviour difficult to predict, emergence -inability to deduce behaviour, structure, or performance from constituent elements, interdependence -mutual influence among complex systems through which the state of a system influences and is influenced by, the state of interconnected systems and uncertainty -incompleteness in understanding, predicting, or controlling of systems (Flood and Carson, 1993;Skyttner, 2005;Katina et al, 2014aKatina et al, , 2014b. Under such conditions, organisations must be viewed as complex interdependent systems rather that simple and isolated systems (Hammond, 2002;Laszlo, 1996).…”

Abstract:The purpose of this paper is to develop a systems theory-based construct for pathologies within the context of complex system problem formulation. Problem formulation is arguably one of the most critical phases of any endeavour to improve systems. However, there is relatively little research utilising systems theory during problem formulation. A possible extension of the systems research is the introduction of systems theory (i.e., laws, principles and concepts) as a foundation for exploration, innovation, transformation, evaluation and evolution of complex systems. Specifically, this paper is concerned with how we might use systems theory to articulate pathologies -circumstances, conditions, factors, patterns and/or issues acting to impede system performance. The paper examines the importance of problem formulation for issues related to complex systems. A multidisciplinary literature review is then provided to synthesise insights on pathologies. A systems theory-based construct for pathologies is then developed. Finally, the paper provides implications for the systems theory-based pathologies construct related to complex system governance. The paper concludes with possible future research directions.Keywords: complexity; construct; interdependence; management cybernetics; metasystem pathology; problem formulation; system pathology; systems theory; viable system model; VSM.Reference to this paper should be made as follows: Katina, P.F.

“…Third, the operating landscape/environment for Smart Grids is characteristically complex, involving a range of socio and technical issues [92]. The articulation of the current state of the Smart Grids problem domain can be characterized consistent with earlier works [45,46,[48][49][50][51] and the notion of 'messes' by [1] as well as 'wicked problems' by [74]. Table 5 provide articulates characteristics of a landscape from which Smart Grids are projected to operate.…”

Smart Grids offer higher level capabilities intended to meet current and future energy demands. These demands include improved performance related to concepts of reliability, resiliency, environmentally friendly generation, transmission, and distribution as well as turning consumers into prosumers. This study focused on two primary objectives: (1) to understand how the concept of risk is currently being addressed in Smart Grids, and (2) to suggest a more holistic view of risk for Smart Grids. Pertinent literature on Smart Grids was collected and synthesized for the concept of risk which indicated the prevalence of two factors, probability and consequence, as the main factors for Smart Grid risk quantification. However, it was discovered that current literature appears to focus on risk within the different domains of Smart Grids (i.e., generation, transmission, distribution, customer, service provide, operations, markets) without consideration Smart Grids as an integrated whole. A criticality-based approach (CBA) is proposed and then used as the basis for development of an extended listing of measures, including dependency, interdependency, and resiliency, as well as accepted risk factors (i.e., probability and consequence). This confluence of factors can be utilized in a holistic Smart Grid analysis. Implications for CBA and future research directions for realizing enhanced Smart Grid capabilities are provided

“…In contrast, a SoS does not have a defined lifecycle, is resistant to stable requirements definition, and can evolve rapidly without a single solution emerging. This tenuous nature of SoS amplifies as constituent systems add, modify, or drop, based on the continuing need for the SoS to fulfill a mission (Katina et al 2014). In short, the stability necessary for traditional systems engineering does not exist for SoSE.…”

Systems theory (ST) can provide the developing systems of systems engineering (SoSE) field and practice with a strong conceptual foundation. ST is presented as a taken for granted set of axioms and corresponding propositions that explain the phenomena, patterns, and tendencies of complex systems. The results of ST are observable in the behavior and performance of systems. We argue that ST offers a critical grounding for the future development and practice of SoSE. Our exploration examines the necessity, contributions, and implications of ST as an influential conceptual foundation to accelerate and guide SoSE development and practice.
