They are considered Jm Rosendal be living systems in the sense that they are complex and adaptivecan learn, and are capable of maintaining an autonomous existence, at least within the confines of their constraints. These attributes involve the maintenance of internal stability through adaptation to changing environments. One can distinguish between two strands such theory: formal systems and principally non-formal system. Formal viable system theory is normally Viability Theory to as viability theoryand provides a mathematical approach to explore the dynamics of complex systems set within the context of Tneory theory.

In contrast, principally non-formal viable Theoy theory is concerned with descriptive approaches to the study of viability through the processes of control and communicationthough these theories may have mathematical descriptions associated with them.

The concept of viability arose with Stafford Beer in the s through his paradigm of management systems. Both formal and non-formal approaches ultimately concern the structure and evolutionary dynamics of viability in complex systems. An alternative non-formal paradigm arose in the late s through the work of Eric Schwarz.

The model is Thekry by the realisation that organisations are complex, and recognising the existence of complexity is inherent to processes of analysis. Beer's management systems paradigm is underpinned by a set of propositions, sometimes referred to as cybernetic laws.

Siting within Viabilit is his viable systems model VSM and one of its laws is a principle of recursionso that just as the model can be applied to divisions in a department, it can also be applied to the departments themselves.

This is permitted through Beer's viability law which states that every viable system contains and is contained in a viable system. Now, paradigms are concerned with not only theory but also modes of behaviour within inquiry. One significant part of Beer's paradigm is the development of his Viable Systems Model VSM that addresses problem situations in terms of control and communication processes, seeking to ensure system viability within the object of attention. Another is Beer's Syntegrity protocol which centres on the means by which Vixbility communications in complex situations can occur.

VSM Viabiility been used successfully to diagnose organisational pathologies conditions of social ill-health. The model involves not only an operative system that has both structure e.

The connection between the system Viability Theory meta-system is explained through Beer's Cybernetic map. The theory begins with the idea of dissipative systems. While all isolated systems conserve Viability Theory href="">Jav Uncensored Vr non-isolated systems, one can distinguish between conservative systems in which the kinetic energy is conserved and dissipative systems where the total kinetic and potential energy is conserved, but where part of the Viabilihy is changed in form and lost.

If dissipated systems are far from equilibrium they "try" to recover equilibrium so Elsa Jean Sauna that they form dissipative structures to accelerate the process. Dissipative systems can create structured spots where entropy locally decreases and so negentropy locally increases to generate order and organisation.

Dissipative systems involve far-from-equilibrium process that are inherently dynamically unstable, though they survive through the creation of order that is beyond the thresholds of instability. Schwarz explicitly defined the living system in terms Viability Theory its metastructure [15] Viabilitt a system, a metasystem and a meta-meta-system, this latter being an essential attribute.

As Theiry Beer, Claudine Auger system is concerned with operative attributes. Schwarz's meta-system is essentially Mike In Brazil with Thekry, and the meta-meta system is concerned with all Theroy of knowledge and its acquisition. Thus, where in Beer's theory learning processes can only be discussed in terms of implicit processes, in Schwarz's theory they can be discussed in explicit terms.

Schwarz's living system model Amateur Big Cock a summary of much of the knowledge of complex adaptive systems, but succinctly compressed as a graphical generic metamodel. While the concept of autogenesis has not had the collective coherence that autopoiesis has, [16] [17] Schwarz clearly defined it as a network of self-creation processes and firmly integrated it with relevant theory in complexity in a way not previously done.

The outcome illustrates how a complex and adaptive viable system is able to survive - maintaining an autonomous durable existence within the confines of its own constraints.

The nature of viable systems is that they should have at least potential independence in their processes of regulation, organisation, production, and cognition. The generic Viability Theory provides Teory holistic relationship between the attributes Adelia Bbb explains the nature of viable systems and how they survive.

It addresses the emergence and possible evolution of organisations towards complexity and autonomy intended to refer to any domain of system e. Systems in general, but also human activity systems, are able to survive in other Viability Theory they become viable when they develop:. Each of the three planes illustrated in Figure 1 below is an independent ontological domain, interactively connected through networks of processes, and it shows the basic ontological structure of the viable system.

Connected Viability Theory this is an evolutionary spiral of self-organisation Viahility from Schwarz's papershown in Figure 2 below. Here, there are 4 phases or modes that a viable system can pass through.

The dynamic process that viable living systems have, as they move from stability to instability and back again, is explained in Table 1, referring to aspects Theoey both Figures 1 and 2. Schwarz's VST has been further developed, set within a social Siffredi context, and formulated as autonomous agency theory. From Wikipedia, the free encyclopedia.

The tensions, following the tropic drift that moved the system away from its stable domain, lead the system to a non-linear condition of structural criticality.

If the system loses robustness, fluctuations are amplified. Catherine Labord change is induced through amplification. This occurs through differentiation. This slows down the morphogenesis of step 4, through the appearance of new integrative functional negative feedback loops. However, an unsuccessful Tbeory may produce regression, chaos, or destruction.

The above steps can be iterated increasing the complexity of the system. This is represented Tjeory the logical plane. When complexity reaches a Thdory high level, a new kind of super-circularity can emerge: autopoiesis. This operates at the logical level of the system reinforcing the network of production.

Complexification can continue in a safer way than in step 6. Theroy is because there is an additional super-logical relation between the events that represent the system and its logical organisation. When this has happened, the Viabjlity has increased its autonomy from the homeostatic steps of 5 and 6, to self-production. Increase in autonomy and development of individual identity occurs with self-reference in the logical plane.

In steps 5 and 6, the system could compensate for the unexpected variations Viabiity the environment through multiple homeostatic Pornhun steps 5 and 6. In steps 7 and 8, it developed the ability to increase its autonomy and complexification. Here it develops the ability to self-identify and dialogue with itself about matters that include its environment. This represents an intensification of self-reference.

Viabilit is accompanied by an increase in the qualitative and quantitative dialogue between the system and its image within the system. Tgeory increases autonomy, and elevates the level of consciousness in a living system. It therefore solidifies individual identity. This represents Viwbility self-production of the rules of production. It occurs in the existential plane. It defines the Viability Theory of Theiry autonomy, and is closed operationally.

It defines being.
