Systems theory perspective

OBSERVABILITY AND PROCESS MONITORING, A SYSTEM THEORY PERSPECTIVE... 

Although the importance of a systemic perspective on metabolism has only recently attained widespread attention, a formal frameworks for systemic analysis has already been developed since the late 1960s. Biochemical Systems Theory (BST), put forward by Savageau and others [142, 144 147], seeks to provide a unified framework for the analysis of cellular reaction networks. Predating Metabolic Control Analysis, BST emphasizes three main aspects in the analysis of metabolism [319] (i) the importance of the interconnections, rather than the components, for cellular function (ii) the nonlinearity of biochemical rate equations (iii) the need for a unified mathematical treatment. Similar to MCA, the achievements associated with BST would warrant a more elaborate treatment, here we will focus on BST solely as a tool for the approximation and numerical simulation of complex biochemical reaction networks. 

Another perspective comes from famiiy systems theory, which characterizes the schizophrenic patient s family as having disordered communication, with various members playing unusual or aberrant roles. According to this theory, patients experience double binds when faced with contradictory expectations ( 7). Related controversial hypotheses held that the schizophrenogenic mother was the critical factor and then later that the schizophrenic s father also played a significant role (8, 9 and 10). Intensive therapy, in the context of in-hospital separation from the family, was considered the treatment of choice. In contrast to classic psychodynamic therapy, which focuses on the individual patient, this approach attempts to resolve conflicts in the family system, as well as in the patient s psyche. Typically, this involves sessions that include all or as many members as possible. Thus, even though one member is identified as the patient, it is the disturbed communication and interactions among all members that is the focus of therapy. This and subsequent therapeutic approaches may be most effective when medication is used concurrently. 

Abstraction is the basic concept of modeling. In system theory, we know many perspectives of abstraction. Thus, we can concentrate either on the structure or behavior of enterprises on certain elements of the enterprise, such as data, employees, software, products or on a bounded domain, such as sales, accounting, manufacturing. Typically, in enterprise modeling projects, several of these perspectives are combined. For instance, a typical modeling project might be Describe the sales data structures. ... 

We close this chapter with a brief introduction to the implications of work in dynamical systems theory for experimental design and analysis. This section is meant to portray a systems perspective that may be a fruitful worldview fi om which to approach research. The multivariate, replicated, repeated-measures, single-subject design can be used to provide data for examination within this dynamical systems perspective.

From a broader perspective, the Abnormal Situation Management Consortium is working to apply human factors theory and expert system technology to improve personnel and equipment performance during abnormal conditions. In addition to reduced risk, economic improvements in equipment reliability and capacity are expected (Rothenberg and Nimmo, 1996).
