A company in a competitive environment that wishes to be a benchmark in the business world needs a management model that enables the development of systemic thinking on the part of its executives. The history of Science, in its present state, shows in fact that for certain situations (but not all), such a choice produces the safest information. The importance of the results obtained is a function of the activity of networks which, as for the nervous system, become observation “units.”. A system can be considered complex if its agents meet four qualifications: diversity, connection, interdependence, and adaptation. Section 3.3). When a complex system has to be managed, it is managing these distinctively complex behaviours that causes the decision problems. We believe the time has come to broaden the traditional approach to leadership and decision making and form a new perspective based on complexity science. Systemic icons, it is true, also “represent” but, as they are produced functionally, they do much more than this and can justifiably be described as cognitive icons as they enable knowledge. To use them, the decision maker is obliged to search for them on the basis of their salience (or saliency), which therefore entails the necessity of a prior mental representation. For stylistic reasons and to simplify writing, the masculine form is used in this chapter. At the core of the decision-making process is the need for quality information that allows the decision maker to better assess the impact of decisions in terms of outcomes, nonlinear feedback processes and time delays on the performance of the complex system invoked. They cannot be processed in a laboratory nor reduced to a few variables, so they must be considered as global in nature and their complexity must be taken into account. The necessary and legitimate search for the most efficient action to solve a problem, as discussed by MacCrimmon, has led researchers to design research plans inspired by the exact sciences (e.g. The value attached to the same sum of money varies in fact according to the individual fortune already possessed so that utility is a more general reference than monetary value. Decision-making in complex systems source: ... neither parametric rationality nor equilibrium-based strategic rationality helps much in the problem of decision-making within a complex adaptive system. Such a task can only be difficult. Processing difficulties become sensitive at the junctions of the different cognitive operations implemented in succession to determine the action chosen. Their increased power and accessibility have enabled the accumulation, organization, and analysis of massive amounts of data. A decision maker “observes a gap between an existing state and a desired state and has the motivation as well as the potential to reduce this gap, while more than one possibility of action exists which may not be immediately available, a kind of action requiring an irreversible allocation of resources [cognitive in this case], and while the benefits [consequences] associated with each choice are completely uncertain” [1]. Each of the end points is evaluated numerically taking its frequency into account [assessment of the probability (p) that it will take place taking uncertainty into account] and the subjective value (i.e. How should one assess, measure, or quantify the activity of a complex system with a view to predicting its development and being able to decide accordingly? A new element has been introduced into the situation: that of the interactions at all levels between different variables; interactions of a kind and extent which develop with time, the progress of the event and the measures undertaken at the previous stages by the action teams. Tacit knowledge is often used to fill the gaps in complex decision making processes. Intelligent Decision Support in Process Environments, https://doi.org/10.1007/978-3-642-50329-0_5. The outcome (leaf) which has the highest p*u numerical value is that deemed to constitute the best consequence. For contemporary psychology, decision-making represents behaviours, which are very different from automatic responses. Presents a range of practical tools and techniques for decision making in complex environments and systems; Offers an expert forecast of future directions in decision making theory and practice; see more benefits.
