The aim of this paper is to look at some important educational aspects of complexity decision making m a mummsc^pnnary manner from the perspective of General Systems Theory (GST). First, the major issues involved in complexity management and decision making are summarized as they are viewed in literature, and a review of GST and Systems Thinking is given. The discussion in the paper is developed within the context of GST in general, but concentrated on decision making in the three trends of GST: Operations Research, Cybernetics, and Managerial Cybernetics. Here, the role of Cybernetics in complexity decision making is particularly emphasized. The discussion is then extended to the latest developments in complexity decision making in Science of Complexity and Soft Systems Thinking. The study also includes a framework which is expected to guide instructors who are planning to offer contemporary courses on decision making. The framework provides some clues for assessing the level of complexity for a given situation and selecting the appropriate methodology for solution development. 展开更多

In this paper we provide a unified framework for consensus tracking of leader-follower multi-agent systems with measurement noises based on sampled data with a general sampling delay. First, a stochastic bounded consensus tracking protocol based on sampled data with a general sampling delay is presented by employing the delay decomposition technique. Then, necessary and sufficient conditions are derived for guaranteeing leader-follower multi-agent systems with measurement noises and a time-varying reference state to achieve mean square bounded consensus tracking. The obtained results cover no sampling delay, a small sampling delay and a large sampling delay as three special cases. Last, simulations are provided to demonstrate the effectiveness of the theoretical results. 展开更多

This paper deals with the robust stabilization and passivity of general nonlinear systems with structural uncertainty. By using Lyapunov function, it verifies that under some conditions the robust passivity implies the zero-state detectability, Furthermore, it also implies the robust stabilization for such nonlinear systems. We then establish a stabilization method for the nonlinear systems with structural uncertainty. The smooth state feedback law can be constructed with the solution of an equation. Finally, it is worth noting that the main contribution of the paper establishes the relation between robust passivity and feedback stabilization for the general nonlinear systems with structural uncertainty. The simulation shows the effectiveness of the method. 展开更多

Any complex system interacts with its changing environment and its viability depends on its adaptability. The number of arbitrary coefficients in the structure of equivalent equations of complex system changes in the process of learning. In systems with more than six variables, the number of arbitrary coefficients increases first, and then, passing through the maximum, begins to decrease. This phenomenon makes it possible to explain the processes of system growth, complication and death in biological, economical and physical-engineering systems. The author uses the Linguo-combinatorial method of investigation of complex systems, in taking key words for building equivalent equations. This phenomenon is able to increase the adaptability of different systems. 展开更多

Nowadays, new paradigm of enterprise organization i s constantly changing due to the emergence of the global marketplace, the rise of information technology, and the emphasis of the social developments. This re quires a more flexible form of organization that are more adaptable to rapid cha nges in business environment such as autonomous work groups (AWGs) in order to achieve higher productivity and effectiveness. AWGs are work units responsib le for the production of goods and the provision of services. They involve team members in making decisions that are traditionally the responsibility of the sup ervisors and managers (Cohen & Bailey, 1997). Team members of AWGs are allowed t o self-regulate their behavior on jobs such as task assignments, methods for ca rrying out the work, and scheduling of activities etc. (Cohen & Ledford, 1994). For example, Motorola achieved a high organizational performance due to the succ essful implementation of AWGs in quality management (Piczak & Hauser, 1996). Xer ox also reported their operational successes based on the team-oriented work gr oups (Wageman, 1997). In recent years many organizations have replaced the traditional layers of manag ement with autonomous team-based work arrangements. Surveys indicated that the adoption of AWGs has soared in responding to the competitive business challenges . Many enterprises are making a deliberate effort to use AWGs to carry out work and operational processes as an alternative for hierarchical approaches (Lawler et al., 1995). There is a growing body of evidence that AWGs are more effective than traditionally managed groups and they contributes to organizational perform ance, such as improvement in operational performance, productivity, quality, cos t savings, employee attitude and behavior, and employee satisfaction (e.g. Pears on, 1992; Cohen & Ledford, 1994; Seers et al. 1995). Given the complexity and cognitive nature of team-based organizations, the mech anisms that the enterprises use in the development of the increasingly sophistic ated models, which can contribute to the effective functioning of AWGs, are extr emely important. The process of developing effective AWGs enables enterprises to inherent built-in intelligence of the organizations so that they will be more able to accommodate to external pressures and changes. The context of this paper is the construction of a dynamics framework and a stra tegic path for autonomous work groups in the technology-oriented manufacturing organization re-design. The framework is a conceptual one drawn from the litera ture survey. The importance of studying autonomous work groups for today’s manuf acturing organizations is claimed. Based on the General System Theory (GST), the characterization of AWGs is addressed. Three-dimensional domains such as t echnical content, service content, and relationship content are identified. A st rategic path is proposed to guide the organizations how the development of AWGs progresses at different levels of maturity that are associated with organization al effectiveness and performance. The utility of the model for AWGs is expected to provide technology-oriented organizations with a strategic path to achieve h igher organizational performance. 展开更多

Approaches to building renovation require high professional levels, interdisciplinary elements, team work and time to study and do research on the buildings. The process of renovating historic buildings is made up of agreements and compromises between the interests of the government, common interests, and the motives and interests of individual owners and prospective investors. Research that deals with any portion of cultural heritages always carried out very precisely, but there is still no precise knowledge of how to define a system and draw up a model that accurately represents a cultural heritage. In the existing literature on this topic, the authors have written about the different views of how to explain the construction project as a system. While many authors focus on "sub-phases" directly connected to the building of an object, the process involved in the construction phase often neglects the phases required before beginning work, which culminates in a logical sequence in the process of preparing a project. Irregularities or deficiencies which occur during the preparation process of a project often directly impact the construction itself. What the scope of this impact depends on the approach of the contractual organization, the organization of construction companies and on co-operation between the customer (or architects) and the contractors. Unlike the projects for newly built objects, the conservation projects of cultural heritage are not only more demanding because of lack of knowledge of the building materials, construction, foundation and interaction of the mentioned individual parts into a unit called a building. The authors analyzed the structural aspects of building conservation which were suggested by Beckmaun and Bowles and another methodology, which was developed as part of the 5th framework program for the purpose of providing a comprehensive and interdisciplinary treatment of the revitalization of a historical city. The authors found that both methodologies do not include modern IT tools and methods. By analyzing and monitoring the restoration of historic buildings in Slovenia, specifically in the city of Maribor (including all documentation, interviews and direct views) the authors found that the project was regarded as a collection of individual projects rather than a unified whole (a system). The authors have demonstrated the consequences of structuring a historic building restoration project in a non-systemic way. This type of project can be classified as a non-sustainable renovation. In this article, at first the authors will try to clarify what types of systems and subsystems are considered in renovating historic buildings. The authors show when and why a system becomes stochastic (a probability) and in the end what would be needed to successfully re-establish it back to a determined system. By analyzing the work and reconstruction of old buildings in Maribor, the authors found that it would be necessary to give a new framework with IT tools for the preparation of a historic building restoration project. 展开更多

In this paper, the absolute stability of general Lurie type robust control system has been discussed by using the method of Lyapunov function. Some more practical sufficient conditions of absolute stability for the above system are obtained by adjusting the coefficients of Lyapunov functions and parameters of S-procedure. Examples are given to illustrate the method of this paper and the application of new algebraic criteria for absolute stability. 展开更多

The systems sciences and cybernetics emerged in the years after World War II. These fields created many new approaches to engineering and management and contributed new ideas to existing academic fields. The new fields also identified similar concepts across a range of fields and began to create a general theory of systems. In addition the systems sciences created a variety of methods for managing complex systems, for example logistics, operations research and computer simulations. In the 1970s there was concern about population and environment balance. Currently there is increasing concern with governance, since the rate of presentation of problems seems to be greater than the ability of our institutions to manage them. This paper will discuss the history of systems science and cybernetics, the questions formulated and the solutions proposed, the difficulties encountered in Finding a home within contemporary universities and some exciting lines of research now underway. 展开更多
