- Description:
- This paper suggests integrated teaching approaches of System Dynamics methods for socioeconomic analysis, and Geographic Information System for spatial analysis, in examining, evaluating and planning the limits to urban growth and urbanization of city in the course of Urban Planning by taking Bangkok city as a case study. The course if offered for graduate students in the field of Social Sciences at Kasetsart University. Urban Dynamic Model applied in the study includes interactions of population, capital investment of housing, industry and transportation; economic development in terms of gross provincial product and loan interest rates, and land subsystems. The model aims to illustrate problems of shortage and ineffectiveness of City Planning Act which could not control disorderly urbanization and the over supplies of capital investment of housing and industry. Historical patterns of spatial settlements interacting with changes of a socioeconomic behaviour were illustrated. The policy revising the City Planning Act to limit clearly floor area ratio for building construction within the city in relation to land use categories - commercial areas, residential areas, industrial areas - generates the desired urban growth and urbanization.

- Description:
- This paper addressed the survival of an organization in the fight for competitive advantage. A simple model of a non-standard successful organization has been build using System Dynamics which requires definitions of terms such as Quality, Momentum and Inertia. The non-linear nature of this model gives rise to complex behavior which is explored and analysed. It is concluded that for a company to survive in an ever changing environment it is crucial that it the changes as early as possible and responds to them adequately.

- Description:
- Increasing competition in markets, rapid advances in technology and changing organisational styles have contributed to a reduction in product life times and development cycles. The telecommunications industry is becoming very complex with a vast array of products and services, many of which are at least partially substitutable for one another. It is becoming increasingly important to have tools which help companies manage their service portfolio. This paper presents an investigation into product life cycles from perspective of customer choice. A simulation model, based on a system dynamics approach, was developed and the impact on market growth of various influences analysed. Results suggest the model may be used to investigate product life cycles and to evaluate and compare commercial strategies. This modelling activity provides a valuable insight into the potential predictability of product life cycles, the amount a telecommunications service provider may influence a product life cycle and the applicability of system dynamical analyses to an organisations commercial strategy

- Description:
- System dynamic can play an important role in the education of engineers. On the one hand, students in engineering profit from system dynamics. On the other hand, the system dynamics methodology can be enhanced if we take advantage of the training in physics and mathematics received by the students. It is found that new forms of teaching physics (system physics) support system thinking in a unique way. Advanced courses in engineering disciplines can then build upon modeling and simulation taught early on the curriculum.

- Description:
- This paper views three feedback maps of the construction activity in Thailand, development by three experienced modelers as three views of the same problem seen from three vantage points that consider different time frames. The three maps possibly appeared since reference mode for the modeling problem was not explicitly stated, while a wide spectrum of historical data was provided to the modelers. System Dynamics attempts to model processes rather than systems and as such a clear statement of the problem is necessary before a model with a unique structure that corresponds to the stated problem can be formulated.

- Description:
- In line with a previous research (Ryzhenhov 1993), a Goodwin-like model of fluctuating growth is represented by a three-dimensional competitive-co-operative system of non-linear ordinary differential equations. In particular, a labour income share enhances a rate of growth of a capital-output ratio. This ratio, in its turn, adversely affects the rate of growth of employment ratio. Under an appropriate constellation of coefficients and control parameters, this model is capable of generating long waves modelled by converging fluctuations in the vicinity of the dynamic equilibrium (steady-state growth path) or by closed orbits in the phase space. The analytical and experimental results seem to provide a new base for the conclusion that no intrinsic (exogenous) clustering of innovations is necessary to produce long period fluctuations of economic activity as the flow of invention and innovation is contingent upon the rate of capital accumulation. It is shown that the model is consistent with the Kaldor prominent stylised facts and the Valtukh information value hypothesis.

- Description:
- The revolution in telecommunications of the past decade had brought about fundamental changes in the patterns of professional communication. Internet and other electronic networks make it possible for geographically-dispersed individuals to engage in meaningful dialog concerning common problems. These exchanges result in a Global Electronic Community which unique in human experience. This is a community that is truly self-organizing in that it can take on new forms momentarily. Consequently, it is a dynamic community with continually-changing membership and structure; a society populated with both human and electronic agents. It is, as a result, more complex in the roles its members can assume. The sociology of this community is both novel and open to inquiry in depth-in ways never before imagined by students of human society. This paper explores the sociology of the Internet as self-organization system. The Internet is represented as a electronic landscape where users and their agents seek collection of relevant information. The landscape is defined by the accessibility, connectedness and relevance of data files. As users navigate across this landscape, they add both connectedness and relevance. This creates collections of useful information and welds users into Electronic Communities held together by shared models and paradigms. The authors present a System Dynamics model of the prototypic Global Electronic Communitiy. Using the data drawn from Internet file servers, the authors identify the model and show how its structure and behavior conform to the principles of self-organization. Simulation results are used to outline the sociology of such Communities and the implication for professional contributions to sustainable development.

- Description:
- This paper examines a transportation model which is to be used as a support in planning and whose main requirement is general applicability in terms of both geographical area and user levels. The model treats the transport network as a system of finite elements characterized by a transit delay. These elements are nodes, legs or links, and carries. The model consists of a series of cores, each of which applies to a different commodity. Integration in the network takes place on the legs at carrier level. The elements of each core characterized by both operational and economic performance. The dynamics run on two times scales: day-to-day and year-to -year. The model is implemented by discrete-event, object-oriented languages and provides a scenario for decision-making problems, which are typically approached using System Dynamics methods.

- Description:
- This paper seeks to develop an evaluative framework for further consideration of policy design for government and business concerning the problem of serious economic fraud. Considering a resent UK pensions industry scandal and proposals for reform as an example, it is argued that fraud effects the integrity of financial markets and economic well being of society. It draws out of Traditional System Dynamics, Senge's Systems Thinking and Soft System Methodology an approach that link real world problem and systemic thinking in order to produce realistic policy initiative. The paper sets systemic thinking towards just outcomes in the context of legal, economic and political constraints, the eventual aim being to develop acceptable fraud prevention and detection policies at national and business levels. This work is at a preliminary stage and is attempting to take account of both logic based and wider socio legal analysis.
