- Description:
- With the continuing rise of the complexity of objects, it becomes more and more important and urgent to study the complexity of systems. However we still feel difficult in treating large scale and complex systems in technique because of the high order, multiloop and nonlinerity. In the light of synergetics, a new method of structure analysis is developed. It may have not only the theoretical, but also the practical meanings in the parameter estimations, system optimization, model simplification, dominant loop determination, policy test, etc.

- Description:
- The technology-based products are marked by the severity of learning requirements for the users. Marketing efforts should, therefore, represent not only promotional but detailing activities as well, to overcome the behavioural, technological and related marketing constraints faced by the products. Sales, though a significant factor, does not, by itself, explain the intricacies of the dynamics of marketing. The study tries to explain the nature of interactions amongst behavioural variables that contribute to the successful marketing of technology-based products.

- Description:
- : Classical system dynamics has been presented as a paradigm in its own right. Causal explanations and repeated simulations are the main forte of the method. However, the perceptions on the nature and purpose of the method are so varied that many researchers cannot even place system dynamics in taxonomy of modelling methods. It is difficult to assess the value of system dynamics and justify the choice of such a method. Does the method lack real life significance and suffer from a credibility crisis? The paper looks at the credibility problem from both a philosophical and researcher’s perspective.

- Description:
- Recently the traditional view of “health” as “regularity” has been challenged, and normality is conceived as a sort of constrained randomness and pathology as a loss of the so called spectral reserve. Dynamical diseases would be due to changes in the qualitative dynamics corresponding to bifurcations in the non linear equations describing the system. In this respect, some hematological diseases were modeled in terms of differential-delay equations by assuming a delayed regulation of blood cells production. In the present paper the temporal evolution of the hemoglobin destruction rate of 23 thalassemic children is analyzed. The results indicate that these models are to be partialy revised and that Thalassemia can be conceived as a dynamical disease. A relation between the qualitative dynamics of Hb rate of destruction and the clinical evolution is suggested.

- Description:
- This paper addresses the issue of organizational design and its impact on long term business performance. There is evidence that organizations progress through a series of cycles. We examine the organization design recommendations of Forrester in terms of their impact on delays in a company. We then run a small simulation to explore the impact of these delays on long term company performance. We conclude that most organization structures act to impede long term performance.

- Description:
- An examination of knowledge acquisition techniques and knowledge representation structures used in expert system development and technology forecasting, helped to determine how to elicit information from System Dynamics analysts. In this ongoing research, insights from the literature on knowledge acquisition, combined with knowledge elicited from System Dynamics analysts, are being used to develop an approach designed to improve the knowledge acquisition processes and structures used during the problem formulation and model conceptualization activities of System Dynamics. Also, preliminary insights are presented regarding the selection of knowledge acquisition techniques and knowledge representation structures.

- Description:
- This paper reports results of research on modelling to support management modernization and institutional improvement. It considers middle and long term strategies, and it analyses the effect of successful programs. System Dynamics, an appropriate methodology to support institutional planning, may help to understand system organization, its internal structure and the impact of policies and external perturbations. Strategies analyzed here are based on information systems, management decentralization, and leadership.Simulation results are useful to understand the pertinence of selected strategies.

- Description:
- Negotiation between individuals, groups, and nation has been much in the news lately, and has merited the attention of system dynamic modelers, as was evident at the plenary session on negotiations at the 1990 International System Dynamics Conference. The “Behavioral Simulation Model of Single and Iterative Negotiations” presented there by Darling and Richardson provided a realistic model of critical factors negotiators take into account “while engaged in a joint decision-making process that leads to an outcome” (1990,299). This paper uses their model to explain why “long-term interdependent relationships…[sometimes] drift into increasingly competitive, acrimonious behavior…”(240). Using a fictional piece--“Tell Me a Riddle” by Tillie Olsen--this paper explores “the source of these [competitive] dynamics [which] may be found in the negotiators’ cognitive characteristics --the structure of problems they confront, their situational goals, and their behavioral limits and biases…” (240). After analyzing the behavior of the negotiators-- a couple that has been married for forty- seven years--this paper reframes the power distribution in the relationship and re-writes the script, using cybernetics and syntonoics, a system of interpersonal communication based on “being in tune with one another linguistically”(Elgin, 1987,23). The resulting script saves the wife from becoming a victim of her husband’s verbal abuse, and leads to more satisfactory negotiations.

- Description:
- System dynamics models and executive information systems have complementary strengths in aiding decision making. Information system has vast data retrieval and presentation capabilities. Models provide a dynamic framework for exploring the long-term, systemic implications of decision and polices. This paper reports on an attempt to combine the two approaches-using the model as a lens to structure and view data sets. This paper briefly describes the lens-based executive information system method and explores four tangible benefits of this integrated approach to decision-making.
