- Description:
- The issue of performance measurement is getting more critical to the public-sector organizations as well as the private domain as environmental changes become more dynamic and complex. Recognizing the importance of intangible assets, the public organizations have started to introduce Balanced Scorecard as a means of managing and measuring their performance. Unfortunately, however, BSC, a wisdom of the private sectors, is not properly workable unless it is modified by reflecting the unique characteristics of the public organization. In addition, the traditional BSC fails to accommodate into its model the dynamic structure within which indicators are interrelated and interacting with time delays. Therefore this paper aims to devise a dynamic-BSC model appropriate for the public organizations by introducing the system dynamics concept with a focus on the effect of casual relations and the interactions among the key indicators and taking into account the impact of delayed feedback caused by new policy and legislative changes.

- Description:
- The study of Dynamic Decision Making (DDM) has contributed to our understanding of the behavior of decision makers in the dynamic decision making environment. This article attempts to apply the findings of the previous DDM research to the monetary decision making at the Federal Reserve Board. The monetary policy is a typical example of the DDM. By analyzing the Federal Open Market Committee (FOMC) meeting transcripts, the decision making environment and behavior of the FOMC will be identified. The FOMC members face unfavorable decision making environment that corresponds with the DDM findings, but it is also revealed that they were able to develop ways to overcome the difficulties. This article also suggests possibilities of future DDM study and application of DDM prescriptions to the FOMC decision making.

- Description:
- Dryland salinity is an insidious problem which progressively degrades arable or marginally productive farming land often to the point that such land becomes incapable of sustaining agriculture in the long term. In Australia, this problem has been exacerbated by the removal of millions of trees to make way for cultivation. This paper explains how founding research focusing on identification of reference modes of behaviour for dry land salinity has been used to define the requirements for a system dynamics model designed for strategic analysis and to inform choices for strategic management of dryland salinity in Australias Murray-Darling basin. The system dynamics model constructed on the basis of the previously identified reference modes is described. Its behaviour is analysed and its veracity as an explanation of the causes of dryland salinity, and possible remediation of this widespread and worsening problem, are critically examined.

- Description:
- T.P. Wright (1936) described the learning curve theory, that repetition of the same operation results in less time or effort expended on that operation. While many studies have examined the learning curve under various situations such as manufacturing (e.g., Argote and Epple, 1990) and customer service (Dart, Argote, and Epple, 1995), surprisingly little attention has been given to companies for whom learning is an imperative for immediate survival those companies with very few accumulated resources and therefore little time to learn before organizational collapse. Leslie and Holloways (2005) Enterprise Sales Learning Curve attends to early-stage companies by addressing factors within the organizational learning system, but with a rather static approach to the inherently dynamic learning phenomenon. This paper animates Leslie and Holloways framework and addresses the key question: How do early stage companies allocate their scarce resources to accelerate the progress of their sales learning curve?

- Description:
- Some kind of dual problem of optimization, on the base of simulation on the model type System Dynamics, is presented. Authors refere to question of, so called, optimization embedded in simulation. Some new results of experiments with the comparison of the solution of the minimization of cost and maximization of profit in the firm are described. The generalization of formulation both problems in matrix form, on the example of described model type System Dynamics is proposed.

- Description:
- The problem of sensitivity analysis of parameters and structures in System Dynamics models is rather new for field modelers. The possibilities of packet COSMIC and COSMOS allows to apply extended sensitivity analysis not only of parameters of the simulation models but structures of these models too.

- Description:
- Since the introduction of systems thinking inventory tasks or Bathtub Dynamics tasks in 2000, an increasing number of researchers and educators have confronted various student groups and post-graduates with these tests to assess and evaluate their understanding of basic system thinking skills and system concepts. Surprisingly, the results showed a poor performance. This motivated us to subjecting students in Germany to the Bathtub Dynamics tests so as to broaden the international research data and to gain a better understanding of the current level of system thinking skills in selected student groups at our educational institutions. Three different groups, two at university and one at high school level, received the same tasks. The performance results were compared to each other and to other research studies that applied the same tests. The task results were assessed to discover any correlation with the subjects demographics, such as age, gender, previous degrees or university courses. As was shown with other studies, the overall performance was poor given the participants education level. The interesting aspects are the specific differences in performance between and within the individual groups and the relationship to demographic factor such as gender.

- Description:
- In this study, a simulation model is built to study the body water regulation and its disorders by focusing on the fundamental feedback mechanisms in the normal and disease physiology. This model is then extended to include related therapeutic interventions of the most common body fluid/electrolyte disorder, namely water intoxication/ hyponatremia, and a game version is produced to test the possible effects of a given set of treatment options on a simulated patient. The model is shown to adequately reproduce the changes in the body fluid balance not only in a normal person as a result of a given disturbance, but also in a hypothetical hyponatremia patient. The interactive simulation game version of the model proves to be a useful experimental platform to describe changes known to occur after administration of various pharmacological means. The aim of the treatment is to increase the extracellular sodium concentration safely by reducing the body water and replenishing the sodium deficits. Game results demonstrate that hypertonic saline should be given carefully concurrently with drugs that increase urine flow, and antidiuretic hormone-antagonists happened to be superior over diuretics. The model and the game version constitute an experimental laboratory for a closed-loop therapy approach to hyponatremia.

- Description:
- This paper proposes a combined research approach of simulation and modeling and qualitative empirical social research. Modeling and simulating may reveal valuable insight into real world systems consisting of a complex structure. Yet, published data on structures, like learning alliances, are oftentimes limited and stand side-by-side, without interrelation. Qualitative empirical social research might provide model builders with appropriate missing data. Though applying real-world data has long tradition in System Dynamcis, a comprehensive scientific explanation is still omitted. In this paper we view modeling from an outsider perspective, like, i.e., an alliance scholar who needs to be convinced about the benefits of simulation and modeling. Model quality and model acceptance, among other things, depend on realistic model input, including non-rationality or real-world policies. We analyze how qualitative empirical social research may ensure that the model builder works with real-world input that she might use for building the simulation model and for her analysis.

- Description:
- South Africas Motor Industry Development Programme (MIDP) adopted in 1995 was hailed as a successful and innovative industry policy by all stakeholders. Despite attracting significant investment by almost all major global vehicle manufacturers, consensuses is declining that the programme can successfully steer the industry to sustainable future growth. The paper presents findings of an investigation into the declining consensus on the MIDP. A review of the MIDP mental model is done. Industry performance data from 1995 to 2004 is evaluated against programme objectives. Findings show that the declining consensus is due to failure to acknowledge interrelationships among industry variables. The programme success has not been across board and policy makers have paid little attention to synergies between industry sectors. The MIDP presents a classical case of a system dynamics problem that can benefit from system dynamics modeling.
