- Description:
- The purpose of this paper is to present a model developed for detecting strategic change in efficiency and effectiveness of an industrial company that is structured along with mechanistic concept, produces consumer products, and profit center. Main aim of the research is to develop a model for detecting strategic changes that is a step of strategic issue diagnosis. Which strategic changes are monitored is on dependent on which analysis unit is. In this study it is organizations that are structured with mechanistic concept, vested in a multi product company and profit centre. It can be found in literature that for these companies changes in effectiveness and efficiency are likely strategic changes. Our approach to constructing the model is based on problem detecting approach due to relevant literature. The model consists of two sub model; namely simulation sub model that is a system dynamic model and control chart sub model. The simulation model provides us with distribution of profit values that can be obtained under the normal changes in effectiveness and efficiency. The control chart model receives profit values produced by simulations model and calculates limits to show a manager whether there is a strategic changes in efficiency and effectiveness or not. The model was run by input values of a Turkish company that produces paints. In the test of the simulations model we did not found any statistical difference between profit values obtained from the simulation sub model and one obtained from profit formula, which may be a confidence indicator for validation. As a conclusion it can be said that the detecting strategic changes offers a lot to system dynamic researcher and using management science tools with system dynamic will likely increase strength of it.

- Description:
- Polises are the ancient city-states that began to appear in the Mediterranean around 1000 . They were to be found not only in the area of ancient Greece, but also in Phoenicia and Etruria as well. These polises had different evolutionary paths and relationship with the sea. The aim of the proposed model is to simulate these different paths by introducing cultural factors such as the 'trade aptitude and 'conservative tendency' of the dominant classes and also by considering geographical constraints. The model uses nine main state-variables, four concerning population and five economy. Macro events such as emigration and/or expansion, which may generate new polis, are explained in terms of social conflict between the two dominate classes. The economic unit measure is yearly per capita consumption and the sampling interval is set to one year. The model description also includes a comparison with Forrester's well-known Urban Dynamics. The reasons for the choice of the System Dynamics methodology are expounded in the paper. Two-running examples are discussed and shown as output plots. They deal with a case of high social stability due to sea trade activity of the Emerging class, and also with a case of low stability with generation of new polises. In the authors' opinion, the model offers a general heuristic tool in historical analysis, but may also be useful for approaching present-day problems about the identification of a new development hypothesis for western civilization, in that it recognizes the fundamental role of cultural factors in addition to the economic ones.

- Description:
- The purpose of this paper is two fold. The first is to structure the thinking and theories about managerial learning laboratories as held by the MIT Organizational Learning Center. The second purpose is to go beyond the utilization of management flight simulators and redefine those theories based on the experience of implementing five managerial learning literature is used to frame some of the results from the study and to generate new models aimed at increasing the effectiveness of managerial learning laboratories as group learning setting. The paper can be viewed as iteration of action-research, where active participation of the researcher in the problem situation is followed by reflection and learning from the process. The lessons are then used to update the theories that gave origin to the action.

- Description:
- Today it can be seen that management of change has become a management of 'surprise', in which an enterprise can only survive by recognizing future events in the environment and by acting on that information with appropriate business moves. The ability to learn about these changes requires a kind of organization that never stands still; moreover, enterprises have to develop their own strengths according to their environmental conditions.

- Description:
- The combination of global competition and automation has had a major impact on how contemporary businesses serve their customers. Product development, operations, and sales have all been reshaped by the desire to provide high value products and services to the changing needs of customers. A corporation's ability to compete is intimately tied to its ability to continually develop its workforce. The number of traditional manufacturing jobs in the future will decline; the competency demands will increase. The paper outlines how one company developed six strategies to ensure that the skills of its workforce kept pace with the innovations of its production technology.

- Description:
- Problem Public school systems have server problems that are rooted in the fundamental dynamics of the system. A list of problems include: -Declining performances -Diminished Standards -Relativistic performance assistance -Student motivation -Confused objectives and curicula -Teaching fads -Cultural heterogeneity -non-educational responsibilities of schools -Social pathology -Administrative confusion -Disenchantment with public school Purpose/Objective The objective of the effort was to reduce the public education system to its basic elements: standards, students, teachers and resources; and then to analyze the dynamics of such a system as it responded to three fundamental kinds of disruption: resources waste, teacher diversion, and student distraction. Method/Approach A system dynamics model of a public education system was constructed using STELLA II. It was exercised according to a 5X4 factorial experimental design that examined the behavior of 12 dependent variables under the 20 conditions specified by the factorial design. Findings Results were summarized as a series of parametric plots. For example, plotting Performance X Cost per Performance point gained across all conditions of degradation revealed a significant interaction effect. That is, performance cost at high standards are much less per unit of performance gained, (and much less sensitive to disruption) than those at low standards. Eight major findings are discussed, and a discussion of each of the major identified problems is offered.

- Description:
- Forecasting long-term water demand is essential in water resources planning and management. A common problem existing in long-term forecasting is that many uncertainties are involved due to the various assumptions which can be used. Thus, it is highly desirable to give the assumptions explicitly in a long-term forecasting. By using system dynamics simulations, scenarios can be easily produced based on different assumptions, or by issuing different valued to the parameter and initial variables. And the assumptions can be stated explicitly and organized systematically by presenting the alternatives in tables. The frequency distribution of the forecast results, which are obtained from different scenarios, can be derived. A range of forecasts, rather than a single forecast, can be produced. This can possibly supply an overall picture of a forecast.

- Description:
- The performance evaluation surface relates total cost over a system lifetime to eleven key performance factors. A system dynamic model is developed to project initial cost and trends over the system lifetime. A quadric surface (equation with all linear, quadratic, and two factor interaction term) is fit to a complete factorial design of model runs. These runs span the practical range of factor values. The equation is a generalized cost model that gives a first-cut cost projection for any product or service.

- Description:
- The performance Evaluation Gradient (PEG) model quantitatively compares the relative merits of government operation versus outsourcing to provide government needed goods and services. DOD outsourcing is the contracting out of business-related activities to save money. PEG provides a means to minimize procurement operations and maintenance, and investment costs for a broad range of products and services. Products are categorized by their associated input parameter values. The model evaluates the effect of fourteen key economic parameters on per-unit costs. This section describes the current budgetary environment and the relation of PEG to Functional Economic Analysis (FEA). PEG is applied to a Local Area Network (LAN) services example and summary results are presented.
