- Description:
- For about 20 years I have taught System Dynamics modelling at a seminar cource., faculty of commerce, Meiji University , Tokyo. About 6-10 sophomore students used to be divided into 2 groups and each groups and each chose an optimal company or an urban city, for which students tried to formulate a System Dynamics simulation model, and its results were seen every year in a magazine published in Japanese by the faculty of commerce, Meiji University . There were about 30 papers of students, for such companies as super-market, watch, drugs, newspaper, transportation, brewery, bank, gas, restaurant, tobacco, airline and so on, or for a suburban city near Tokyo. Students gathered historical data, had interviews with objective cooperations, formulated models, for which they analysed feedback loops and simulation results. They did all by themselves. These systems thinking studies were of very much value for students. I will explain a few examples from my student’s works and some other Japanese research case studies.

- Description:
- Technology is nowadays considered as an important strategic variable for development. The growth of the developed economies is said to be due to productivity enhancement which is largely attributed to technological innovation. Thus the need emerges for a fuller understanding of the contribution of technology. For improved decision making a new set of technological data will have to be made available and a reorientation of traditional thought will have to be fostered.In the economic production context, technology is simply a means for achieving transformation of available inputs (natural resources and semifinished goods) into desirable outputs (consumer, semifinished and capital goods). To gain a better insight into the role of technology in economic development, it is necessary to view technology as a comprising of four embodied forms (object-embodied physical facilities; person-embodied human abilities; record-embodied documented facts; and institution-embodied management techniques) which interact dynamically at any production system.A framework for measuring the contribution of the four embodiment forms of technology in a production system is presented in this paper. The procedure requires an assessment of the status and interrelationships of the individual components of technology being utilized by a firm vis-a-vis the best practice elsewhere and then to determine the overall “technology contribution coefficient” (TCC) of the transformation operation. The paper suggests the use of the TCC measure for assessing the technological capability of a production system. A careful analysis of the interaction among the four components of technology in relation to the market and policy environment may lead to a better understanding of the technological behaviour of firm with significant policy implications. For such an analysis, the “system dynamics” approach is considered to be suitable because of its ability to deal with complex, interesting and dynamic behaviour of the variables.

- Description:
- The performance of a capitalist system is explained using a system dynamics model of economic growth and income distribution which generates numerous patterns of behavior subsuming both capitalist and Marxist economic views. Extended experimentation with this model then serves as a basis to identify critical policy instruments that make best use if the system potential and avoid dysfunctional developments. Issues of income and wealth distribution and entrepreneurial performances are discussed.

- Description:
- In this paper a system dynamics model of working of a public sector in India is presented and it behaviour has been analysed. The public sector in India are suffering from low productivity, overstaffing and excess capacity. The quality of managerial input, selection process and compensation offered and flexibility in decision making are some of the major causes of under performance. The state owned enterprises have often not to compete with private sectors and the growth in market share is not so emphasized.Apart from this the motivational cycle of the employee working in public sector undertaking is not well pronounced. The socialistic norms of control, which substantially affects the security need over a need pattern of the employee, which is essentially the need pattern closely correlated with free enterprise systems. The situation of conflict arises in case of a state owned company working under a mixed economy systems as obtained in India. This causes low productivity.The paper concludes that each unit should be treated as a separate autonomous body, with flexibility in decision making, better managerial talents have to be attracted. The level of competition should be well pronounced if at all productivity has to be improved. Productivity awareness has to come from the top political circle of the Government and productivity should be treated as national gain.

- Description:
- This paper demonstrates patterns of industrial performance and factors of competitiveness in representative gaming experiment carried out with a help of a simulation model of universal commodity production at Novosibirsk University . The paper inquires about disequilibrium dynamics of the modeling economy and concentrates on repeated decisions of players emphasizing the role of experience and learning in their behaviour. It analyses the intra- and inter- sectoral competition and path-dependent structures of production. The interpretation of experimental results is evoked by Marxian economic theory. The study shows that the applied theoretical framework can lead to propositions deduced or derived empirically in industrial economics.

- Description:
- The identification of the AIDS incubation time distribution, together with its parameters, is a vital component of any mathematical model designed to portray cases. A dataset on Transfusion-Associated AIDS cases in the USA is available and can be utilised in this identification process. However, the task of achieving a best fit using either parametric or non-parametric statistical methods is hampered because, in particular, the data are right-censored and this leads to an extremely complex maximum, likelihood estimation procedure. By employing an appropriate system dynamics software tool an optimising simulation approach to the fitting process is available as an alternative. This enables the resolution of a number of complications which hamper the maximum likelihood approach.

- Description:
- Argentina’s economic growth is seriously threatened by the service of the external debt, when this is compared with Argentina’s payment capacity. The difficulties in the accomplishment of the mentioned payments has caused the decrease of the value of the Argentine debt’s bonds in the secondary markets. This has carried on to the formulation of repurchase strategies of the debt, proposed by Fernandez (1987) and Rodriguez (1988, 1990), which are examined here. For this purpose a simple growth model type Harrod-Domar is coupled to the debt, which grows in function of the unpaid service. Meanwhile, the market price of the debt is governed by a behaviour equation, formulated by Rodriguez ( 1990). A resulting System Dynamics model, which continues a previous work (Rego 1988), permits to simulate alternative scenarios for the economic growth and debt management.

- Description:
- This paper describes two exercises that are useful in an introductory course in system dynamics. They are centered around two models of a couple engaged in a tempestuous relationship. Although the models are quite simple, the exercises can be used to introduce and practice a surprisingly large number of system dynamics skills.

- Description:
- The lack of transportation facilities has been the slackening force to the economic development of most Southeast Asian countries in recent years. A lot of transportation projects has been purposed to alleviate this pressing problem. However, each project is being appraised individually without considering its economic importance with other proposed projects. Economic evaluation is considered on a short term basis neglecting the effects of the project to the whole transportation system on the long term. There is no coordination and systematic implementation to analyze whether a project is important or will be approved first considering the limited funds and resources available. On this research, a system dynamics model is proposed which can analyze the coordination of some projects in terms of economic evaluation.The reliability of this model is tested in Jabotabek, Indonesia which is composed of one urban area and three surrounding areas. The transportation facilities that are considered in this study area are the port which serves as an import-export terminal for products and resources, the trunk roads which provide the link between the urban area and the suburban areas, and other urban transportation facilities located within the urban area.Comparing the trend of the socio-economic growth and development of each expected scenarios is the defined areas, the result shows the importance of coordinating the implementation of transportation facilities.
