  • In the recent Internet environment, there are different competition patterns among competitors as it was before. As we see real world example such as Covisint in automobile industry and Exostar in aerospace industry, collaboration among competitors now takes place and industry-wide B2B marketplaces come into existence. Hence, we suggest the extended system dynamics simulation model based on Kim(2002)’s collaboration profit models in order to explain competitors’ collaboration in the e-business environment. After all, we investigate the necessity of collaboration between competitors, and show the presence of the optimal investment decision making to collaborate. We also show that the effect of collaboration is changed as varying the industry characteristics such as standardization and volatility.

  • IT companies make a lot of efforts for sharing and utilizing of experiences of their members and transforming them into the organizational knowledge as a competitive core. But they face a dilemma that they have to spend time and financial resource to perform activities around knowledge management for the long-term gains, while carrying field-works for making short-term profits. As an initial attempt to tackle this managerial problem, this paper try to investigate the mechanism of knowledge management in a small IT company in Korea with a synthetic view-point using system dynamics simulation model. It depicts the dynamic behaviors of knowledge management and presents some findings of political leverage. Although it has to be replenished further, the scheme for the dynamism of knowledge management and the findings presented in the paper could be useful for the decision makers particularly of knowledge-intensive organizations

  • This paper is the result of simulation modeling concerning high-level radioactive waste repository(HLRWR) and people's mind for the facility. We describe a procedure of simulation modeling for resident's policy acceptance and perceived risk of HLRWR facility by using System Dynamics approach. To Complete some complicated works, we made the 20 pieces of stock-flow diagrams based on the causal loop diagram that is a blue print of whole variables and relations. The simulation outputs clearly show that cental government efforts to siting the HLRWR will be failed if nothing to give for the region's residents. On the contrary, a monetary incentive and a regional development program help to turn this gloomy situation into a desirable and acceptable condition dramatically. Government has to prepare the schemes considering the HLRWR acceptance and total supporting program including the cash and local development programs.

  • During the past few years, cyberspace and electronic commerce has been expanding throughout the world rapidly. The purpose of this paper is to find out policy leverages for boosting up cyberspace and electronic commerce using system dynamics simulation modeling approach. The system dynamics simulation model developed in this paper allows analysis of both the effect of factors on dynamic growth pattern of cyberspace as well as the effect of time delay in information processing, money transfer and delivery on model behavior. Finding of this study is that capacity of information infrastructure and size of cyberspace population are key factors of cyberspace growth. Also, reducing time delay in information flow, money flow, and delivery flow is an important policy leverages for growth of electronic commerce.

  • This study has tried to suggest a new model that can effectively redistribute the tickets in the online ticket resale market, while suggesting a new allocation mechanism based on an agent negotiation. To this end, this study has analyzed and simulated the secondary ticket market through System dynamics. As a result of these simulations, it has been proved that the price stability of ticket resale market leads to an increase in revenue. An agent negotiation helps to stabilize the ticket prices that are usually inclined to rise at auction, benefiting all the participants in the negotiations, consequently showing a Pareto solution.

  • This paper on an experiment, using System Dynamics, on the affect of increase in number of beds and medical instruments used for the care of premature infants, which constitute the physical requirements in quality of medical services, on changes in the survival rate of premature in ants that leads to demographic changes of Newborn infants. The model has four sectors: take-in capacity, survival rate of premature infants, demographics without newborn infants and demographics with newborn infants. The model simulates the changes in demographics of the newborn infants from 2002 to 2022. The study results show that the survival rate of premature infants can be increased by improving the physical aspects in the quality of medical services. An average of 1,900 premature infants can survive as a result of the physical quality improvements in medical services, adding up to an increase of 37,300 newborn infants by the year 2022.

  • This study has been performed to consider how to support to be effectively linked hiring of skilled human resources that were discharged through actually related education programs, as demand of they are recently being increased due to the expansion of the logistics market, and effort to train them is being propelled. That is associated with the Busan region, and field of logistics service is 3PL that is seriously considered the area of professional services at the last logistics market. Through the methodology of System dynamics, this study has been modeled about dynamic mechanism considered the growth of logistics marker and relation to employment, and has been estimated about ripple effect within logistics market of major policies related with them.

  • This research consists of (1) building (or molding) the Dynamics Simulation Model on Return Policy mainly used in publications, phonographs, and computer industry; which are seen used in supply chain contract known as effective control mechanism under the varied supply chain situations, and (2) analyzing the effects that return rates and seller's contract parameters have in the outcome of the model and (3) observing how the effectiveness of Return Policy changes under such circumstances where the buyer's sales ability and the seller's risk inclination are taken into account. Thus, the main purpose of this research lies in analyzing what exactly are the effects (and or outcome) that sales ability and risk inclination have in Return Policy, and additionally by conducting comprehensive research on Supply Chain Policy Dynamics Simulation Model, we will try to prove that not only the Systems Dynamics approach is highly contributive in supply chain management but also that it will serve as a foothold in future research. As a result of the research, supply chain achievement level turned out to be high when Return Policy is enforced, and the achievement level was even higher when seller's sales ability was taken into consideration along with the Return Policy. On the other hand, the achievement level decreased when the seller had risk aversive tendencies.

  • This study suggests a set of Causal Loop Diagram (CLD) of Causality Mechanism which integrates the matter of characteristics of emerging market and its expansion strategies. In order to make CLD more objective, all causalities are articulated from recent 55 studies (2000~2012) of SSCI Top Journals. This approach is valuable in that it is a first try to draw all the causalities from rigorous literature review regarding emerging market strategy. The 5 CLDs will show and clarify the strategies of how to expand into emerging market for MNCs. In sum, political activity and institutional void is a critical factor related to characteristics of emerging market, and CSV and cultural distance should be considered as a leverage point. For all this study's contribution to clarify the causality of emerging market strategies with abundant literature review, the study has its limits in integrating and testing CLD.

But, most research have been lacking in covering the overall aspects of the causes which IMF stand-by arrangement results from. This paper extracts the reasons of IMF stand-by arrangement using Mind Mapping methods and intends to draw up cause & effect map.
