Most model constructs in organization studies are descriptive in nature, and the conclusions relating to the model behavior over time are speculative. The usefulness of System Dynamics as a methodology for modeling and testing dynamic behavioral hypotheses in organizational behavioral studies is presented, and how to construct a System Dynamics model using simulation software(VENSIM) is shown, The well-know March and Simon motivation model is used to demonstrate the step by step application of System Dynamics to model of this type. The dynamic behavior of the model, both transient and steady state, is obtained, Even though the paper has focused on one model in the area of individual behavior, the approach is general and can be applied to other areas of organizational behavior as will. The usefulness of System Dynamics as a methodology for theory building is identified as well.

In this paper, we proposed a modeling method of continuous combat simulation by using VENSIM. VENSIM is a CASE tool for developing continuous simulation. It provides a simple and flexible way of building simulation models from causal loop or influence diagram. As a case model, we developed "a prototype model of battle"incorporating infantry, artillery, air defense weapon, aircraft, and guerrilla engagement.ngagement.

A social network is a typical social science environment with both network and iteration characteristics. This research presents a reaction analysis model of how each node responds to social networks when given input such as promotions or incentives. In addition, the setting value of a specific node is changed while examining the response of each node. And we try to understand the reactions of the nodes involved. The reaction analysis model is constructed by applying various techniques such as unidirectional, fuzzy set, weighting, and cyclic feedback, so it can accommodate the complicated environment of practice. Finally, the implementation model is implemented using Vensim rather than NetLogo because it requires repetitive input, change of setting value in real time, and analysis of association between nodes.

This paper describes not only the complexities of LNG business including shipping sector but also its own current environmental changes. Furthermore, system dynamics (VENSIM analysis) as a methodology is introduced to analyze the potential LNG shipping market in the future. As a result of the VENSIM analysis, potentiality of the spot LNG shipping market is systematically established in connection with embodiment of the spot LNG market. This paper suggests three methods, which are centered on newbuildings of ships, for the shippers to prepare for the spot LNG shipping market on the basis that maritime economics can make a direct contribution to the shippers' business decision-making.

2004년7월1일부터 시행이 시작되어 현재 1곳의 시범지역을 운영하고 있는 구역전기사업은 소형열 병합발전을 기반 기술로 활용하고 있다. 국내 구역전기 사업의 잠재량 예측을 위해 본 연구에서는 인구증가율과 인구증가율에 따른 주택건축수요를 기된 데이터로 사용하였다. 잠재량예측을 위해 프로세스는 시스템다이나 믹스 모델인 VENSIM을 사용하였다. VENSIM에서 예측된 주택수요에 따라 택지 잠재량을 계산하였으며 계산된 택지 잠재량 중 구역전기사업을 수행했을 때 사업자입장에서 사업성 판단 기준에 따라 구역전기사업의 잠재량을 예측하였다.

Ptak & Smith published ORLICKY'S Material Requirement Planning Third Edition in 2011 to correspond the rapidly changed market demand by improving the original MRP based on Theory of Constraints(TOC) replenishment inventory management. This study is to develop the simulation model to decide the proper target inventory level for TOC replenishment inventory management using system dynamics Vensim software. This study shows that the proper target replenishment level is how much significant to manage the inventory by the random sample data simulation. This simulation model will be extended to compare the results of the TOC replenishment inventory management planning with the results of the old MRP planning by the enterprise actual inventory data.

The usage of Social Network in business environment is now processing various methods. The purpose of this paper is doing a simulation about how each node of social network reacts to a special input, and how a specific node have an effect to other nodes. Also, when we change weight of node in the same input, we can trace about change of node status in real time. So, we can use this model for identification of important person in social network, and we can use it for checking the reaction of person in specific input. we use VENSIM program for modeling and simulation process.
