A software-based integration of agent-based modeling and system dynamics is presented. More precisely, it is described how RePast and Vensim can be coupled using standard procedure calls. In an example from supply chain management, agents modeled with RePast in an agent-based simulation context are provided with system dynamics models as internal schemata, which are built with Vensim. The proto...

The heterogeneous networks belonging to different service providers (SPs) form a coalition system for maximizing the profit, where they may either compete or cooperate with each other. In this paper, we introduce Lokta-Volterra model, a differntial dynamics model, to build the competitive and cooperative mechanisms of heterogeneous networks. It considers the natural growth rate of the network i...

Using System Dynamics method, this study analyzes the SMS governance. A System Dynamics Model is built and is simulated with VENSIM PLE 5.4C. The simulation result proves that carries should be the key entity to be governed. This study also uses the model to analyze SMS policies and finally gets the conclusion that real mobile identification and unification the service providers’ access number ...

This appendix describes a variety of software programs for system dynamics modeling. It begins with spreadsheet programs since these are probably the most widely recognized software. The appendix demonstrates that spreadsheets can be constructed to simulate behavior over time. But this is not their best use; spreadsheets are better used to support dynamic modeling in programs like Stella or Ven...

Logistics runs through the entire process of an enterprise’s production and management. Logistics, as an enterprise’s "the third profit source", is an effective management tools for companies to obtain and maintain a competitive advantage, the management of logistics risk of marketing channels is a critical part of the risk management of channels. The paper introduces the logistics risk types, ...

The thesis analyzes the development problem of private cars’ amount in Beijing from the perspective of system dynamics. With the flow chart illustrating the relationships of relevant elements, the SD model is established by VENSIM to simulate the growth trend of private autos’ amount in the future on the background of “Public Transportation First” policy based on the original data in Beijing. T...

In this article, a new method is presented to research the mechanism of Customer Satisfaction (CS). Firstly, the research model of CS based on the TAM and ACSI is built. Secondly, some important correlation coefficients of research model can be got from the SEM method. Thirdly, with these correlation coefficients, the main functions of system dynamic model are built, and the evolution of the sy...
