IMPLEMENTATION OF A SYSTEM DYNAMICS SIMULATION MODEL: PRICING STRATEGY SIMULATOR IN INTERNET-BASED DECISION SUPPORT
This paper mainly discusses about the Pricing Strategy WebSim, a web-based simulator using system dynamics methodology in decision making process of pricing strategies of voice telephony business. System dynamics methodology is one of the Operation Research (OR) discipline, whereby their conceptual modeling can then be converted into computing models using POWERSIM Studio 2005 software. A mathematical model simulating the growth of subscribers, revenue, traffics, cost and profit of voice telephony business has been made available for use via the Internet. The required input variables are provided by the user and results of multiple simulation runs can be viewed and compared via tables and graphs. The Powersim Software Development Kit (SDK) provides the Application Programmers Interface (API) for bridging the simulation model with the web application. By building a web application for system dynamics simulation model, cost saving is realized by buying a single license and deliver updated versions to multiple users.
