This research is aimed at presenting a meta-model that will be used as a basic structure of modeling an on-line selling distribution system. In an electronic commerce (EC) business system, demand, operating conditions and environment are random and unpredictable. An EC business system also involves several sub-systems, such as:information, manufacturing, communication, and management. In addition to this, the entire system is based on a static distribution system and operated in a dynamic environment. Therefore, a reliable mathematic model is not to be available.
Instead of modeling this system in a direct way, we can separate the modeling into two levels. Within the first level, we will define and model the static distribution system. At the second level, we will define and model the dynamic characteristics and behaviors. Then we can combine these two together as a meta-model for the decision makers. Decision makers can use this meta-model as a basic structure for systems such as this.
