2.5.2 DSS components
At the core of a DSS are a database and a model base. In addition, a typical DSS contains a dialogue manager, which allows decision makers to easily access and manipulate the database and use common business terms and phrases. A DSS also contains presentation tools.
The system is dependent on data which are required to be collected and processed for any decision making. The availability of the data is usually not a problem but the quality is always a concern. The quality concern is very important and the data must go through a validation process before it can be used in the DSS.
The model base in a DSS gives decision makers access to a variety of models to assist them in the decision making process. In supply chain DSS, the models are the mathematical models of the various supply chain activities. These models mathematically represent the supply chain activities and provide decision support based on built in analytical tools. The analytical tools commonly used are heuristics, optimising tools, simulation and AI (artificial intelligence). See your text for more details. The model base may include model management software (MMS) that coordinates the use of models in a DSS.
