As a result, management reporting systems (MRSs) began to be developed so that managerial reports and summarized data could be produced.
They are suitable for semistructured and unstructured problems. DSSs often include query languages, statistical analysis capabilities, spreadsheets, and graphics to help decision makers evaluate the decision. DSSs are a type of MIS expressly developed to support the decision-making process. A DSS facilitates a dialogue between the user, who is considering alternative problem solutions, and the system, with its built-in models and accessible database. A typical DSS process involves retrieving a model from the model base and allocating proper data from the database.
Repeating runs with different seed values provides a set of outputs that has a statistical distribution to be analyzed. Many commercial software packages are available that can be used to build simulation models. Some of these are general-purpose simulation languages that have general but powerful features such as waiting lines and resource pools that ease the modeling task. At the other extreme are tailored simulation models (such as oil refinery models) that are already built but afford the user the ability to specify input parameters to describe the precise configuration under study.
