Introduction to JSIM

In JSIM, simulation models may be built using either the event package (Event-Scheduling Paradigm) or the process package (Process-Interaction Paradigm). In addition, a graphical designer (jmodel package) allows process models to be be rapidly built graphically. The qds package (Query Driven Simulation) under development controls the storage, retrieval and execution of simulation models as Java Beans and utilizes JDBC to access databases. It also stores model inputs and outputs. Finally, JSIM has three foundation packages: queue, statistic and variate.

JSIM evolved for earlier work on simulation environments. This work involved the development of algorithms for model instantiation, specification of criteria for the adequacy of query responses, and design and implementation of prototypes of a Query Driven Simulation (QDS) system/environment which transparently integrate database management with model management. One prototype using the SIMODULA simulation language was built on top of an extended relational database system, OBJECTR , and a second prototype was built on top of an object-oriented database system, Active KDL ).
