Abstract

Procedural modeling languages utilize transactions as their only active entity. These transactions can flow through a network simulating the logical and physical properties of a real world system. It is natural for the transactions to represent units of demand using a set of resources. However resources, especially within social systems, are not passive and play an active role in choosing transactions to service. To model those environments in a transaction-oriented language requires the simultaneous treatment of resources and demands as transactions and compels the modeler to explicitly consider their interface and synchronization. In INS the modeling of combined active transactions-active resources is facilitated by the introduction of a second active entity, namely resources whose role is different than but easily coordinated with transactions. The INS resource allocation processor permits the high level manipulation of these dual entities allowing the modeler to represent very complex systems easily.
