Delsi 2.0 is a discrete-event simulation system designed for simulation of queuing systems with complicated logic. The system is implemented as a set of components for Microsoft .NET 2.0 Framework.

The main idea of Delsi modeling is that your queuing formalization may be presented as an oriented graph with nodes which correspond to some processing facilities (such as generators, queues, servers etc). The arcs of the graph correspond to the streams of processed items. Such items are called transactions.

With Delsi it is possible to control those processing objects and the transaction flow using custom algorithms.

In terms of implementation, Delsi 2.0 is a library (assembly) of simulation components and objects for using in Microsoft .NET Framework 2.0 environment.

During a simulation, transactions are being passed from one block to another. The custom algorithms have to be implemented as event handlers for certain events. The events can be: entering a block, routing, exit from a block, interruption of service and others. By using methods, properties and events of the components, it is possible to control the behavior of a model and obtain necessary statistical results.

Delsi is a general purpose simulation system. It can be applied for the simulation of wide variety of queuing systems in different industries and areas:

Telecommunication
Manufacturing
Computer networks
Call Centers
Transportation
Logistics
Healthcare
Bisiness Processes

Delsi 2.0, in a combination with a standard PC and Microsoft Visual Studio 2005, creates an affordable workplace for developing powerful and rich simulation applications.
