Overview
DESMO-J is anacronym
An acronym is a word or name formed from the initial components of a longer name or phrase. Acronyms are usually formed from the initial letters of words, as in ''NATO'' (''North Atlantic Treaty Organization''), but sometimes use syllables, as ...
for Discrete-Event Simulation Modelling in Java. DESMO-J allows for rapidly and flexibly building discrete event simulation models in Java, supporting both the event-oriented and process-oriented world view. DESMO-J provides a comprehensive set of readily usable Java classes for stochastic distributions, static model components (like queues or resource synchronization), time representation and scheduling, experiment conduction and reporting. Supported by this simulation infrastructure, the user is free to concentrate on specifying the model's behaviour in terms of events or processes.
Development
DESMO-J has been developed at University of Hamburg
The University of Hamburg (german: link=no, Universität Hamburg, also referred to as UHH) is a public research university in Hamburg, Germany. It was founded on 28 March 1919 by combining the previous General Lecture System ('' Allgemeines Vor ...

Modula-2 is a structured, procedural programming language developed between 1977 and 1985/8 by Niklaus Wirth at ETH Zurich. It was created as the language for the operating system and application software of the Lilith personal workstation. It w ...
-based simulation library, which in turn was inspired by DEMOS, a system for discrete event modelling on Simula
Simula is the name of two simulation programming languages, Simula I and Simula 67, developed in the 1960s at the Norwegian Computing Center in Oslo, by Ole-Johan Dahl and Kristen Nygaard. Syntactically, it is an approximate superset of ALGOL 6 ...
