An Event-Thinking Development Framework for Reusable Model of Parallel and Discrete Event Simulation

Abstract

Parallel and Discrete Event Simulation (PDES) is an important way to dispose problems of analysis simulation for large-scale complex simulation system. How to apace develop reusable model is a key issue to be solved in development of those reusable component model-based PDES applications. However, developing these models usually involves combined knowledge of both very specific domain and PDES, and models built by different domain instead of simulation experts usually have different structures, diversiform interfaces and bind with simulation platforms closely. As a result, they are difficult to be programed efficiently meeting new application requirements while reducing the development costs. To address the problem, this paper first proposed an event-thinking Framework for Developing Reusable component Model of PDES supporting model reuse as well as model calculation parallelization, which contains two parts: (1) four-type basic event structure; (2) object-oriented schedule mechanism. Based on this framework, then our three-phase development approach is elaborated helping domain experts program PDES reusable models fleetly. The case implementation of a naval vessel model indicates that the model using the framework has good reusability and is easy to be developed in PDES applications.
