This Small Grant for Exploratory Research (SGER) provides funding for the classification of discrete-event simulation models involving complex entity interaction and the development of several sample models using commercial simulation packages. Complex interactions are those in which the flow of the entities and the behavior of the resources are highly dependent on the system state. Simulation models of these systems are characterized by having numerous "user-defined" wait states for entities. In these models, resources can not be simply passive capacity maintenance mechanisms, but rather they must implement specific allocation logic. There are a surprising number of seemingly straightforward models that belong to this class. This class of systems will be characterized and documented and modeling methodologies for problems is this class will be developed. In addition, a test suite of problems will be developed and models for these problems will be developed using several commercially available simulation software packages. These models will be compared with each other and with hand-coded event-oriented models of the same systems.If successful, the results of this research will provide methodologies for developing discrete-event simulation models of a class of systems involving complex entity interactions along with a suite of example models implemented in several commercially available simulation packages. The long-term goal of this research is to develop an open-source simulation toolkit to specifically support the development of models for complex systems. The result will be a freely available simulation software package along with significant educational materials. Note that the goal of the toolkit is not to compete with the commercial simulation packages, but, rather, to supplement them and to provide tools to support the teaching and understanding of general simulation principles. Actually, improving the understanding of general simulation principles will benefit the commercial packages by increasing the probability of success for simulation projects.

这一探索性研究小额赠款(SGER)为涉及复杂实体相互作用的离散事件模拟模型的分类和使用商业模拟包开发几个样本模型提供资金。复杂交互是指实体的流动和资源的行为高度依赖于系统状态的交互。这些系统的仿真模型的特点是具有许多实体的“用户定义的”等待状态。在这些模型中，资源不能简单地作为被动的容量维护机制，而是必须实现特定的分配逻辑。有数量惊人的看似简单的模型属于这一类。这一类的系统将被描述和记录，并将开发针对问题的建模方法。此外，将开发一套问题测试，并将使用几个商业可用的模拟软件包开发这些问题的模型。这些模型将相互比较，并与相同系统的手工编码的面向事件的模型进行比较。如果成功，本研究的结果将提供开发一类涉及复杂实体相互作用的系统的离散事件仿真模型的方法，以及在几个商用仿真软件中实现的一套示例模型。这项研究的长期目标是开发一个开源的仿真工具包，专门支持复杂系统的模型开发。其结果将是一个免费提供的模拟软件包以及重要的教育材料。请注意，该工具包的目标不是与商业模拟包竞争，而是对它们进行补充，并提供工具来支持一般模拟原理的教学和理解。实际上，提高对一般仿真原理的理解将增加仿真项目的成功概率，从而使商业包受益。
