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.

这项用于探索性研究的小赠款（SGER）为涉及复杂实体相互作用的离散事件模拟模型的分类提供了资金，并使用商业仿真软件包开发了几种示例模型。 复杂的相互作用是实体流的流动和资源行为高度依赖于系统状态的相互作用。 这些系统的仿真模型的特征是具有大量的实体等待状态。 在这些模型中，资源不能仅仅是被动能力维护机制，而是必须实施特定的分配逻辑。 属于此类的模型有很多令人惊讶的模型。 这类系统将被表征和记录，问题的建模方法是将开发此类。 此外，将开发一系列问题，并使用多个可商购的仿真软件包开发这些问题的模型。 这些模型将彼此进行比较，并与同一系统的手工编码的面向事件的模型进行比较。如果成功的结果，这项研究的结果将为开发涉及复杂实体交互的系统的离散事实模拟模型以及在几个市值可用的仿真包中实现的示例模型的套件。 这项研究的长期目标是开发开源模拟工具包，以专门支持复杂系统模型的开发。 结果将是一个免费的仿真软件包以及重要的教育材料。 请注意，该工具包的目的不是与商业模拟软件包竞争，而是要补充它们并提供工具来支持对通用模拟原则的教学和理解。 实际上，提高对一般仿真原则的理解将通过增加模拟项目成功的可能性而受益。
