摘要： A high fidelity distributed plant simulation technique includes a plurality of separate simulation modules that may be stored and executed separately in different drops or computing devices. The simulation modules communicate directly with one another to perform accurate simulation of a plant, without requiring a centralized coordinator to coordinate the operation of the simulation system. In particular, numerous simulation modules are created, with each simulation module including a model of an associated plant element and these simulation modules are stored in different drops of a computer network to perform distributed simulation of a plant or a portion of a plant. At least some of the simulation modules, when executing, perform mass flow balances taking into account process variables associated with adjacent simulation modules to thereby assure pressure, temperature and flow balancing (i.e., conservation of mass flow) through the entire simulation system. In a dynamic situation, a transient mass storage relay technique is used to account for transient changes in mass flow through any non-storage devices being simulated by the simulation modules. Moreover, adjacent simulation modules located in different drops communicate directly with one another using a background processing task, which simplifies communications between adjacent simulation modules without the need for a central coordinator.

摘要翻译： 高保真分布式工厂模拟技术包括多个单独的模拟模块，可以在不同的液滴或计算装置中单独存储和执行。 仿真模块直接相互通信，对工厂进行精确的仿真，无需集中式协调器来协调仿真系统的运行。 特别地，创建了许多模拟模块，每个模拟模块包括相关植物元件的模型，并且这些模拟模块被存储在计算机网络的不同液滴中，以对植物或植物的一部分进行分布式模拟。 至少一些仿真模块在执行时，考虑到与相邻模拟模块相关联的过程变量来执行质量流量平衡，从而通过整个模拟系统确保压力，温度和流量平衡（即质量流量的保持）。 在动态情况下，使用瞬态大容量存储继电器技术来解释通过仿真模块模拟的任何非存储器件的质量流量的瞬态变化。 此外，位于不同液滴中的相邻模拟模块使用后台处理任务直接相互通信，这简化了相邻模拟模块之间的通信，而无需中央协调器。
