CPN simulation model for event log generation

CPN simulation model that can be used to generate event logs with specific process performance characteristics. The generated event log can be used to test and validate process performance analysis techniques.<br>The simulation model represents the sales and delivery process of an electronic goods store. The process involves three business objects for which events are recorded: customer order, replenishment, and shipment. The performance of the process (e.g., waiting times, throughput times, cancellations) are dependent on the configuration of the model. This configuration can be modified by changing the values and functions in the "scenario.sml" file. The required functions for the simulation model are stored in "functions.sml" and the default values are stored in "values.sml". The logging functionality is stored in the "logging.sml" file and contains among others the configuration for the filename and column separator. Events are recorded in CSV format and event attributes include among others the timestamp, the object type and instance, and the performed action.本有色佩特里网（Colored Petri Net，CPN）仿真模型可用于生成具备特定流程性能特征的事件日志，所生成的事件日志可用于测试与验证流程性能分析技术。该仿真模型对应一家电子商品门店的销售与配送流程，流程涵盖三类需记录事件的业务对象：客户订单、补货与发货。流程的各项性能指标（如等待时长、周转时长、订单取消情况等）取决于模型的配置参数，可通过修改"scenario.sml"文件中的参数值与函数逻辑调整该模型配置。仿真模型所需的函数逻辑存储于"functions.sml"文件中，默认参数值则存储于"values.sml"文件。日志记录功能模块存储于"logging.sml"文件中，其中包含文件名与列分隔符等相关配置项。事件以CSV格式记录，事件属性涵盖时间戳、对象类型与实例、执行动作等内容。
