运维过程复杂度建模及有效性验证

建立了基于复杂性理论的信息系统运维过程复杂度模型，定义了执行复杂度、参数复杂度、上下文复杂度、交互复杂度和并行复杂度5个指标，给出了指标的形式化定义和计算方法，并且提出了使用归一化函数对指标数据进行处理，以比较单一指标在整体复杂度中所占比重的方法，最后通过开设1个电子邮件服务系统的实验验证了模型的有效性. 该模型可用于度量信息系统运行维护过程的复杂程度，寻找运维热点，进而可以评估和优化运维过程，以提高运维质量和效率.

Operation Process Complexity Modeling and Validation Verification

An information system operation process complexity model based on complexity theory is proposed. Five metrics included operation complexity, parameter complexity, context complexity, interaction complexity, and parallel complexity are defined, The formal definition and calculation method of metrics are presented. Furthermore, the normalization function is proposed, it can process metrical data and compare the single metric influence in total complexity. The model validation is verified by constructing an E mail service system. This model can be not only used to measure the complexity degree of information system operation process and search operation hot spot, but also to evaluate and optimize the operation process in order to improve the operation quality and efficiency.
