摘要

服务组合加速了应用程序的快速开发、服务重用和复杂服务的完善，因此，应该评估服务执行吞吐量等定量特征来度量系统性能。基于连续Petri网，建立了服务组合的微分方程模型。利用微分方程解的曲线可以分析其服务行为。该方法的优点是在进行性能分析时避免了状态爆炸问题。我们的方程可以用Matlab求解，并可以用Snoopy工具进行模拟。

Performance Analysis of Service Composition Using Ordinary Differential Equations

Service composition accelerates rapid application development, service reuse, and complex service consummation, thus, quantitative characteristics such as service execution throughput should be evaluated to measure the system performance. Based on Continuous Petri Net, we build differential equation model for service composition. The service behavior can be analyzed from the curves of the solutions of the differential equations. The advantage of our method is that we can avoid state explosion problem while doing performance analysis. Our equations can be solved by Matlab and simulated with a tool: Snoopy.
