英文摘要： According to the key problems about temporal-aware service process in cloud service environment that emerge in each stage of its lifecycle, in this project we will research the following three aspects: automated dynamic adaptation on modeling stage, real-time monitoring of temporal consistency on execution stage, temporal exception handling and prevention on feedbak analysis stage. Here we explain three researching aspects in detail. (1) We research the automatic construction and correction mechanism of incomplete and inaccurate message mapping, and present the quantitative verification approaches for the various temporal compatibility of process adaptation. Then we study the flexible adaptation of service processes with changeable execution time and service replacement algorithm, as well as interactive adapter customized approach. (2) We study dynamic temporal verification methods under different execution modes, as well as the checkpoint setting strategy. Then the online selection algorithm for services in the execution of processes is researched. (3) In order to guarantee the independence and privacy of the service process, we study flexible exception handling mechanism, and analyze the potential conflict between the business logic and exception handling rules. Then we research exception patterns by process mining, as well as service selection or recommendation approach based on service relation network. Our study is very important for both enhancing the management level of service process for enterprises, and promoting the development of cloud computing software.
