要支持异地软件开发,分布式的过程支持系统的建立是必要的.通过比较4种分布式的过程支持系统的体系结构,引擎分布、数据分布的结构能有效地支持分布式软件过程.设计实现了基于P2P方式的多引擎PSEE(ProcessSensitive Software Engineering Environment)——MEPSS,在MEPSS中,每个引擎具有自治性,同时各引擎间通过交互形成一个完整的过程支持系统. 相似文献

Abstract Software systems are developed by software projects. A software project generally associates with a process (software development process). A software project's process can be managed by process‐centered software engineering environments (PSEEs). In other words, PSEEs facilitate monitoring software projects. When a software project is being executed, many details may be uncertain in the early phases of the project. Therefore, managing uncertainty of a project's process becomes necessary. We identified existing approaches that can manage process uncertainty. Nevertheless, existing approaches suffer from drawbacks such as resource wasting. We thus propose two new approaches, which are pre‐defined semantics and incremental process program development. The former approach prevents duplicating the same code in a process program and the latter handles both predictable and unpredictable process uncertainty. This paper primarily presents the new approaches. 相似文献

Tribo- and photo-stimuated exoelectron emission from reactor graphite has been investigated, because an increase in tribo-stimulated exoelectron emission from graphite signifies large friction. Selective deformation of graphite fibrils was identified with transmission electron microscopy. The exothermic process during the preferred orientation caused emission of tribo-stimulated electrons. Photo-stimulated exoelectron emission from reactor graphite was also detected. However, the mechanisms of photo-stimulated exoelectron emission were different from that of tribo-stimulated exoelectron emission, and photo-stimulated exoelectron emission does not relate to a change in tribological characteristics. 相似文献

基于规则的软件过程事务模型 总被引:2,自引:0,他引:2
事务管理是过程工程环境(PSEE)的一个关键技术.近年来,提出了不少高级事务模型支持长事务.然而,由于软件过程事务处理的特殊性,这些模型只能反映其中一部分需求,而且大多数多层的合作事务模型还不够稳定,无法应用于商业,这对PSEE的事务机制提出了挑战.基于此,提出了一个基于规则的软件过程事务模型E-Process/TM,能够较好地刻画软件过程的特征,即用户交互性、长周期、迭代式过程和数据共享的多用户协作.基于用户可自定义的正确性规则,E-Process/TM提供了良好的灵活性和开放性.目前,该模型已在商业PSEE产品中得以实现,并成功地应用于实践中 相似文献
