Offering services in the internet requires a dependable operation of the underlying software systems with guaranteed quality of service. The workload of such systems typically significantly varies throughout a day and thus leads to changing resource utilisations. Existing system monitoring tools often use fixed threshold values to determine if a system is in an unexpected state. Especially in low...
Modeling process-oriented enterprise applications asks for combining business process modeling with user interaction and data modeling. Current business process management (BPM) and workflow technologies, however, are neither integrated with user dialogs nor offer an appropriate data model. This paper describes a solution to these shortcomings an integrated framework for modeling process-oriented...
Developing process-oriented enterprise systems not only asks for Business Process Management (BPM) but also for an appropriate user interface and data model. Current BPM and workflow technologies are neither integrated with user dialogs nor offer an appropriate data model. This paper describes a novel integrated framework for modeling process-oriented systems called Processes with User Interfaces...
Simulation systems of thermal power plants now have low using ratio just as operation simulation of generating unit. In this paper OPC technique is used to connect simulation system and distributed control system (DCS) in order to get data shared by different industry systems. In this way the connected system can be utilized for training of engineers, verification test of control strategy, and DCS...
This article presents the main features of a novel construction, symbolic analysis, for automatic source code processing. The method is superior to the known methods, because it uses a semiotic, interpretative approach. Its most important processes and characteristics are considered here. We describe symbolic information retrieval and the process of analysis in which it can be used in order to obtain...
