We present an algebra with the purpose to efficiently simplify the fault tree structure representing static or dynamic systems, and reduce the repeated events inside. We consider logical unions made up by events as variables. Each variable is represented by an array: 1) it has three elements; 2) each element is a set; 3) the first set contains the Boolean state for this variable; 4) the second set...
Data integration is one of key issues about data exchange and information sharing in distributed computing environment. It is necessary to develop a data structure model which can be used to enhance the data integration for distributed systems. In this paper, we propose a data structure model by which the organization of levels and flexibility of the expression within the systems can be established...
A requirement process plays very important part in software engineering process. In order to truly meet the needs requested by customers, a software engineering system should include a high-quality requirement management process, which can accurately describes the software requirements. In this paper addresses and defines the requirement process to be implemented on a software system. It also reports...
