By definition, the scope of a Bayesian Network uses a complementary technique to restrict the modeling reach. In this paper, the used restriction technique was the goals, questions, and metrics (GQM). The hypothesis to be tested relates cause and effect conditional probabilities in a software test phase of a manufacturing production line. The Bayesian network concept is related to the specific concept...
This paper summarizes a research process applied to final inspection (FI) and causal analysis for problems resolution (CAR) using a real time embedded software component in a production line. It uses C++ language in an IBM-rational rose real time (RRRT) environment. It tackles the creation of a consistent homologation process to eliminate componentspsila errors, imperfections, and defects even before...
This article describes a methodology named Causal Analysis and Resolution (CAR) based on Goals, Questions, and Metrics (GQM) principles. Indicators are defined based on metrics for a decision-making process. Its main contributions are the construction of an information process system model and a prototype, involving GQM approach, in a quantitative definition and qualitative metrics. The CAR methodology...
This paper tackles a logical database integration process implemented for existing databases from the Brazilian National Water Agency (ANA). It describes an important part of a Brazilian Project between ANA and Brazilian Aeronautics Institute of Technology (ITA). The integration process started with a detailed analysis of four existing databases, followed by logical modeling elaboration and integration...
This article proposes an approach for hydrological events monitoring, on a Brazilian national scale. It suggests three working environments for a complex structure where several data categories (hydrological, spatial, inventory, etc.), models (analytical and numerical) and a group of mathematical and statistical analysis tools may be use in an integrated manner. River monitoring in a national scale...
This article describes software reuse components using C language on IBM-Rational Rose Real Time (RRRT) environment. In it a software development process becomes refined by means of a design pattern reuse. Its main contribution meets definition of a process for construction of a Data Logger Platform. Use of design pattern in an Integrated Computer Aided Software Engineering Environment allows definition...
Complex real time systems (RTS) often come with many requirements, which have a difficult description with a large number of scenarios. In order to control this complexity and improve the system QoS, a formal method was applied to decrease the complexity of logical model descriptions, related to state diagrams. The approach introduces a mapping of states diagrams to automata, in order to bring in...
This paper reports an academic experience at the Brazilian Aeronautical Institute of Technology using automated software testing tools applied to a critical real time embedded systems. The work uses a problem-based learning $PBL teaching methodology, a Rational unified process - RUP tailoring, and the IBM-Rational Quality Architect RealTime and the IBM-Rational Test Real Time tools. This academic...
