  1. 1. Formal Specification and Verification of Safety-Critical Software

    Författare :Daniel Larsson; Chalmers University of Technology; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fault injection; fault tolerance; safety-critical; dependability; formal verification; Formal specification;

    Sammanfattning : This thesis is about formal specification and formal verification of software and consists of three different parts. In the first two parts, the formal specification language OCL is treated in two different contexts. The third part describes a technique for analysing the consequences of hardware faults as part of formal software verification. LÄS MER

  2. 2. Synthesis of Safety-Critical Real-Time Systems

    Sammanfattning : A growing number of industrial control applications employ computer control to provide enhanced functionality and reduced cost. Many of these applications are safety-critical and require fault-tolerant techniques to provide an adequate level of safety. LÄS MER

  4. 4. Design of Assured and Efficient Safety-critical Systems

    Författare :Nesredin Mahmud; Cristina Seceleanu; Guillermo Rodriguez-Navas; Joost-Pieter Katoen; Mälardalens högskola; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; embedded systems design; safety critical systems; real time systems; formal method; optimization; model checking; Simulink; Computer Science; datavetenskap;

    Sammanfattning : Safety-critical   systems   need   to   be   analyzed rigorously to remove software/specifications errors, that is, their requirements specifications should be unambiguous, comprehensible and consistent, and the software design should conform to the specifications, hence avoiding undesirable system failures. Currently, there is a lack of effective and scalable methods to specify and analyze requirements, and formally analyze the behavioral models of embedded systems. LÄS MER

  5. 5. Safety Critical Software - Test Coverage vs Remaining Faults

    Författare :Johan Sundell; Kristina Lundqvist; Håkan Forsberg; Emelie Engström; Mälardalens universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; safety-critical software; software testing; Computer Science; datavetenskap;

    Sammanfattning : Safety-critical software systems have traditionally been found in the aerospace-, nuclear- andmedical domains. As technology advances and software complexity increases, such systemscan be found in more and more applications, e.g. self driving cars. LÄS MER
