An approach to software reliability prediction and quality control

December 5-7, 1972, Fall Joint Computer ConferenceThe increase in importance of software in command and control and other complex systems has not been accompanied by commensurate progress in the develop- ment of analytical techniques for the measurement of software quality and the prediction of software reliability. This paper presents a rationale for imple- menting software reliability programs; defines software reliability; and describes some of the problems of performing software reliability analysis. A software reliability program is outlined and a methodology for reliability prediction and quality control is presented. The results of initial efforts to develop a software reliability methodology at the Naval Electronics Laboratory Center are reported

On the engineering of crucial software

The various aspects of the conventional software development cycle are examined. This cycle was the basis of the augmented approach contained in the original grant proposal. This cycle was found inadequate for crucial software development, and the justification for this opinion is presented. Several possible enhancements to the conventional software cycle are discussed. Software fault tolerance, a possible enhancement of major importance, is discussed separately. Formal verification using mathematical proof is considered. Automatic programming is a radical alternative to the conventional cycle and is discussed. Recommendations for a comprehensive approach are presented, and various experiments which could be conducted in AIRLAB are described

Theory of reliable systems

The analysis and design of reliable systems are discussed. The attributes of system reliability studied are fault tolerance, diagnosability, and reconfigurability. Objectives of the study include: to determine properties of system structure that are conducive to a particular attribute; to determine methods for obtaining reliable realizations of a given system; and to determine how properties of system behavior relate to the complexity of fault tolerant realizations. A list of 34 references is included

Static Value Analysis over C Programs

Analýza rozsahu hodnot (anglicky value-range analysis) je metoda statické analýzy založená na zjišťování hodnot, kterých může daná proměnná nabývat v určitém místě v programu. Tato technika může být použita k dokázání, že se v programu nevyskytují chyby za běhu, jako například přístup za hranici pole. Jelikož analýza rozsahu hodnot získává informace o každém místě v programu, lze k její implementaci využít analýzu toku dat (anglicky data-flow analysis). Cílem této diplomové práce je návrh a implementace funkčního nástroje provádějícího analýzu rozsahu hodnot. Práce začíná úvodem do problematiky, vysvětlením analýz toku dat a hodnot proměnných a popisem abstraktní interpretace, která tvoří formální základ analyzátoru. Následuje seznámení s prostředím Code Listener, které bylo využito k implementaci analyzátoru. Jádro práce tvoří návrh, implementace a otestování analyzátoru. V závěru jsou shrnuty nabyté zkušenosti a diskutovány možnosti budoucího vývoje vytvořeného nástroje.Value-range analysis is a static analysis technique based on arguing about the values that a variable may take on a given program point. It can be used to prove absence of run-time errors such as out-of-bound array accesses. Since value-range analysis collects information on each program point, data-flow analysis can be used in association with it. The main goal of this work is designing and implementing such a value-range analysis tool. The work begins with an introduction into the topic, an explanation of data-flow and value-range analyses and a description of abstract interpretation, which provides the formal basis of the analyser. The core of this work is the design, implementation, testing and evaluation of the analyser. In the conclusion, our personal experience obtained in the area of the thesis is mentioned, along with a discussion of a possible future development of the designed tool.
