The paper presents the first results of a SNCF and CESIR joint research project whose purpose is to design a constructive and formal method to derive, at each design level, the safety properties of subsystems from the System Preliminary Hazard Analysis. One of the goals of this method is to obtain, at the lowest level, properties of the safety software which can be checked either by formal proof or by testing. The method relies on two concepts: the safety kernel, proposed by J. Rushby (1989), and a generalization and formalization of the notion of \"restrictivity\", used in classical safe hardware design. An application to the Maggaly (Lyon Subway) automatic pilot is presented.","PeriodicalId":319609,"journal":{"name":"Proceedings 1997 High-Assurance Engineering Workshop","volume":"192 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-08-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122007194","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is at present a very expensive activity and one for which there are no generally accepted guidelines. A part of the problem is that failure mechanisms for software are not as readily understood as those for hardware, and that the experience of any one project does not provide enough data to improve the understanding. A more comprehensive attack on the high cost of software test requires pooling of fault and failure data from many projects, and an initiative by NIST that can furnish the basis for the data collection and analysis is described.","PeriodicalId":319609,"journal":{"name":"Proceedings 1997 High-Assurance Engineering Workshop","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-08-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121445325","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The existence of software faults in these systems is not tolerable and a high degree of confidence that safety critical systems meet their reliability requirements must be gained prior to their deployment. The transformational approach to software reliability assessment of process control systems combines the strengths of formal verification and statistical sampling techniques in one unified framework. Partial program proofs are used to amplify the effect of test cases, i.e., they allow us to infer the behavior of the program for many inputs based on its behavior for one input. These transformations reduce the effective size of the input space, typically by eliminating one or more dimensions in the input space. We report on the application of the transformational reliability assessment approach to two control programs in the aerospace engineering domain: a simplified satellite pitch controller and an automatic airplane landing program. Advantages of the transformational approach include significant reduction in size (dimensionality) of input space domain, exact determination of minimal fault size, and reduced sensitivity of reliability estimate to variations in the operational profile.","PeriodicalId":319609,"journal":{"name":"Proceedings 1997 High-Assurance Engineering Workshop","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-08-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132913272","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Central to ReSoFT is a library of reusable software components from which a wide variety of software fault tolerance (SWFT) techniques can be utilized to construct highly dependable systems. The reusable components include: (1) SWFT executive components, (2) SWFT support components, (3) SWFT interface components, (4) fault-tolerant network communication components, and (5) fault-injection components. A set of graphical tools are also provided to build, monitor and test the SWFT systems. The ReSoFT testbed is developed and hosted on a network of Sun workstations running the standard Solaris operating system. The workstations are connected with dual-redundant networks to tolerate communication faults. To ensure effective reuse, object-oriented analysis and design based on the Booch method have been used to develop the reusable components. The components were implemented in Ada 95 to take advantage of its new object-oriented and real-time support features. The graphical tools were implemented in Java which provides object-oriented and platform-independent features.","PeriodicalId":319609,"journal":{"name":"Proceedings 1997 High-Assurance Engineering Workshop","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-08-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129397399","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The approach is based on communicating finite state machines. The formalism allows the encapsulation of communication-related properties in well-defined interface specifications. The encapsulation enables us to use the interface specifications as simple safety kernels and to enforce certain safety and liveness constraints in these kernels, Furthermore, we describe how safety and liveness constraints related to inter-component communication can be formalized using a simple and easy-to-understand constraint language. To formally verify that the constraints are satisfied in an RSML model, we attempt to prove that the constraints are satisfied by only looking at the interface specifications. We illustrate the approach with an example from the TCAS II (Traffic Collision Avoidance System) avionics system.","PeriodicalId":319609,"journal":{"name":"Proceedings 1997 High-Assurance Engineering Workshop","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-08-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129880080","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
