Using formal methods requires adequate tool support. Many formal tools emerge from academic prototypes and evolve towards Industry. This short paper summaries on-going work within the DEPLOY project on providing answers to many practical questions frequently raised by Industry users regarding formal method tools in particular : performance, scalability, integration, user-friendliness, qualification/certification with regards to Industry standards.

After several decades, formal methods are gaining ground in Industry. However, as pointed out by the results of Woodcock et al’s survey, formal methods still need significant additional effort in several areas, most notably in collecting evidence on the use of formal methods and tools in Industry. Such material is crucial for helping companies considering the adaption of formal methods in their decision and deployment process. This talk presents a practical approach for building a repository of evidence material. The main benefits of the proposed approach are first to make it possible to integrate information for many Industry pilots that have tested diverse formal methods. The secondary benefit is that the current implementation of the repository as a wiki of that project is simple yet efficient in managing access but also contribution rights. We highlight different usage scenarios both as passive user, from different roles in the organization, and as contributors, either to point out missing material or as provider of new material.

A non-exhaustive collection of files on NuSMV experiments on the mode synchronization protocol in DSAOCSS. The "input files" are mpbase.smv, split.sh, _split.sh, batch.sh, and inc.txt.The file btc.txt and and all lmp??.txt files have been produced by batch.sh that in turn needs mp??.smv files produced by split.sh.The mp??.smv files are not included in this archive because they are easily reproducible and because every mp??.smv is simply a concatenation of mpbase.smv and a single LTLSPEC line. The file gdbmp22.txt is an output of a debugging session and is included in order to support the conjecture that all segmentation fault messages in btc.txt are due to effective running out of memory in software where use of memory is not properly monitored.

The work of the major EU-funded ICT DEPLOY Integrated Project (February 2008 – April 2012) on Industrial Deployment of Advanced System Engineering Methods for High Productivity and Dependability was driven by the tasks of achieving and evaluating industrial take-up, initially by DEPLOY industrial partners, of DEPLOY methods and tools, together with the necessary further research on methods and tools. Our previous SEN paper introduced the project. The project has been one of the most significant efforts focusing on understanding the issues researchers and engineers face during the deployment of formal methods. This paper briefly reports on the project legacy and provides pointers to the various sources of information produced by the projects.

One of the guarantees that the designers of on-board satellite systems need to provide, so as to ensure their dependability, is that the mode transition scheme is implemented correctly, i.e. that the states of system components are consistent with the global system mode. There is still, however, a lack of scalable approaches to developing and verifying systems with complex mode transitions. This paper presents an approach to formal development of mode-rich systems by refinement in Event-B. We formalise the concepts of modes and mode transitions as well as deriving specification and refinement patterns which support correct-by-construction system development. The proposed approach is validated by a formal development of the Attitude and Orbit Control System (AOCS) undertaken within the ICT DEPLOY project. The experience gained in the course of developing of as complex an industrial-size system as AOCS shows that refinement in Event-B provides the engineers with a scalable formal technique that enables both mode-rich systems development and proof-based verification of their mode consistency.

This Software Requirements Document (SRD) expresses the functional requirements of the Software (SW) of the DEPLOY Work Package 3 (WP3) Distributed System for Attitude and Orbit Control for a Single Spacecraft (DSAOCSS). This system is in many ways similar to the centralized Attitude and Orbit Control System (AOCS) considered by http://deploy-eprints.ecs.soton.ac.uk/266/. However, there are differences up to the extent that the systems should not be assumed to have the same baseline for requirements. The actual Attitude and Orbit Control (AOC) in DSAOCSS is centralized in conventional control-theoretical sense, so the term “distributed AOCS” is too ambiguous to be used in this context.

Each archive contains: (i) an Event-B model of the mode synchronization protocol specified at http://deploy-eprints.ecs.soton.ac.uk/309/ , and (ii) a corresponding ProB Classic model, including files for associated LTL formulas and preferred usage configuration. The Event-B project DSAOCSSv002 is hopefully correct in the case where the system has only two managers and only two modes. The Event-B project DSAOCSSv003 is hopefully correct whenever the system has only two managers and at least two modes.

The Event-B method is a formal approach for modelling systems in safety-, and business-critical, domains. Initially, system specification takes place at a high level of abstraction; detail is added in refinement steps as the development proceeds toward implementation. Our aim has been to develop a novel approach for generating code, for concurrent programs, from Event-B. We formulated the approach so that it integrates well with the existing Event-B methodology and tools. In this paper we introduce a tasking extension for Event-B, with Tasking and Shared Machines. We make use of refinement, decomposition, and the extension, to structure projects for code generation for multitasking implementations. During the modelling phase decomposition is performed; decomposition reduces modelling complexity and makes proof more tractable. The decomposed models are then extended with sufficient information to enable generation of code. A task body describes a task?s behaviour, mainly using imperative, programming-like constructs. Task priority and life-cycle (periodic, triggered, etc.) are also specified, but timing aspects are not modelled formally. We provide tool support in order to validate the practical aspects of the approach.

One important step of the systems engineering process is requirements engineering. Parallel to the development of Topcased, which includes tooling for requirements engineering, a new standard for requirements exchange is emerging at the OMG under the name “ReqIF” (formally called RIF). In our talk we introduce the activities of two research projects and their tool developments, VERDE (Yakindu Requirements) and Deploy (ProR) and discuss possible synergies with Topcased.

Michael Jastram michael@jastram.de Andreas Graf 2011-06-08T16:03:54Z 2011-06-08T16:03:54Z http://deploy-eprints.ecs.soton.ac.uk/id/eprint/307 This item is in the repository with the URL: http://deploy-eprints.ecs.soton.ac.uk/id/eprint/307 2011-06-08T16:03:54Z

Requirements engineering (RE) is a crucial aspect in systems development and is the area of ongoing research and process improvement. However, unlike in modelling, there has been no established standard that activities could converge on. In recent years, the emerging Requirements Interchange Format (RIF/ReqIF) gained more and more visibility in industry, and research projects start to investigate these standards. To avoid redundant efforts in implementing the standard, the VERDE and Deploy projects cooperate to provide a stable common basis for RIF/ReqIF that could be leveraged by other research projects too. In this paper, we present an Eclipse-based extensible implementation of a RIF/ReqIF-based requirements editing platform. In addition, we are concerned with two related aspects of RE that take advantage of the common platform. First, how can the quality of requirements be improved by replacing or complementing natural language requirements with formal approaches such as domain specific languages or models. Second, how can we establish robust traceability that links requirements and model constructs and other artefacts of the development process. We present two approaches to traceability and two approaches to modelling. We believe that our research represents a significant contribution to the existing tooling landscape, as it is the first clean-room implementation of the RIF/ReqIF standard. We believe that it will help reduce gaps in often heterogeneous tool chains and inspire new conceptual work and new tools.

Proper tool support in requirements engineering is important. A number of proprietary solutions are available in the market place, but few open solutions, and none that are widespread at this time. In this paper, we introduce ProR, an open platform for requirements engineering. The project was initiated by the EU FP7 Project ``Deploy'', which has the goal to make major advances in engineering methods for dependable systems through the deployment of formal engineering methods. Rather than building a project-specific solution, we decided to develop an extensible, general purpose platform. We based the tool's data model on the Requirements Interchange Format (RIF / ReqIF), a standard driven by the automotive industry. This gives us interoperability with a number of existing tools. The tool is based on the Eclipse Platform and uses the Eclipse Modeling Framework (EMF). We managed to establish a cooperation with the ITEA-Project ``Verde'', which supplied the implementation of the RIF data model. In this paper, we will introduce the tool, describe its architecture, and present a small case study. ProR is still under development, and we welcome contributors and are very interested in potential users to validate our approach. Please visit www.pror.org for more information, and to download the current development version.

With our growing reliance on computers, the total societal costs of their failures are hard to underestimate. Nowadays computers control critical systems from various domains such as aerospace, automotive, railway, business etc. Obviously, such systems must have a high degree of dependability — a degree of trust that can be justifiably placed on them. Although the currently operating systems do have an acceptable level of dependability, we believe that they development process is still rather immature and ad-hoc. The constantly growing system complexity poses an increasing challenge on the system developers and requires significant improvement on the existing developing practice. To address this problem, we investigated how to establish a set of refinement-based engineering methods that can provide the designers with a systematic methodology for development of complex systems.

The use of business process models has gone far beyond documentation purposes. In the development of business applications, they can play the role of an artifact on which high level properties can be verified and design errors can be revealed in an effort to reduce overhead at later software development and diagnosis stages. This paper demonstrates how formal verification may add value to the specification, design and development of business process models in an industrial setting. The analysis of these models is achieved via an algorithmic translation from the de-facto standard business process modeling language BPMN to Event-B, a widely used formal language supported by the Rodin platform which offers a range of simulation and verification technologies.

Space satellites are examples of complex embedded systems. Dynamic behaviour of such systems is typically described in terms of operational modes that correspond to the different stages of a mission and states of the components. Components are susceptible to various faults that complicate the mode transition scheme. Yet the success of a mission depends on the correct implementation of mode changes. In this paper we propose a formal approach that ensures consistency of mode changes while developing a system architecture by refinement. The approach relies on recursive application of modelling and refinement patterns that enforce correctness while implementing the mode transition scheme. The proposed approach is exemplified by the development of an Attitude and Orbit Control System undertaken within the ICT DEPLOY project.

We examine the the industrial application of formal methods using data gathered in a review of 62 projects taking place over the last 25 years. The review suggests that formal methods are being applied in a wide range of application domains, with increasingly strong tool support. Significant challenges remain in providing usable tools that can be integrated into established development processes; in education and training; in taking formal methods from first use to second use, and in gathering and evidence to support informed selection of methods and tools.

Formal methods use mathematical models for analysis and verification at any part of the program life-cycle. We describe the state of the art in the industrial use of formal methods, concentrating on their increasing use at the earlier stages of specification and design. We do this by reporting on a new survey of industrial use, comparing the situation in 2009 with the most significant surveys carried out over the last 20 years. We describe some of the highlights of our survey by presenting a series of industrial projects, and we draw some observations from these surveys and records of experience. Based on this, we discuss the issues surrounding the industrial adoption of formal methods. Finally, we look to the future and describe the development of a Verified Software Repository, part of the worldwide Verified Software Initiative. We introduce the initial projects being used to populate the repository, and describe the challenges they address.

Distributed information systems are critical to the functioning of many businesses; designing them to be dependable is a challenging but important task. We report our experience in using formal methods to enhance processes and tools for development of business information software based on service-oriented architectures. In our work, which takes place in an industrial setting, we focus on the configuration of middleware, verifying application-level requirements in the presence of faults. In pilot studies provided by SAP, we used the Event-B formalism and the open Rodin tools platform to prove properties of models of business protocols and expose weaknesses of certain middleware configurations with respect to particular protocols. We then extended the approach to use models automatically generated from diagrammatic design tools, opening the possibility of seamless integration with current development environments. Increased automation in the verification process, through domain-specific models and theories, is a goal for future work.

While testing is heavily used and largely automated in software development projects, the reuse of test practices across similar projects in a given domain is seldom systematized and supported by adequate methods and tools. This paper presents a practical approach that emerged from a concrete industrial case in the smart card domain at STMicroelectronics Belgium in order to better address this kind of challenge. The central concept is a test knowledge repository organized as a collection of specific patterns named QPatterns. A systematic process was followed, first to gather, structure and abstract the test practices, then to produce and validate an initial repository, and finally to make it evolve later on Testers can then rely on this repository to produce high quality test plans identifying all the functional and non-functional aspects that have to be addressed, as well as the concrete tests that have to be developed within the context of a new project. A tool support was also developed and integrated in a traceable way into the existing industrial test environment. The approach was validated and is currently under deployment at STMicroelectronics Belgium.

The second DEPLOY annual plenary meeting was held from 21st to 23rd of October in Aix-en-Provence, France. The main difference with respect to the first meeting has been a significant amount of time dedicated to technical presentations of papers. We invited all the academic and industrial partners to submit papers about the work they were carrying on inside the DEPLOY project. The accepted submissions have been then organized in five different sessions, each regarding a DEPLOY relevant topic, plus one for short papers. The structure of this document reflects exactly the structure of the workshop, each of the parts represents a workshop session: 1. Event-B and Extensions 2. Code Generation 3. Event-B Metrics and Tools 4. Model Checking 5. Business Information Systems 6. Short Papers

Recently, Space Systems Finland has undertaken formal Event B development of a part of on-board software for the BepiColombo space mission. As a result, lack of modularization mechanisms in Event B has been identified as a serious obstacle to scalability. One of the main benefit of modularization is that it allows us to decompose system models into components that can be independently developed. It also helps to manage complexity of models that in the industrial setting are usually very large and difficult to comprehend. On the other hand, modularization enables reuse of formally developed components in the formal product line development. In this paper we propose a conservative extension of Event B formalism to support modularization. We demonstrate how our approach can support reuse in the formal development in the space domain.
