This volume contains the proceedings of the 2003 International Conference on Formal Engineering Methods (ICFEM 2003). ICFEM 2003 aimed to bring together researchers and practitioners from - dustry, academia, and government to advance the state of the art in formal engineering methods and to encourage a wider uptake of formal methods in industry.

Invited Talks.- Programs as Paths: An Approach to Timing Constraint Analysis.- Model Based Code Verification.- Adding Formalism to Methods or Where and When Will Industry Use Formal Reasoning?.- Testing and Validation.- Using Formal Methods to Serialize Synchronization Events.- An AMBA-ARM7 Formal Verification Platform.- Formalization, Testing and Execution of a Use Case Diagram.- Service-Based Systems Engineering: Consistent Combination of Services.- State Diagrams.- Using State Diagrams to Describe Concurrent Behaviour.- The Equivalence of Statecharts.- Generic Interacting State Machines and Their Instantiation with Dynamic Features.- PVS/HOL.- Using PVS to Prove Properties of Systems Modelled in a Synchronous Dataflow Language.- Formalising an Integrated Language in PVS.- Refinement.- Modeling SystemC Fixed-Point Arithmetic in HOL.- Adding Action Refinement to Stochastic True Concurrency Models.- Incremental Derivation of Abstraction Relations for Data Refinement.- Comparison of Data and Process Refinement.- Compilation by Refinement for a Practical Assembly Language.- Hybrid Systems.- Java Card Code Generation from B Specifications.- Efficient Path Finding with the Sweep-Line Method Using External Storage.- Formal Development of a Distributed Logging Mechanism Supporting Disconnected Updates.- Formal Proof of a Polychronous Protocol for Loosely Time-Triggered Architectures.- Z/Object-Z.- A Z Based Approach to Verifying Security Protocols.- A Refinement Tool for Z.- The Common Semantic Constructs of XML Family.- Petri Nets.- Controller Synthesis for Object Petri Nets.- Towards a Workflow Model of Real-Time Cooperative Systems.- New Developments in Closed-Form Computation for GSPN Aggregation.- Timed Automata.- On Clock Difference Constraints and Termination in Reachability Analysis of Timed Automata.- Analyzing the Redesign of a Distributed Lift System in UPPAAL.- Verification of Timeliness QoS Properties in Multimedia Systems.- System Modeling and Checking.- A Calculus for Set-Based Program Development.- Compositional Verification of a Switch Fabric from Nortel Networks.- Constraint-Based Model Checking of Data-Independent Systems.- A Formal Model for the Block Device Subsystem of the Linux Kernel.- Semantics and Synthesis.- A Mathematical Framework for Safecharts.- A Relational Model for Formal Object-Oriented Requirement Analysis in UML.- From Specification to Hardware Device: A Synthesis Algorithm.
