Order-based element labeling for tree-structured XML data is an important technique in XML
processing. It lies at the core of many fundamental XML operations such as containment join …

As software complexity increases, so does the need for precision. For some areas, such as
high-integrity and safety-critical domains, this precision is imperative rather than optional. To …

Context: The demand from industry for more dependable and scalable test-development
mechanisms has fostered the use of formal models to guide the generation of tests. Despite …

Despite being widely known and accepted in industry, the Z formal specification language
has not so far been well supported by automated verification tools, mostly because of the …

In this paper we discuss some issues in implementing a model checker for the Z
specification language. In particular, the language design of Z and its semantics, raises …

Alloy specifications are used to define lightweight models of systems. We present Alchemy,
which compiles Alloy specifications into implementations that execute against persistent …

In this paper we discuss our progress towards building a model-checker for Z. The approach
we take in our Z2SAL project involves implementing a translation from Z into the SAL input …

Previously we proposed a strategy for translating control law diagrams into Circus.
Combining elements from Z, CSP, and a refinement calculus, Circus captures functional and …

对Object-Z 形式规格说明构造测试用例的研究, 目前主要集中在理论研究阶段,
测试用例的自动生成几乎没有相应的工具支持. Object-Z 是基于数学和逻辑的语言 …

A critical step in model-driven engineering (MDE) is the automatic synthesis of a textual
artifact from models. This is a very useful model transformation to generate application code …
