We present a case study where we use automated formal analysis to reason about problem-frame concerns. The descriptions of the problem domains, machine and requirements are written in the Alloy language. We show that an evaluation of results and counterexamples provided by a model finder can reveal useful information that can help remove inconsistencies as well as composition errors.

BACKGROUND Several methods that are currently used for contouring analysis have problems providing reliable and/or meaningful results. In this paper a solution to these problems is proposed in a form of a novel measure, which was developed based on requirements defined for contouring studies. MATERIALS AND METHODS The proposed distance deviation measure can be understood as an extension of th...

Today’s wave soldering processes solder electronic assemblies within the large eutectic tin lead processing window. The issues surrounding the conversion to lead free assembly are multiple and varied. Logistics, cost, material selection, and equipment choices/options are some of these challenges that require planning and organization. However, at the core of lead free assembly is soldering. The...

We introduce a strategy for the verification of relational specifications based on the analysis of monotonicity of variables within formulas. By comparing with the Alloy Analyzer, we show that for a relevant class of problems this technique outperforms analysis of the same problems using SAT-solvers, while consuming a fraction of the memory SAT-solvers require.
