%A Marta Olszewska %A Kaisa Sere %T Towards Event-B Specification Metrics %X In this paper we describe our ongoing research on Event-B specification metrics. We focus on the physical features of specification, such as its vocabulary or length for the Event-B machines. We base our metrics on the syntactic properties of the Event-B language, namely operators and operands that we consider meaningful for our measurement model. Presented metrics are applied for a number of Event-B machines. Obtained results can be analysed in a perspective of an abstract machine and its refinements. %C Aix-en-Provence, France %D 2010 %P 81-86 %L deploy250
