Equation-Based

Abstract. EOOLT’2007 was the first edition of the ECOOP-EOOLT workshop. The workshop is intended to bring researchers associated with different equa-tion-based object-oriented (EOO) modeling languages and different application areas making use of such languages together. The aim of the workshop is to ex-plore common grounds and derive software design principles that may make fu-ture EOO modeling languages more robust, more versatile, and more widely accepted among the various stakeholders. At EOOLT’2007, nineteen research-ers with diverse backgrounds and needs came together to present and discuss fourteen different concept papers grouped into the four topic areas of integrated system modeling approaches; hybrid modeling and variable structure systems; modeling languages, specification, and language comparison; and tools and methods. 1 Objectives and Call for Papers Computer aided modeling and simulation of complex systems, using components from multiple application domains, such as electrical, mechanical, hydraulic, control
