This paper aims to provide a formal framework that supports an incremental development of dynamic systems such as multi agents systems (MAS). We propose a fuzzy labeled transition system model (FLTS for short). FLTS allows a concise action refinement representation and deals with incomplete information through its fuzziness representation. Afterward, based(More)
This paper aims to provide a general framework for the design of complex systems such as multi-agents systems (MAS). It is based on formal specification model which supports MAS requirements. This model, called Open Fuzzy Synchronized Petri Net (OFSyPN), is an extension of Synchronized Petri net enhanced by fuzziness, openness and interaction with(More)
The formal stepwise refinement method is a powerful manner to design complex systems. It postulates system engineering gradually by starting from initial abstract specification and follows a rigorous refinement process to establish final specification. Fuzzy Labeled Transition Refinement Tree (FLTRT) is introduced to fulfill such purpose. It supports(More)
Fuzzy Labeled Transition Refinement Tree (FLTRT) is a rigorous refinement model which supports abstraction and handling incomplete information and by the way reducing complexity of refinement process. It is based on Fuzzy Labeled Transition System (FLTS) which is a generalization of well-known Labeled Transition System, enhanced by fuzziness facility. The(More)
