Formal Development of a Washing Machine Controller Model Based on Formal Design Patterns
نویسندگان
چکیده
Formal methods approach to software construction can significantly increase the reliability and correctness of the resulting software. Formal methods users are given sophisticated languages and tools for constructing software models, but they often lack some systematic methodological measures to help. Formal design patterns can help formal methods users speed up the development process by re-using and incorporating some pre-defined proved and refined models, as design patterns do in object-oriented software. Some formal design patterns are presented and applied to the development of a washing machine controller model in Event-B that is a formal method for modeling and reasoning about complex discrete system. Key-Words: Formal methods, Event-B, Design Patterns, Washing Machine Controller

Developing Reliable yet Flexible Software through If-Then Model Transformation Rules
Developing reliable yet flexible software is a hard problem. Although modeling methods enjoy a lot of advantages, the exclusive use of just one of them, in many cases, may not guarantee the development of reliable and flexible software. Formal modeling methods ensure reliability because they use a rigorous approach to software development. However, lack of knowledge and high cost practically fo...

In this paper, a new broadcast encryption scheme is presented based on threshold secret sharing and secure multiparty computation. This scheme is maintained to be dynamic in that a broadcaster can broadcast a message to any of the dynamic groups of users in the system and it is also fair in the sense that no cheater is able to gain an unfair advantage over other users. Another important feature...
متن کاملA Formal Petri Net Based Model for Antivirus Update Agent System
In this paper, a formal model for antivirus update agent system is presented based on mobile agent technology and predicate/transition Petri nets. The mobile agent system contains two mobile agents called DCA and UNA. It sends out agents to update antivirus on client computers in a network. Each agent takes on a specified responsibility. First, DCA roams through the network and check the last d...
