One of the modern paradigms to develop Software is object-oriented analysis and design. In this paradigm, there are several objects in the Software, and each object plays some specific roles. There is a sequence of activities to develop an analysis model. In the first step, this study works to develop an initial use case model. Then, in the second step, a number of concepts are identified, and a glossary of participating objects is built. Identifying attributes of objects (and classes) is one of the most important steps in the object-oriented paradigm. This paper proposes a method to identify the attributes of objects and verify them. The method is also concerned with classifying and eliminating the incorrect attributes of objects. Then, the method is evaluated through a large application, a Control Command Police System. After that, several guidelines concerning attributes of objects based on the practical experience obtained from the evaluation are provided.

Agent technology enhances the ability of Software engineers to develop open, complex and distributed applications and now an increasing number of problems in industrial, commercial, medical and Networking application domains are being solved by agent-based solutions. In developing these solutions, practitioners need appropriate methods, techniques and tools. In this paper, we introduce and justify agent-oriented Software engineering as a layered technology. The layers of this technology are quality, agent oriented Software development process, agent-oriented methods, agent-based system architecture and agent development tools. This pragmatic approach will help developers and project managers to remove many pitfalls of agent-oriented Software development, helps researchers to determine the existing gaps in the current works and helps tool developers to organize their efforts for constructing agent-based tools. On the basis of this approach, an investigation on the current works in agent-oriented Software engineering is presented. In this paper, umbrella activities for complementing the main activities and steps in the agent based development are introduced and described and a new classification and definition of testing activities for agent based systems is presented.

Distribution in dynamic multi-agent systems is only justifiable if there is a level of localization guaranteed by the system for each domain the agents represent. Adaptive Agent oriented Software Architecture (MOSA) is a new dynamic approach to Software design based on agent oriented architecture. In this approach, agents are considered as adaptively communicating concurrent modules which are divided into white box modules, responsible for the communications as well as learning, and black box modules. Responsible for the independent specialized processes of the agent. A distributed learning policy that takes advantage of this architecture is used for the purpose of system adaptability. Then a method is proposed to ensure the localization of responsibilities in this multi-agent methodology.

Software architecture is one of the most fundamental products in the process of Software development in the areas of behavioral or non- behavioral features like availability or transformability change. There are different ways to evaluate Software architecture one of which is the creation of application model. An executable model of Software architecture is an official description of architecture which if used prior to the running of architecture, its final behavior and function will be observed and as a result possible problems could be elevated and promoted. In this study we aimed at availability evaluation in object- oriented style.To ensure the applicability of the style the UML diagrams, especially the sequence diagram, were used to exhibit the architectural behavior. In the later stages, as the UML diagram is inapplicable, the following operations were done. First, metric annotation is used to tag clichés. Then, the studied style diagram was transformed into an applicable one. Afterwards and following the design of petri, using CpnTools, the applicable model based on color petri net was evaluated. In this research the availability evaluation on an ATM for the N=5 users was tested and the results of evaluation showed that the higher the rate of availability (approximately %100) the higher is the rate of usability of the system when needed.
