        The increase in the complexity of computer systems has led to a vision of systems that can react and adapt to changes. Organic computing is a bio-inspired computing paradigm that applies ideas from nature as solutions to such concerns. This bio-inspiration leads to the emergence of life-like properties, called self-* in general which suits them well for pervasive computing. Achievement of these properties in organic computing systems is closely related to a proposed general feedback architecture, called the observer/controller architecture, which supports the mentioned properties through interacting with the system components and keeping their behavior under control. As one of these properties, self-configuration is desirable in the application of organic computing systems as it enables by enabling the adaptation to environmental changes. However, the adaptation in the level of architecture itself has not yet been studied in the literature of organic computing systems. This limits the achievable level of adaptation. In this paper, a self-configuring observer/controller architecture is presented that takes the self-configuration to the architecture level. It enables the system to choose the proper architecture from a variety of possible observer/controller variants available for a specific environment. The validity of the proposed architecture is formally demonstrated. We also show the applicability of this architecture through a known case study. Manuscript Document

        Lately, one of the biggest challenges in enterprise is the strategic alignment of information technology with business. Enterprises use various methods to achieve this strategic alignment. Enterprise architecture is an effective approach that allows optimal management of Enterprise’s information technology and strategic alignment of IT functionalities and business requirements. These days, considering dynamic environments, there is the possibility of any kind of change in enterprise’s conditions, especially after implementation of Enterprise architecture. This change of conditions demonstrates itself in a variety of forms. In these cases, decision making should be done as an appropriate response to these changes which should be predictable. Otherwise it would lead to lack of proper response and consequently, readjustment of Enterprise architecture document, which imposes many human and financial costs on the enterprise. In addition, the enterprise’s progress toward competitive advantages will be stopped. The appropriate response and adaptability to these changes is a concept represented under the title of adaptive maintenance of Enterprise architecture. In the following article with the help of a software maintenance method and examining the possibility of extending into the Enterprise architecture maintenance, through a case study on Power Distribution Company of Golestan province, it is shown how the improvement of adaptive maintenance of Enterprise architecture can be assisted and the possibility of implementation of various types of changes in business and information technology without disturbing the Enterprise is provided.
