Nowadays the most developed methodology and instrumental modeling environment is ARIS (Architecture of Integrated Information Systems) by IDS Scheer, the company, which represents the result of mergering of two companies: Software AG and IDS Scheer. The Disadvantages of Modern Instrumental Modeling At the same time the method of modeling information systems and databases described in State Standard (1) and based on interpreted predicate logic, can' t be applied to the description of an application domain and to the modeling of various process management problems.
There is no universal method of solving a problem that appears in the process of modeling and describing corporation and its systems in the development of visual tools, which aim to improve representation knowledge in graphical form. The expressiveness of all supported models doesn' t have sufficient power to represent all aspects, laws, limitations and patterns of such an application domain as corporate management systems. However, nowadays enterprise modeling tools maintain only conceptual level and formal level is hardly represented. TOGAF (The Open Group Architecture Framework) assigns four major architectures: business architecture, applications architecture, data architecture, technology architecture. For example, the Zachman framework divides the application domain according to the aspects of stakeholders. It helps to find a proper decision while designing the initiatives above and thus improving them.Īt the present time there is a great number of methodologies, methods, models, languages and tools to describe activity of an enterprise due to different perspectives. Object modeling is to estimate design decisions.
One of the most important challenges every company faces is designing organizational and functional structures, developing mechanisms, instruments and processes of management to raise the business effectiveness. Key words and phrases: modeling, ARIS, enterprise modeling instruments, integrated notation, logical models, formal models. There is an example of an integrated notation, containing such notions as " Event" and " Condition", and also an example of using the formal level of application domain to estimate the completeness and the consistency of the models mentioned. This article deals with the research of enterprise modeling instrument' s disadvantages and its ways of possible development.
