Conference Paper
Full-text available
An engineering support system for process simulation of actuations of machine working parts in reconfigurable manufacturing system (RMS) is presented. Hardware and software requirements are specified. The system provides opportunities for research of the behavior of RMS working parts without any limitations of dimensions and shapes of processed sur...
Conference Paper
Full-text available
In this paper the development of Information Modeling techniques in the Power Engineering is analyzed and discussed. The proposed functional model is one of the first steps in becoming an open, interoperable, distributed and intelligent enterprise model. The model is based on the combination of PERA and GERAM reference architecture by using the sta...
Conference Paper
Full-text available
In order to improve and extend the knowledge in the field of modeling, simulation, control and optimization of EBMR plant, the development and usage of different engineering tools and their integration to ESS is needed. For these purposes the current advances in the field of ICT such as reference frameworks and architectures, information modeling l...
Conference Paper
Full-text available
Enterprises need to adapt increasingly fast and flexible to changing customer requirements and business goals. Enterprise modeling plays a central role in this process. In this paper enterprise modeling requirements are identified according to the Generalized Enterprise Reference Architecture. The applicability of IDEF methodology for enterprise mo...
Article
Full-text available
Abstras. A In this paper a semantic approach for achieving interoperability, data and information integration in Manufacturing Operation Systems (MOM) is presented. The suggested approach is based on collaborative use of ontologies, relational databases, and ISO/IEC62264 standard for design and integration of systems. The developed ontology­based a...
Article
Full-text available
Ontologies play an important role at all stages of the development of information and control systems providing semantics for unambiguous information exchange among different autonomous agents. The main goal of the paper is to present domain ontology for electron beam melting and refining (EBMR) of metals and alloys. The model is integrated within...
Article
Effective integration between manufacturing execution systems and business and logistics systems has been of great interest for a long time. Essential part in enterprise integration is the task of optimal planning and scheduling. An ontological approach consisting of integrated ontologies: a core meta-ontology, according to ANSI/ISA S95 standard an...
Article
Full-text available
In this paper a new concept of Virtual Enterprises is discussed and the actual state of the art in this field is analyzed. In the development process of VE open integrated Information system an activity information model is needed. For this purpose and according to the suggested by IFAC/IFIP Task Force Enterprise Reference model, an IDEF0 informati...
Article
The approach of Generalized Nets is used for flow data modelling in the process industry. Because of imprecise measurements in industrial plant operation, the theory of Intuitionistic Fuzzy Sets is applied. The Intuitionistic Fuzzy Generalized Nets model for natural gas distribution is presented. The model could be used as a part of the Production...
Article
Full-text available
In this paper the main tendencies in the current development of SMEs are presented and analyzed. On this base is proposed to follow and apply the Continuous Acquisition and Life Cycle Support (CALS) technologies for integration of production with the integrated information tools. Using this global strategy an open architecture for e-business (ECOS)...
Article
Full-text available
This paper presents the worldwide trends of standardization processes in the time of growth economic integration and progressive implementation of Computer Aided Engineering (CAE) tools. A summary of main functions and types of industrial standards and characteristics of integration processes are discussed. The new perspectives for product data exc...
