Моделирование структурной организации единого информационного пространства предприятия-разработчика микроэлектронных систем

Abstract

During the process of forming a unified information space (UIS) is widely used modeling of information exchange facilities and UIS infrastructure. Despite the large variety of approaches to modeling a UIS, in particular using the design structure matrix method, the proposed solutions do not provide a direct link between elements of the described structure and hardware and software equipment. Also, existing approaches for modeling the UIS do not take into account possible external and internal constraints imposed on the placement of UIS components in the enterprise space. The paper proposes an approach to formalizing the UIS structure of the microelectronics design center, which is intended to eliminate these shortcomings. The structure of the UIS according to a parallel organization model includes following main components: a product data management system, participants of the microelectronic system design process, data-processing hardware and software. The structure of the UIS as a dynamic system can be reduced to a generalized model that includes the set of subscribers – participants of the design process, primary and secondary data-processing tools and objects of information exchange. The mathematical description is made using elements of theory of sets, matrices and queuing systems. The proposed model takes into account the constraints that affect a form of implementation of the UIS structure, as well as many characteristics of software and hardware. Simulation modeling of the UIS structural organization, presented as a set of multichannel queuing systems, helped to draw conclusions about bandwidth and reliability of considered variants for the UIS organization based on proposed hardware (the server solution) and software (the database management system) tools that are being used.
