Production management systems

Khokhlov A.S., Mishutin D.Yu., Baulin E.S.  Methodological aspects of model reengineering for oil refineries and petrochemical plants

The reengineering of production models at oil refineries, petrochemical and similar plants and their and application practice show the key handles for improving production effectiveness and user competence. The paper discusses the specificity of models used in planning and scheduling systems of oil refining and petrochemical industries. It offers a network model maintenance structure including a virtual team of specialists from various enterprise departments headed by an independent coordinator. This approach can be extended to vertically integrated oil companies and petrochemical clusters.

Keywords: reengineering, production model, information and communication technologies, feedback, self-regulation, virtual team, production plan, optimization, linear programming, planning, scheduling by days, scheduling by hours, aggregation, schedule update, additivity, asynchrony, oil refining.

Molchanov A.Yu.  Web interface application in asset management information systems

Present-day management information system for enterprise physical assets presumes the connection with maximum possible number of asset management participants. To that end, the functionality of such system should be available for a variety of hardware. Web interface offers a versatile solution to the problem. The paper overviews Web interface hardware and organization features in asset management information systems.

Keywords: physical asset, EAM, distributed computing, Web interface.

Kolesnikova O.V., Lelyukhin V.E.  Automation of custom production management on the basis of digital twins

The paper discusses the results of theoretical research, development and implementation of enterprise management systems using hybrid technologies based in digital twins aligned with Industry 4.0 concepts. It presents the original concept of production management at an engineering plant using and integrated control core implemented as a digital production twin. At any moment, the control core represents the current state of production process of the whole enterprise. System is based on program control scheme with real-time correction of deviations from the program independent on their origin.

Keywords: mechanical engineering, custom production, production automation, integration of control, control core, digital twin.

Brom A.E., Maslennikova Yu..L.  Assessment of organizational stability of pilot production with reference to order execution priority

The paper offers an approach to the assessment of the organizational stability of pilot production, which allows for the changes in order execution priority and the number of machine tool switches for specific component parts. It substantiates the introduction of weight factors reflecting the priority change costs. The values of weight factors and organizational stability index in various production situations are analyzed using the orders base of the pilot production of the Central Scientific Research Automobile and Automotive Engines Institute.

Keywords: organizational stability, pilot production, short-term planning, orders priority, mechanical engineering, automation.

Kamakin A.N., Vasilkov Yu.V.  Standard warehouse automation solutions for in-process storage of semifinished workpieces
