Item ANSI/ISA 95 final capacity scheduling for software industry(2015-01-01) Vasilev P.The Scheduling in Software Industry is a matter that caused many studies and various approaches for solving this problem in the past few decades. Neither of these approaches uses as a framework the industrial standard ANSI/ISA 95 in which the models for Capability, Scheduling and Execution are tightly connected with the needed Resources and their availability. In this research the matter of Final Capacity Scheduling using the standard ANSI/ISA 95 as a framework is discussed. Examples are given for using ISO 22400 Key Performance Indicators in the calculation of some important for the Scheduling process parameters.Item Design of a Multifunctional Operating Station Based on Augmented Reality (MOSAR)(2021-03-01) Ivanova V.; Vasilev P.; Stoianov I.; Andreev R.; Boneva A.Design principles of a novel Multifunctional Operation Station (MOS) using Augmented Reality (AR) technology (MOSAR) are proposed in this paper. AR-based design allows more ergonomic remote instrument control in real time in contrast to classical instrument-centered interfaces. Another advantage is its hierarchical software structure including multiple programming interpreters. The MOSAR approach is illustrated with a remote surgical operating station that controls intelligent surgical instruments. The implementation of the Operation Station (MOS) is based on the multiplatform open-source library Tcl/Tk, and an AR extension has been developed on a Unity platform, using Vuforia SDK.Item IEC 62264 standard-based manufacturing operations management resource modelling for electron beam welding(2023-01-01) Vasilev P.; Koleva E.The development and deployment of a Manufacturing Operations Management (MOM) system for electron beam welding aims the integration and organization of the accumulated knowledge for the process, and the application of this knowledge for the improvement of the modelling and control capabilities, their efficiency, adaptability, flexibility and re-configurability, as well as integration with other technological processes. The paper presents the Unified Modelling Language (UML) information modelling of electron beam welding installation as a part of an IEC 62264 standard-based manufacturing operations management system development.
