The application of dynamic virtual prototyping to the development of control systems

A new method of developing control systems on the basis of dynamic virtual prototyping (DVP) has been proposed. The method facilitates the control system development process by means of (1) automating the transition from the conventional DVP of a plant to the dynamic model suitable for the control system design and (2) integrating the development process into the overall lifecycle. The method comprises the three principal stages: (1) representing the plant by its DVP; (2) simulating the DVP and generating the data-based model of the plant; (3) designing the control system using the generated data-based model. Stages 1 and 2 are supported by DVP systems (e.g. IGRIP, LMS/VirtualLab, MSC SimOffice), stage 3 is accomplished by CACSD. The proposed development method has been adapted to the class of plants that are linearizable, quasi-stationary, stable or stabilizable without using the analytical model and have lumped parameters. The specifics of applying the conventional methods of identification and control system design in the context of DVP have been revealed and analyzed. The engineering applicability of the method has been proved by means of developing the control system for fine positioning of a gantry crane load.reviewe

Business process modeling and simulation

The textbook provides the essentials of the Business Process (BP) Modeling and Simulation (M&S) from the verbal BP description to the formulation of the mathematical scheme of the model and the simulation program. Both the analytical modeling and the simulation approaches to BP M&S are considered. Special attention is given to the theoretical and practical aspects of the BP M&S. The text covers the following topics: fundamentals of the BP M&S, conceptual modeling using IDEF3 standard, cost metrics and the activity based costing, analytical modeling (queuing networks, linear and dynamic programming), simulation with GPSS, timed Petri Nets, and Crystal Ball toolkits. Case studies include BP simulations with BPwin and GPSS. The intended readers are senior graduate students and junior postgraduate students of computer science and industrial management

DISTRIBUTED AUTOMATION AND CONTROL SYSTEMS

Abstract – Distributed automation and control systems are considered from the implementation point of view. The role of middleware and, in particular, the object-oriented open-standard-based CORBA is discussed and its usefulness for system integration and communication abstraction is shown on a practical example of an experimental robotic system. 1

Integration of Human Factors methods to the ManuVAR Product Lifecycle Management model

It is necessary to acknowledge human factors (HF) more systematically throughout the lifecycle. Human factors engineering is a significant part of the product and system design process, but now it is time to widen the scope from design phase to cover all situations during the whole lifecycle. This paper aims to describe how to integrate HF methods into the Manu V AR Product lifecycle model (PLM) and how to make HF methods more visible and usable throughout the entire lifecycle. By dividing methods and services into four groups: (1) manage requirements, (2) support design, (3) evaluate and get feedback and (4) support training and sharing of information it is possible to respond to the needs and requirements of Manu V AR goals, lifecycle, gaps, cluster cases, high value, high knowledge manual work and technology applications
