From the Publisher: The complete engineering resource for implementing the NIST real-time control systems software library The National Institute of Standards and Technology (NIST) real-time control systems (RCS) library is a highly useful tool for engineers developing and implementing hierarchical and distributed real-time control systems. This book serves as a user's guide for development engineers using the software library in industrial applications. The RCS Handbook is divided into three parts. The first section provides a tutorial introduction to RCS that discusses the RCS design methodology and the Reference Model Architecture (RMA) on which the RCS library is based. The second section serves as an RCS handbook for applications engineers and features two illustrative design examples, coverage of issues in programming in Neutral Message Language (NML), and discussion of code generation and architecture files. The third section provides helpful appendices that provide useful background information on the C++ language, compilers and makefiles, and general operating system concepts. Suitable as a primary text for a course in real-time control or as a professional reference, The RCS Handbook is a one-of-a-kind resource that provides unparalleled coverage of the RCS library and practical solutions in high-tech automation. Author Biography: VEYSEL GAZI, MATHEW L. MOORE, and KEVIN M. PASSINO are at The Ohio State University in Columbus, Ohio. WILLIAM P. SHACKLEFORD, FREDERICK M. PROCTOR, and JAMES S. ALBUS work at the National Institute of Standards and Technology in Gaithersburg, Maryland.

In this paper we consider a real-time multiserver (such as machine controllers) and multichannel (such as regions and assembly lines) systems involving maintenance. Our objective is to fit these systems into the framework of queueing models and thus to justify the use of the powerful queueing theory analytical methods in the analysis of real-time systems. The main difficulty is that real-time systems by their very nature do not permit queues. To resolve this contradiction we use a dual approach in which we consider jobs as servers and servers as jobs. We adjust the traditional definition of availability for the real-time systems under consideration and show how to compute the system's availability, when both service and maintenance times are exponentially distributed (birth-and-death process). At this stage we restrict ourselves to a worst case (maximum load regime), which is most typical in high-performance data acquisition and control (production and military) systems.

[Auto Generated] real-time systems refer to systems that have hard real-time requirements for interacting with a human operator or other agents with similar time-scales. An efficient simulation of real-time systems requires a model that is accurate enough to accomplish the simulation objective and is computationally efficient [1, 2]. We define model accuracy in terms of the ability of a model to capture the system at the right level of detail and to achieve the simulation objective within an all

We obtain an optimal operation policy for a general n-server (channel, machine) stand-by system involving preventive maintenance and operating in realtime. We show that such a policy is achieved by successive total use of each server capacity, and does not depend on the arrival pattern of processed data and task duration. We show also that this policy is optimal for any finite, initial period of time, and not only in the sense of long-run availability. The analysis is performed in two stages: a worst-case analysis is performed, and then, a general case is treated. Such a consecutive approach also seems to be useful in the analysis of more complicated systems. Rigorous mathematical proofs are provided. Actual and possible applications of results to military and production control systems are discussed.
