Modeling and estimating system availability : special report by D. P Gaver( Book )

2 editions published in 1976 in English and held by 5 WorldCat member libraries worldwide

A variety of probability models for single and multiple unit, failure-prone but repairable, systems are reviewed. The purpose of the paper is to provide methods for expressing the uncertainties in system availability in terms of uncertainties in component parameters. A log-linear transformation and the 'jackknife' are shown to be effective. (Author)
Probability models for multiprogramming computer systems by D. P Gaver( Book )

2 editions published in 1966 in English and held by 3 WorldCat member libraries worldwide

A probability model is developed for a computer system that is capable of multi programming, i.e., that maintains several program segments simultaneously in Main Memory (core), the latter being served by several input-output channels. Under various probabilistic assumptions, reflecting the mixture of jobs submitted to the system, the productivity of systems of various configurations is studied. (Author)
Finite birth-and-death models in randomly changing environments by Donald Paul Gaver( Book )

2 editions published in 1982 in English and held by 3 WorldCat member libraries worldwide

This report provides computational methods for studying properties of birth-death processes whose transition rates (infinitesimal generator) varies in accordance with a random, 'environmental', process. In particular, the models may be used to represent the availability fo redundant systems subject to external shocks or other 'common cause' failures. These models also represent search for an object when the search environment (e.g. weather) varies randomly in time. (Author)
Analysis of exception data in a staging heirarchy by D Gaver( Book )

3 editions published in 1974 in English and held by 2 WorldCat member libraries worldwide

This paper is concerned with the analysis of program address trace data in a demand paged computer system having a three level staging hierarchy. Our primary objective is to explore the data both graphically and numerically, using methods that may be useful when other data traces become available. A secondary objective has been to fit plausible point-process type models to the data. It is believed that the present approach, combining data-analytic procedures with probability modeling, will prove useful in understanding program behavioro and htus aid in the rational design of complex computer systems
Channels that Cooperatively Service a Data Stream and Voice Messages. I by Donald Paul Gaver( Book )

2 editions published in 1979 in English and held by 2 WorldCat member libraries worldwide

A system of channels cooperatively services both voice and data messages arriving at one node of a communications network. This paper is devoted to the analysis of a particular channel-sharing strategy, in which voice traffic always occupies its channels when available, but data service is allowed to occur on empty voice channels. Voice traffic is taken to be of high priority; voice arrivals that find all voice channels busy are treated as losses. Note that voice traffic will be relatively infrequent as compared to data, and will also exhibit relatively long holding (service) times. Data traffic is taken to be heavy, and exhibits very short holding times (per word unit): compared to voice, data appears to arrive nearly continuously; when all data (and empty voice) channels are filled, queueing occurs
Diffusion Approximations for the Cooperative Service of voice and Data Messages by John P Lehoczky( Book )

2 editions published in 1980 in English and held by 2 WorldCat member libraries worldwide

A probability model is presented for a set of communication channels that share the service of data and voice transmissions. A diffusion-theoretic approximation is derived, utilizing new results of Burman (1979). It is shown that the data queue (which is of low priority relative to voice) is approximated by a Wiener process. (Author)
Storage Problems When Demand is 'All or Nothing' by Donald Paul Gaver( Book )

2 editions published in 1979 in English and held by 2 WorldCat member libraries worldwide

An inventory of physical goods or storage space (in a communications system buffer, for instance) often experiences 'all or nothing' demand: if a demand of random size D can be immediately and entirely filled from stock it is satisfied, but otherwise it vanishes. Probabilistic properties of the resulting inventory level are discussed analytically, both for the single buffer and for multiple buffer problems. Numerical results are presented. (Author)

Channels That Cooperatively Service a Data Stream and Voice Messages. II. Diffusion Approximations by John P Lehoczky( Book )

2 editions published in 1979 in English and held by 2 WorldCat member libraries worldwide

A system of channels mutually accommodate both data and voice messages, voice having preemptive priority but being a loss system, and data being allowed to queue. Approximations to the data queue properties are derived. (Author)
Analytical Models for Mobile Sensor (UAV) Coverage of a Region( Book )

2 editions published in 1998 in English and held by 2 WorldCat member libraries worldwide

The effective use of mobile sensors (UAVs for example, but not exclusively) to investigate own and opponent force status in geographical regions requires planning to compensate for their limitations. These limitations include finite endurance, and realistic mission unreliability: the failure propensities of platform and sensing packages, and the consequent need for maintenance and logistics support. This paper supplies analytical (mathematical) models (AMM) to assist planners, and the acquirers and operational testers of mobile sensor assets. The results are formulas (that can be quickly evaluated numerically) for the expected time on station (fraction of time a region has sensor presence) of several cooperatively operating systems supported by several maintenance facilities. These results can be used to estimate the number of sensors of a particular type needed to cover a region adequately. Limited evidence indicates usefully satisfactory agreement between analytical model estimates and those from more detailed and elaborate Monte Carlo simulations (MCS)
Time-dependent delays at traffic merges by D. P Gaver( Book )

3 editions published in 1966 in English and held by 2 WorldCat member libraries worldwide

The expected delay of a side-road driver attempting to merge with, or cross, a main-road traffic stream is studied. The model includes the effect of mixture of 'slow' and 'fast' drivers at the side road, and of different gap acceptance probabilities. Numerical results show the manner in which long-run delays are approached, and an approximation to the transient behavior of delays is studied. (Author)
Channel blocking in a satellite communication system model by Donald Paul Gaver( Book )

2 editions published in 1978 in English and held by 2 WorldCat member libraries worldwide

A model is constructed for a communication system that involves a single satellite and many ground stations. The probability that messages are blocked is studied

First order autoregressive gamma sequences by D. P Gaver( Book )

1 edition published in 1978 in English and held by 1 WorldCat member library worldwide

An autoregressive model that generates Markov correlated time series is described. The time series have exponential or gamma distributed marginal distributions. Various properties of these time series are investigated
Approximate Models for Processor Utilization in Multiprogrammed Computer Systems by Thomas J. Watson IBM Research Center( Book )

1 edition published in 1972 in English and held by 1 WorldCat member library worldwide

The paper presents results of an approximation study of cyclic queueing phenomena that occur in multiprogrammed computer systems. Based on Wald's Identity and using ideas of diffusion, the objective is to develop convenient and nearly explicit formulas relating processor use in such systems to simple program parameters and the level of multiprogramming. Some numerical results to indicate the quality of the proposed approximation are given. (Author)
Index policies for shooting problems( Book )

2 editions published in 2006 in English and held by 1 WorldCat member library worldwide

We consider a scenario in which a single Red wishes to shoot at a collection of Blue targets, one at a time, to maximise some measure of return obtained from Blues killed before Red's own (possible) demise. Such a situation arises in various military contexts such as the conduct of air defence by Red in the face of Blue SEAD (suppression of enemy air defences). A class of decision processes called multi-armed bandits has been previously deployed to develop optimal policies for Red in which she attaches a calibrating (Gittins) index to each Blue target and optimally shoots next at the Blue with largest index value. The current paper seeks to elucidate how a range of developments of index theory are able to accommodate features of such problems which are of practical military import. Such features include levels of risk to Red which are policy dependent, Red having imperfect information about the Blues she faces, an evolving population of Blue targets and the possibility of Red disengagement. The paper concludes with a numerical study which both compares the performance of (optimal) index policies to a range of competitors and also demonstrates the value to Red of (optimal) disengagement
