Estimating aircraft recoverable spares requirements with cannibalization of designated items by
Donald P Gaver(
Book
)
4 editions published in 1993 in English and held by 91 WorldCat member libraries worldwide
To estimate requirements for primary operating stocks (POS) of aircraft recoverable spare parts, the Air Force has not, as a matter of policy, assumed that parts shortages can be consolidated among aircraft (cannibalized). It has, however, assumed perfect consolidation of shortages in its computation of war readiness spares requirements, designating which parts are relatively easy to cannibalize and which are not. The research described in this report shows that a policy of designated cannibalization in estimating POS requirements is costeffective. The authors present a computational model that incorporates designated cannibalization, determining the probability of meeting a specified aircraft availability goal with a specified confidence. They conclude that a designated cannibalization policy for POS can reduce safety stock requirements while maintaining traditional levels of system performance

Donald P Gaver(
Book
)
5 editions published between 1976 and 1977 in English and held by 8 WorldCat member libraries worldwide
A variety of probability models for single and multiple unit, failureprone 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 loglinear transformation and the 'jackknife' are shown to be effective. (Author)

Approximate Models for Processor Utilization in Multiprogrammed Computer Systems by
Donald P Gaver(
Book
)
3 editions published in 1972 in English and held by 3 WorldCat member libraries 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)

Modeling the operation of a platoon of amphibious vehicles for support of operational test and evalution (OT & E) by
Donald P Gaver(
Book
)
4 editions published in 2001 in English and held by 3 WorldCat member libraries worldwide
This report documents an analytical model to assist in the planning of the Operational Test and Evaluation (OT & E) of the Marine Corps' prospective Advanced Amphibious Assault Vehicle (AAAV). The model's emphasis is on suitability issues such as Operational Availability in an onland (after ocean transit) mission region. The model predicts strong sensitivity to the form of an assumed distribution of times to vehicle breakdown, and hence recommends that appropriate test data be obtained to reveal that form (the mean alone is inadequate). Removal of design faults likely to cause early failures is encouraged. The AAAV design is for a relatively lightweight but technologically advanced (mobile and lethal) amphibious vehicle that operates in platoons. If individual vehicles break down they must often be transported for repair, for example, to their point of origin, a ship. One option is to allow another platoon member to tow; another is to assign an auxiliary vehicle to transport. Such duties may seriously diminish the platoon productive mission availability (the towing/transport agents may themselves fail). OT & E should be designed to fully test for the systemwide effect of force (platoon, and beyond) sustainability requirements

Stochastic properties of peertopeer communication architecture in a military setting by
Donald P Gaver(
Book
)
2 editions published in 2005 in English and held by 2 WorldCat member libraries worldwide
A timecritical military mission must be completed before a random deadline to be successful. The mission requires a number of Blue assets; the more assets that can be assembled before the deadline, the greater the possibility of mission success. Traditionally, military Command and Control (C2) has a hierarchical structure; information is centrally stored and decision makers are also centralized. The paradigm of NetworkCentric Warfare (NCW) implies a more horizontal C2 structure. There is often little communication infrastructure on the battlefield. PeertoPeer (P2P) communication networks are attractive enablers of a horizontal C2 structure. A stochastic model is used to discuss the benefits and possible vulnerabilities of a P2Penabled C2 structure for a timecritical mission. The P2P architecture can result in larger probabilities of mission success than centralized C2. However, its benefits are nullified if the time it takes to assemble the needed Blue assets becomes larger than that for the centralized C2

Models for transmission and control of bioterroristic epidemics(
Book
)
2 editions published in 2004 in English and held by 2 WorldCat member libraries worldwide
A deterministic model for control of a bioterrorist epidemic in a large nonhomogeneous population is presented. Primary considerations in model development are the representation of a large nonhomogeneous population of individuals and the implementation of the model for quick numerical execution. The model represents the effect of mass prevaccination and mass vaccination during the epidemic. It is recognized that the vaccination can result in life threatening complications. The model also represents the effect of tracing and quarantining as control options. The model has been implemented in Java for a Webbased educational tool. Numerical examples (p. 1215) illustrate possible behavior of populations exposed to such a disease as smallpox. Various disease controls such as vaccination and case tracing are studied

Assessing and Controlling the Availability of FailureDegraded Service Agents by
Donald P Gaver(
Book
)
3 editions published in 1998 in English and held by 2 WorldCat member libraries worldwide
Military items such as airborne surveillance systems (UAVs, JSTARs, helicopters, etc.) or combat vehicles (tanks, APCs, ships) may have high effectiveness when available on station, but require occasional restoration (refueling, rearming, scheduled maintenance) and repair after unscheduled failures of certain subsystems. This requirement takes them off station, where delays occur that are affected by the numbers and types of support resources and the philosophy of scheduling those resources. This paper considers the effect of decision choices on longrun item availability on station when items can be in several levels of capability/effectiveness when on station. The model is used to show that a simple binary decision rule (that depends on ratios of endurance, failure, and restoration and repair rates) guides the decision as to whether a failed item should be completely repaired to its highest level, or returned to duty at an incompletelycapable state. View this as an indicator of the types of rules anticipated to apply in realistic generality. These will be the subject of additional research

Book
)
2 editions published in 1972 in English and held by 2 WorldCat member libraries worldwide
The decision as to whether a medical doctor, or other expensive specialist, should be carried aboard ship depends upon demand for service, consequences of not providing this service, and cost of providing the service. A simple preliminary mathematical model to aid in making this decison wisely is presented. (Author)

The analysis of shooting problems via generalised bandits(
Book
)
2 editions published in 2004 in English and held by 1 WorldCat member library worldwide
A single Red wishes to shoot at a collection of Blue targets in order to maximize some measure of return obtained from Blues killed before Red's own demise. While the class of decision processes called multiarmed bandits has been previously deployed to develop optimal policies for Red, we argue the importance of a little known, but more general class of bandit processes introduced by Nash (1980). In particular, the deployment of this class of processes will enable Red to take account in a natural way of the relative threats posed to his own survival in taking targeting actions. We develop optimal shooting policies for Red in the context of a range of models, which are of independent interest. The paper concludes with a numerical study

Battlespace/Information War (BAT/IW): A SystemofSystems Model of a Strike Operation by

Book
)
3 editions published in 2002 in English and held by 1 WorldCat member library worldwide
This paper presents a lowresolution, highlevel modeling methodology for the analysis of the effectiveness of a Blue system of systems operating in a battlespace. The methodology enables quick turn around and efficient exploration of sensitivities of measures of Blue combat success to realistically imperfect Blue intelligence, surveillance and reconnaissance capabilities: limited and imperfect sensor surveillance and reconnaissance, particularly battle damage assessment (BDA), and finite, hence saturable, communications and weapons delivery capability. The model explicitly represents aircraft sorties, fires, sensor/shooter latencies, target losses, imperfect target type classification, imperfect weapon assignment, and BDA; various levels of the above imperfections can be applied, facilitating tradeoff studies, The model is deterministic/expected value in nature, although it analytically represents timedependent stochastic features such as system saturability. Model experimentation suggests the following results. Decreasing shooter latency can result in greater attrition than correspondingly increasing the probabilities of correct BDA or weapon assignment, although at the expense of a greater number of weapons fired per target killed. Erroneous BDA returns dead targets to the shooter targeting list. These dead targets not only result in wasted weapon expenditure but also take sensor/shooter resources away from legitimate live targets. Increasing the probability of correct BDA can result in a greater number of targets killed during a time period than increasing the probability of correct weapon assignment

Stochastic Models for Promoting and Testing System Reliability Evolution by
Donald P Gaver(
Book
)
3 editions published in 2001 in English and held by 1 WorldCat member library worldwide
Many systems and systemsofsystems function in sequentialstage fashion, and are constantly on when operative, but are failuresusceptible. Communication systems, power generation and transmission, and vehicular transportation systems tend to fall into this category. We propose a reliability growth model for such systems that is based on design defect removal under a TestFixTest (TFT) protocol: a system is assembled and put under test, for example for a fixed mission time, or multiple thereof. If the system fails during the test time its failure source in some stage is diagnosed, the stage is redesigned, and the new prototype system reassembled (system design is 'fixed') and the system is retested. The test (TFT) process is repeated until a predetermined test period elapses with no failures. This is analogous to the runtest criteria analyzed for oneshot devices 1. In this model we also allow for occasional defective redesign: response to a test failure can actually (and realistically) increase the number of failuregenerating design defects. Our model allows quick numerical assessment of TFT operating characteristics, given defining parameter values. It thus provides a planning tool for test designers

DISCOTIC: A DiscreteTime Analysis MetaModel for Use in Combat Systems Studies that Utilize HighResolution Simulation
Models by
Donald P Gaver(
Book
)
3 editions published in 2000 in English and held by 1 WorldCat member library worldwide
This paper provides various metamodels for extending or extrapolating in time, and varying and enhancing in coverage capability, the 2day output of a highresolution simulation model, here specifically but not exclusively, the Army's COSAGE. The models we propose, generically called DISC0TIC, (DiscreteTime Analytical Meta Model) are tailored to employ the discretetime output of COSAGE and, potentially, many other such models. The model parameters are estimated from data available from a highresolution simulation model; in the case of COSAGE the killer/victim scoreboards are used. The models are used to compute/estimate, in spreadsheet format, future force sizes and compositions that result from mutual attrition, as well as ammunition expenditures. Metamodel examination can and is shown to reveal apparent anomalies in data. Metamodels that reflect environmental variations and adaptable firing (ATCALlike) firing rates illustrate those effects for long (8day) battles

Methodology for an OperationallyBased Test Length Decision by
Donald P Gaver(
Book
)
3 editions published in 1997 in English and held by 1 WorldCat member library worldwide
Weapon systems that function destructively (e.g. missile or torpedo) are to be acquired in a lot of size m. Acceptance of the lot is based on the result of an operational test, administered to part of the lot if the test results indicate positive operational value the lot is accepted and the remaining part of the lot if fielded; otherwise the lot is 'rejected'. A test plan is designed that establishes an optimal number of weapon copies to test, given (models of) the operational gain of the fielded weapon under two tactical options, and the uncertainty in the weapon's predicted probability of success after the test is complete. The major test objective is to realize possible operational utility from the lot of items, and secondarily to demonstrate arbitrary levels of certainty

A new piece of equipment has been purchased in a lot of size m. Some of the items can be used in destructive testing before the item is put into use. Testing uncovers faults which can be removed from the remaining pieces of equipment in the lot. If t <m pieces of equipment are tested, then those that remain, mt = m  t, have reduced fault incidence and are more reliable than initially, but mt may be too small to be useful, or than is desirable. In this paper models are studied to address this question: given the lot size m, how to optimize by choice of t the effectiveness of the pieces of equipment remaining after the test The models used are simplistic and illustrative; they can be straightforwardly improved
