The evaluation of a possible future Sino-Japanese armed conflict through the application of the ACEI-model

There is relatively little formal modeling of the economic effects of armed conflicts even though they have substantial economic effects. We set forth a new model, namely the armed conflict economic impact model – ACEI-Model. The model looks at the economic effects of war in three different stages: (i) pre-conflict stage; (ii) armed conflict stage; and (iii) post-conflict stage. The model is based on economic desgrowth (-δ) and other new conceptual indicators. We evaluate an imaginary armed conflict between China and Japan by applying the ACEI-Model.     

Military and Veterans’ Health,Health Care,and Wellbeing

Abstract

The U.S. Department of Defense (DoD) and the U.S. Department of Veterans Affairs (VA) need to bridge a gap in their understanding of service members’ health outcomes and the issues involved in treatment, such as cost. In addition, clinicians and policy analysts must overcome existing knowledge barriers. Clinicians need to be aware of policy changes that will affect their patient load in numbers and in treatment needs. Policy analysts need to be aware of issues relevant to clinical treatment, such as quality and timeliness of care. Given the need for services and support to military personnel and families, and the fact that the fastest growing expenses in defense are health care costs, a multi-disciplinary line of research will help lawmakers understand the most efficient and effective resource use across the health care services.     

Interactive optimization methodology for fleet scheduling

This article addresses the problem of scheduling the United States Navy's Atlantic Fleet to satisfy overseas strategic requirements. An integer programming formulation is developed but results in a model with prohibitive size. This fact and the qualitative nature of additional secondary objectives and constraints suggest an interactive optimization approach. A system that solves a natural relaxation of the integer program within an interactive environment is discussed.

On compounded bivariate poisson distributions

A unified treatment is given for a class of discrete distributions derived by compounding a bivariate Poisson with a bivariate discrete or continuous distribution. Using generating functions a number of interesting results are obtained for probabilities, moments, cumulants, factorial moments, and factorial cumulants. Conditional distributions and regression functions are also examined. Five illustrative examples are presented in detail. © 1994 John Wiley & Sons, Inc.     

Optimum simple step-stress accelerated life tests for weibull distribution and type I censoring

This article presents an optimum simple step-stress accelerated life test for the Weibull distribution under Type I censoring. It is assumed that a log-linear relationship exists between the Weibull scale parameter and the (possibly transformed) stress and that a certain cumulative exposure model for the effect of changing stress holds. The optimum plan—low stress and stress change time—is obtained, which minimizes the asymptotic variance of the maximum likelihood estimator of a stated percentile at design stress. For selected values of the design parameters, nomographs useful for finding the optimum plan are given, and the effects of errors in preestimates of the parameters are investigated. As an alternative to the simple step-stress test, a three-level compromise plan is proposed, and its performance is studied and compared with that of the optimum simple step-stress test. © 1993 John Wiley & Sons.

Parallel machine scheduling: A probabilistic analysis

The minimum makespan of the general parallel machine scheduling problem with m machines and n jobs is studied. As for a number of other important combinatorial problems, the theory of empirical processes proves to be a very elegant and powerful tool for the probabilistic analysis of the solution value. It is used in this paper to derive a scheduling constant θ such that, for random processing times, the minimum makespan almost surely grows as θn when n goes to infinity. Moreover, a thorough probabilistic analysis is performed on the difference between the minimum makespan and θn. Explicit expressions for the scheduling constant are given for an arbitrary number of unrelated machines with identically distributed processing times (with an increasing failure rate), and for an arbitrary number of uniform machines and generally distributed processing times. © 1996 John Wiley & Sons, Inc.     

On the bivariate negative binomial distribution of mitchell and paulson

The bivariate negative binomial distribution of Mitchell and Paulson [17] for the case b = c = 0 is shown to be equivalent to the accident proneness model of Edwards and Gurland [4] and Subrahmaniam [19,20]. The diagonal series expansion of its joint probability function is then derived. Two other formulations of this distribution are also considered: (i) as a mixture model, which showed how it arises as the discrete analogue to the Wicksell-Kibble bivariate gamma distribution, and (ii) as a consequence of the linear birth-and-death process with immigration.
