空袭与防空作战的对策分析

假设在局部(常规)战争情况下,攻方要使用轰炸机袭击守方的要地(政治经济中心,交通枢纽等),守方使用高射炮、地空导弹和歼击机进行抗击。双方都知道对方的兵力部署情况(数量和位置)。攻方作为主动作战的一方具有主动权,出动多少兵力袭击何种目标,守方事先是不知道的。但是当攻方飞机出动后守方便可知道其用兵的意图。攻方的最终目的是要炸毁守方的要地。为了达到预期的突击效果而又尽量减少损失,采取如下的作战方针:先出动部分兵力去袭击守方的防空体系,如机场、雷达站和高炮地导阵地,我们称之为第一波次;在守方还来不及处理由于轰炸而造成的后果时(即所谓利用第一波次的突击效果),再出动其余兵力去突击要地,我们称之为第二波次。

Multilayers in a modulated stochastic game

We are concerned with an antagonistic stochastic game between two players A and B which finds applications in economics and warfare. The actions of the players are manifested by a series of strikes of random magnitudes at random times exerted by each player against his opponent. Each of the assaults inflicts a random damage to enemy's vital areas. In contrast with traditional games, in our setting, each player can endure multiple strikes before perishing. Predicting the ruin time (exit) of player A, along with the total amount of casualties to both players at the exit is a main objective of this work. In contrast to the time sensitive analysis (earlier developed to refine the information on the game) we insert auxiliary control levels, which both players will cross in due game before the ruin of A. This gives A (and also B) an additional opportunity to reevaluate his strategy and change the course of the game. We formalize such a game and also allow the real time information about the game to be randomly delayed. The delayed exit time, cumulative casualties to both players, and prior crossings are all obtained in a closed-form joint functional.     

Random Walk Analysis in Antagonistic Stochastic Games

Abstract

This article deals with two “antagonistic random processes” that are intended to model classes of completely noncooperative games occurring in economics, engineering, natural sciences, and warfare. In terms of game theory, these processes can represent two players with opposite interests. The actions of the players are manifested by a series of strikes of random magnitudes imposed onto the opposite side and rendered at random times. Each of the assaults is aimed to inflict damage to vital areas. In contrast with some strictly antagonistic games where a game ends with one single successful hit, in the current setting, each side (player) can endure multiple strikes before perishing. Each player has a fixed cumulative threshold of tolerance which represents how much damage he can endure before succumbing. Each player will try to defeat the adversary at his earliest opportunity, and the time when one of them collapses is referred to as the “ruin time”. We predict the ruin time of each player, and the cumulative status of all related components for each player at ruin time. The actions of each player are formalized by a marked point process representing (an economic) status of each opponent at any given moment of time. Their marks are assumed to be weakly monotone, which means that each opposite side accumulates damages, but does not have the ability to recover. We render a time-sensitive analysis of a bivariate continuous time parameter process representing the status of each player at any given time and at the ruin time and obtain explicit formulas for related functionals.

Deterministic economic production quantity models with time-varying demand and cost

In today’s time-based competition, the unit cost of a high-tech product declines significantly over its short product life cycle. Consequently, in this paper, we relax the traditional economic production quantity model to allow for time-varying cost. We then prove that the optimal production schedule uniquely exists. In addition, we also show that the total cost is a convex function of the number of replenishments, which reduces the search for the optimal solution to finding a local minimum. Furthermore, we characterize the influences of both demand and cost over the length of production run time and the economic production quantity.

On studentized non-parametric multi-sample location tests

Summary The usual non-parametric multi-sample location tests are based on the assumed identity of the scale parameters of the different cumulative distribution functions (cdf’s). Here is considered the problem of testing the homogeneity of the location parameters without assuming the identity of the corresponding scale parameters. Such a test appears to be very rare in the literature on non-parametric location tests, and the necessary modifications with a class of tests based on certain U-statistics and order statistics, have been discussed here. This paper was read before the Statistics Section of the 48th Indian Science Congress Session held at Roorkee, 1961.     

管理者过度自信对高技术企业技术外部获取方式选择的影响研究

企业管理者的业绩预测偏差是衡量管理者是否过度自信的一个重要体现,值得关注和研究。本研究采用我国2004~2013年高技术上市公司的相关数据,应用Ordered-probit模型实证分析了管理者过度自信对高技术上市公司技术外部获取方式选择的影响。研究结果表明:我国高技术上市公司以非股权技术联盟作为首要的技术外部获取方式,公司风险投资是最后的选择;同时,研究发现:在对技术外部获取方式进行选择时,管理者过度自信的高技术上市公司选择并购优先于合资和少数持股联盟,而管理者非过度自信的高技术上市公司选择少数持股联盟优先于并购和合资。该研究方法简单、高效、合理,是企业高管提升公司管理水平和科学获取技术外部的一种新的方法选择。
