DESIGNING A VIABLE PREDICTION MARKET TO FORECAST DEFENSE ACQUISITION COST AND SCHEDULE OUTCOMES

This paper is the first to demonstrate a viable prediction market that successfully forecasts defense acquisition cost and schedule outcomes, and to provide insights for defense executive decision‐making. Already used in private industry, prediction markets can also accurately forecast outcomes and their associated risks for government programs. Using virtual money, prediction markets allow traders to ‘bet’ on some future outcome. This market mechanism turns out to be a relatively simple and accurate way to discover, aggregate, and communicate to a defense executive the collective market’s beliefs about the likelihood of an eventual outcome of an acquisition program of interest.

装备采办中的讨价还价博弈模型

竞争性谈判是一种重要的武器装备采办方式,军方与承包商之间的谈判是一个重复博弈过程,双方谈判的本质是讨价还价。分析了轮流出价的讨价还价模型,对轮流出价博弈的子博弈精炼均衡进行了论述;在轮流出价模型的基础上建立了同时出价的讨价还价模型,并对2种模型的特点进行了分析;通过案例对2个模型的均衡结果进行了对比。分析结果显示：同时出价的讨价还价模型更能有效解决实际问题,更具有现实意义。     

Military Off the Shelf Procurements: A Norwegian Case Study

Buying off the shelf procurements (OTS) has become an important part of the national acquisition strategy in several countries, and this paper seeks to bring empirical evidence on OTS as the preferred acquisition strategy by use of data from 2015 to 2022 investment portfolio of the Norwegian Armed Forces. We develop definitions for three categories of procurement – OTS, modified OTS and development projects – as well as a method to classify projects into these categories. Our first finding is that the characteristics of OTS projects correspond to modified OTS and development projects. Our second finding indicates that OTS projects perform better when it comes to the completion of projects according to the initial schedule, compared to development projects.     

On Government-industry Nexus and Indigenous Armed Resistance

This paper proposes a simple game-theoretic framework for analyzing the relationship between the government, industry and indigenous community, especially in the context of mounting violence surrounding displacement of indigenous communities by governments for the purposes of commercial use of their habitat. It specifically takes into account the possibility of alleged ‘nexus’ between the government and the industry and explores its implications on the level of allocation and utilities of the players. We find that the bias in allocation that occurs when the government and the industry enter a ‘nexus’ can be rectified when there is resistance from the indigenous groups. Moreover, rebellion is a dominant strategy of the indigenous community, irrespective of whether there is ‘nexus’ or not, and being in ‘nexus’ with the government is a best response for the industry. The unique SPNE occurs when there is ‘nexus’ between the industry and the government and resistance by the indigenous groups, corroborating the widespread allegations of ‘nexus’ and evidence of resistance worldwide. We also explore a few extensions of the basic model and present some narrative evidence in support of the theoretical model.     

基于激励机制的装备采办风险总量控制

针对装备采办中的风险总量控制,提出一种激励方式来提高承包商的积极性。在单目标风险控制模型的基础上,建立了多目标风险控制模型,推导出了激励机制下风险控制的最优合同公式。对激励机制中存在的两类错误进行了理论分析和实例验证,得出了两类错误对收益的影响,并在成本控制中得到了应用,有效地提高了装备采办的质量和效率,为军方决策者在装备采办中提供了合理的参考依据。     

一种高速实时数据采集处理系统设计

针对目前高速数据采集中的实时性和同步性问题,提出了一种高速实时数据采集处理设计方案。根据上述方案进行了系统的硬件和软件设计,该系统以FPGA器件作为下位机控制核心,设计了时钟同步、数据采集、数据处理、数据缓存、数据通讯等功能模块;整个系统采用ARM微处理器作为上位机控制核心,基于嵌入式Linux 2.6内核进行软件编程,负责向FPGA发送设置参数和控制指令,同时对数据前端采样和处理数据进行存储、显示、统计等。经测试验证,该方案具有高速率、高精度、同步测量、实时处理、体积小、功耗低等优点。
