This paper investigates the potential for modeling and simulation to contribute to new defense system development, by increasing the productivity of traditional R&D in developing system‐specific technology. Building on a previous optimal control model of defense system R&D, it shows that (1) the optimal use of modeling is related in a natural way to that of traditional R&D, and (2) both have similar optimal profiles over time. Simulated results based on limited historical data suggest that optimal use of modeling could increase the rate of growth in system‐specific technology significantly.  相似文献

Investments in R&D constitute a major share of the expenditures of the hi-tech industry since, generally, they enable firms to successfully compete in the rapidly and constantly changing markets for hi-tech products and services. The role of R&D projects is particularly important in the areas of defense and homeland security due to the nature of warfare and the continuous threats posed by arms races and by terror organizations. This study analyzes the choice of the R&D projects designed to counter multiple related military threats. It develops the methodology required to assess whether it is preferable to develop one project to thwart several related threats, or several distinct projects, each of which provides an answer to one specific threat or a partial set of the threats. An analytic solution is provided and assessed for two simple models with two related threats. A solution of the model is then provided for any number of related threats, using a dynamic programming methodology. Finally, we demonstrate the usefulness of our model and methodology to Israel’s missile defense problem; that is, we show how to optimally develop systems aimed at thwarting the multiple threats of short-, medium-, and long-range missiles.  相似文献

The paper presents an analysis of the factors explaining the export performance of firms in the defence sector. We focus on the case of Norway, and make use of two complementary methodologies: the first is based on econometric firm-level data analysis for the whole population of defence companies, and the second is based on qualitative case study research on the three most important defence export products (weapon stations, ammunition and electronics). Our empirical results highlight the importance of four major success factors for exporting firms: (1) the participation in offset agreements; (2) the ability to focus on their set of core competencies; (3) their R&D activities and interactions with the public S&T system; and (4) demand opportunities and, relatedly, user-producer interactions.  相似文献

The impact of defence expenditure on the economy has been widely studied through different types of models. However, the results from these studies have not reached definitive conclusions, and have left a gap in the analysis of the impact of defence R&D expenditure at the economy level. Defence R&D has specific characteristics, which lead to market failures: public good, high risk and uncertainty, national security. Also, defence R&D creates two types of externalities: negative (crowding-out), and positive (spin-off). Crowding-out is the major economic debate about defence R&D. This paper analyses the crowding-out hypothesis by applying three types of models for the UK case: supply, demand, and demand-supply models. From these three models the most reliable is chosen and applied to the individual cases of France, Germany, Japan and USA. The paper also reports the results for the pooled data of these five countries, and for four error component models. The results from estimating such models shed light on the defence R&D crowding-out hypothesis.  相似文献

In recent years, there have been several changes in the weapon‐system acquisition market which have the potential to negatively impact the financial condition of defense contractors. This study evaluates the financial health of defense firms vis‐a‐vis nondefense firms using a fiscal distress identification model developed by E.I. Altman. We conclude that the financial condition of defense firms has deteriorated but the deterioration is the same as experienced by nondefense firms.  相似文献

This article surveys the body of available evidence regarding the spill-over effects of defence R&D. It reviews the routes through which defence R&D spills over to the economy with positive externalities – in terms of new products, technologies or processes; the barriers that impede or block such a process; potential negative repercussions, and the measure of such effects. The main conclusion is that the uncertainty of these effects, and the inaccurate appraisal of their value, hardly supports informed decisions concerning defence R&D policies.  相似文献

This paper models the determination of the defence industrial base – the number of different military systems a country decides to maintain. High R&D costs means that few countries can afford to produce major weapons systems and the producers also import systems. Non‐producers rely on imports and we assume their demand is driven by regional arms races. Military capability is determined by the number of systems and the quantity and quality of each. We examine how the defence industrial base is influenced by military expenditures, R&D costs, export controls, the nature of regional arms races and a variety of other factors.  相似文献

As we enter the 21st Century, technologies originally developed for defense purposes such as computers and satellite communications appear to have become a driving force behind economic growth in the United States. Paradoxically, almost all previous econometric models suggest that the largely defense‐oriented federal industrial R&;D funding that helped create these technologies had no discernible effect on U.S. industrial productivity growth. This paper addresses this paradox by stressing that defense procurement as well as federal R&;D expenditures were targeted to a few narrowly defined manufacturing sub‐sectors that produced high tech weaponry. Analysis employing data from the NBER Manufacturing Productivity Database and the BEA’ s Input Output tables then demonstrates that defense procurement policies did have significant effects on the productivity performance of disaggregated manufacturing industries because of a process of procurement‐driven technological change.  相似文献

From the early 1980s Spain embarked on a wide‐ranging process of military reform, from organisational changes to defence industrial policies. Investment in military equipment was set to grow, policies were drawn up to foster the domestic defence industrial base, defence R&D rocketed, and Spain joined a myriad of international arms development programmes. Yet, by 1991 the process of reform had run out of steam. Expenditure planning proved unreliable, and firms suffered from sharp cutbacks in procurement expenditure. The model of defence industrial growth sketched in the mid‐1980s had floundered. The Spanish case provides an example of how the quest to maximise defence procurement from domestic sources can fall victim to industrial and budgetary constraints. Spanish defence producers are now becoming increasingly intertwined with foreign defence companies.  相似文献

Central to the changes in UK Ministry of Defence procurement policies over recent years has been the attempt to shift risk out of the public sector. In the context of research and development this has taken the form of encouraging private venture investment, so‐called PVR&D. Recognising that the scope for PVR&D is necessarily constrained by excessive risk and imperfect information, this paper explores the possible use of Option contracts as a means of expanding the opportunities for private venture funding.  相似文献

Defense industrial complexes in leading Cold War nations have downsized and reallocated resources to other productive activities in the 1990s. In this paper, we analyze the experience of two key countries ‐ the US and France. Comparing the two countries, we find similar outcomes in budgetary retrenchment and large firm restructuring but marked differences in the pace of downsizing and diversification among small and medium‐sized firms. We hypothesize that three sets of contextual differences may explain these differences: 1) institutional differences in the way that the State bureaucracies ‐ the Pentagon and the French Délégation générale pour l'armement (DGA) ‐ oversee defense industrial matters, 2) differences in military industry ownership and firm size patterns, and 3) differences in the regional distribution of defense industrial capacity and associated regional policies. In closing, we note that the two countries’ defense industrial complexes are becoming more alike and speculate on the significance of invidious competition and interactions between them. We address briefly the future of French/American arms industrial competition and cooperation, given the trend towards transnational security arrangements and defense industry globalization  相似文献

We explore the efficacy of counterespionage measures in the realm of Economic Espionage. Although it is possible that increasing counterespionage measures has the desired effect of increasing domestic research and development (R&D) and reducing espionage by foreign entities, it is also possible that these increased measures actually do just the opposite: domestic R&D suffers and foreign stealing increases. We identify the appropriate settings for increased counterespionage measures and provide some policy advice.  相似文献

The electronics industry provides components and capabilities that are critical to modern defence requirements. It is anticipated that the effectiveness of both weapons systems and the command and control network that supports military operations will become increasingly dependent upon the electronics sub‐systems they employ in the future. With the ascendancy of ‘network centric warfare’, it seems certain that defence electronics will continue to grow in importance in the future, enabling far‐reaching advances in military capability and efficiency. Yet little is known about the structure, conduct, performance and competitiveness of the UK defence electronics sector as it prepares to meet the challenges ahead. This paper reports the findings of a study commissioned in 2002 by Intellect, the UK defence electronics trade association, and supported by the Department of Trade and Industry. The UK defence electronics industry is found to be a high technology, R&D‐intensive and decreasing cost industry, which is competitive in world defence markets. The UK industry faces major competitive threats in the future from established US and European firms and from potential new entrants from China, India, Israel, Singapore, South Korea and Turkey. The future competitiveness of the UK defence electronics industry will depend on maintaining both technical advantage and open access to the large US market.  相似文献

This paper explores whether defense contractors' manufacturing technology advantages over purely commercial firms might be associated with differences in their workforce and organizational practices. It uses unique original data collected specifically to test workforce and organizational complementarities in implementation of advanced manufacturing technology in small manufacturers. Findings are that defense contractors: (1) have higher and deeper rates of advanced manufacturing technology use; (2) have greater perceived success in achieving manufacturing goals; (3) are more likely practitioners across a diverse spectrum of advanced workforce and organizational practices. Then, (4) econometrically, the defense contractors' higher reported levels of achievement in implementing advanced manufacturing technologies are positively associated with those organizational and workforce practice differences.  相似文献

Countries with a federalist system of government have different arrangements for providing national security. US national security is provided by national and State defense forces. The quintessential national function – national defense – experienced some changes that enhanced the role of the States. Policy changes in the National Defense Authorization Act of 2008 (2008 NDAA) introduced new roles for the Governors and the State defense forces, or the National Guard. This article explores how the interests of Congress and States aligned in the 2008 NDAA such that the national defense function changed. This article finds that the national government continues to have the central coordinating role, but that the politics and provisions of the 2008 NDAA changed the national–State relationship in mission, decision-making, and command and control so that US federalism in the national defense function is evolving in unexpected ways.  相似文献

A mathematical formulation of an optimization model designed to select projects for inclusion in an R&D portfolio, subject to a wide variety of constraints (e.g., capital, headcount, strategic intent, etc.), is presented. The model is similar to others that have previously appeared in the literature and is in the form of a mixed integer programming (MIP) problem known as the multidimensional knapsack problem. Exact solution of such problems is generally difficult, but can be accomplished in reasonable time using specialized algorithms. The main contribution of this paper is an examination of two important issues related to formulation of project selection models such as the one presented here. If partial funding and implementation of projects is allowed, the resulting formulation is a linear programming (LP) problem which can be solved quite easily. Several plausible assumptions about how partial funding impacts project value are presented. In general, our examples suggest that the problem might best be formulated as a nonlinear programming (NLP) problem, but that there is a need for further research to determine an appropriate expression for the value of a partially funded project. In light of that gap in the current body of knowledge and for practical reasons, the LP relaxation of this model is preferred. The LP relaxation can be implemented in a spreadsheet (even for relatively large problems) and gives reasonable results when applied to a test problem based on GM's R&D project selection process. There has been much discussion in the literature on the topic of assigning a quantitative measure of value to each project. Although many alternatives are suggested, no one way is universally accepted as the preferred way. There does seem to be general agreement that all of the proposed methods are subject to considerable uncertainty. A systematic way to examine the sensitivity of project selection decisions to variations in the measure of value is developed. It is shown that the solution for the illustrative problem is reasonably robust to rather large variations in the measure of value. We cannot, however, conclude that this would be the case in general. © 2001 John Wiley & Sons, Inc. Naval Research Logistics 48: 18–40, 2001  相似文献
