Skeptics of the Bush administration have castigated its strong aversion to formal international agreements in responding to the threat of the proliferation of weapons of mass destruction (WMD), citing unilateral actions as the default alternative. Yet this critique misses the growing emergence of a conscious framework guiding the administration's actions: an emphasis on the exercise of national sovereignty and the corollary principle of sovereign responsibility. Rejecting the paradigm of arms control as the answer to WMD proliferation, the current administration instead advocates a toolkit of alternative mechanisms based on the full exercise by individual nation, states of their domestic authorities and rights under international law, acting in their capacities as responsible citizens of the global community. This paper will examine that philosophical approach and its concrete application through the following policies: (1) the Proliferation Security Initiative; (2) enforcement of national laws and regulations as exemplified by United Nations Security Council Resolution 1540 and the U.S. proposals for consideration by Biological Weapons Convention signatories; and (3) preemptive warfare to disarm the WMD programs of a threatening state. 相似文献

Building on prior work on optimal replacement of aging aircraft, this paper presents three methodologies to evaluate prospective aviation Service Life Extension Programs (SLEPs) and applies these methodologies to US Navy F/A-18E/F data. While considerable uncertainty remains as to the values of key parameters (e.g. the cost of F/A-18E/F SLEPs), the preponderance of the evidence available at this juncture favors undertaking SLEPs on F/A-18E/Fs rather than replacing them with new Joint Strike Fighters. 相似文献

We introduce a formulation and an exact solution method for a nonpreemptive resource constrained project scheduling problem in which the duration/cost of an activity is determined by the mode selection and the duration reduction (crashing) within the mode. This problem is a natural combination of the time/cost tradeoff problem and the resource constrained project scheduling problem. It involves the determination, for each activity, of its resource requirements, the extent of crashing, and its start time so that the total project cost is minimized. We present a branch and bound procedure and report computational results with a set of 160 problems. Computational results demonstrate the effectiveness of our procedure. © 2001 John Wiley & Sons, Inc. Naval Research Logistics 48: 107–127, 2001 相似文献

We consider a class of partitioning problems where the partitioned set is a finite set of real numbers and the objective function of a partition is a function of the vector whose coordinates are the sums of the elements in each part of the given partition (the number of such parts is assumed given). We obtain an explicit solution of such partitioning problem with polynomial complexity bounds. © John Wiley & Sons, Inc. Naval Research Logistics 47: 531–540, 2000 相似文献
