Economic ordering decisions with market choice flexibility

Standard approaches to classical inventory control problems treat satisfying a predefined demand level as a constraint. In many practical contexts, however, total demand is comprised of separate demands from different markets or customers. It is not always clear that constraining a producer to satisfy all markets is an optimal approach. Since the inventory‐related cost of an item depends on total demand volume, no clear method exists for determining a market's profitability a priori, based simply on per unit revenue and cost. Moreover, capacity constraints often limit a producer's ability to meet all demands. This paper presents models to address economic ordering decisions when a producer can choose whether to satisfy multiple markets. These models result in a set of nonlinear binary integer programming problems that, in the uncapacitated case, lend themselves to efficient solution due to their special structure. The capacitated versions can be cast as nonlinear knapsack problems, for which we propose a heuristic solution approach that is asymptotically optimal in the number of markets. The models generalize the classical EOQ and EPQ problems and lead to interesting optimization problems with intuitively appealing solution properties and interesting implications for inventory and pricing management. © 2003 Wiley Periodicals, Inc.

Privatizing the struggle against Somali piracy

Pirate attacks against commercial vessels in the Western Indian Ocean and nearby seas reached an unprecedented level in 2011. Despite concerted efforts by the international community and shipping companies to address this threat by conducting naval patrols and equipping commercial vessels with non-lethal defenses, the frequency of pirate attacks continues to increase. The general ineffectiveness of existing anti-piracy measures has sparked interest in expanding the use of armed private security contractors to protect commercial vessels from pirate attacks. This article argues that armed private security contractors can, indeed, enhance the security of commercial vessels because these actors can provide onsite protection for commercial vessels, which should allow them to respond very quickly to pirate attacks, and because these actors are willing to use deadly force against pirates. However, this article also argues that expanding the use of these actors may increase the degree of violence used during pirate attacks, pose threats to the safety of innocent civilians, and violate a number of domestic and international laws.     

Modeling the effects of military tension on foreign trade: Some preliminary empirical findings from the Greek-Turkish rivalry

In this paper we examine the effects of irreversibility on foreign trade in the case where there are two sources of uncertainty. The two sources considered in this paper are uncertainty arising from business risk and uncertainty arising from military tension. The resulting insights are then used to model the import markets of Greece and Turkey. These models are then empirically estimated, in order to ascertain, on the one hand whether there is evidence that irreversibility is indeed a factor on the supply side of these markets, and on the other hand, the direction of the incidence of military tension on foreign trade. An index of military tension is used for the two countries, based on the number of airspace violations by Turkish military aircraft of Greek airspace.     

Concise RLT forms of binary programs: A computational study of the quadratic knapsack problem

The reformulation‐linearization technique (RLT) is a methodology for constructing tight linear programming relaxations of mixed discrete problems. A key construct is the multiplication of “product factors” of the discrete variables with problem constraints to form polynomial restrictions, which are subsequently linearized. For special problem forms, the structure of these linearized constraints tends to suggest that certain classes may be more beneficial than others. We examine the usefulness of subsets of constraints for a family of 0–1 quadratic multidimensional knapsack programs and perform extensive computational tests on a classical special case known as the 0–1 quadratic knapsack problem. We consider RLT forms both with and without these inequalities, and their comparisons with linearizations derived from published methods. Interestingly, the computational results depend in part upon the commercial software used. © 2009 Wiley Periodicals, Inc. Naval Research Logistics, 2010     

Country survey V: Poland and its arms industry

This study — which is a country survey — deals with basic problems of the functioning of the Polish arms industry in the conditions of systemic transformation, that has taken place in Poland since 1989. It also reflects new political and military conditions and changes in the economic system, commonly called marketization. The study is focused on reasons for the bad economic state of the enterprises engaged in military production, which include a drastic drop in demand on home and foreign markets. The study discusses the main direction of activities that are planned to reshape and adjust military production to the new, changed conditions covering such problems as ownership and organization changes as well as prospects for conversion.

The transshipment fund mechanism: Coordinating the decentralized multilocation transshipment problem

The multilocation replenishment and transshipment problem is concerned with several retailers facing random demand for the same item at distinct markets, that may use transshipments to eliminate excess inventory/shortages after demand realization. When the system is decentralized so that each retailer operates to maximize their own profit, there are incentive problems that prevent coordination. These problems arise even with two retailers who may pay each other for transshipped units. We propose a new mechanism based on a transshipment fund, which is the first to coordinate the system, in a fully noncooperative setting, for all instances of two retailers as well as all instances of any number of retailers. Moreover, our mechanism strongly coordinates the system, i.e., achieves coordination as the unique equilibrium. The computation and information requirements of this mechanism are realistic and relatively modest. We also present necessary and sufficient conditions for coordination and prove they are always satisfied with our mechanism. Numerical examples illustrate some of the properties underlying this mechanism for two retailers. © 2010 Wiley Periodicals, Inc. Naval Research Logistics, 2010
