We present a time decomposition for inventory routing problems. The methodology is based on valuing inventory with a concave piecewise linear function and then combining solutions to single‐period subproblems using dynamic programming techniques. Computational experiments show that the resulting value function accurately captures the inventory's value, and solving the multiperiod problem as a sequence of single‐period subproblems drastically decreases computational time without sacrificing solution quality. © 2010 Wiley Periodicals, Inc.

From the beginning of history, war has been an almost exclusively male affair and those who took part in it were often extolled as the most manliest of men. The recent feminization of the armed forces of many developed countries does not prove that women's liberation is making progress, as most people believe. Rather, it is part symptom, part cause, of the decline of those forces. Other things being equal, the fewer and less important the wars fought by any armed force the more women it has; the more women it has, the less likely it is to undertake serious wars. 相似文献

This brief introduction celebrates the 20th Anniversary of the Journal, Defence and Peace Economics. Suggesting elements of an agenda for the future of this branch of economics, I raise several topics that are new and that seem to indicate that the field will expand and shift focus substantially in future years. 相似文献
