Morale and Battlefield Performance at Caporetto, 1917

Abstract

How does morale relate to tactical and operational failure? Is it a cause or an effect? Using the Italian Army at Caporetto as a case study, this article explores the cyclical relationship between battlefield performance and morale. Combining quantitative analysis of army statistics with qualitative analysis of various official and private sources, this article analyses morale before the battle and during its opening phase. Italian morale appears surprisingly resilient and decisions to surrender or desert frequently relied on objective assessment of events rather than demoralisation. In this case it was battlefield defeat which turned disaffection into a full- scale morale crisis.     

Heuristics for the multi‐resource generalized assignment problem

The well‐known generalized assignment problem (GAP) involves the identification of a minimum‐cost assignment of tasks to agents when each agent is constrained by a resource in limited supply. The multi‐resource generalized assignment problem (MRGAP) is the generalization of the GAP in which there are a number of different potentially constraining resources associated with each agent. This paper explores heuristic procedures for the MRGAP. We first define a three‐phase heuristic which seeks to construct a feasible solution to MRGAP and then systematically attempts to improve the solution. We then propose a modification of the heuristic for the MRGAP defined previously by Gavish and Pirkul. The third procedure is a hybrid heuristic that combines the first two heuristics, thus capturing their relative strengths. We discuss extensive computational experience with the heuristics. The hybrid procedure is seen to be extremely effective in solving MRGAPs, generating feasible solutions to more than 99% of the test problems and consistently producing near‐optimal solutions. © 2001 John Wiley & Sons, Inc.
