In the 1970’s John Gittins discovered thatmulti-armed bandits, an important class of models for the dynamic allocation of a single key resource among a set of competing projects, have optimal solutions ofindexform. At each decision epoch such policies allocate the resource to whichever project has the largestGittins index. Since the 1970’s, Gittins’ index result together with a range of developments and reformulations of it have constituted an influential stream of ideas and results contributing to research into the scheduling of stochastic objects. We give a brief account of many of the most important contributions to this work and proceed to describe how index theory has recently been developed to produce strongly performing heuristic policies for the dynamic allocation of a divisible resource to a collection of stochastic projects (orbandits). A limitation on this work concerns the need for the structural requirement ofindexabilitywhich is notoriously difficult to establish. We introduce a general framework for the development of index policies for dynamic resource allocation which circumvents this difficulty. We utilise this framework to generate index policies for two model classes of independent interest. Their performance is evaluated in an extensive numerical study.
