Operations research aims to assist managers faced with problems of
coordinating activities; improving the quality of care of services
delivered; making optimal resource allocation decisions and generally,
managing services and institutions. Operations research (or O.R.) was
originally developed in response to the problems of the second World
War. It was characterised then by a unifying and clear objective; clear
problems that had to be solved and the use of inter-disciplinary teams
to analyse and solve identified problems. This analysis often drew on
mathematical techniques. After the war, operations research moved in two
separate but related directions. In England, the emphasis on
inter-disciplinary approaches and problem solving teams remained. The
operations researcher still used mathematical techniques but these were
not systematised into a volume of standard formulae. The emphasis of
operations research was on the approach not the tools used (see, for
example, Luckman & Stringer, 1974; also Luck, Luckman, Smith & Stringer
1971; and McLachlan, 1975). In the United States, the emphasis was
placed on the use of mathematical techniques. Operations research became
a mathematically based science relying on standardised models (e. g.
queuing, allocation) and formulae. This approach was facilitated by the
availability of computers.
