Applications
OR has had an enormous impact on the management of modern
organisations.
- LP has found extensive acceptance; an example of this is the
regular use in planning the operations of an Oil Refinery.
- Financial Modelling, a central tool of modern decision
processes, is often the domain of the OR practitioner.
- Queueing Theory is used to design various service facilities;
for instance, in Post Offices and banks we have over recent years found
ourselves directed into a multi-server single queue.
- Simulation has become a standard tool to assist in the design
of many facilities where the layout is too complex to be analysed by
analytical queueing theory.
Following is a selection of specific examples taken from proceedings
of ASOR National Conferences and Bulletins.
- The Shell co. of Australia
utilises a mixed integer linear
programme with special ordered sets of type 1 to take account of
quantity discounts when selecting tenders for the purchase of additives
for its range of lubricants.
- Telstra offers as a
service a model to determine the number of operators and incoming
circuits to meet practical delay and loss standards in an automatic Call
Distributor involving post-call activity for the operator. Such systems
are common in booking offices, public utilities and the TAB.
- BHP is developing a
new approach to the scheduling of ships by utilising artificial
intelligence and knowledge engineering techniques. This gives an
interactive system of great flexibility.
