Abstract
The practical problem of getting computational
work done at the lowest cost subject to certain specifications
interests many people. This paper
presents a decision model which will enable them
to choose, from among the alternatives available, the
combination of computing equipment that minimizes
computing costs for a given amount and
composition of work. This model, together with
other considerations, can provide a systematic basis
for selecting a machine complex for a data processing
installation. The model is useful also in
deciding whether to change a machine complex as a
result of changes in the workload or the availability
of improved equipment. The authors are indebted
to Lee M. Day and Burton French of Farm Production
Economics Division, Economic Research Service,
for helpful suggestions in the preparation of this
paper.
