Table 9.12 Some major deterministic operational research techniques
applicable in marketing (the methods, advantages, limitations and when
recommended to use)
Method Based on Marketing
applications
Main advantages Major limitations
Linear
programming
Objective and
constraint linear
functions
(a) Advertising
(Higgins, 1973),
space, optimal
media mix
allocations
(b) Distribution
problems, site
location
(Kotler, 1972)
(c) Budget
allocation, new
product
decision
(Wilson, 1975)
(d) Blending
product mixes
(e) Marketing mix
decisions
(a) Maximizes
profitability of
allocations,
subject to
constraints
(b) Minimizes costs
(c) Aids
management in
decision
making
(a) Difficult to
obtain and
formulate the
various
functions
(b) Constraints
must be
altered as soon
as external
and/or internal
factors change
Transportation
model
Transportation/
allocation matrix
ascertaining the
minimum costs,
routes, quantities
supplied, etc.
To allocate
resources, supply
etc. by reducing
transportation
costs. Suitable
particularly for
department stores,
truck rental firms,
transport
companies
Very suitable for
managerial decision
making
Inaccurate in the
longer run as a
result of changes in
costs
Non-linear
programming
Non-linear
objective functions
and non-linear
constraint
relationships
To find the
maximum return
to a new product
search, subject to
budget constraint
(a) When the
relationships
are non-linear
(b) When the
objective
function is
non-linear
while the
constraints are
non-linear
Difficult to
establish non-linear
relationships
