Production control can be regarded as a sub-system of the tota1
production system. The development of system theory is a major step
forward in the study of organisation: Scott (1967)1 comments upon
the systems approach: "The distinctive qualities of modern organisation
theory are its conceptual-analytical base, its reliance on empirical
research data, and, above all, its synthesising, integrating, nature.
These qualities are framed in a philosophy which accepts the premise
that the only meaningfu1 way to study organisation is as a system."
Simon (1964)2 agrees with this view judging organisations as complex
systems of decision-making processes. The term "systems" being used
more and more to refer to methods of scientific analysis that are
particularly adapted to the unravelling of complexity. Homans (1950)3
considers an organisation as comprising an external environment system
and an internal system of relationship which are mutually
interdependent. In this context production control can be looked
upon as a linking system between the environment represented by
customer demaod and the production system seen as a conversion process
for transforming raw materials and bought out components into finished
goods to satisfy this demand.
