Production theory and the theory of cost both belong to the central
areas of business administration, for all considerations concerning the
economic organization of industrial manufacturing processes start from
these. Two developments in the past 30 years have had a considerable
influence on the structure and the concentration on points of emphasis
in this book. I am referring to findings from KOOPMANS' activity
analysis and to the formulation by GUTENBERG of a production function
concept that focuses on industrial production processes. Activity
analysis has made it possible to develop, from a uniform approach,
different types of production functions which describe the concrete
principles of production in the productive sector of a business
enterprise; this has created a common basis for all production concepts
in business administration. The Gutenberg Production Function with its
different kinds of adjustment to a changing output has opened up a
flexibility to theoretical and practical considerations that gave rise
to a large number of additional studies in this area. Considerations in
cost theory were in particular need of considerable extensions in the
direction of cost minimal combined adjustment processes. By means of the
organization of its contents, this book will take both approaches into
due account. In that way, it is vastly different from other books
dealing with the same subject. As a matter of course, traditional
analytical methods and ways of thinking also constitute a large part of
the book.
