Information Production Functions in Dynamic Lot-Sizing

Abstract

The complex problem of describing procedures of information processing in PPC-systems in the manner of activity analysis was discussed in detail by FANDEL (1991 and 1992). In this context notions like information processing activity and information technology had to be defined and several definitions of efficiency and dominance had to be stated. This was done in order to define information about goods, which are involved in the production of a company, as input and output goods of production planning and control and to describe formally procedures of efficient information processing in PPC-systems by information production functions. After all; these considerations serve to evaluate individual PPC-methods, -modules or total PPC-systems on the basis of efficient and dominant procedures of information processing. This is so as the planning procedure for solving a PPC-task or the whole complex of tasks is certainly superior to another procedure, if it achieves better results in the sense of a certain dominance definition when using and generating relevant information for the mastering of such planning tasks.
