Process Optimization and Profitability Calculations

Abstract
Beginning with a typical example of cost control, key parameters are suggested in order to judge the effect of optimization efforts on costs. Each optimization process automatically has some effect on productivity and production figures; however, the safety factor – expressed in terms of shading and redyeing operations – must not be left out of consideration. The influence of these factors on the costs as well as on the production figures is shown. By means of these factors the dyeing processes optimized for the machines used up to now are compared with the processes for new machines (high performance) as far as costs are concerned. The prerequisites which must be satisfied when optimizing dyeing processes in order to achieve low costs are emphasized. Furthermore, non‐optimized processes on existing machines are compared with the so‐called rapid‐dyeing processes.
