Cost justification methods for process control in the glass industry

Process control systems, as the result of high initial cost and impact on productivity and quality, require both effective and appropriate investment evaluation. Both quantitative methods and qualitative factors are discussed, with examples given of how they might be applied to a typical glass manufacturing project. Essential to any approach is the determination of project cost limitations prior to surveying available alternatives. Several effective methods of reducing scope and cost are also discussed from a design firm´s point of view.<>
