Quality attributes energy costs

There are many characteristics that are desirable in a scintillator, including high scintillation efficiency, short decay time, linear dependence of the amount of light generated from deposited energy, good optical quality, and availability in large sizes at modest cost. No known material meets all these criteria, and therefore many different materials are in common use, each with attributes that are best suited for certain applications. 

A study determined that customers typically do not make buying decisions on their own but take the advice of relatives, friends, and particularly the sales force who exercise a strong influence in approximately half the sales decisions irrespective of product price. The first step is to determine key parameters of interest for a particular product. Consider, for example, audio equipment. From a table (similar to Table 3), selected are the top three or four attributes (e.g., price, cost of ownership, reliability, quality) mentioned most frequently. These selections represent the best candidates to link with environmental attributes to enhance the marketing value of an audio product. Similarly, the environmental factors were ranked by customers as listed in Table 4. Based on the results, it was concluded that energy consumption, hazardous substances, materials application, and recyclability were the most important environmental aspects to couple with other product attributes to help differentiate them from competitor products and increase their marketability [llj.
