Computer application development is an area of explosive growth, providing dramatic new capabilities to do additional work faster and more accurately. In the construction industry, computer aided design and drafting (CADD) systems make it possible to more completely specify work to be done. Some project owners require drawings be submitted in magnetic form. Therefore, it is necessary for construction and engineering firms to acquire and develop expertise in state of the art computer systems. Because many system configurations are available, selection of CADD systems is an important decision, requiring consideration of a number of objectives. AHP is used to combine cost factors with subjective factors. AHP also is used to consider the impact on end users as a group and an central data processing.
