Optimizing quality levels and development costs for developing an integrated information security system

초록

Increased Internet threats make many kinds of information security systems performing various functions, which can often be combined into functions of an integrated information security system. To load various functions to an integration information system, much development resources should be invested to a development life cycles. The constraints of development resources force developers not to achieve a balanced quality of the system. To attain the specified quality of the system within the given development resources, the relative weights among quality factors of the system on a development life cycle should be measured and a balance between the levels of quality and development costs should be optimized, simultaneously. This paper suggests the relative weights of the quality factors influencing operations of the system, and shows an optimal solution for the quality levels and development costs using desirability function (DF). For optimization, this paper employs AHP as multiple criteria decision making (MCDM) technique and DF.
