Study of the Warranty Cost Model for Software Reliability with an Imperfect Debugging Phenomenon

摘要

Software reliability is one of the most importantcharacteristics of software quality. Its measurement and managementtechnologies employed during the software life-cycle are essential forproducing and maintaining quality/reliable software systems. Herein,we discuss a modified approach to calculating the delivery cost of asoftware product, when warranty is to be provided, with an imperfectdebugging phenomenon. Unlike existing cost models, here the strategywas to consider maintenance support given to the customer with animperfect debugging phenomenon. The optimal release time can becalculated for various reliability levels by minimizing the cost. Thedelivery cost, reliability of the software system, and the optimalrelease time were calculated by using an imperfect debugging softwarereliability growth model. Numerical illustration supports the optimalrelease policies
