OPTIMAL RELEASE PROBLEM BASED ON THE NUMBER OF DEBUGGINGS WITH SOFTWARE SAFETY MODEL

摘要

In this paper, we discuss the optimal software release problem based on the number of debuggings, using the Markovian software safety model. First, we formulate the total expected software cost occurring in the testing phase and the warranty period after release and discuss the optimal software release problem based on the cost criterion. Furthermore, we treat the problem considering both cost and safety requirement simultaneously. We investigate the optimal software release policies for the problems. Finally, we present several numerical examples of the policies.
