In allusion to the flaws in software cost model and optimal release policy, inadequate consideration for real debugging, a cost model and optimal release policy for SRGM (Software Reliability Growth Model) incorporating imperfect debugging is proposed. A SRGM is presented, based on incomplete debugging, introduction of new faults and TE (Testing Effort). It is verified to describe real testing process well by actual failure data set and has better performance as compared to other models. Based

Furthermore, the optimal release policies given limited reliability objective and the uncertainty in actual total cost exceeding expected one are developed and elaborated. Finally, a numerical example and related data analyses are illustrated and parameter sensitivity analysis is performed.
