Over the past 30 years, many software reliability growth models (SRGMs) have been proposed for estimation of reliability growth of products during software development processes. Usually it is assumed that detected faults are immediately corrected when mathematical models are developed. This assumption may not be realistic in practice since the time to remove a detected fault depends on the skill and experience of personnel, the size of debugging team, and so on. Besides, during software testing, practical experiences show that mutually independent faults can be directly detected and removed, but mutually dependent faults can be removed if and only if the leading faults have been removed. Thus, the dependent faults may not be immediately removed and the fault removal process lags behind the fault detection process. In this proposal, we will discuss the software fault dependency and study how to incorporate both fault dependency and debugging time lag into software reliability modeling. We also noticed that most SRGMs do not take into account possible changes of testing-effort consumption rates. However, in some cases, the policies of testing-resource allocation could be changed or adjusted. Thus, in this proposal, we will incorporate the concept of multiple change-points into Weibull-type testing-effort functions. Based on the proposed SRGM, constructive rules are developed for determining optimal software release time in terms of cost-reliability criterion. The main purpose is to minimize the cost of software development when a desired reliability objective is given. In addition to SRGMs, the attractive rate-based simulation approaches have been proposed to describe the fault detection and correction processes during software testing phase. Thus far, it appears that most existing simulation approaches do not take into account the number of available debuggers. In practice, the number of debuggers will be carefully controlled. If all debuggers are busy, newly detected faults may have to wait (for a long time to be corrected and removed). Therefore, in this proposal, we will apply the queueing theory to describe and explain possible debugging behavior. Two simulation procedures are developed based on G/G/∞ and G/G/m queueing models, respectively. The analysis through the proposed framework may greatly help project managers to assess the appropriate staffing level for the debugging team from the standpoint of performance and cost-effectiveness. -- ▄ ◢ ▄▄▄ ▄▄▄ ▄ ▄▄▄ 清大資工 █ █◣◢█ █▄█ █▄█ █ █▄▄ Judylin 從 140.114.88.144 █ █◥◤█ █ █ █ █▄▄ █▄▄ 【楓橋驛站】 telnet://imaple.tw -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 140.114.71.60
