چکیده
Software systems have become business-critical for many companies. These systems are usually large and complex. Some have evolved over decades and therefore are known as legacy systems. These legacy systems need to be maintained and evolved due to many factors, including error correction, requirements change, business rules change, structural re-organization, etc. A fundamental problem in maintaining and evolving legacy systems is to understand the subject system. Reverse engineering is the process of analyzing a subject system (a) to identify the system’s components and their interrelationships and (b) to create representations of the system in another form or at a higher level of abstraction. In this chapter, we will discuss the problems, process, technologies, tools and future directions of reverse engineering.

In this paper, a bi-objective model is presented for dynamic and integrated network design of a new entrant competitive closed-loop supply chain. To consider dynamism and integration in the network design problem, multiple long-term periods are regarded during planning horizon, so that each long-term period includes several short-term periods. Furthermore, a chain to chain competition between t...
متن کاملExperiences Reverse Engineering Manually
Better understanding manual reverse engineering can make it and any associated systems reengineering more effective. We reverse engineered a version of a system (referred to as "BOS/X") in support of a broader reengineering effort. System reengineering goals and other circumstances dictated a focused, limited duration, manual reverse engineering exercise. This presented an opportunity to study ...
