Reverse Engineering is focused on the challenging task of understanding legacy program code without having suitable documentation. Using a transformational forward engineering perspective, we gain the insight that much of this difficulty is caused by design decisions made during system development. Such decisions `hide' the program functionality and performance requirements in the final system by applying repeated refinements through layers of abstraction, and information-spreading optimizations, both of which change representations and force single program entities to serve multiple purposes. To be able to reverse engineer, we essentially have to reverse these design decisions. Following the transformational approach we can use the transformations of a forward engineering methodology and apply them `backwards' to reverse engineer code to a more abstract specification. Since most existing code was not generated by transformational synthesis, this produces a plausible formal transformational design rather than the original authors' actual design. A by-product of the transformational reverse engineering process is a design database for the program that then can be maintained to minimize the need for further reverse engineering during the remaining lifetime of the system. A consequence of this perspective is the belief that plan recognition methods are not sufficient for reverse engineering. As an example, a small fragment of a real-time operating system is reverse-engineered using this approach.

softwareprocess improvement has taken a very important role and awareness in the small organizations. Every day organizations initiate and develop new techniques to manufacture qualitative softwareproducts. Only few of them, able to achieve the desired results. Organizations mainly focus on the product quality rather on the processes which in fact make the product. the great amount of software organizations of the world are of small kind. these organizations have realized that it is essential for them to improve their processes and working technique but they lack in resources and the information for execution. In this paper, diverse literature on softwareprocess improvement in the small organizations had been reviewed. the purpose is to find out the critical success factors and the barriers for the small organization in the successful implementation of softwareprocess improvement program.

In order to improve human-machine matching in the field of automobile manufacturing, shorten the assembly production cycle and improve the existing assembly mode, according to the product assembly process flow. Risk management of automobile assembly process was carried out by identifying risk points and the LEC method, and the safety ergonomics of instrument panel assembly process was studied by JACK simulation software. First, virtual man-machine engineering simulation was carried out on the assembly process of the assembly process instrument. through the action decomposition of the instrument panel assembly process, the environment and human body were simulated. Second, using the lower back spine of the assembly process, static strength prediction, working posture analysis, and rapid upper limb assessment research, it is identified that the movement of controlling manipulator grasping the dashboard and loading into the car skeleton has the risk of personnel health injury. Finally, the assembly process design was improved for safety man-machine, the improved operating environment and operation process were simulated and *** results show that the man-machine relationship, working environment and operation process are improved through parameter optimization,and it provides a new idea and method for man-machine matching degree in automobile assembly process.
