The ability of a planner to reuse parts of old plans is hypothesized to be a valuable tool for improving eeciency of planning by avoiding the repetition of the same planning eeort. We test this hypothesis from an analytical and empirical point of view. A comparative worst-case complexity analysis of generation and reuse under diierent assumptions reveals that it is not possible to achieve a pro...

Tailor Welded Blanks (TWBs) made of dissimilar, uniform or non uniform thickness materials have potential applications in automobile industries for light weight materials in order to improve fuel efficiency and cost of carrier. The focus of this paper is to develop and present analytical model to determine total elongation of tailor welded blank (TWBs). The validation of this method is done by ...
