Abstract:Recently, the project team made progress in the following aspects. First, in requirement elicitation and collaborative optimization of information services, we (1) improved feature-oriented domain analysis requirement elicitation approach;(2) investigated use case driven requirement elicitation approach based on target scenario;(3) studied collaborative analysis and optimization method and developed the supporting tool. Second, we studied modeling and model evolution methods of information services including:(1) modeling and model evolution theory and approach base on Petri nets;(2) process algebraic based modeling and model evolution theory and method. Supporting tools are also developed. Finally, we investigated the following formal verification and confirmation approaches of information service models. (1) We studied model based testing theory and approach, and developed model based testing tool;(2) we presented symbolic and bounded model checking approaches of PPTL, and developed the corresponding model checkers;(3) we improved simulation theory and approach based on MSVL, and developed toolkit MSV;(4) we studied CEGAR based abstract model checking approach, and developed the supporting tool.
