英文摘要ABSTRACT 英文摘要 ABSTRACT Requirements Engineering(RE)is branch of SoRware Engineering，whose activities involve requirements elicitation,requirements analysis，requirements specification，requirements validation and requirements management． ne Unified Modeling Language(UML)，which is designed by Rational Software Corporation and its partners，pmvides system architects working on object analysis and desigu、析m one consistent language for specifying，visualizing， constructing and documenting the artifacts of software systems．The thoughts and methods in the UML have the directly guided significance and practically applied value for the activities of requirements engineering．as well as for those of software engineering．UML is the convergence of best practices in the object--technology Industry． And It Is a rich； precise，extensible modeling language for Object--Oriented system development and Software developing automation environments．UML is the representation ofexcellent software engineering methodology which is approbatory in large--scale and complex modeling field． Although system development flow is the background of UML application，UML is oray standard modeling language and not standard development flow．Different organizations and different application field has different development process．During the ofsothvare developing：requirement analysis iS decisive step．The lemma ofthis article is to discuss UML apphcation on requirement analysis．Finally,this thesis builds the model of the Products Survey Management Information System(PSMIS) with UML． This paper firstly expounds the fundamental concepts and methods of software nxluirements engineering and of the UML．Secondly,based UML，the paper describes the RE’S practicing process and part outcomes of Products Survey Management Information System (PSMIS)， and emphasizes particularly on requirements elicitation,requirements analysis and requirements specification． Key words：Requirements Elieitation，Requirement Analysis，Requir
