求人帮忙确定一个系统的所有use case吧，要开发一个论文评分管理系统
要求描述如下：
A system is required to maintain and manage reviews of technical papers for a large software engineering conference. The system must record details about each paper, including its title, author(s), and contact email address. (Please see appendix 1 for the list
of submitted papers.) A paper should have at least one contact email address. A programme committee (PC), which is guided by a programme committee chair, carries out the reviews of papers. (Please see appendix 2 for the list of PC members). Each PC member is allocated a number of papers by the PC chair. Note that a PC member cannot be assigned a paper where there is a “conflict of interest”, for example, where they are personally related to an author or are themselves an author of the paper. To avoid this, a
record is kept of which authors have a conflict with which papers. Each PC member then reviews their allocated papers, after which they must fill in a review form with detailed comments about the paper and an overall score. The score for a paper is collated from a number of key indicators, for example, novelty, clarity, length, importance and relevance. The reviewer must write comments to the reviewed papers. (Please see appendix 3 for a sample review form).
Once the review process has completed, decisions are made regarding the acceptance of papers. Based on its score, a paper can be rejected or accepted. The PC chair sets the thresholds for accepting/rejecting a paper. A paper is assigned a “voting” status when it is in between the thresholds for acceptance and rejection. In this situation it is up to members of the PC to vote on whether a paper should be accepted. To do this, PC members discuss the merits or demerits of each paper that is being voted on (but they
cannot vote or discuss papers where they have a conflict of interest). PC members can then vote for or against a paper as many times as they like, but only their latest vote is recorded. If they do not vote for a paper no vote is counted. Finally, once a certain time period is over, the votes are counted. Papers that gain more votes for acceptance than votes for rejection are accepted.
初步设想是三个actors: administrator,PC chair,PC member.
现在在finding use case 阶段。。不太确定了，尤其是管理员的use case，感觉能列出来很多。

楼主国院的吧，软工CW...
[解决办法]
把名词法，动词法看看～～
自己多练练有好处
祝你成功
[解决办法]
试着按部门分组，先找到外部参与者，内部参与者，然后根据参与者与系统的交互找到用例，前期要捕获大的场景，不要拘泥于细节，后面有充分的时间让你打开黑盒。
试着使用系统顺序图，也许对你有帮助。
建议看一看“编写有效用例”一书
