摘要:在协作任务仿真模型的基础上,提出一种认知协作遍历检查技术,给出其遍历过程算法。通过第 1 阶段的评估对比实验,证明该
可用性评估技术适用于设计早期的协同软件系统,且评估成本较低,效率较高。在第 2 阶段实验中增加了评估者的数量,用以分析评估者
数量及其个体表现对评估结果的影响,并针对一般情况下获得最高收益代缴比的样本数量给出建议。

【Abstract】On the basis of Cooperative Task Simulation Model(CTSM), this paper proposes a cognitive cooperation walkthrough inspection
technology, and designs its walkthrough process algorithm. The first parison experiment validates that the usability evaluation technology
is suitable for cooperation software system at early design, and it achieves low cost and high efficiency. The number of evaluators is increased in the
second-stage experiment. How the quantity and individual performance of evaluator affect the evaluations result is analyzed. The number of samples
to gain the highest cost-effective ratio for general evaluation is suggested.
【Key words】cognitive cooperation walkthrough; cooperative task simulation; usability
