摘要翻译：
大学排课(UTT)是一个复杂的问题，由于它的组合性质和所涉及的约束类型。（约束）编程的圣杯：“用户陈述问题，程序解决它”仍然是一个挑战，因为解决方案的质量与导出“有效模型”紧密相连，最好由技术专家处理。本文针对高校排课这一领域，介绍了一个可视化的图形沟通工具，它通过可视化的实体-关系模型，让用户以抽象的方式描述自己的问题。这些实体主要是两种类型的节点：资源节点（讲师、助理、学生小组）和事件节点（讲座、实验会话、教程）。节点之间的链接表示它们之间期望的关系。可视化建模抽象关注实体的本质及其关系，并从实际约束模型中抽象出来。

英文摘要：
University timetabling (UTT) is a complex problem due to its combinatorial nature but also the type of constraints involved. The holy grail of (constraint) programming: "the user states the problem the program solves it" remains a challenge since solution quality is tightly coupled with deriving "effective models", best handled by technology experts. In this paper, focusing on the field of university timetabling, we introduce a visual graphic communication tool that lets the user specify her problem in an abstract manner, using a visual entity-relationship model. The entities are nodes of mainly two types: resource nodes (lecturers, assistants, student groups) and events nodes (lectures, lab sessions, tutorials). The links between the nodes signify a desired relationship between them. The visual modeling abstraction focuses on the nature of the entities and their relationships and abstracts from an actual constraint model.
