In recently years

with the increment of urbanization

the computer aided urban planning has become more and more important. Generally

the computed aided process is accomplished through the help of multiple software systems. There are several issues with the above solution such as weak applicability

lack of efficient auto-evaluation method

etc. The working principle and main modules of CAUPS are briefly introduced. The key technique for auto-evaluation

i.e.

the design and implementation of evaluation models definition system in CAUPS

is emphasized. A series of simple operations and resolution for the entity relations are firstly provided to describe all the possible evaluation models

and then users can customize their evaluation models by combining the proper entity relations and entities based on the practical planning demand.
