Dormitory is related to the quality of life of students during their school days, which directly or indirectly affects their life, study and healthy growth. The design of the use area, layout and facilities of student dormitories should not only make students' lives comfortable, but also facilitate management, and at the same time, the balance between costs and fees should be considered, which is also related to the region, location, cultural customs and economic development level of the city. Therefore, the design of student dormitory must consider the issues of economy, comfort and safety.

Economy: construction cost, operating cost and charging standard.

Comfort: per capita area, easy to use, non-interference, lighting and ventilation.

Safety: evacuation and theft prevention.

Attached are four typical student dormitory design schemes. Please make a comprehensive quantitative evaluation and comparison of their economy, comfort and safety through mathematical modeling.
