The approach considers the spatial layout and the time scheduling simultaneously,and in the whole scheduling plan period,the algorithm is divided into two parts:the first is the pre-scheduling stage,the scheduling time is separated into the continual time-slices,and the block candidate set is got via the time constraint,the initial layout sta.

By introducing three-dimensional model,dyna-mic stereogram for components connected with equipment,installation and device configuration was demonstrated from multi-angles of view,which can conduce to spatial arrangement of device configuration during mineral processing plant design and improvement of efficiency and quality for design.

Based the characteristics of the cryogenic methanol-washing system for coal-based synhesis plant,the special piping requirements inengineering design are summarized in this artical for the designer' referrence.

The results showed that the improved software is suited to the piping layout design standard of China.

Through the forms of drainage tubes,it makes illustration in detail on each kind of tube layout and pavement,emphasizes the skill needs of some key parts and sections,meantime,it points out the importance of coordination with equipping in construction.

It discusses the daily drainage design from system,tube materials,appendix,venthole,tube layout and pavement as well as rain-water drainage,and analyzes problems which should be noticed during drainage design,so as to improve the general designing level of ours.
