Based on the situation of the industrial symbiosis network (ISN), for the improper flow of information, the paper uses the coordination function of administrative organization as a tool, and analyzes the influence on the stability of by-products material flow by administrative organization. From the statistical aspect, through building modeling of material stability of by-products, and analysis of theoretical mode and its parameter influence, we then further find the by-products administrative organization is capable of coordinating the by-products material flow within the network between the enterprises, removing the variance of by-products material flow, and then promoting the stability of the by-products material flow between the ISN node enterprises.

A measuring approach for figure size from 3D human point cloud is presented.Using a light-stripe 3D laser scanning system to scan the desired pose of body,human's three-dimensional coordinates are obtained without loss.Based on the directions of eyesight and the natural separating of two legs,the human's orientation is adjusted to facing z positive direction.Applying manual method and maximal connectivity domain method to delete noisy points,6 figure points and 20 figure planes are labeled on human silhouette.Two different section planes' y coordinates are used to obtain one length size of human and a method,called convex hull method,to measure body section's girth,respectively.Using this technique,the 34 key figure lengths and girth sizes can be measured,and the factors affecting measurement precision can be analyzed.Measurement results show that the typical measurement error of this method is lower than 3% and can meet the requirement of industry.
