The Summarize of Facilities Location and Advice on Precast Concrete Component Factory Location.

By means of software including Citespace and SATI 2668 literatures with "location problem" as the keywords in CNKI database were clustered and visualized. Research hotspots of location problem including site selection model and algorithm were analyzed to select the most suitable site selection model for PC component factory. Through the analysis the scale of PC component factory is large and the investment payback period is long thus the selection of PC factory is attributed to the single facility site. Based on the comprehensive evaluation method this paper summarizes the factors of site selection for PC factories, which is beneficial for selecting the suitable alternative location. This study uses the model to make quantitative evaluation of each alternative location and finally decides the location with the lowest total cost. [ABSTRACT FROM AUTHOR]
