Thank you Jay. It worked after recalculating the spatial index. I have one more question related to ArcLogistics. What is the differences between ArcLogistics and Nwtwork Analyst extensions? My research area is modeling Biofuel supply logistics. Do you believe ArcLogistics have more capability and advanced tools than Network Analyst ? Thanking you for your help and contribution to solve my problem. God bless you. Regards, SAHOO

Thank you J. Sandhu and appreciated for your time. I have tried a lot figure out the problem of slow loading of data into Facilities & demand Points NA layers with my 50000 location points but i failed to do so. Sometimes it is taking less time sometimes more than 10 hours. Lets see the spatial index of two roadnetwork data layers. I believe both have same spatial index defined but one (1st figure) took minutes and other (2nd figure) took more than 10 hours or more. Please can you explain with an example or tutorials. Let me provide a material which can clarify my problem. Figure -1 (took 20 minutes to upload 50000 points) [ATTACH=CONFIG]24843[/ATTACH] and figure-2 ( waited for 10 hours and only 4000 data points were uploaded) [ATTACH=CONFIG]24844[/ATTACH] Please look these figure and help me to clarify the issue of slow loading of data into the model. I really feel frustrated with this issue. Thanking you. God Bless you. Regards, SAHOO

Hi Everyone, I have 50000 demand locations for my research work. It took about 10 hours to load the 50000 points into demand points(as shown in figure) of Location-Allocation extension of ArcGIS 10.1. I have created all polygon files (points, lines) in a file geodatabase and try to load the demandLocations into the DemandPoints of location-allocation extension of ArcGIS (as shown in figure). Please help me and let me know is there any other/faster way to load locations to the Location-allocation module of ArcGIS10.1. [ATTACH=CONFIG]24820[/ATTACH] Thanking You. Regards, KK

Hi Thank you for ur time. My problem has an around 80,000 supply (sources, can supply tons of material) points and 200 possible plant locations (facilities). Each supply point can supply a fixed amount of material (tons of materials) to the possible facilities (plants). I want to find the best 10 possible locations of plants to minimize the total transportation cost. Here transportation cost will be distance x tons of materials supplied to the plant. I believe the facility location model select the possible location towards the sources having large number of tons of supply materials. Does the location-allocation module in ArcGIS 10.1 model this problem? How to input the individual capacity of the sources into the location-allocation module in arcgis10.1. Your insightful thought is appreciated. Regards, KK
