You can use the service area to select the demand location and candidate facility locations that fall inside it and then load only those into the Location-Allocation and solve. Is that what you need to achieve? Or do you have some other constraint? Jay Sandhu

The Location-Allocation solver always needs to have a set of candidate locations to choose from. In real life there are many constraints that will restrict placing a location at the most ideal position. For example there may be a swamp or an already existing structure. So in case you do not have viable locations where you can locate a facility then you can make a synthetic data set. You can create a grid of points spaced 1 mile apart (or what ever distance makes sense for your problem area) and use them as the candidates or you can use the Create Random Points tool and create points spread out in your study area.

Generally in Location-Allocation, it is an all or nothing assignment. A demand point is assigned to the closest chosen facility. In the market share/target market share options, the allocation shows the probability of allocation to various chosen facilities. Can you describe your use case on how/why the demand should be split to more than one facility? Jay Sandhu

The explore network capability was added in Pro 2.9. Read more here: Explore Network—ArcGIS Pro | Documentation With OSM data, one thing to watch out is the connectivity policy of the network dataset. Usually it should be AnyVertex instead of the default Endpoint connectivity. Jay Sandhu

The input facility locations are snapped on to the closest place on an edge. So the "yellow points", I am assuming these are the facility locations after being loaded into a service area layer may be different then where your original points were. You mention that all your points are at nodes of streets. Are you using your own network dataset (same streets as where these should be nodes)? In that case they should locate at the same location. If some facilities do not generate polygons then it could be because the underlying streets are restricted or some other connectivity issue. You can use the Explore Network tool to check connectivity and attributes of the underlying network dataset. Polygons need to be converted to one or more points before being used in Service Area solver. Generally you could use the centroid or you could place a point at the park entrance or you could find the locations where the park boundary intersects with streets and place multiple points to represent that park.

You can compute the cost or distance between the candidate warehouse locations and the demand points for each of the travel modes and then come up with a way to combine the results for your purpose. The OD Cost Matrix solver can be used for computing the cost matrix. You can use the Location-Allocation solver to solve for optimal locations based on each of the three travel modes and then evaluate the results to see which gives overall minimum solution. Jay Sandhu

The explore network was added in 2.8 So you can try with the Service Area solver and do a 10 minute (or 10 Mile) service area with lines output. This should be a good way to know if you are getting connected lines coming back. Also just to be sure, you are not adding the stop points as being part of the network dataset, right? Just the lines that come from OSM? Jay Sandhu

It could be a data issue. I am assuming you are using ArcGIS Pro. There is an explore network option that you can use to inspect your network data. So, add the network dataset to your map and make it the active layer, then use the network dataset layer data tab to select the Explore network and click on some edges in the map. Inspect the connectivity, cost attributes and restrictions to make sure the network is built correctly. If that looks ok, then try the Service Area solver with the lines option to see if you are getting connected lines output from a starting facility location. Jay Sandhu

The Solve LocationAllocation tool is one of the Ready To Use tools, that is, it is configured to use ArcGIS Online to solve the location-allocation process and bring back the results. This is an older way of accessing our online logistics capabilities. In Pro, you can solve location-allocation (and other network analysis) either using your own local network dataset without using credits or you can use ArcGIS online with credits. The basic network analysis workflow is that you create an analysis layer (e.g., use Make Location-Allocation Layer) and then set its network dataset (local or online), configure its parameters, then use Add Locations tool to load in the facilities and demand and connect to the Solve tool to solve that analysis layer.

Sometimes there are highways crossing each other with on/off ramps where one facilities service area may go over another one because the lines that make up the service areas did not meet at a place that can be split between two facilities. The polygons are drawn around the lines that are serviced from each facility. In the picture you attached, you could also draw the street network and see if that is the case. Jay Sandhu

There are going to be practical limits to anyhing. Online services have limitations that are discussed here (expand the See Requests Limits link: Routing service | Documentation | ArcGIS Developer Desktop limits are discussed here (see the Limitations section towards the end): Vehicle routing problem analysis layer—ArcGIS Pro | Documentation If you plan to host your own services then yes, you will need to have your own street network dataset (or get Esri's Streetmap Premium product).

On the model build ribbon tab, use the Utilities drop down and add the Select Data tool to the model. Now you can connect the output of the solve to this select data tool and then choose to extract any of its sub layers such as the Lines. Jay Sandhu

I do live in So Cal! And I understand that it sounds optimistic. We do take this feedback back to our data team and vendors for evaluation. Thanks, Jay Sandhu

A solve for Tuesday 7:30 PM time uses the historical travel times when creating the service area. Cerritos to Long Beach is about 15 miles, so a 20 minute drive seems reasonable to get there. Also note that the historical travel times are averages for all Tuesdays in the last few years and the last two has had lighter traffic due to the pandemic. BTW, in your estimate, how long should it take to drive from Cerritos to Long Beach? Jay Sandhu
