[MI-L] Modelling Market Netowrks and Transportation Costs
I'm interested in any good information on modelling markets and transportation costs. I think this a problem that can be solved using network functions, but I'd like to know more about the factors involved in such a problem. For example, suppose you had 100 cities that either bought or sold widgets and there were various transportation routes between the cities with some variable cost associated with moving the widgets. How would you go about designing a program that could tell you the current price of widgets in Gotham? If you added a new transprotation route betwen cities or increased the carrying capacity of one or more routes, how would that affect the price in Gotham then? Assume that there is a variable supply at the producing centers, and in some cases the can produce more than they can sell, while in other cases they can't produce enough to keep up with demand. I was thinking that it might be like water flowing into and out of a network of pipes. There are inflow and outflow points, there is pipeline capacity (that may or may not be maxed out), and I guess if you add reservoirs at various points in the network you would affect the response of the system to changes in demand. Anyway I'm just trying to get a grip on this sort of problem, so if anyone knows of examples or what parameters are involved, or even how to go about modeling such a process, I'd be interested in learning more. - Bill Thoen ___ MapInfo-L mailing list MapInfo-L@lists.directionsmag.com http://www.directionsmag.com/mailman/listinfo/mapinfo-l
[MI-L] testing attribute of directory
Hi, I was wondering if anyone can help me before I delve into the windows API. I have the API call to get a list of files from a folder. I now need to scan these files and see if any of then are actually folders and not files. Does anyone know hoe to do this? Thanks Martin ___ MapInfo-L mailing list MapInfo-L@lists.directionsmag.com http://www.directionsmag.com/mailman/listinfo/mapinfo-l
[MI-L] MI 7 Window export
Testing the possibilities of vector format (png and emf) for insertion of a mapper window saved as into a Visio document, I have noticed that label size do not seem to follow window size redefinition before saving. That is, if I multiply by two the size of the window to be saved, label text is not increased proportionately. Do other versions than MI 7.0 have the same problem? Or am I way down left field passed the parking lot? Jacques Paris ___ MapInfo-L mailing list MapInfo-L@lists.directionsmag.com http://www.directionsmag.com/mailman/listinfo/mapinfo-l
[MI-L] Off the PRIMARY Subject - Microwave System Design GIS data software
Title: Message I've been tasked with doing a "discovery effort." My company is looking for a PC based GIS system / data that will help design Microwave communications systems. One of the challanges in Microwave design is that the designer must know about all potential 3D obstructions... Rather than using a TOPO map for the natural obstructions and doing extensive field work to determine man-made obstructions, etc. I ASSUME that there is some GIS based program that will help the engineers understand this. With all of the GIS talent on this list... can anyone point me in the right direction? Thanks! Tim This communication is the property of Qwest and may contain confidential or privileged information.

RE: [MI-L] Modelling Market Netowrks and Transportation Costs
Bill - I believe if you dive into looking up milksheds you will likely find several pathways to help sort this out. From decades past, the regulatory issues of milk basis versus dairies, collection points, competitive marketplaces, distance to markets, and more have been studied by agricultural economists and rural development specialists many, many times. There are two methods: spatial linear programming and/or network/friction surface analysis. While not an expert, I believe the most effective LP's need inputs (coefficients) from travel friction studies? Same ideas hold for grain transportation and competing modes: trucks, rail, barges... versus terminals, engineered waterways/highways/rails, and market basis. The LP stuff I will leave to you to dig into. Its history is quite deep given that the LP stuff was used to determine location of some our first interstate highways back East, in particular how they would interrelate to the milksheds surrounding New York, Boston and points between. The alternative would be the adjusting of several spatial analysis abstractions that Dr Berry has offered on his MapCalc related web pages: http://www.innovativegis.com/basis/Senarios/Default.html I believe friction surface as a proxy for speed and its travel complexity, start/go, uphill/downhill, combined with markets (ATMs in the example below) might be a conceptual start? Change the friction surface by changed assumptions and new flows occur. In this particular example, bank customers versus bank ATM locations, the friction surface is rather a simple one. And as they say time is money. Flows can be converted into cost/distance analysis. Net profits at end points can be guessitimated by margin analysis and simple assumptions on price elasticy? Travel-time and Customer Access http://www.innovativegis.com/basis/Senarios/TTime_scenario.htm Surface flows that conduit consumers to markets also have cost or friction surfaces. Pooling are essentially flows that can not achieve velocity. Mapping Surface Flows and Pooling http://www.innovativegis.com/basis/Senarios/Pooling_scenario.htm Dr Joe also has several books and in particular tutorials in the MapCalc Learner that will also illustrate other tricks to establish friction surfaces and impediments to natural flows... as the crow flies is not how you really get there... but if you build a bridge over a river, natural pathways change. Hope this might offer some insights.
