主题：求助：简单的GIS软件（地理信息系统） -- 总公司

Now I got the whole pictuer, but:

1. This task should be assigned to accountants or business analysts. But it's not a big deal, you still can do that and I figured that you knew how to do that already. That's basically a supply chain problem which should be addressed by ABC (activity based costing) method.

2. SAP have ABC model and it should be used for this purpose if you or your company know how to configure and run it. If you have that working, then you can easily get the solution easily. If not I think you should talk to your manager or CEO to seriously consider this since it can bring tremendous savings. Although implementing ABC accounting for chinese company is a quite challenge task, which is very well known issue.

3. Without that, you still can do that as long as you find the right cost drivers and variables for different products, warehouses and vendors. Then you can use spreadsheet and matrix calculation to find the optimal solutions.

4. How to present the result is always the last step and last focus. To manager and accountants, numbers are more important that graphic presentation.

5. MS MapPoint will not work since it doesn't have china map. I am not quite sure about autocad.

Anyhow, hope this helps you more. Good luck and have fun.
