Thank you very much.

I am looking for a comprehensive survey on this very subject matter.

For the particular problem of stationary facility to scene (police stations/fire departments to crime scene/burning house), you should not use solutions to assignment problems.

From the locations of each stationary facilities, you should compute (pre-compute) a varonoid diagram (may be a network varonoid diagram) and assign each facility to an area. Whatever happens in that area, the associated facility dispatch an agent (police car).

When there is a shortage of agents, then use assignment calculation. In this way, we can get faster response time.

For talks, invite "lawshay@lawshay.com" for g-talk. (That account is g-talk possible, don't send a g-mail invitation).

For optimization problems, I think solving manually is too laborious, no matter which methods you use. Thus, we usually implement these models on a spreadsheet and solve it using various solver programs. I think this is the best way if it is possible. Even MS Excel can compute some LP models to an extent. I think I can solve both problems in 10 min using solver. However, some algorithms, (such as minimum spanning tree) cannot be calculated. In such cases, we will have to compute them manually. (Anyone is welcome to discuss on Management Science via mthhak@gmail.com. Thank you.)

Assignment Problem, Network Model, LP Model ေတြက MBA က Management Science မွာလည္း သင္တယ္ ဘယ္ဘာသာ သင္သင္ အဲ႔ဒါေတြနဲ႔က မလြတ္ဖူးလား မသိဘူးေနာ္ :( Inventory Model ေရာ တြက္ရလားဟင္
