A fixed routes location problem and its algorithm

The problem of a fixed routes location with restricted conditions is very important in service of transport plan. This paper presents an improved quasi-physical model of location. The following object function is established max F(x, y) = (i=1)Sigma (n) g(1) (x, y).nu (l) = (i=1)Sigma (n)v(f)/1+(j=1)Sigma (m)(Di/d(if))(k) This model is more reasonable and more variable than former model. It can solve the situation when there exist more than one existing location. It supplies scientific foundation fur the location decision.
