water demand forecasting using neural network

my project is to develope and ANN network which will forecast water demand depending on previous consumption and temperatuer.i have per day consumption data from year 2005-2011 i want to use this data and predict cnsumption for 2011 so how can i design a neural network for my application. plz help.regarding the same as i am new to neural network.

Start by reading the documentation and try to reproduce the timeseries forecasting examples. Additional information can be obtained by searching the Newsgroup using the search words

 timeseries and/or forecasting.

Hope this helps,

hello sir,

but how to use nntool for my application

[niranjan sane]

hello sir,

i am using nntool of matlab for my prediction my application is to forecast water demand based on previous consumption.

year month day net supply

2003 1 1 2900

2003 1 1 2915

.

.

2010 12 31 3400.

my input matrix has 3 inputs month day and date and output matrix is simply net supply.i have trained my network using

nntool i got good results in training,validation and testing.ie(0.93).but when i try to simulate the network using nntool to forecast the consumption

for 2011 year i am not getting good results.

i mean if the actual consumption on 1st jan 2011 is 3400 i am getting it as 2900.

can you give me any sugession how to improve the results.
