Evening with friends in a chat friend told me Warehouse optimization planning thing, just start listening to friends talk about Warehouse after optimization planning and I have a little not understand after friends give me some examples I can understand, after listening to a friend to this program I say I feel this procedure if after using them to work it will be very good. A friend is to work in a software company, sometimes just out of the new program friend tells me, every time I listen to those procedures friends say I feel now the technology is too developed, also think friends are very nice job. Have a little want to know more about some of my friends work.
