Hello,

I am just starting to work on linear programming and I have an issue on how to manage lead time.

As linear is often use to solve some productions problems, I guess there is an easy way to solve it but can't see how.

For example if you have to manage a stock, you have to know what comes from the previous days :
Stock[day] = Stock [day-1] + move [day-leadtime]

My problem is that if you have many stocks to manage and many different lead time I can't do the previous equation zithout reaching an out of range exception.

As move and stock are both decisions variables, they are declared as arrays zhose size is fixed.

Any ideas, current solutions to solve this kind of problems?
