Hi there,
I working with equipment requirements and minimum time that one can hire, in this case on a 4-weekly cycle. For example in week 1 I need one piece and in weeks 2 to 4 I need 0, then I need 1 for the first 4 weeks. Then if I need 2 in week 5 and 1 in week 6, then I need 2 from week 5 to week 8. Is it possible to do a formula that works that out if my weeks are in columns and then my equipment types in rows like in the example below?


Many thanks for the help.
