Description:
|
[*
|
Return the ratio of the period defination time unit's duration over the time unit's duration, takes length of time into consideration
|
E.g., period defination time unit's duration = 1 days, time unit's duration is 1 week, length of time = 2, return (1 / 7) / 2.
|
Argument time unit is get from unit capacity, unit availabilit or stocking point capacity. Same goes to length of time.
|
Argument period defination time unit is unit period or stocking point period's time unit.
