The method of rescheduling the production of a lot to one or more prior periods if the increase in the holding cost is less than the cost of a setup also can be used when no capacity constraints exist. This method is an alternative heuristic lot scheduling technique for the uncapacitated problem. For Problem 14, start with a lot-for-lot policy and consider shifting lots backward as we have done in this section, starting with the final period and ending with the first period. Compare the total cost of the policy that you obtain with the policies derived in Problem 14.
