Grace Greenberg, production planner for Science and Technology Labs, in New Jersey, has the master production plan shown in the table below, with the following additional

information:

Lead time $=1$ period;

Setup costs $=$ $$200$;

Holding cost $=$ $$10$ per week;

Stockout cost $=$ $$10$ per week. Develop an ordering plan for Grace, and compute the total costs for each plan, using the

following techniques:

a$)$ Lot$-$for$-$lot. b$)$ Fixed Order Quantity rule, where quantity Q is chosen as the EOQ quantity based on given

costs. Hint: To compute EOQ, assume the demand rate to be the average demand per week. c$)$ Fixed Order Period rule, where the period is computed as the EOQ divided by the average

demand per period $($rounded to the nearest integer$).$

d$)$ Which plan has the lowest cost?
