a)
To track: The values in the decision variable cells and the objective cell when the selling price for basics vary from $220 to $350 in increments of $10.
Introduction: In linear programming, the unbounded solution would occur when the objective function is infinite. If no solution satisfied the constraints then it is said to be an unfeasible solution.
b)
To track: The values in the decision variable cells and the objective cell when the labor cost per hour for assembling vary from $5 to $20 in increments of $1.
Introduction: In linear programming, the unbounded solution would occur when the objective function is infinite. If no solution satisfied the constraints then it is said to be an unfeasible solution.
c)
To track: The values in the decision variable cells and the objective cell when the labor hours for testing vary from 0.5 to 3.0 in increments of 0.5.
Introduction: In linear programming, the unbounded solution would occur when the objective function is infinite. If no solution satisfied the constraints then it is said to be an unfeasible solution.
d)
To track: The values in the decision variable cells and the objective cell when the labor hours for assembling and testing an XP vary independently.
Introduction: In linear programming, the unbounded solution would occur when the objective function is infinite. If no solution satisfied the constraints then it is said to be an unfeasible solution.

- Consider two products A and B that have identical cost, retail price and demand parameters and the same short selling season. The newsvendor model is used to manage inventory for both products. Product A is to be discontinued at the end of the season this year, and the leftovers will be salvaged at 65% of the cost. Product B will be re-offered next summer, so any leftovers this year can be carried over to the next year while incurring a holding cost on each leftover unit equal to 20% of the product's cost. How do the stocking quantities for these products compare? Multiple Choice Stocking quantity of product A is higher. Stocking quantity of product B is higher. The answer cannot be determined from the data provided. Stocking quantities are equal.arrow_forwardYour company currently keeps a safety stock of 554 units of a particular product that has a lead time of 10 days. Records indicate that the weekly demand was as follows: 1176 955 780 1052 736 842 748 993 852 738 794 1444 1333 1372 1106 706 923 734 786 729 1357 1165 1277 683 1106 What is the current service level? Input your result as the decimal form and round to 4 decimal places. You are requested to recommend a safety stock that will ensure an average service level of 97.5%. The lead time is not expected to change. What safety stock would you recommend?

- UC is catering an event on campus in TUC - that last time they did this they ran out of plastic silverware! We want to make sure we have enough and are looking at quantity discounts. To order less than 2,000 the vendor quotes $1.80 per piece. Orders between 2001 to 5,000 are $1.60 per piece and 5,001-10,000 it's $1.40. Any orders above 10,000 the price drops to $1.25. Ordering costs are $200 per order and to store the materials we have a 5% storage costs from UC catering. Our estimated annual demand is 15,000 pieces.

- Red Corporation uses the reorder point model to plan its purchases. It sells its sole product at the following daily amounts: Minimum=30,000; Average=40,000; Maximum=60,000. Its supplier takes 3 days on average and 4 days maximum to deliver the order.

There is a fixed delivery charge of 2000 dollars for each lot of motorcycles ordered from the distributor. It costs 1600 dollars per year to store a motorcycle. How many motorcycles should be ordered in each lot in order to minimize inventory cost (storage plus reorder)? Round your answer to the nearest integer.arrow_forward
