Pleаse write dоwn yоur steps аs requested in the questiоns together with your results. The grаdes will be given based on necessary steps (10 points) Please formulate a linear programming for the network of a transshipment problem below. The values under the nodes are supply amount (negative value) or demand amount (positive value); the values above the arcs are the shipping costs. (8 points) A company prints a Christmas card once a year and distributes the cards to and gift shops in the United States. It costs 50 cents to print each card, and the company receives 65 cents for each card sold. Because the cards have the current year printed on them, those cards that are not sold are generally discarded. Based on past experience and forecasts of current buying patterns, the probability distribution of the number of cards to be sold nationwide for the next Christmas season is estimated to be Quantity sold Probability 100,000–150,000 0.10 150,001–200,000 0.15 200,001–250,000 0.25 250,001–300,000 0.20 300,001–350,000 0.15 350,001–400,000 0.10 400,001–450,000 0.05 Determine the number of cards that company should print this year. (16 points) A local store produces candles. The average weekly demand is 44. It purchases the glass containers with $3 each, and the holding costs are based on a 20 percent annual interest rate, the setup cost of a purchase order is $132. The net requirements of the glass containers for the next six weeks are as follows: Week 1 2 3 4 5 6 Net requirement 50 50 20 10 20 100 a) (6 pts) Please use EOQ formula to determine the planned release amount (in integer) in each purchase order and schedule them in the follow table. Please write down your steps.
