- Please do not give solution in image formate thanku. Consider a firm that operates a cannery. All fish brought in by a fleet of fishing boats are processed at the cannery. The firm also has a freezer of unlimited size that stores unprocessed fish. Assume that the freezer is empty in the beginning of the year. There are three seasons. The fleet yields 8400 tons/month during the first third of the year, 11200 tons/month during the middle third, and only 1400 tons/month during the final third. The cannery's processing capacity equals 7000 tons/month. a- What is the inventory level at the end of January?

Delta is trying to reduce warehousing costs and establishes three policies to that end: i) The annual number of orders for all products must be at least 20 per contractual terms with transportation providers. ii) The average inventory in units must be a maximum of 1800. iii) Because the raw material is perishable, there can never be more than 2000 units in inventory of raw material 1. Raw material 2 has a maximum allowed of 1200 units and the raw material 3 can store maximum 400 units. The following table shows the product information: Materia Demanda Costos por unidad Costo por prima (u/año) ordenar ($) 2200 2 300 2 500 4 650 3 3000 10 100 Consider an interest rate of 10% per year.

- In the fashion retail industry transshipment is the flow of the products from a retail location to another one to satisfy the demand at the receiver location. Sender only sends a product if it has excess inventory to its demand and it occurs to rebalance the inventory among retail locations. Assume that there is a retailer with I stores. There are O products nominated for transshipment. The available inventory rio, i = 1,2, ..., I, o = 1,2, ..., 0, and demand levels dio, i = 1,2, ..., I, o = 1,2, ..., 0, for all O, stores are known. Moreover, the sales prices of these products are known and are the same in all stores, po, o = 1,2, ... 0. There is a transportation cost when a product is sent from a store to another, Cij, i, j = = 1, 2, ... D which is independent for the type of the product. Assume that if a product o is transshipped from store i, all its available inventory, i.e., rio, must be sent to a single store, thus, partial transshipment is not allowed. However, a store can…The Frist Corporation has the followinginternal controls related to inventory:1. Only authorized inventory warehousing personnel are allowed in inventory storageareas.2. All inventory products are stored in warehousing areas that are segregated fromother storage areas used to house equipment and supplies.3. All inventory held on consignment at Frist Corporation is stored in a separatearea of the warehouse.4. The inventory purchasing system only allows purchases from pre-approved vendors.5. The perpetual inventory system tracks the average number of days each inventoryproduct number has been in the warehouse.6. Microchips are embedded in each product and when inventory items are removedfrom the warehouse to shipping, radio-frequencies signal a deduction of inventoryto the perpetual inventory system.7.

Each icecream costs $0.5 to make and there are $40 as a fixed maintenance cost per stall. 1. Find the optimal number of stalls for Maribel? 2.What is the profit at optimal number of stalls?
- Happy Henry’s car dealer sells an imported car called the EX123. Once everythree months, a shipment of the cars is made to Happy Henry’s. Emergencyshipments can be made between these three-month intervals to resupply the carswhen inventory falls short of demand. The emergency shipments require twoweeks, and buyers are willing to wait this long for the cars, but will generally goelsewhere before the next three-month shipment is due.From experience, it appears that the demand for the EX123 over a three-monthinterval is normally distributed with a mean of 60 and a variance of 36. The cost ofholding an EX123 for one year is $500. Emergency shipments cost $250 per carover and above normal shipping costs.a. How many cars should Happy Henry’s be purchasing every three months?b. Repeat the calculations, assuming that excess demands are back-ordered fromone three-month period to the next. Assume a loss-of-goodwill cost of $100 forcustomers having to wait until the next three-month period and a…3.

- In a large microelectronics plant, the assembly cell for circuit boards has a demand for 300 units an hour. Two feeder cells supply partsA and B to the assembly cell (one A and one B for each board). Standard containers that look like divided trays are used. A container will hold 22 As or 13 Bs. It takes 13 minutes to fill up a container with As and 22 minutes to fill up a container with Bs. Transit time to the assembly cell is 5 minutes for both A and B. No safety factor is used.
