IE 1055 2025 Homework 9 Due March 29 2017 1 18 pts Critique of sample project one 2 18 pts Critique of sample project two 3 18 pts Analyze the following vaccine capacity problem The packaged volume of single dose vaccines is given in the table below At a given location you need to have 11000 doses of each vaccine type The location you are analyzing uses refrigerators with storage compartment dimensions of 24 inches by 20 inches by 18 inches Assuming all vaccines are only stored in the refrigerator how many refrigerators do you need Fully justify your answer Vaccine Name DTP DTP HepB Hib Measles Oral Polio Tetanus Toxoid Tuberculosis Yellow Fever Packaged volume in cm3 3 9 7 3 5 1 3 1 2 2 5 Solution 18 pts Calculate the storage space inside the refrigerator 1 in 2 54 cm 24 2 54 20 2 54 18 2 54 141584 2 cm3 Sum the packaged volumes and you obtain 23 9 mL 1 cm3 1 mL then multiply the total number of doses needed by the total packaged amounts 3 9 7 3 5 1 3 1 2 2 5 11000 262900 cm3 Assuming we get 100 utilization of the refrigerators the volume per refrigerator is 141 6L or 141584 2 mL If we divide our total volume of packaged vaccines by the volume per refrigerator we get 262900 141584 2 1 86 Refrigerators needed If we assume that we can only get 90 utilization of the volume in the refrigerator the adjusted volume is 9 141584 2 127425 8 mL Using the same methodology as above if we divide 262900 127425 8 2 06 Refrigerators needed In reality you are probably doing well to get 75 utilization of the refrigerator For 75 the adjusted volume is 75 141584 2 106188 2 mL Using the same methodology as above if we divide 262900 106188 2 2 48 Refrigerators needed Thus overall it seems that 3 Refrigerators are needed THIS SOLUTION MAY ONLY BE USED FOR IE 1055 2025 SPRING 2017 4 13 pts At the MSA site in Cranberry they have chosen to receive all of their cardboard boxes used for test devices from their suppliers already constructed as opposed to receiving flat cardboard sheets sized and perforated as needed and constructing the boxes themselves These boxes are on average 4 8 inches long 2 4 inches high and 3 6 inches wide Discuss some of the pros and cons of using this strategy concerning cardboard boxes Solution 13 pts Pros Reduce assembly time because the boxes will not need to be set up Reduce assembly cost because less labor is required per test device Increase capacity of assemblers because of less time setting up boxes Reduce cost of materials to assemble boxes tape scissors etc Cons Boxes will be more expensive when pre assembled Storing assembled boxes takes up significantly more space than storing collapsed boxes Shipping costs will increase because of more space required to transport boxes i e less boxes per shipment Boxes are more likely to be damaged if stored transported when assembled as opposed to collapsed 5 18 pts MedTech is a manufacturer of disposable syringes used in the medical industry After the disposable syringes are manufactured and packaged there is an FDA requirement that the syringes be sterilized before they can be shipped from MedTech s facility The sterilization occurs in a large chamber and currently has a 12 hour cycle time including the time to load and unload the chamber MedTech currently has 3 sterilization chambers that have an average uptime of 98 The diagram below shows how pallets of syringes are loaded into the sterilization chamber The pallets are 48 inches by 54 inches and it takes about 10 minutes to load unload the pallets into out of the chamber The outer dimensions of the chamber are 14 feet by 28 feet and the usable area of the chamber that can hold pallets is 10 feet wide and 21 5 feet long MedTech currently runs the sterilization operation 24 hours a day 7 days a week 54 48 10 21 5 THIS SOLUTION MAY ONLY BE USED FOR IE 1055 2025 SPRING 2017 MedTech s current production schedule requires them to sterilize 300 pallets per week In the next year MedTech sees that increasing to 340 350 per week in two years to 350 375 per week and in three years to 380 400 per week In order to obtain increased sterilization capacity MedTech is considering the following options i Change the sterilization gas that they use in order to reduce the cycle time to 9 hours Changes to the equipment due to the gas conversion would cost 362 000 over the next 2 years Annual sterilization gas costs for the new gas would be roughly equal to the gas costs for the current sterilization gas ii Purchase an additional sterilizer of the type they currently have at a cost of 417 000 iii Outsource additional sterilization but the cost of outsourcing is 36 higher per disposable syringe than the cost of sterilizing in house Which option and or other ideas would you recommend to MedTech Answer 18 Pts Current dimensions of the 3 chambers are 10 x21 5 which translates to 120 x258 The current pallet configuration allows for floor 120 48 floor 258 54 8 pallets chamber The current situation allows for 8 pallets chamber 24 hrs day 12 hrs for cycle 0 98 utilization 3 chambers 47 04 pallets day At the end of a 7 day week MedTech can produce 7 45 6 329 28 or 329 pallets week This production rate is sufficient for current demand But will not be able to keep up with demand in future years Option 1 Reduce cycle time to 9 hours 8 pallets chamber 24 hrs day 9 hrs for cycle 0 98 utilization 3 chambers 62 72 pallets day At the end of the week MedTech can produce 7 62 72 439 04 or 439 pallets week This production rate is sufficient for predicted demand in three years The cost of this option is 362 000 over 2 years No other cost data was provided Option 2 Purchase a new sterilization chamber 8 pallets chamber 24 hrs day 12 hrs for cycle 0 98 utilization 4 chambers 62 72 pallets day At the end of the week MedTech can produce 7 62 72 439 04 or 439 pallets week This production rate is sufficient for predicted demand in three years The cost of this option is 417 000 No cost data such as the cost of labor needed to run the new machine was provided Option 3 Outsource Current production is 329 pallets week with expected demand of 400 pallets week in 3 years In 3 years MedTech would need to outsource the production of 400 329 71 pallets week The cost of this option is 36 higher than in house production for those outsourced syringes The cost of in house production is not given The profit margin on syringes was also not provided THIS SOLUTION MAY ONLY BE USED FOR IE 1055 2025 SPRING 2017 …
