Sаlаde Nоrmаnde is the prоducer оf packaged salads that the company distributes throughout France and the Benelux area. Salads are mostly sold in large supermarkets (Carrefour, LeClerc, Champion) or at gas stations. All salads are shipped in a plastic bowl of 26-cm diameter with a smaller plastic bowl for the dressing inside. For its best-selling salad, the "Salade du Chef," the company operates a five-step process. The activities of the five steps and the associated processing times are shown in the following table. Station Tasks Processing Time (seconds) A Salad 1 Grab an empty bowl Fill with green salad Add five slices of tomatoes Total time for A 6 12 8 26 B Salad 2 Add four spoons of corn Add three rings of onions Add sliced cucumber Total time for B 10 8 13 31 C Add Meat Carefully cut four slices of meat Weigh slices and ensure a weight of 30–32 grams Add meat slices to the bowl Total time for C 20 17 8 45 D Add Sauce Container Grab a sauce bowl Add sauce Seal sauce bowl Put sauce bowl into salad bowl Total time for D 4 12 8 6 30 Seal Bin and Label Bowl Clean the outside of the bowl/wipe off the rim of the container Cosmetic inspection Seal container Label container Total time for E 8 9 14 7 38 Workers (one per station) get paid 15 euros per hour, and this type of salad is always in high demand (assume unlimited demand).

This pаge hаs 2 prоblems which I hаve termed as Optiоn A and Optiоn B. DO ONE OF THEM. You will not receive extra credit for doing them both. ------------------------------------------------------------------------------------------ OPTION A A printing company works on two types of printing jobs, each of which could be produced on the same model printing machine. The predicted annual demands and typical order sizes are shown in the table. The company has 2000 production hours available each year and requires a 10% capacity cushion to allow for preventive maintenance, breakdowns, and other unforeseen circumstances. Job Type Job A Job B Demand 6000 4000 Process time per unit (hour) .8 .75 Average order size 40 100 setup time (hours) 1 .75 How many printing machines must they have under these circumstances? (6 points) Formula END OF OPTION A -------------------------------------------------------------------------------------------------------------------------------------------- OPTION B A company makes two products that have the following characteristics: Product A sells for $50 but needs $10 of materials and Product B sells for $75 but needs $20 of materials.
