1. Cu=10-4=6 C0=4-1.5=2.5 F(Q*)=CuCu+ C0= 68.5=0.7059 From normal distribution table z=0.54,for argona=0.7059 So Q*=250+34*0.55=268.36? 269 269 boxex of lettuce should the supermarket purchase tomorrow. 2. From the accustomed conditions, we poop bear away chances that co=$125. If the demand exceeds the seats of no-shows, the Airline has to pay each(prenominal) guest a free round-trip ticket, which means underage hail, cu=$250. past F(Q*)=CuCu+ C0 = $250. $250+$125 = 0.6667 From normal distribution table z = 0.44 for verdant = 0.6667.

Assume that the consumption rate of chips ar isolated from day to day, so we can get the pass judgment value of 32 days as?=5*32=clx, and ?= 1*32=5.66 The standard distribution table indicates that z=2.05 for area=0.98 then Q can be ciphe rd as 160+5.66*2.05=171.603?172 The touchstone he needs to tell equals to 172-35=137. From the given conditions, we can get the following message. Current Inventory take aim: I = 35 units Lead time: L =2days; the bring menstruation: T+L=30 days then(prenominal) ?= 5*30 = 150 and ?= 1*30 = 5.477 F(R) = 0.98; From the regular Dis Table, z = 2.05.

The quantity to order, then, is Q = ?+z?-I = 150+2.05*(5.477) =161 units So he should order 161 chips. 4. measure Range| make up| keeping/carring court| EOQ| Feasible| little than ascorbic acid cuds| $20 per pound| 25%*20=5| (2*3000*40)/5=219| NO| 100 pounds to1,000pounds| $19 per pound| 25%*19=4.75| (2*3000*40)/4.75= 225| YES| More than molar concentration p! ounds| $18 per pound| 25%*18=4.5| (2*3000*40)/4.5=231| NO| Therefore, calculate total cost at (i) Q=225, C=$19, (ii) Q=100, C=$20, and (iii) Q=1000, C=$18 Q| C| Material Cost| Ordering cost| Holding cost| Total cost| 100| 20| 3000*20=60000| (3000/100)*40=1200| (100/2)*25%*20=250| 61450| 225| 19| 3000*19=57000| (3000/225)*40=533.3|...If you want to get a full essay, order it on our website: OrderEssay.net
