- A drug store sells 30 bottles of antibiotics per week.Each time it orders antibiotics, there is a fixed ordering costof $10 and a cost of $10/bottle. Assume that the annualholding cost is 20% of the cost of a bottle of antibiotics, andsuppose antibiotics spoil and cannot be sold if they spendmore than one week in inventory. When the drug store placesan order, how many bottles of antibiotics should be ordered?An electronics retailer sells laptops at a steady rate of 7,500 per quarter. It costs the manufacturer $350 tomake each laptop, and they charge $400/laptop to the retailer. The manufacturer produces the laptop at asteady rate that matches demand, and incurs a fixed cost of $2,800 to fulfill each retail order. Both theretailer and the manufacturer have an annual holding cost percentage of 20%. The retailer places 10orders with the laptop manufacturer each quarter (which it determined from an EOQ calculation). What quantity discount should the manufacturer offer the retailer in order to minimize the total supplychain costs?Estimate the effort, time, production and the number of personnel necessary for the development of a Communications system that has a size of 30,000 LDC. In this project there are factors that influence the development and ensure the proper functioning of the system. These are: Complexity of development, staff qualification and advanced knowledge of the language in which it will be developed. Each factor in the order described has a weighted value of 1.15, 0.7 and 0.91 respectively. It is important to mention that the monthly payment per person working in the development is $2,200.

Two gaseous streams containing the same fluid enters a mixing chamber and leaves as a single stream. For the first gas the entrance conditions are A1=500 cm², v1=230 m/s, p1=1.60 kg/m³. For the second gas the entrance conditions are A2= 300 cm³, m2=8.84 kg/s, v2=0.502 m³/kg. The exit stream conditions is v3=130 m/s and v3=0.437 m3/kg. Determine the following: (a) the total mass flow leaving the chamber (kg/sec) (b) the velocity of the gas at 2. (m/sec)Engineering Economy A company has determined the price and the monthly demand of its products are related by the equation D = √775 - p, where p is the price per unit in dollar and D, is the monthly demand. The associated fixed costs are $2,125 per month and the variable costs are $100/ unit. Use this information to answer the following: a)What is the optimal number of units that should be produced and sold each month? b) What is the maximum profit? c)Determine the value of D that represents the break-even point?You own a wheat warehouse with a capacity of 20,000bushels. At the beginning of month 1, you have 6,000 bushels of wheat. Each month, wheat can be bought and sold at theprice per 1000 bushels given in Table 46.The sequence of events during each month is as follows:a You observe your initial stock of wheat.b You can sell any amount of wheat up to your initialstock at the current month’s selling price.c You can buy (at the current month’s buying price) asmuch wheat as you want, subject to the warehouse sizelimitation.Your goal is to formulate an LP that can be used to determine how to maximize the profit earned over the next 10months
- The analyst in the Dorben Company wishes to assign a number of like facilities to an operator based on minimizing the cost per unit of output. A detailed study of the facilities revealed the following: Loading machine standard time = 0.30 minutes Unloading machine standard time = 0.25 minutes Walk time between two machines = 0.09 minutes Operator rate = $12.00 per hour Machine rate (both idle and working) = $18.00 per hour Machine cycle time = 1.55 minutes TEC = The Expected Cost a) With your initial estimation, how many machines can be serviced exactly?(please keep a non-integer with three decimal places) b) How much is your TEC per piece if the operator has idle time?

Even though often using an EOQ policy, the manager never considered a backorder model because of the assumption that backorders were “bad” and should be avoided. However, with upper management’s continued pressure for cost reduction, you have been asked to analyze the economics of a backorder policy for some products that can possibly be backordered. For a specific product with D = 1200 units per year, Co = 160, = 4, and = 25, what is the difference in total annual cost between the EOQ model and the planned shortage or backorder model? If the manager adds constraints that no more than 25% of the units can be backordered and that no customer will have to wait more than 18 days for an order, should the backorder inventory policy be adopted? Assume 300 working days per year.
