To determine: The values of
Introduction: From the past experiences, a big oil company can evaluate its present and the future costs. According to its study, each doubling of the size of a refinery at a single location results in the construction coststo about 68%.
b.
To determine: The best time to make additions in plant and the optimal size of each addition.
Introduction: Based on previous experiences, the oil company can easily predict the vivid picture of its present and future. Likewise, it can determine the optimal timing of plant additions and the optimal size of each addition too.
c.
To determine: The best timing to make additions in plant and the optimal size of each addition if the largest single refinery can be built with current technology is 15,000 barrels daily.
Introduction: When the major oil company installs the largest single refinery then its optimal size will not necessarily be huge while talking about the annual count. Similarly, the optimal timing of adding the plant will not necessarily be more always.

- Assume the demand for a companys drug Wozac during the current year is 50,000, and assume demand will grow at 5% a year. If the company builds a plant that can produce x units of Wozac per year, it will cost 16x. Each unit of Wozac is sold for 3. Each unit of Wozac produced incurs a variable production cost of 0.20. It costs 0.40 per year to operate a unit of capacity. Determine how large a Wozac plant the company should build to maximize its expected profit over the next 10 years.arrow_forwardA company has the following demand data for the last three years of sales for their popular product B. There are currently 5 workers assigned to the production line, each capable of producing approximately 8 units per month. It is assumed that each month has the same number of production days. They can hire more workers at a hiring and training cost of $800 per worker. If they layoff any workers, the unemployment cost is $2,000 per worker. The product has a standard production cost (labor, material, and overhead) of $300 per unit. The extra cost to produce one unit on overtime is $50 and the maximum overtime is two units per month per worker. They can use inventory but it will cost them $25 per unit per month for any unit in inventory at the end of the month. Failure to meet market demand typically will imply the customer will buy from another supplier, and therefore cost the company $100 in profit. They currently have 0 units in inventory. a.

- A steel production plant manufactures bands and coils which sell at a profit of $25 and $30 per ton,respectively. The production rate of the plant for bands is 200 tons/hr, and that for coils is 140 tons/hr.Based on the market analysis, it has been identified that the weekly demand is at most 6000 tons and4000 tons for bands and coils, respectively . The plant operates for a maximum of 40 hours per week. 1. In Microsoft Excel, formulate a linear programming model instance for this problem, then solve. 2. Assume that the products need to be painted after manufacturing, and the painting departmentcan paint at a rate of 600 tons per hour for bands and 400 tons per hour for coils. The paintingdepartment works only for 20 hours. Update the linear programming model instance to accom-modate this requirement, and re-solve the problem. 3.

For one flight segment, the average number of customers per day is 70, which represents a 65 percent utilization rate of the equipment assigned to the flight segment. If demand is expected to increase to 99 customers for this flight segment in three years, what capacity requirement should be planned? Assume that management deems that a capacity cushion of 20 percent is appropriate. The needed capacity requirement is [A] customers per day.
