Chapter B, Problem 6P
Summary Introduction
To determine: The best production mix of yard gates using linear programming.
Introduction:
Linear programming:
It is a linear optimization technique followed to develop the best outcome for the linear programming problem. The outcome might be to maximize profit, minimize cost, or to determine the optimal product mix. The outcome will take the constraints present in achieving the solution into consideration.

The Carbondale Hospital is considering the purchase of a new ambulance. The decision will rest partly on the anticipated mileage to be driven next year. The miles driven during the past 5 years are as follows:
Year
Mileage

3,000
2
3
4
4,000
3,450
3,850

3,800
a) Using a 2-year moving average, the forecast for year 6 =
miles (round your response to the nearest whole number).
b) If a 2-year moving average is used to make the forecast, the MAD based on this = miles (round your response to one decimal place). (Hint: You will have only 3 years of matched data.)
c) The forecast for year 6 using a weighted 2-year moving average with weights of 0.40 and 0.60 (the weight of 0.60 is for the most recent period) = ☐ miles (round your response to the nearest whole number).

- Dyson, a high-tech home appliance maker, has cut ties with Malaysian supplier ATA IMS Bhd following an audit of the company's labour practices and allegations by a whistleblower. ATA is already under US investigation over forced labour allegations. Dyson has terminated its contracts and is in talks with its customer over the audit findings. ATA, which produces parts for Dyson's vacuum cleaners and air purifiers, tumbled 30% to its lowest since April 2020. The termination is a significant blow for Malaysia, a major electronics manufacturing hub, which has faced scrutiny this year over claims of abusive working and living conditions. Dyson terminated the relationship with six months' contractual notice, hoping it would give ATA the impetus to improve and enable an orderly withdrawal in the interests of the workers they employ. Former ATA worker Dhan Kumar Limbu was beaten by police in Malaysia after sharing information about conditions at the factory with activists. ATA denied all…arrow_forwardQuestion content area Part 1 Oakwood Hospital is considering using ABC analysis to classify laboratory SKUs into three categories: those that will be delivered daily from their supplier (Class A items), those that will be controlled using a continuous review system (B items), and those that will be held in a two bin system (C items).
