WC company is the worlds largest manufactuer of ambulances had only a handful of employees while beginning. It is like many other companies did not build the manufacturing plant from scratch.
Since the plant is not built from scratch there are some issues where too many employees are running into each other in the assembly line. It has become increasingly difficult to finish an ambulance in seven days.
To measure: The efficiency of this layout.

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.
