The document contains two engineering economy questions. The first question asks about calculating the maximum amount to pay for a new manufacturing process that reduces production time and overhead costs per unit for a company that produces 8.7 million memory chips per year. The second question asks about calculating the total amount owed on a $900 loan with 10% annual interest over a 5 year term.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

1) A manufacturer makes 8,700,000 memory chips per year. Each
chip takes 0.4 minutes of direct labor at the rate of $9 per hour.
The overhead costs are estimated at $13 per direct labor hour. A
new process will reduce the unit production time by 0.05 minutes.
If the overhead cost will be reduced by $6.50 for each hour by
which total direct hours are reduced, what is the maximum amount
you will pay for the new process? Assume that the new process
must pay for itself by the end of the first year.
2) A man went to his bank and borrowed $900. He agreed to repay
the sum at the end of 5 years, together with the interest at 10% per
year. How much will he owe the bank at the end of 5 years?
