Please answer three questions:

a. find a level workforce plan that allows for no delay in service and minimizes undertime*. What is the total cost of this plan?

b.Use a chase strategy that varies the workforce level with minimal undertime and without using overtime. What is the total cost of this plan?

c.Propose a low-cost, mixed strategy and calculate its total cost. (Any strategy that improves on both the chase and level strategies is acceptable; no need to find the optimal schedule)

note: in each part, round the number of employees up to the nearest whole number. * Undertime is time paid, but without expectation of work output. For example, workers might get a Friday off with pay

2. Aggregate planning can be used in services, when there are no inventories. This question deals with such a situation. Kitty Forrest's golf camp estimates the following workforce requirements over the next two years: Quarter 1 4200 2 6400 3 3000 4 4800 5 4400 6 6240 7 3600 8 4800 Demand (hours) Each certified instructor puts in 480 hours per quarter regular time and can work up to 120 hours overtime. Regular-time wages and benefits cost Forrest $7200 per employee per quarter for regular time worked up to 480 hours, with an overtime cost of $20 per hour. Unused regular time for certified instructors is paid at $15 per hour. There is no cost for unused overtime capacity. The cost of hiring, training and certifying a new employee is $10,000. Layoff costs are $4000 per employee. There are currently 8 employees under contract. a. Find a level workforce plan that allows for no delay in service and minimizes undertime*.
