Each certified instructor puts in $480$ hours per quarter regular time and can work an additional $120$

hours overtime. Regular$-$time wages and benefits cost Carlton $$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$ dollars 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.

Currently, eight employees work in this capacity.

a$.$ Find a workforce plan using a level$-$utilization strategy 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 without using overtime or undertime. What

is the total cost of this plan?

c$.$ Propose a low$-$cost$,$ mixed$-$strategy plan and calculate its total cost.

GOLF CAMP II

Now assume that Carlton is permitted to employ some uncertified, part$-$time instructors,

provided they represent no more than $15$ percent of the total workforce in any quarter. Each

part$-$time instructor can work up to $240$ hours per quarter, with no overtime or undertime cost.

Labor costs for part$-$time instructors are $$12$ per hour. Hiring and training costs are $$2000$ per

uncertified instructor, and there are no layoff costs.

a$.$ Propose a low$-$cost$,$ mixed$-$strategy plan and calculate its total cost.

b$.$ What are the primary advantages and disadvantages of having a workforce consisting of

both regular and temporary employees?
