Case: Workforce Scheduling Renova has two manufacturing sites located in Australia. Renova faces difficulty in workforce scheduling as product demand fluctuates considerably from month to month. To address this issue, Renova started hiring temporary workers supplied by BK, a company that specialises in providing temporary employees for firms in Australia. BK offered to provide temporary employees under three contract options that differ in terms of the length of employment and the cost. The three options are summarised: Option Length of Employment Cost 1 $1800 2 One Month Two Months Three Months $4000 $6200 3 The longer contract periods are more expensive because BK experiences greater difficulty finding temporary workers who are willing to commit to longer work assignments. Over the next six months, Renova projects the following needs for additional employees: Month January February March April May June Employee Expected 15 10 5 32 25 10 Each month, Renova can hire as many temporary employees as needed under each of the three options. For instance, if Renova hires five employees in January under Option 2, BK will supply Renova with five temporary workers who will work for two months: January and February. For these workers, Renova will have to pay 5($4000) = $20,000. Because of some merger negotiations under way, Renova does not want to commit to any contractual obligations for temporary employees that extend beyond June. Renova's quality control program requires each employee to receive training at the time of hire. The training program is required even if the person worked for Renova in the past. Renova estimates that the cost of training is $700 each time an employee is hired. Thus, if an employee is hired for one month, Renova will incur a training cost of $700, but will incur no additional training cost if the employee is on a two- or three-month contract. Training cost is incurred when an employee (temporary or full-time) is hired. 2.
