Davis Instruments has the difficulty in workforce scheduling. Recently Davis started hiring temporary workers supplied by WorkForce Unlimited, a company that specialized in providing temporary employees for firms. WorkForce Unlimited offered to provide temporary employees under two contract options that differ in terms of the length of employment and the cost. The two options are summarized as follows: Over the next six months. Davis proiects the followina needs for additional emplovees. - Davis's quality control program requires each temporary employee to receive training at the time of hire. The training program is required even if the person worked for Davis in the past. The cost of training is $700 for a temporary employee is hired on a contract of either one-month or three-month. To minimize the total cost, a) formulate the Davis' problem as a linear program by clearly defining decision variables, objective function, and constraints. Objective function, and constraints need to show the mathematical relationships (See the instruction above in red). b) develop an excel model for Davis to meet projected needs over the next six months.
