(a) How many Spanish-speaking operators and how many Englishspeaking operators does the hospital need to staff the call center during each 2-hour shift of the day in order to answer allcalls? Please provide an integer number since half a human operator makes no sense.(b) Lenny needs to determine how many full-time employees whospeak Spanish, full-time employees who speak English, and parttime employees he should hire to begin on each shift. CreativeChaos Consultants advise him that linear programming can beused to do this in such a way as to minimize operating costswhile answering all calls. Formulate a linear programmingmodel of this problem.(c) Obtain an optimal solution for the linear programming modelformulated in part (b) to guide Lenny’s decision.(d) Because many full-time workers do not want to work late into theevening, Lenny can find only one qualified English-speaking operator willing to begin work at 1 P.M. Given this new constraint,how many full-time English-speaking operators, full-time Spanishspeaking operators, and part-time operators should Lenny hire foreach shift to minimize operating costs while answering all calls?(e) Lenny now has decided to investigate the option of hiring bilingual operators instead of monolingual operators. If all the operators are bilingual, how many operators should be workingduring each 2-hour shift to answer all phone calls? As in part(a), please provide an integer answer.(f) If all employees are bilingual, how many full-time and part-timeemployees should Lenny hire to begin on each shift to minimizeoperating costs while answering all calls? As in part (b), formulate a linear programming model to guide Lenny’s decision.(g) What is the maximum percentage increase in the hourly wagerate that Lenny can pay bilingual employees over monolingualemployees without increasing the total operating costs?(h) What other features of the call center should Lenny explore toimprove service or minimize operating costs?
