Question: California Children s Hospital currently uses a confusing decentralized appointment and
California Children’s Hospital currently uses a confusing, decentralized appointment and registration process for its patients. Therefore, the decision has been made to centralize the process by establishing one call center devoted exclusively to appointments and registration. The hospital manager now needs to develop a plan for how many employees of each kind (full-time or part-time, English speaking, Spanish speaking, or bilingual) should be hired for each of several possible work shifts. Linear programming is needed to find a plan that minimizes the total cost of providing a satisfactory level of service throughout the 14 hours that the call center will be open each weekday. The model requires more than two decision variables, so a software package such as described in Sec. 3.5 or Sec. 3.6 will be needed to solve the two versions of the model.
