At a medium-sized Family Practice, the process flow is as follows: Medical Profile Update Processing Time: 4 min/unit #Employees: 5 Sign In Insurance Check (Vitals by Nurse Physician Consult Processing Time: 2 min/unit # Employees: 1 Processing Time: 6 min/unit # Employees: 3 Processing Time: 8 min/unit # Nurses: 4 Processing Time: 20 min/unit # Physicians: 4 Retrieve Lab Reports Processing Time: 1 min/unit #Employees: 1 The Practice see two types of patients every day: Existing (90% of total) and New (10% of total). The process is largely the same for both types of patients, except that Lab Reports need to be retrieved for only for existing patients. The practice is open for eight hours per day, five days a week. After signing in, three steps are done in parallel for existing patients, and two steps for new patients. The patients then get seen by the Nurse followed by the physician. For each step, the processing time and the number of employees is given. There is no uncertainty in this problem. The following parts (a) - (g) are based on this description. 1) If the system is capacity constrained, what is the utilization for the "Sign In" process? 2) Suppose (only for this part) that the Retrieve Lab Reports has a setup time of 4 minutes, rather than 0 minutes as we assumed above. Because of this setup time, you retrieve reports in batches of 2. How does the capacity of the Retrieve Lab Reports stage change due to this new information? 1 3) Again, suppose this is a capacity constrained system. Suppose the variable cost of each service is $150 for existing patients and $200 for new patients, the revenue from each service is $250, and the fixed costs are $400/hour. What is the profit/hour of the Family Practice?
