Consider a town with three Health Centre - HA, HB and HC. The state wants to see the efficiency of these Health Centres. They identified two inputs, which are number of doctors and number of nurses and outputs, namely number of discharges and number of operations. The input and output values for each health care centre are as follows: Health Centre HA HB HC Inputs Doctor 3 4 5 Nurse 8 7 4 Outputs Discharge 1000 400 200 Operation 20 50 150 Formulate an LP model for this data envelopment analysis to determine whether health centre HC is efficient as compared to other health centres.

Five factors appear to be related to regional sales: the number of retail outlets in the region, the number of automobiles in the region registered as of April 1, the total personal income recorded in the first quarter of the year, the average age of the automobiles (years), and the number of sales supervisors in the region. The data for each region were gathered for last year. For example, see the following table. In region 1 there were 1,739 retail outlets stocking the company’s automotive parts, there were 9,270,000 registered automobiles in the region as of April 1, and so on. The region’s sales for that year were $37,702,000. constant outlet automobile reg income age bosses 37.702 1,739 9.27 85.4 3.5 9 24.196 1,221 5.86 60.7 5 5 32.055 1,846 8.81 68.1 4.4 7 3.611 120 3.81 20.2 4 5 17.625 1,096 10.31 33.8 3.5 7 45.919 2,290 11.62 95.1…For unemployed persons in the United States, the average number of months ofunemployment at the end of December 2009 was approximately seven months(Bureau of Labor Statistics, January 2010).
