A hоspitаl divisiоn cоnsists of three lаrge nursing units, A, B, аnd C. The registered nurses (RN’s) in units A, B, and C earn $30, $27, and $24 per hour, respectively. Overtime is paid at double time. There is also the possibility of assigning some of the hours from nurses assigned to unit A to meet requirements in unit B, as well as the possibility of assigning some of the hours from nurses assigned to unit B to meet requirements in unit C. The division wants to develop a 4-month staffing plan. The minimum number of labor hours required in each unit each month are: January February March April Unit A 2700 2300 2100 2600 Unit B 2400 2800 2900 2200 Unit C 2100 2600 2300 2400 The number of regular-time hours allocated for any individual unit should be the same in each of the 4 months (e.g., the number of regular-time hours assigned for A in January must be the same number in A for Feb, March, and April). Overtime can be used as needed in any unit but cannot exceed 18% of regular-time hours in the unit in any month. In any given month, up to 15% of the total number of regular-time plus overtime hours available from nurses assigned to unit A can be used to meet nursing requirements in unit B. Likewise, in any given month, up to 15% of the total number of regular-time plus overtime hours available from nurses assigned to unit B can be used to meet nursing requirements in unit C. Develop a linear programming formulation that will determine the assignment of regular-time and overtime nursing hours to each nursing unit each month. The objective of the model is to minimize total staffing costs for the division during the 4-month period. Constraints of the model should guarantee that nursing hours meet or exceed the labor hours required in each unit each month, and that the overtime and substitution (i.e., using hours assigned to A to meet requirements in B and/or hours assigned to B to meet requirements in C) conditions are satisfied
