Case Problem
Mr Shyam Prasad, recently transferred to Chennai from Lucknow, has to choose a school for his two children. He has three choices of the school and it is likely that his children would be allotted one of them. Shyam Prasad has chosen his best 3 schools (A, B, C) and wishes to rank them. He would be happy if the children get either the first or the second choice.
Case Facts

Additional Case Facts
Mr Prasad believes in a linear relationship among the input and output parameters and wishes to rank them based on their efficiencies.
Efficiency for each school is defined as Ratio of Weighted Output to Weighted Input.
The weights to the input & output are the decision variables.
Each school should assign weights such as to maximize its efficiency, subject to the condition that for the defined weights no school has efficiency exceeding 1.
The efficiency is a fraction and by defining the input to 1, we can convert the problem
