Thread: How to choose the best from two variables?

I have to develop a mathematics model to choose the best from two variables...


for example:
there is five fruit stall in town and each stall sell orange, apple and grape. The price for each fruit is different for each stall. I have to consider the fruit with lowest price which is my 1st choice is apple, 2nd is orange and 3rd is grape...


should I use goal programming or there is another easier or proper method to use?
can anyone give the best method with a brief explanation...thanks in advance




-sorry for my English-

Your English is excellent- far better than my (put whatever language you like here!).

But to decide which is "best" you need to specify some kind of "value" function. Because there are three fruits involved here, you probably want a "weighted average" with the weights determined by which fruit you liked best.

thanks
