Question

this is the Matlab answer : but i want the answer by using EES, USING Min/Max : so do same like is done here by matlab but by using EES:

The cost of a thermal system is given by the expression: C = (3.3x2 + 4y2) + (1400/x + 1500/y) where x and y are the sizes of two components. The terms within the first parentheses represent the capital costs and the terms within the second parentheses quantify the maintenance costs. Using any suitable optimization technique, calculate the values of x and y that optimize the cost. 'fminsearch' finds the minimum of a scalar function of several variables, starting at an initial estimate. This is generally referred to as unconstrained nonlinear optimization. the current x satisfies the termination criteria using OPTIONS. Tol X of 1.000000e-008 and F (X) satisfies the convergence criteria using OPTIONS. Tol Fun of 1.000000e-008

Explanation / Answer

Just write the equation in EES.

And then frm calculate menu choose option min/max and then select x and y as independent variables.

Then set the upper and lower bounds of x and y .

Then simply solve and u will get the answer.
