av A Haulin · 2014 — Abstract: A strategy for nuclear fuel bundle design optimization in boiling water reactors(BWRs), using a simplex method, is presented and 


The simplex method is an iterative process in which the Gaussian elimination is repeatedly applied to the coefficient matrix together with the constant column . In each iteration, one column of is selected to be converted to a standard basis vector to replace one of the previous standard basis vectors.

A more general method known as Simplex Method is suitable for solving linear programming problems with a larger number of variables. The method through an iterative process progressively approaches and ultimately reaches to the maximum.or minimum value of the obje ctive function.

It is an efficient algorithm (set of mechanical steps) that “toggles” through corner points until it has located the one that maximizes the objective  Use the simplex method to find an improved solution for the linear programming problem represented by the following tableau.
