An economic ordering quantity (EOQ) is developed for the model incorporating items with ramp type demand, starting with shortage and two — parameter Weibull distribution deterioration.
Chadha proposed an algorithm for solving a linear fractional functional program when some of its constraints are homogeneous with a numerical example in support. The solution of the numerical example claimed by Chadha is not optimal. The correct optimal solution of the numerical example is given here.
In this paper a method is proposed to solve fractional programming problem in which the functional relationship between the decision variables and the objective function is not completely known. Here we established the crisp functional relationship between the objective function and the decision variables and solve the resulting programming problem to find a fair optimal solution to the original problem...
