Generalized production planning problem under interval uncertainty

Data in many real life engineering and economical problems suffer from inexactness.Herein we assume that we are given some intervals in which the data can simultaneously and independently perturb. We consider the generalized production planning problem with interval data. The interval data are in both of the objective function and constraints. The existing results concerning the qualitative and quantitative analysis of basic notions in parametric production planning problem.These notions are the set of feasible parameters, the solvability set and the stability set of the first kind.
