Multi-item inventory model with probabilistic price dependent demand and imprecise goal and constraints

A multi-item single-period stochastic inventory model is formulated in the fuzzy environment with budgetary, floor-space constraints. In this model, probabilistic demand is related to the unit selling price. Here fuzziness is introduced in both the objective function and constraint goals. The problem is solved using the fuzzy nonlinear technique for linear membership functions. The model is illustrated numerically and sensitivity analysis is presented. The numerical results are compared with those of the crisp model.
