In this paper the author studies an optimization problem concerning a supply network consisting of a number of production and transportation facilities. Particularly the author starts from the consideration that in this context if each facility optimizes its own inventory independently, the result need not be optimal, in any sense, for the network as a whole. So he proposes an alternative model in which the cost of variability in the production rates is balanced against the cost of holding the inventories. The decision of what proportion of a variation in forecast demand should be met by immediate production, and what proportion taken from inventory, depends on certain parameters, describing feedback in a control system. The proposed control model is a linear model with two feedback parameters β and θ, whose values may be optimized. Only a fraction β of the forecast variation of production from a steady state is scheduled to be made, with inventory supplying any shortfall. Leonardo Pasini

Abstract
In this paper the author studies an optimization problem concerning a supply network consisting of a number of production and transportation facilities. Particularly the author starts from the consideration that in this context if each facility optimizes its own inventory independently, the result need not be optimal, in any sense, for the network as a whole. So he proposes an alternative model in which the cost of variability in the production rates is balanced against the cost of holding the inventories. The decision of what proportion of a variation in forecast demand should be met by immediate production, and what proportion taken from inventory, depends on certain parameters, describing feedback in a control system. The proposed control model is a linear model with two feedback parameters β and θ, whose values may be optimized. Only a fraction β of the forecast variation of production from a steady state is scheduled to be made, with inventory supplying any shortfall.
