In this paper, sliding mode control of inventory management systems is considered. A new method of sliding hyperplane selection for these systems is proposed. The method utilizes the state matrix in the so called Frobenius form in order to simplify the selection process of the sliding variable. In contrast to most conventional approaches, the sliding variables considered in this work can have any...
In this paper a new dead-beat sliding mode warehouse management strategy is proposed. The strategy ensures full customers' demand satisfaction and prevents from exceeding the warehouse capacity. Furthermore, it ensures that the ordered quantities of goods are always non-negative and upper bounded. The proposed strategy not only explicitly takes into account decay of goods stored in the warehouse (perishing...
In this paper, we apply control-theoretic approach to the design of inventory policy for systems with perishable goods. In the considered systems, the stock used to fulfill unknown, variable demand is subject to exponential decay. It is replenished from multiple supply sources characterized by different lead times. The challenge is to achieve high demand satisfaction with minimum costs when replenishment...
In this paper we address the problem of efficient control of periodic-review perishable inventory systems. In the considered systems the stock used to fulfill unknown, variable demand deteriorates exponentially, and is replenished with delay from several supply sources. The supply options are characterized by different lead times, spanning multiple review periods. We develop a new supply policy based...
