Adaptive Control of a Two-Item Inventory Model with Unknown Demand Rate Coefficients
This paper considers a multiitem inventory model with unknown demand rate coefficients. An adaptive control approach with a nonlinear feedback is applied to track the output of the system toward the inventory goal level. The Lyapunov technique is used to prove the asymptotic stability of the adaptive controlled system. Also, the updating rules of the unknown demand rate coefficients are derived...
متن کاملDynamic Inventory Planning with Unknown Costs and Stochastic Demand
Generally ordering policies are done by two methods, including fix order quantity (FOQ) and fix order period (FOP). These methods are static and either the quantity of ordering or the procedure of ordering is fixing in throughout time horizon. In real environments, demand is varying in any period and may be considered as uncertainty. When demand is variable in any period, the traditional and st...
متن کاملpresenting a new model for inventory control of multi-item economic production quantity (epq) with fuzzy random demand
inventory control problem is one of the problems in decision making and management that contains non-crisp parameters in real world. economic production quantity (epq) model in fuzzy environment has been studied so far by many researchers. one of the main assumptions in all previous researches was neglecting the inventory shortage. in this research, a new multi-item epq model with fuzzy random ...
متن کاملA Deteriorating Two-Item Inventory Model with Continuously Decreasing Demand and Retroactive Holding Cost
Demand correlation among two interacting items is common in real-life markets. Sometimes demand of the first item would trigger additional demand toward the second item, but not vice versa. For items with decreasing demand in time, the longer is the selling period, the less the demand and the higher the inventory cost. This paper develops the related inventory model during which two deteriorati...
متن کاملFuzzy adaptive tracking control for a class of nonlinearly parameterized systems with unknown control directions
This paper addresses the problem of adaptive fuzzy tracking control for aclass of nonlinearly parameterized systems with unknown control directions.In this paper, the nonlinearly parameterized functions are lumped into the unknown continuous functionswhich can be approximated by using the fuzzy logic systems (FLS) in Mamdani type. Then, the Nussbaum-type function is used to de...
