A Replenishment Policy for Non-instantaneous Deteriorating Inventory System with Partial Backlogging

[[abstract]]This paper deals with the development of an inventory model for non-instantaneous deteriorating items. This paper investigates an instantaneous replenishment inventory model for the above type of items under cost minimization, considering stock-dependent consumption rate under inflation and time discounting over a finite planning horizon. In the proposed model, shortages are allowed and partially backlogged. We also show that the total cost function is convex. To determine the optimal order quantity and the optimal interval of the total cost function, a solution algorithm is presented. Finally, the model is illustrated with the help of numerical examples. Sensitivity analysis of the optimal solution with respect to various parameters of the system is carried out and the results are discussed in detail

Abrasive water jet machining of fiber-reinforced composite materials

Composite materials have taken an imperative place in the material system because of their unique performance in various specialized applications. Fiber inclusion and the heterogeneous property of composites make it more difficult to machine with the conventional machining process. However, several nonconventional methods have been adopted for machining composites, in which abrasive water jet machining (AWJM) was proven to be more effective and a preferable technique in machining of fiber-reinforced composite material. This review article is intended to highlight and categorize the machining performance of the fiber-reinforced composites on machining with AWJM process. </jats:p
