In this article we will discuss about:- 1. Concept of Inventory Control 2. Importance of Inventory Control 3.
Inventory also referred as stocks are basically the goods and raw materials that any business would hold and are ready or will be ready for sale. Inventory model is a mathematical model that helps business in determining the optimum level of inventories that should be maintained in a production process, managing frequency of ordering, deciding on quantity of goods or raw materials to be stored, tracking flow of supply of raw materials and goods to provide uninterrupted service to customers without any delay in delivery. Fixed Reorder Quantity System is an Inventory Model, where an alarm is raised immediately when the inventory level drops below a fixed quantity and new orders are raised to replenish the inventory to an optimum level based on the demand. The point at which the inventory is ordered for replenishment is termed as Reorder Point. The inventory quantity at Reorder Point is termed as Reorder Level and the quantity of new inventory ordered is referred as Order Quantity. Safety Stock S : It is the extra stock that is always maintained to mitigate any future risks arising due to stock-outs because of shortfall of raw materials or supply, breakdown in machine or plant, accidents, natural calamity or disaster, labour strike or any other crisis that may the stall the production process.
Harris Answers the question How much do I order? Used for independent demand items. Objective is to find order quantity Q that minimizes the total cost TC of managing inventory. Must be calculated separately for each SKU. Widely used.
In the company, materials inventory control system show the supply of materials repeatedly occurs but the demand of materials dependently on the rate of productions. Refer on this condition, statistic method used for materials inventory control, i. P and Q model. They are determines the quantity the time of ordering materials to minimize total inventory cost. The Q model parameter comprises of ordering materials quantity, ordering time, and buying price. On Q and P model application, the broken materials rate only depend on the weight of bowl and the shrink of materials weight, so it is important to investigate broken chemically pattern of materials when storage time. In addition, application of both models based on constant rate production capacity, so it is important too, to investigate materials inventory model if the company widened or production capacity increased.

Addressing the problems of a health care center which produces tailor-made clothes for specific people, the paper proposes a single product continuous review model and establishes an optimal policy for the center based on Q, r control policy to minimize expected average cost on an order cycle. A generic mathematical model to compute cost on real-time inventory level is developed to generate optimal order quantity under stochastic stock variation.

Orders delivered to U. Learn more. A fixed-order quantity system is one of the most important in inventory management. For that reason we need to look at how to compute the two variables that define it: the order quantity Q and the reorder point ROP. Before we do that, however, we need to look at the assumptions this system makes.
