Abstract

The objective of this project is the design of an inventory control system for the arthroscopy line at Bioart SA, born of the need to eliminate overcharges in the inventory and its processes, customer complaints and the loss of sales in arthroscopy for lack of control of the stocks of their products. For its elaboration it was first diagnosed the current form of supply of the company to identify the publications and the weaknesses, after an analysis ABC was identified the products that present a greater participation in the sales of the company and that generate a major negative impact if there is no availability of the product, based on these and taking the data of the sales of the years 2015 and 2016 given by the company, it was determine the behavior of the demand with the application of the coefficient of variation, resulting in the base to the choice of appropriate forecasting methods for each item. Analyzing the patterns of demand, inventory models were identified that are suitable for the products, resulting in the EOQ model for products with uniform demand and the POQ model for products with increasing or decreasing demand. Excel templates were made that allow the company to know the quantity per order depending on each model. In order to have a better control of the inventory, the sales data and delivery times given by the company were taken and the security inventory and the reorder point were determined for each type item and for items type B and C with higher share of sales. Subsequently, the inventory control model is complemented by indicators that allow the evaluation of inventory compliance and lastly the value of the cost-benefit ratio to recognize the long-term gain of the proposed inventory model.
