Inventory management in the presence of inventory inaccuracies: an economic analysis by discrete-event simulation

Inventory inaccuracies in the wholesale supply chain

The inventory level shown in the Information System contrary to popular belief and assumptions in most academic papers and in spite of the considerable amounts invested in information technology, is often inaccurate. The inventory inaccuracy occurs when the inventory shown in the Information System is not in agreement with the actually available inventory. In this paper, we first describe the m...

USMC inventory control using optimization modeling and discrete event simulation

Stochastic Discrete-Time Model and Simulation of Inventory Management System

Inventory management plays a very important role in logistics system. This study presents a discrete-time model for regularly order inventory management system considering the randomicity of receiving goods of time and the volume of ordering determined by inventory difference. With the application of Simulink toolbox in MATLAB, an example of block diagram model in z-domain is built to simulate ...

Improving Product Availability in Hospitals: the Role of Inventory Inaccuracies

All players in the healthcare industry face increasing public and political pressure to improve quality of care and control costs. Hospitals, on the frontline of this challenge, face nursing shortages and financial constraints. Survey data indicate that missing medication and supplies interrupt nurses more than twice per shift, increasing costs and putting patients at risk. These challenges per...
