Simulating a structurally simple model of a manufacturing enterprise revealed complex dynamic behavior. Enterprise modeling and simulation provided estimates of end-of-life inventory and order delivery performance based on interactions of forecast quality, quoted product availability, material procurement and safety stock policies, vendor lead times, product life cycle, and part commonality. An...

The strategy of integration known as VMI (Vendor-Managed Inventory) allows the coordination of inventory policies between producers and buyers in supply chains. Based on a new proposed model for the implementation of VMI in a chain of two links composed of a producer and a buyer, this paper studies the evolution of individual strategies of the producer and the buyer by a formalism derived from ...

In this paper, production-inventory models for a deteriorating item in a single vendor-buyer system has been developed with constant production and demand rate. Shortages at the buyer (when it is allowed) depends on time. The models have been formulated as cost minimization problem via both integrated and non-integrated approaches and solved using genetic algorithms developed to solve the singl...

Vendor managed inventory (VMI) agreements are a supply chain collaboration principle in which the supplier is responsible for keeping at buyer between given lower and upper limits. VMI gives lot of autonomy while making replenishments, allowing to efficiently ensure availability buyer. But different suppliers may apply approaches staying limits under VMI. Relatedly, objectives not completely al...
