Modelos de sistemas MRP cerrados integrando incertidumbre

Arango-Serna, Martín Darío | 2013-11-06

In this paper, we present four models of uncertainty in the MRP closed systems in the production components, such as: manufacturing capacity of each product, delivery time and inventory availability. These parameters are processed by the fuzzy logic by modeling an MRP closed system deterministic. Therefore, three models are initially MRP closed system, where each independently consider uncertain ty in capacity, delivery time and inventory availability. Also, we present a fourth model of MRP closed system jointly analyzes the uncertainty in the three parameters mentioned above. Each of these models is corroborated with information from a company in the Colombian electricity area, evaluating the total cost of the production plan, inventory levels, service level and computational complexity.
