EOQ formula when inventory cost is fuzzy

Article Abstract:

The use of fuzzy sets for characterizing uncertain cost parameters in inventory models was investigated. Specifically, the approach, which may be implemented in four ways, was applied to the problem of determining the optimal economic order quantity with fuzzy ordering and holding costs. It may be implemented by fuzzifying the EOQ formula, by computing fuzzy cost values and minimizing the defuzzified values, or by calculating fuzzy cost values and minimizing them.

Supply chain modelling using fuzzy sets

Article Abstract:

A study was conducted to analyze a production supply chain supporting facilities in a serial connection. The supply chain includes production facilities and inventories between them. Uncertainty was correlated with supply delivers along the supply chain, customer demand and market supply. In addition, simulation tests were carried out to evaluate the influence of uncertain external supply on the service level of the supply chain.
