Note on solving inventory models from operational research view

Abstract

In this article, we will show that an optimal solution can be derived without complicated mathematical derivation, an improvement on the paper [Yang, G.K., et al., 2011. Note on inventory models with Weibull distribution deterioration. Production Planning & Control, 22 (4), 437–444] that was recently published in Production Planning & Control. We extend their inventory model with a generalised deterioration and backlog rates. Our findings will allow researchers to consider inventory models directly from the view of operational research instead of complex analysis.

Keywords:

• inventory
• Weibull distribution
• partially backlogging
