An experience-based system supporting inventory planning: A fuzzy approach

• Suphattra Ketsarapong, Varathorn Punyangarm, Kongkiti Phusavat, Binshan Lin
• Expert Syst. Appl.
• 2012

The study aims to extend the Uncapacitated Fuzzy Single Item Lot Sizing Problem (known as F-USILSP) model and extend it for inventory planning. The F-USILSP model is a good choice when there is no… (More)

A Credibility Approach for Fuzzy Stochastic Data Envelopment Analysis ( FSDEA )

• Varathorn Punyangarm, P. Charnsethikul
• 2006

It is well known that Data Envelopment Analysis (DEA) is a relative efficiency measurement tool, which uses optimization techniques to automatically calculate the weights assigned to the crisp… (More)

The Chance-Constrained Programming for the Lot-Sizing Problem with Stochastic Demand on Parallel Machines

• Supatchaya Chotayakul, Varathorn Punyangarm

POSSIBILITY APPROACH FOR SOLVE THE DATA ENVELOPMENT ANALYTICAL HIERARCHY PROCESS ( DEAHP ) WITH FUZZY JUDGMENT SCALES

• Varathorn Punyangarm
• 2010

The data envelopment analytical hierarchy process (DEAHP) is a type of the analytical hierarchy process (AHP), which used the concept of data envelopment analysis (DEA) for generating LW from the… (More)

An MIP-based heuristic approach to determine production lot size for capacitated single-stage production processes with stochastic demand on parallel machines

• Supatchaya Chotayakul, Varathorn Punyangarm
• 2017 6th International Conference on Industrial…
• 2017

This paper deals with the capacitated single-stage production lot sizing and scheduling problem with multiple items, setup time, stochastic demand and unrelated parallel machines. A stochastic… (More)
