A Simulation Study Of Economic Production Quantity Lot Size To Kanban For A Single Line Production System Under Various Setup Times With Annual Setup Cost As Performance Metric

Optimal Setup Cost Reduction and Lot Sizing with Imperfect Production Processes and Quantity Discounts

OPTIMIZATION OF A PRODUCTION LOT SIZING PROBLEM WITH QUANTITY DISCOUNT

Dynamic lot sizing problem is one of the significant problem in industrial units and it has been considered by  many researchers. Considering the quantity discount in  purchasing cost is one of the important and practical assumptions in the field of inventory control models and it has been less focused in terms of stochastic version of dynamic lot sizing problem. In  this paper, stochastic dyn...

Optimal Lot Sizing and Setup Cost Reduction for Deteriorating Production System

In this paper, we extend Porteus (1986) to generalize the economic production quantity (EPQ) model with finite production rate and to derive an exact expression for the expected total annual cost function when maintenance actions and capital investment in setup cost reduction are adopted. In addition, the uniqueness property of the optimal lot size and the bounds of optimal lot size are derived...

New scheduling rules for a dynamic flexible flow line problem with sequence-dependent setup times

In the literature, the application of multi-objective dynamic scheduling problem and simple priority rules are widely studied. Although these rules are not efficient enough due to simplicity and lack of general insight, composite dispatching rules have a very suitable performance because they result from experiments. In this paper, a dynamic flexible flow line problem with sequence-dependent se...

A Capacitated Lot Sizing Problem with Stochastic Setup Times

In this paper, we study a Capacitated Lot Sizing Problem with Stochastic Setup Times (CLSP-SST).We describe a mathematical model that considers both regular costs (including production, setup and inventory holding costs) and expected overtime costs (related to the excess usage of capacity). The CLSP-SST is formulated as a two-stage stochastic programming problem. A procedure is proposed to effe...
