We consider a manufacturing system with stochastic demand and predictable production yield. The manufacturer has predetermined prices and limited production capacity in each period. The manufacturer also has the option to save some inventory for future periods even if there is demand in the current period. The demand that is not met is lost or may be backordered for only one period. Our objective is to maximize the expected profit by choosing optimal produce-up-to level ((Y) over bar*(t)), save (S*(t)) and backorder quantities (B*(t)) in each period t. We formulate this problem as a Markov Decision Process where the state of the system is represented by the net inventory and the yield rate. We show that a modified order-up-to policy ((Y) over bar*(t),S*(t),B*(t)) is optimal in each period t. We also perform computational analysis to examine the effects of production yield on the optimal decisions.

Tactical inventory and backorder decisions for systems with predictable production yield Mart, Turgut; Duran, Serhan; Department of Industrial Engineering (2010) We consider a manufacturing system with stochastic demand and predictable production yield. The manufacturer has predetermined prices and limited production capacity in each period. The producer also has the option to save some inventory for future periods even if there is demand in the current period. The demand that is not met is lost or may be backordered for only one period. Our objective is to maximize the expected profit by choosing optimal production, save and backorder quantities in each period. We ...
Optimization of the lubricating oil inventory policy applied in a mining company Şenses, Sena; Gölbaşı, Onur; Bakal, İsmail Serdar (2021-02-01) The mining industry should sustain mass and continuous production with an essential contribution of high-capacity machinery. Therefore, spare parts inventory management is vital in ensuring the intended mining production rate as an integral part of maintenance policies. In this paper, a mixed-integer model is presented to solve a multi-item and multi-supplier spare parts inventory model. This model is addressed to a lubricating oil inventory problem in one of the biggest multi-process mining companies in Tu...
Nonlinear and dynamic programming models for an inventory problem in a partially observable environment Darendeliler, Alp; Serin, Yaşar Yasemin; Department of Industrial Engineering (2016) In this study, a single-item periodic-review inventory system is considered in a partially observable environment with finite capacity, random yield and Markov modulated demand and supply processes for finite-horizon. The exact state of the real process, which determines the distribution of the demand and supply, is unobservable so the decisions must be made according to the limited observations called observed process. Partially Observable Markov Decision Process is used to model this problem. As an altern...
Optimal Mechanisms to Match Supply and Demand in Contemporary Supply Chains (OPTCHAIN) Merzifonluoğlu, Yasemin(2016-2-07) Emerging production and information technologies have increased competition and consumer expectations, this leads to ever-shrinking product life cycles, volatile and unpredictable markets. In addition, natural disasters, accidents, supply disruptions increased the risk in today’s global and long supply chains. Keeping costs down and customers satisfied in a global marketplace requires companies to proactively manage supply and demand using state of art techniques, technologies and practices. This proposal d...
Quantity Flexibility for Multiple Products in a Decentralized Supply Chain Bakal, İsmail Serdar (2010-09-03) One of the major complicating factors in decentralized supply chains is the long procurement/manufacturing lead times, which forces the upstream members to commit resources to production based on forecasted demand. Downstream members (the retailer for the rest of the manuscript) would like to have a higher production quantity to be able to satisfy the demand whereas upstream members (the manufacturer for the rest of the manuscript) would like to have some sort of assurance about the demand so that they will...
