Optimization of Economic Production Quantity and Profits under Markovian Demand
"... Abstract--- In most manufacturing industries; demand uncertainty affects effective planning and control of production levels that maximize profits. In this paper, a new mathematical model is developed to optimize economic production quantity (EPQ) of a single-item, finite horizon, periodic review in ..."

Coordinating production quantities and demand forecasts through penalty schemes
- IEE Transactions
, 1999
"... In this paper, we study coordination mechanisms through penalty schemes between manufacturing and marketing departments which enable organizations to match demand forecasts with production quantities. This research was motivated by our interactions with a leading electronics and computer manufacture ..."

FUZZY ECONOMIC PRODUCTION QUANTITY MODEL FOR ITEMS WITH IMPERFECT QUALITY
, 2006
"... Abstract. In the real world, vague phenomenon is quite common in the production/inventory models. In order to process the vagueness, a production/inventory model that can be more closely related to the real vagueness and can take account of the vague factors that contribute to production costs, is r ..."

Quantity (FEPQ) model with imperfect products that can be sold at a discount price. In this model, costs and quantities are expressed as trapezoidal fuzzy numbers. Moreover, we use Function Principle to manipulate arithmetical operations, Graded Mean Integration Representation method to defuzzify, and Kuhn
Economic Production Quantity in Reworkable Production Systems with Inspection Errors, Scraps and Backlogging
, 2009
"... ABSTRACT The classical economic production quantity (EPQ) model is a well-known and commonly used inventory control technique. Common assumptions in this model are that all units produced are of perfect quality and shortage is not allowed, since in practice shortage, non-conforming product or scrap ..."

ECONOMIC PRODUCTION QUANTITY CONCERNING LEARNING AND THE REWORKING OF IMPERFECT ITEMS
, 2009
"... Abstract: The classical economic production quantity (EPQ) model assumes that items produced are of perfect quality and the production rate is constant. However, production quality depends on the condition of the process. Due to process deterioration or other factors, the production process may shif ..."

Instrumental Variables and the Search for Identification: From Supply and Demand to Natural Experiments
- Journal of Economic Perspectives
, 2001
"... The method of instrumental variables is a signature technique in the econometrics toolkit. The canonical example, and earliest applications, of instrumental variables involved attempts to estimate demand and supply curves. 1 Economists such as P.G. Wright, Henry Schultz, Elmer Working and Ragnar Fri ..."

Frisch were interested in estimating the elasticities of demand and supply for products ranging from herring to butter, usually with time series data. If the demand and supply curves shift over time, the observed data on quantities and prices reflect a set of equilibrium points on both curves
The Economic Production Quantity Problem with a Finite Production Rate and Fuzzy Cycle Time
, 2008
"... Managing the inventories along with carrying out the production program is essential for many companies in the producing industry. In this paper, a fuzzy EPQ (Economic Production Quantity) model is developed to address this specific problem as a theoretical study. However, this problem derives from ..."

A New Approach to Economic Production Quantity Problems with Fuzzy Parameters and Inventory Constraint
"... Abstract. In this paper, we will develop a new multi-item economic production quantity model with limited storage space. This new model will then be extended to allow for fuzzy demand and solved numerically with a non-linear programming solver for two cases: in the first case the optimization probl ..."

Stochastic Multi-Item Inventory Systems with Markov-Modulated Demands and Production Quantity Requirements
"... Abstract We study a multi-item two-stage production system subject to Markov-modulated demands and production quantity requirements. The demand distribution for each item in each period is governed by a discrete Markov chain. The products are manufactured in two stages. In the first stage, a common ..."
