Abstract Learning has become essential for many companies whose manufacturing environment, where tasks have increased in complexity, requires a workforce of specific skills. Training of workers and learning-by-doing reduce the unit cost as the production rate speeds and improve product and process quality. Better quality means less rework and machine

Energy considerations for the economic production quantity and the joint economic lot sizing
Journal of Business Economics, 2019The increased awareness on sustainability, along with several governments’ actions for setting greenhouse gas restrictions, has recently generated a relevant pressure on industries towards the improvement of environmental performances. Among the several aspects, companies’ focus is mainly on energy use, firstly for its relevant and direct impact on the

AN ECONOMIC PRODUCTION QUANTITY MODEL WITH LEARNING AND FORGETTING CONSIDERATIONS
Production and Operations Management, 1994The focus of this work is on the effects of learning on economic production quantity in batch production systems. We assumed that both unit variable manufacturing time and setup time follow a learning curve. We modified the classical Economic Production Quantity model to incorporate these two types of learning phenomena.

The economic production quantity (EPQ) with shortage derived algebraically
International Journal of Production Economics, 2001Abstract Previously, in several papers and textbooks, the classical economic order quantity (EOQ) and the economic production quantity (EPQ) formulas for the shortage case, have been derived using differential calculus and solving two simultaneous equations (derived from setting the two first partial derivatives to zero) with the need to prove ...

Abstract This paper studies the materials procurement decision-making based on the economic order quantity model and the economic production quantity model. The make-or-buy decision makings are common to all manufacturing firms. Three terms composing the total cost per unit time are analyzed; they are annual setup cost, annual purchase cost, and annual

International Journal of Computer Applications in Technology, 2003
In this paper, we consider the problem of determining the production rate, production batch size, and production sequence when production rate, setup cost, and unit processing cost are sequence-dependent. Using a standard lot sizing model with backorder, a tabu search algorithm for solving this problem is proposed.

Setup Reduction in the Economic Production Quantity Model
Decision Sciences, 1992ABSTRACTWe present an analysis of setup cost reduction using the economic production quantity model. The objectives of the paper are to draw conclusions by investigating several classes of setup reduction functions and to provide a general solution procedure.
