Determining the economic lot size has always represented one of the most important issues
in production planning. This problem has long attracted the attention of researchers, and …

This paper considers an economic production quantity (EPQ) model with imperfect
production processes, in which the setup cost and process quality are functions of capital …

While the net present value (NPV) approach is widely accepted as the right framework for
studying production and inventory control systems, average cost (AC) models are more …

The basic assumption of the conventional inventory models is that all items produced are of
perfect quality. In practice, some defective items are produced due to process deterioration …

This paper analyzes a two-product system with joint manufacturing and remanufacturing. In
such a system the end-product stock contains both manufactured and remanufactured …

The set-up cost and yield variability are given and fixed in existing production/inventory
models with random yields. However, in many practical situations, they can be reduced by …

We use a quasi-natural experiment based on the 2005 Domestic Production Activities
Deduction (DPAD) to test whether the benefits of tax incentives for domestic production are …

Holding costs are traditionally determined from the investment in physical stock during a
cycle. An alternative approach instead derives holding costs from Net Present Value (NPV) …

While the net present value (NPV) approach is widely accepted as the right framework for
studying production and inventory control systems, average cost (AC) models are more …

The purpose of this paper is to investigate and propose a fuzzy extended economic
production quantity model based on an elaboratively modeled unit cost structure. This unit …
