Our incentive is to assess the impact of demand forecast errors on the cost performance of several lot-sizing techniques in a multi-level context. Unpredicted changes in demand keep on plaguing consumer product companies. However, efforts to improve demand forecast accuracy may not be rewarded...

We consider the multi-level lot-sizing problem in a rolling-schedule environment as it occurs in Material Requirements Planning systems, with no capacity constraints and a time-invariant cost structure. We show that the performance of fixed-horizon methods can be improved drastically in a...

Over the last decade new manufacturing methods and techniques have focused on reducing waste in production tasks. Just-In-Time (JIT) manufacturing is one of the most popular new technologies adopted. This dissertation describes the impact of Just-In-Time manufacturing on firm value, product...

On the basis of the recent concepts of epistemic communities and communities of practice, we show that the firm can be defined according to a form of double duality: cognitive and organisational. The interest of this approach is to put ahead the differentiated behavior from the manager and the...

This paper addresses the question of organization of work and efficient reorganization. An emerging literature is basically concerned with the polar model of high involvement (holistic) vs. traditional (Tayloristic) work organizations. This paper extends in two ways: First, the polar case is...

The objective of the paper is to confront the conclusions in the seminal papers of Lindbeck and Snower (2001, 2000, 1996) and Snower (1998) with the empirical evidence in the manufacturing sector, thus testing the from-Tayloristic-to-holistic-organization model. Starting from stylized facts as...

The paper analyzes voluntary Free Software/Open Source Software (FS/OSS) organization of work. The empirical setting considered is the Debian GNU/Linux operating system. The paper finds that the production process is hierarchical notwithstanding the modular (nearly decomposable) architecture of...

About inventory models, a concern is 'often made [that] any resemblances between the models constructed and reality are purely coincidental.' One set of factors not usually considered in textbook models of inventory decisions is suggested by well-documented evidence in macroeconomics, that the...
