Production planning in reconfigurable enterprises and reconfigurable production systems

2005

Reconfigurable enterprises and reconfigurable production systems represent nowadays one of the key responses towards the organisational and manufacturing needs arising in the new era known as mass customization. The paper proposes an Agent Based approach for the production planning activities in reconfigurable enterprises, characterized by complex, articulated and geographically distributed production capacities contended by many product families and composed by reconfigurable production systems that allow quick adjustment of production capacity and functionality consenting to manufacture different products of the same part family.

High Level Planning of Reconfigurable Enterprises: a Game Theoretic Approach

2006

Reconfigurable Enterprises (REs) represent production networks made of different and geographically dispersed plants that, in case of unpredictable market changes, can be reconfigured in order to gather a specific production objective. However, REs effectiveness and efficiency depend on the extent to which global performance is obtained. Basically two approaches are available to reach coordination: centralised or decentralised planning tools. In this paper, the authors propose a novel cooperative game theoretical approach for distributed production planning at high level of a RE; the proposed approach has been benchmarked in front of both a distributed one, based on negotiation, and a centr…

Does FDI in China Displace Foreign Jobs in Asia?

2014

This paper studies the China effect from a novel perspective. We focus on the effect of FDI in China on foreign employment flows in the rest of Asia. The concentration of FDI in China may divert employment from similar surrounding countries. Offsetting this negative effect, MNE activities might spillover to neighboring countries along the foreign production chain. Therefore, the effect of global FDI champions is uncertain. Most studies on this issue focus on trade and FDI inflows. The China effect on other aspects of international production, like employment, remains largely unknown. The contributions of this paper are twofold. First, we enhance the estimation of the China effect with recen…

A user-friendly control system to easy reconfigure a manufacturing cell

2006

Generic manufacturing enterprises need to interact with an environment characterized by a strong competition. In order to react to the mutable requests of market, control systems should confer to the manufacturing system capabilities for easy modifiability, and this can be achieved by reducing the necessary time to reconfigure the existing system. Following this main requirement, this paper presents a user-friendly control system that pursues three operational goals: - Ability to easy re-program the sequence of operations of the manufacturing equipments of a manufacturing cell; - Reconfigurability of the system, by allowing to add/remove a new/existing component in/from the manufacturing ce…

Why Bring Organic and Molecular Electronics to Spintronics

2015

Organic spintronics field is an emerging field at the frontier between organic chemistry and spintronics. Exploiting the peculiarity of these two fields, it combines the flexibility, versatility and low production cost of organic materials with the nonvolatility, spin degree of freedom and beyond CMOS capabilities offered by spintronics. Before starting the discussion on the organic spintronics field, in this chapter will be provided a brief introduction on organic and molecular electronics and the specificities of molecules. This will help to understand the advantages that molecular systems can bring to spintronics.

HOLONIC PRODUCTION SYSTEM TO OBTAIN FLEXIBILITY FOR CUSTOMER SATISFACTION

2008

The Holonic Production System (HPS) can be a valid choice to overcome the problems of traditional production sys-tems’ architectures, thanks to its capability to adapt and react to changes in the business environment whilst being able to maintain systemic synergies and coordination. The HPS is made of holons seen as functional production units which are simultaneously autonomous and cooperative. Although the holonic approach could represent a valid solution in order to pursue the necessary levels of agility of production systems, they have been scarcely implemented in practice and even less studied from a business studies perspective. The purpose of this discussion paper is to show the bene…

Optimization of Long-Run Average-Flow Cost in Networks With Time-Varying Unknown Demand

2010

We consider continuous-time robust network flows with capacity constraints and unknown but bounded time-varying demand. The problem of interest is to design a control strategy off-line with no knowledge of the demand realization. Such a control strategy regulates the flow on-line as a function of the realized demand. We address both the case of systems without and with buffers. The main novelty in this work is that we consider a convex cost which is a function of the long-run average-flow and average-demand. We distinguish a worst-case scenario where the demand is the worst-one from a deterministic scenario where the demand has a neutral behavior. The resulting strategies are called min-max…

A method for detecting malfunctions in PV solar panels based on electricity production monitoring

2017

In this paper a new method is developed for automatically detecting outliers or faults in the solar energy production of identical sets (sister arrays) of photovoltaic (PV) solar panels. The method involves a two-stage unsupervised approach. In the first stage, "in control" energy production data are created by using outlier detection methods and functional principal component analysis in order to remove global and local outliers from the data set. In the second stage, control charts for the "in control" data are constructed using both a parametric method and three non-parametric methods. The control charts can be used to detect outliers or faults in the production data in real-time or at t…

Urban smart mobility in the scientific literature — bibliometric analysis

2018

Abstract This article aims at identification of the main trends in scientific literature characterising urban smart mobility, on the basis of bibliometric analysis of articles published in the ISI Web of Science and Scopus databases. The study period was set from 2000 to 2017. Authors used a basic technique of the bibliometric analysis of the scientific literature characterising urban smart mobility with the support of the VOSviewer software. The analysis included the number of publications, citation analysis, research area analysis and the most frequent keywords. The analysis led to taking notice of current research trends dealing with the urban smart mobility. The core of the paper is a t…
