Universal Design of Information Sharing Tools for Disaster Risk Reduction

2019

International audience; Disaster information sharing tools are an important aspect of disaster resilience, and it is of utmost importance that these tools are accessible and usable for as many potential users as possible. In this paper, we evaluate the accessibility of a selection of tools for crowdsourcing disaster situation information. As our evaluation shows that the selected tools are not fully accessible, we provide recommendations for mitigation, as well as highlight the importance of further research in this area.

On the Bullwhip Avoidance Phase: The Synchronised Supply Chain

2012

Abstract The aim of this paper is to analyse the operational response of a Synchronised Supply Chain (SSC). To do so, first a new mathematical model of a SSC is presented. An exhaustive Latin Square design of experiments is adopted in order to perform a boundary variation analysis of the main three parameters of the periodic review smoothing ( S ,  R ) order-up-to policy: i.e., lead time, demand smoothing forecasting factor, and proportional controller of the replenishment rule. The model is then evaluated under a variety of performance measures based on internal process benefits and customer benefits. The main results of the analysis are: (I) SSC responds to violent changes in demand by re…

Understanding the Health Disaster: Research Design for the Response to the 2014 West African Ebola Outbreak

2015

International audience; The 2014 Ebola outbreak in West Africa is the largest ever in history, affecting multiple countries and to this date, the World Health Organization has registered more than 6,500 deaths attributed to Ebola. The challenges arising from this outbreak to responders worldwide do not follow the standard characterisation or response patterns of natural sudden onset vs. conflict disasters. Rather, it is a medical emergency, which is intertwined with multiple challenges in the sectors decision-making, coordination, logistics and information management. In this paper, we present our research framework, which is based on desk research and initial interviews with responders. Th…

Insights on Partial Information Sharing in Supply Chain dynamics

2015

This paper provides an assessment of partial Information Sharing (IS) in Supply Chain (SC). We study the dynamics of collaborative multi-echelon structure, characterized by an increasing level of information visibility among partners. To do so, we mathematically model six four-echelon serial SCs via difference equations and conduct numerical simulations on the basis of a robust design of experiment. Results shows how (1) as the extent of IS increases, the performance of whole SC improves as well, and (2) the impact of IS depends not on which particular members are involved but on the number of collaborative members.

Partial/Asymmetrical Information sharing in Supply Chain: A bibliometric analysis

2016

The importance of Information Sharing (IS) between an enterprise and its customers or cooperating companies has been long recognized in Supply Chain (SC) research literature. In this paper we perform an exploratory analysis of the current state-of-art and challenges in the field of partial/asymmetrical IS in SC. To fulfil our objective we carry out a bibliometric analysis by adopting BibExcel and Gephi tools. We identify 115 articles and generate several co-citation maps. Our results show that the concepts of partial and asymmetrical IS in SCs are not well defined in literature.

The effect of inventory record inaccuracy in information exchange supply chains

2015

Abstract The goal of this paper is to quantify the impact of Inventory Record Inaccuracy on the dynamics of collaborative supply chains, both in terms of operational performance (i.e. order and inventory stability), and customer service level. To do so, we model an Information Exchange Supply Chain under shrinkage errors in the inventory item recording activity of their nodes, present the mathematical formulation of such supply chain model, and conduct a numerical simulation assuming different levels of errors. Results clearly show that Inventory Record Inaccuracy strongly compromises supply chain stability, particularly when moving upwards in the supply chain. Important managerial insights…

Information providers e information sharing mechanisms nel mercato creditizio italiano.

2015

Il presente lavoro esamina i principali casi aziendali di information providers e sistemi di information sharing operanti nel mercato creditizio italiano, con una prospettiva di analisi prettamente economico-aziendale. Sono analizzati i modelli di business dei primi 5 operatori italiani: Cerved, Crif, Infocamere, Experian, Euler Hermes Siac. Sarà, inoltre, preso in esame il sistema di condivisione di informazioni di natura pubblica, gestito dalla Banca d’Italia, che ha un ruolo di rilievo nel sistema creditizio italiano. Quello che emerge dall’analisi è un quadro molto variegato dei sistemi di informazione creditizia operanti in Italia in quanto, accanto al tradizionale business dell’inform…

What drives the disintegration of the loan origination value chain in the banking business

2015

Purpose - The purpose of this paper is to analyze the vertical disintegration of the bank loan origination value chain. This paper conducts a study on the credit information market from the perspective of the bank's decision to vertically disintegrate the loan origination value chain. The main aim is to identify the relevant drivers of the decision to vertically disintegrate the credit assessment phase in the lending business.Design/methodology/approach - Transaction cost economics and information asymmetry are the typical perspectives of analysis of the vertical scope of business value chains.Findings - This paper argues that in order to capture the drivers underlying the dynamic evolution…

Literature Review of Scientific Articles about Cyber Information Sharing

2021

This literature review presents a review of cyber information sharing based on systematic queries in four scientific databases. Hundreds of articles were handled and clustered. Relevant publications concerning cyber information sharing are succinctly described in the paper. The findings are discussed from the perspective of how to develop a cybersecurity information sharing system and what possible features might be included in the system. The literature review will comprise a new database for the Echo Early Warning System (E-EWS) concept. E-EWS aims at delivering a security operations support tool, enabling the members of the ECHO network to coordinate and share information in near real-ti…
