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…
Towards the Design of Respond Action in Disaster Management Using Knowledge Modeling
2017
This position paper highlights current problems linked to the aspects of the multi-agency collaboration during disaster response. The coordination and cooperation depend on the information sharing and use which must face up to interoperability, access rights, and quality problems. The research project aims at providing an assessment of information impact on the disaster response in order to support the decision-making about what information shared or what quality of data used to improve the response efficiency. Our research approach propose to combine an information system able to integrate heterogeneous data and a simulation system to assess different strategies of information sharing, dis…
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.
On the Nature of Information Management in Complex and Natural Disasters
2015
Abstract The purpose of this paper is to present reflections on the nature of information management (IM) and its role and function to support coordination in one of the largest humanitarian crises of our time, the Syria crisis. Starting from general principles for humanitarian information management, we analyze the challenges that information managers face in conflict situations, when information is – more than anywhere else – a source of power and influence. This work outlines the interdependence of advocacy and operational information management, the sensitivity of information, and barriers to information sharing. The results are complex and highly interlaced information and coordination…
Contributions from ADBIS 2018 workshops
2018
The ADBIS conferences provide an international forum for the presentation of research on database theory, development of advanced DBMS technologies, and their applications. The 22nd edition of ADBIS, held on September 2–5, 2018, in Budapest, Hungary, includes six thematic workshops collecting contributions from various domains representing new trends in the broad research areas of databases and information systems.
A model of Cyber Threat Information Sharing with the Novel Network Topology
2021
The digitized environments are particularly vulnerable to various attacks. In such a situation of a security attack, detecting and responding to attacks require effective actions. One of the most significant ways to improve resilience to security attacks is to obtain accurate and timely situational aspect of the security awareness. The efficient production and utilization of situation information is achieved by sharing information with other actors in the information sharing network quickly and reliably without compromising the confidential information of one's own organization. At the same time, it should also be possible to avoid a flood of irrelevant information in the sharing network, w…
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…
Economia della condivisione e antropologia dello scambio
2017
The article analyses the distinctive economic models based on sharing that proliferated with the rise of web 2.0 (or social web). In particular, it analyzes what sharing means in different contexts (material and immaterial goods, and services) and it questions whether sharing can be seen as a discrete category, different from both market exchange and gift. Finally, the article questions the role of law with respect of these new economic activities.
Inventory policies and information sharing in multi-echelon supply chains
2011
The aim of this article is to show how to modify a replenishment rule in relation to the operational information shared by suppliers. More specifically, we present a model of an Automatic Pipeline Variable Inventory and Order-Based Production Control System rule for a multi-echelon supply chain characterised by different increasing levels of shared information. A numerical study is presented to underline the performance differences for three variants of the smoothing order rule in terms of bullwhip reduction, inventory stability and operational and customer responsiveness. Results show how the effectiveness of a smoothing replenishment rule depends on the level of information sharing.
