26-02-2007 - Vietnam can save water using the Neighbour Search
In collaboration with scientists from the Danish Hydraulic Institute (DHI), Gianluca Dorini uses the Neighbour Search (NS) methodology to identify optimal operation policies for the Hoa Binh, the largest reservoir in Vietnam.

Hoa Binh, which is the largest reservoir in Vietnam with a total storage capacity of 9.5 billion m3 and a live storage of 5.6 billion m3, has been operated in the Red river basin since 1990, its two main purposes being flood control and hydropower generation. In order to provide the DHI with optimal operation policies for planning purposes, the Hoa Binh problem was modelled as a Multi-Objective Stochastic Dynamic Program (MOSDP) and then solved using the Neighbour Search (NS). Please read on for the full case study.

The NS, which was developed by Gianluca Dorini in 2006 , is a revolutionary approach to the optimisation of MOSDP that enables the efficient identification of the full set of optimal trade-off solutions.

The NS methodology can be successfully applied to problems that are inherently stochastic, multi-objective and multi-stage including finance and dynamic options, telecommunications and asset management.

02-04-2007 - Service Science
Prof. Irene Ng, hosts at the Centre for Service Research the seminar: “Service Science: an Emerging Academic Discipline”.

Prof. Irene Ng (Diapason consultant) director of the Centre for Service Research (School of Business & Economics, University of Exeter) hosts the seminar entitled “Service Science: an Emerging Academic Discipline”.

The service sector comprises the vast majority of the economies of the developed nations and is expected to provide the source of growth in the near future as the manufacturing sector continues to decline. Fuelling this growth is new service development, driven by technology, customer demand and the need to develop more structured approaches to providing services that are both more effective and efficient.

Service Science, drawing from several traditional academic disciplines including operations management, marketing, human resource management, information technology, and design innovation, is an emerging discipline that provides a structured approach to identifying, analyzing and solving business-related issues within the service sector.

27/29-08-2006 - Design of sensor networks for water infrastructure

Dr. Zoran Kapelan presents a new sensor networks design methodology for an international competition on the security of water distribution systems at the Water Distribution Systems Analysis Symposium, Cincinnati, Ohio, USA.

Security of critical infrastructures and in particular security of water distribution systems against voluntary contamination and terrorist attacks has been gaining increasing world-wide attention after the 9-11 events.

In the effort of fostering the development of advanced technologies to face these emerging threats, the best research centres and new-tech companies were invited to participate in the “Battle of the Water Sensor Networks (BWSN):A Design Challenge for Engineers and Algorithms”, an international competition dealing with the design of sensor networks for the early detection of contaminants on water distribution systems.

The methodology devised by Gianluca Dorini (Diapason, Director R&D) in collaboration with other research scientist[1], along with those developed by Gary B. Trachtman (PE Associate, McGuire/Malcolm Pirnie, Inc. Birmingham, Alabama,USA) and Berry et al. (Sandia National Laboratories, USA) outperformed the results obtained by the other competitors.
