EUROPEAN CONFERENCE ON QUEUEING THEORY 2016

International audienceThis booklet contains the proceedings of the second European Conference in Queueing Theory (ECQT) that was held from the 18th to the 20th of July 2016 at the engineering school ENSEEIHT, Toulouse, France. ECQT is a biannual event where scientists and technicians in queueing theory and related areas get together to promote research, encourage interaction and exchange ideas. The spirit of the conference is to be a queueing event organized from within Europe, but open to participants from all over the world. The technical program of the 2016 edition consisted of 112 presentations organized in 29 sessions covering all trends in queueing theory, including the development of the theory, methodology advances, computational aspects and applications. Another exciting feature of ECQT2016 was the institution of the Takács Award for outstanding PhD thesis on "Queueing Theory and its Applications"

Property Crime and Law Enforcement in Italy. A Regional Panel Analysis 1980-95

In this paper a Cobb-Douglas utility function is introduced and solved for a dynamic equation of property crime supply and its determinants, namely deterrents and income. Thereafter, all variables are empirically tested, by means of a simultaneous equations model, for the sign and magnitude of their mutual relationships in a panel of Italy and its two economically and culturally different areas, the North and the South. The period scrutinized is 1980-95 and the results obtained widely differ among the two. When appropriately modeled and instrumented, in fact, property crime is found to react to police and criminal justice deterrence, and also to incomes, with different parameter magnitudes and significance. The same diversity applies to the parameters related to deterrence, flawed in quite a few cases by scarce law enforcement and productivity, and to those related to local incomes, which still reflect for the South a tendency of crime to substitute for legal activities.Models with Panel Data, Illegal Behavior and the Enforcement of Law

Reflections on queue modelling from the last 50 years

Queueing theory continues to be one of the most researched areas of operational research, and has generated numerous review papers over the years. The phrase 'queue modelling' is used in the title to indicate a more practical emphasis. This paper uses work taken predominantly from the last 50 years of pages of the Operational Research Quarterly and the Journal of the Operational Research Society to offer a commentary on attempts of operational researchers to tackle real queueing problems, and on research foci past and future. A new discipline of 'queue modelling' is proposed, drawing upon the combined strengths of analytic and simulation approaches with the responsibility to derive meaningful insights for managers
