A probabilistic (max, +) approach for determining railway infrastructure capacity
We consider the problem of determining the capacity of a planned railway infrastructure layout under uncertainties In order to address the long term nature of the problem in which the exact future demand of service is un known we develop a timetable free approach to avoid the speci cation of a particular timetable We consider a generic infra element that allows a con cise representation of many...
متن کاملRailway infrastructure saturation using Constraint Programming approach
Railway infrastructure managers now have to deal with the new operators' requests for capacity. Planning the new construction or reconstruction of infrastructures must be carried out very carefully due to the huge investment needed. This paper studies a Constraint Programming (CP) model of the 'Railway Infrastructure Saturation Problem" (RISP). The model applies to assess the capacity of a junc...
متن کاملA New Approach to Nonstandard Analysis
In this paper, we propose a new approach to nonstandard analysis without using the ultrafilters. This method is very simple in practice. Moreover, we construct explicitly the total order relation in the new field of the infinitesimal numbers. To illustrate the importance of this work, we suggest comparing a few applications of this approach with the former methods.

هدف اصلی از این تحقیق به دست آوردن و مقایسه حق بیمه باورمندی در مدل های شمارشی گزارش نشده برای داده های طولی می باشد. در این تحقیق حق بیمه های پبش گویی بر اساس توابع ضرر مربع خطا و نمایی محاسبه شده و با هم مقایسه می شود. تمایل به گرفتن پاداش و جایزه یکی از دلایل مهم برای گزارش ندادن تصادفات می باشد و افراد برای استفاده از تخفیف اغلب از گزارش تصادفات با هزینه پائین خودداری می کنند، در این تحقیق ...
15 صفحه اولImpact of the Operation and Infrastructure Parameters to the Railway Track Capacity
Abstract—The railway transport is considered as a one of the most environmentally friendly mode of transport. With future prediction of increasing of freight transport there are lines facing problems with demanded capacity. Increase of the track capacity could be achieved by infrastructure constructive adjustments. The contribution shows how the travel time can be minimized and the track capaci...
