a mathematical model for finding the optimal locations of railway stations
Authors
abstract
regarding the importance of competitive advantages among the transportation systems, improving the costumer’s satisfaction is an important factor in attracting them to these systems. in this research, we focus on the effects of constructing new stations on users and a new mathematical model is proposed for this problem. in the proposed model, two simultaneous effects on customers by constructing new stations are investigated. one effect is the improvement of the demand access to the railway network and the other one is related to the increase in the travelling time for customers sitting in the train. as the first effect, the less the customer’s distance to the stations, the more attractive to use this system and the second effect concerns the increased in the traveling time in new stops which may result to customer’s dissatisfaction. the proposed mathematical model achieves the time optimality, furthermore; it maximizes the covered population to locate the stations. for locating the optimal site for new stations, we need to apply the population usage information. the proposed model is examined on the mashhad’s subway as a case study and the results are reported.

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...

abstract nowadays, the science of decision making has been paid to more attention due to the complexity of the problems of suppliers selection. as known, one of the efficient tools in economic and human resources development is the extension of communication networks in developing countries. so, the proper selection of suppliers of tc equipments is of concern very much. in this study, a ...
15 صفحه اولA mathematical model for hazmat and freight transportation in railway networks
In this paper, we develop a freight transportation model for railway network considering hazmat transportation issue. In the transportation system considered, different customers can request for carrying hazmat and non- hazmat boxes. It is assumed that the sequence of the trains in the network is known. The objective is assigning the non-hazmat boxes and hazmat boxes to wagons of the trains so ...

آب حاصل از بارش منبع تأمین نیازهای بی شمار جانداران به ویژه انسان است و هرگونه کاهش در کم و کیف آن مستقیماً حیات موجودات زنده را تحت تأثیر منفی قرار می دهد. نوسان سال به سال بارش از ویژگی های اساسی و بسیار مهم بارش های سالانه ایران محسوب می شود که آثار زیان بار آن در تمام عرصه های اقتصادی، اجتماعی و حتی سیاسی- امنیتی به نحوی منعکس می شود. چون میزان آب ناشی از بارش یکی از مولفه های اصلی برنامه ...
