considered supply chain in this article consists of one vendor and multiple retailers where the vendor applies vendor managed inventory. considering vendor as a leader and retailers as followers, stackelberg game theory is applied for modeling and analyzing this system. a general mixed integer nonlinear model is developed which can optimizes the performance of the system under revenue sharing c...

In recent decades, urban planning has tended to humanist urbanism. In this regard foot travels and bicycle use are the two strategies that urban planners and transportation engineers are using them as adequate alternatives for making cities more people friendly. Using bicycle is known as a strategy that has a great role in decreasing traffic among developing countries in recent decades. These c...

This paper presents a kriging method for spatial prediction of temporal intensity functions, situations where point process is observed at different locations. Assuming that several replications the are available sites, this avoids assumptions like isotropy, which not valid in many applications. As part derivations, new nonparametric estimators mean and covariance functions processes introduced...

Urbanization and motorization increases encourage traffic congestion related problems. This triggers alternative innovative solution in the context of advanced technology. The necessity providing balanced modal distribution intermodal integration is a well-known issue. In this paper within framework firstly existing case expressed on axial developing developed countries then electrical bicycle ...

OBJECTIVE The purpose of this study was to describe bicycle helmet use among Montreal cyclists as a step towards injury prevention programming. METHODS Using a cross-sectional study design, cyclists were observed during 60-minute periods at 22 locations on the island of Montreal. There were 1-3 observation periods per location. Observations took place between August 16 and October 31, 2011. S...

PROBLEM AND METHOD This paper takes a critical look at the present state of bicycle infrastructure treatment safety research, highlighting data needs. Safety literature relating to 22 bicycle treatments is examined, including findings, study methodologies, and data sources used in the studies. Some preliminary conclusions related to research efficacy are drawn from the available data and findin...
