The present paper is an attempt to develop a new heuristic algorithm, find the optimal sequence to minimize the utilization time of the machines and hence their rental cost for two stage specially structured flow shop scheduling under specified rental policy in which processing times and set up time are associated with their respective probabilities including transportation time. Further jo...

The paper introduces a simple framework for analyzing the environmental effects of local transportation policies, and it reviews some evidence. In several cases, subsidies for local public transportation have led to substantial reductions in road transportation and have thereby reduced externalities. Some but not all estimates suggest positive overall welfare effects of such policies. In the ra...

W consider a two-echelon inventory system with a capacitated centralized production facility and several distribution centers (DCs). Both production and transportation times are stochastic with general distributions. Demand arrives at each DC according to an independent Poisson process and is backlogged if the DC is out of stock. We allow different holding and backlog costs at the different DCs...

The interface between transportation investment and economic development has broad ramifications that go beyond transportation’s basic purpose of moving goods and people from one place to another. Whereas there is no doubt that transportation is essential in the operation of a market economy, much still needs to be understood about ways in which an efficient transportation system can improve th...

Around the world, particularly in North America and Australia, urban sprawl combined with low density suburban development has caused serious accessibility and mobility problems, especially for those who do not own a motor vehicle or have access to public transportation services. Sustainable urban and transportation development is seen crucial in solving transportation disadvantage problems in ...

Title of Document: TRAFFIC ANALYSIS ON CUMULATIVE LAND DEVELOPMENT AND TRANSPORTATION RELATED POLICY SCENARIOS Zheng Zhu, Master of Science, 2014 Directed By: Professor Lei Zhang, Department of Civil and Environmental Engineering Numerous methods have been developed to evaluate the impact of land developments and transportation policies on transportation infrastructures. But traditional approac...

Transportation decisions have health consequences that are often not incorporated into policy-making processes. Health Impact Assessment (HIA) is a process that can be used to evaluate health effects of transportation policy. We present a rapid HIA, conducted over eight weeks, evaluating health and economic effects of proposed fare increases and service cuts to Boston, Massachusetts' public tra...
