On the operational level, production scheduling and transportation planning are usually carried out by different stakeholders, making locally bounded decisions. The integration of both tasks allows for a better management of disruptions that affect the effectiveness of the production and transportation systems. In this paper we study the integrated production and transportation scheduling probl...

This study introduces space, transportation, and money into an economic growth model. Growth theory neglects the importance of transportation on economic growth and transportation economics fails to properly explain how changes in transportation conditions (such as technological improvement, infrastructure investment, and oil prices) affect long-term economic growth. By proposing a growth model...

Allocating and routing problems in the field of transportation engineering are generally solved using the objective function of minimizing transport cost. Transport risk is a main concern in hazardous material transportation, mainly dependent on the vision of decision makers (national and/or local authorities). In this research work, a trade-off approach has been proposed to determine the safes...

Pipeline as a safe and economic way, play an important role in the oil transportation. In this system, various type of products are injected into the pipeline sequentially without any physical separation, and on the other side, at the distribution centers, the products are received and depot in the corresponding tanks. Scheduling of oil transportation operations in a given time horizon is an ma...

Chinese cities are experiencing major environmental e!ects from fossil fuel-based energy consumption for mainly residential and, increasingly, urban transportation uses. Community energy management (CEM) is a sustainable energy strategy which looks at how purposely shaping the built environment and designing urban services in consideration of energy production, distribution and use could a!ect ...

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 integrated planning of transportation of raw material, production and distribution of products of the supply chain for a large pulp company is studied. The planning period is one year and a numbers of time periods are considered. The tactical decisions included in the model regard transportation of raw materials from harvest areas to pulp mills, production mix and contents at pulp mills, di...

Hydrogen infrastructure costs will vary by region as geographic characteristics and feedstocks differ. This paper proposes a method for optimizing regional hydrogen infrastructure deployment by combining detailed spatial data in a geographic information system (GIS) with a technoeconomic model of hydrogen infrastructure components. The method is applied to a case study in Ohio in which coal-bas...
