A mechanism for determining Tanker Truck transport rates: a case of oil products supply chain
Management Science, 2013Co-Authors: Mostafa Mousavi, Mohammad Bakhshayeshi Baygi, Elnaz Miandoabchi, Narin Asgari, Reza Zanjirani FarahaniAbstract:In order to min imize costs of an oil products distribution company, it is important to determine the appropriate transport rates (TRs) that lead to satisfying both the transporters and the company. This paper introduces a systematic and scientific method for calcu lating the TRs for Tanker Trucks. Calculating TRs is based on a co mb ination of finished cost and engineering economics techniques in which all the costs related to the Tanker Truck transportation are considered as financial flows over time. Finally, we explain about designing a computer-based system for calculat ing the TRs and estimating the required budget.

stabilized finite element interface capturing technique for parallel computation of unsteady flows with interfaces
Computer Methods in Applied Mechanics and Engineering, 2000Co-Authors: Shahrouz Aliabadi, Tayfun E TezduyarAbstract:We present the stabilized-finite-element/interface-capturing (SFE/IC) method developed for parallel computation of unsteady flow problems with two-fluid interfaces and free surfaces. The SFE/IC method involves stabilized formulations, an interface-sharpening technique, and the enforcement of global mass conservation for each fluid. The SFE/IC method has been efficiently implemented on the CRAY T3E parallel supercomputer. A number of 2D test problems are presented to demonstrate how the SFE/IC method works and the accuracy it attains. We also show how the SFE/IC method can be very effectively applied to 3D simulation of challenging flow problems, such as two-fluid interfaces in a centrifuge tube and operational stability of a partially filled Tanker Truck driving over a bump.

Comprehensive Risk Assessment of Health-Related Hazardous Events in the Drinking Water Supply System from Source to Tap in Gaza Strip, Palestine.
Journal of environmental and public health, 2020Co-Authors: Samer Abuzerr, Hadi, Kate Zinszer, Simin Nasseri, Masud Yunesian, Amir Hossein Mahvi, Ramin Nabizadeh, Shimels Hussien MohammedAbstract:Background The traditional approach in the management of the quality drinking water, and relying on end-product testing, has proven ineffective in protecting public health. Therefore, the transition to a systematic approach in drinking water supply systems management from the source to the consumer tap was taken as a water safety plan (WSP). Objective The study aims to investigate the health-related hazardous events in order to decide on the best risk-reduction strategies in the supply of drinking water in the Gaza strip. Methods A semiquantitative matrix method for risk assessment was applied. Also, chlorine residual, electrical conductivity, and nitrate concentration further tested in 109 water wells, 109 small-scale water desalination plants, 197 Tanker Trucks, and 384 households distributed over five governorates of the Gaza strip. Results The mean of the measured chlorine residual values was less than the recommended national and international limits (0.2-1 mg/liter). The mean of electrical conductivity at catchment points and household municipal water taps was 2165.1 μS·cm-1 and 2000 μS·cm-1, respectively. Furthermore, zero percent of water samples met the recommended criteria, indicating that the groundwater in the Gaza strip is nonpotable. Only 12.8% and 8.8% of water samples met the permissible levels at catchment areas and municipal water at household, respectively, indicating sever health impacts on the public. Moreover, the most hazardous events were related to high levels of groundwater salinity, the low level of disinfection, the effect of electricity outages on the efficiency of the desalination process, and leakage of water from the Tanker Truck tank reservoirs. Therefore, urgent interventions are required to improve the quality of water and to mitigate the possible health effects. Conclusion The prioritization of hazardous events that are proportional to the degree of their attributed risk could help guide in making the right risk-reduction decisions. Urgent interventions are required to improve the quality of water and to mitigate the possible health effects.
