A matching-based heuristic algorithm for school bus routing problems
Ali Shafahi, Zhongxiang Wang, Ali Haghani
School bus planning problem (SBPP) has drawn much research attention due to the huge costs of school transportation. In the literature, the SBPP is usually decomposed into the rout…
School bus routing by maximizing trip compatibility
Ali Shafahi, Zhongxiang Wang, Ali Haghani
School bus planning is usually divided into routing and scheduling due to the complexity of solving them concurrently. However, the separation between these two steps may lead to w…
SCDA: School Compatibility Decomposition Algorithm for Solving the Multi-School Bus Routing and Scheduling Problem
Zhongxiang Wang, Ali Shafahi, Ali Haghani
Safely serving the school transportation demand with the minimum number of buses is one of the highest financial goals of school transportation directors. To achieve that objective…
Understanding and Visualizing the District of Columbia Capital Bikeshare System Using Data Analysis for Balancing Purposes
Kiana Roshan Zamir, Ali Shafahi, Ali Haghani
Bike sharing systems' popularity has consistently been rising during the past years. Managing and maintaining these emerging systems are indispensable parts of these systems. Visua…
Balanced scheduling of school bus trips using a perfect matching heuristic
Ali Shafahi, Sanaz Aliari, Ali Haghani
In the school bus scheduling problem, the main contributing factor to the cost is the number of buses needed for the operations. However, in the case of subcontracting the transpor…
Stochastic Emergency Response Units (ERUs) Allocation Considering Secondary Incident Occurrences
Hyoshin Park, Ali Shafahi, Ali Haghani
Location of depots and routing of emergency response units are assumed to be interdependent in the incident management system. System costs will be excessive if delay regarding rou…
