Biography

Currently, I am a Ph.D. candidate at the Concordia Institute for Information Systems Engineering under the supervision of Prof. Fereshteh Mafakheri & Prof. Chun Wang, working on the "Sustainable Last-mile Delivery Systems" at Gina Cody school of engineering and computer science, Concordia University, Montreal, Canada. Before that, I had finished my second M.Sc., first M.Sc., and B.Sc. in Industrial Engineering at Sabanci University (Istanbul, Turkey), Sharif University of Technology (1st university in Iran based on QS), and Iran University of Science and Technology (Tehran, Iran), respectively. I am interested in developing Exact and Heuristic/Metaheuristic methods for solving "Hard" combinatorial optimization problems that arise in application areas of Operations Research, such as Last-mile Delivery, Logistics, Vehicle Routing, and Performance Evaluation. My primary skills are coding various problems and metaheuristics in C++ and Python language programming (Please check the Optimization codes section) and finding efficient solvers for optimization problems. Also, I use the Python-Gurobi interface to solve mathematical modeling problems.

Optimization codes

By Nima Moradi

Here, the optimization codes for the combinatorial problems, including Electric-Vehicle Routing Problem (EVRP) variants, Two-Echelon EVRP variants, Knapsack 0-1 (KP01), Construction Site Layout Planning (CSLP), Facility Layout Problem, Quadratic Assignment Problem (QAP), Traveling Salesman Problem (TSP), Autonomous Delivery VRP, Prize-Collecting EVRP, and Robot-aided EVRP, are provided, which have been written in C++ and Python language programming. These codes can be used free of charge for academic purposes or comparative studies. Our solution approach to these problems is mainly metaheuristic/matheuristic algorithms and an exact solver, i.e., Gurobi.

Codes for Knapsack Problem 0-1 (KP01): These algorithms are described in "Moradi, Nima, Vahid Kayvanfar, and Majid Rafiee. An efficient population-based simulated annealing algorithm for 0–1 knapsack problem. Engineering with Computers 38, no. 3 (2022): 2771-2790."
- 1st single-solution-based Simulated Annealing for the 0-1 Knapsack Problem (SAKP01_1): It uses RISP for initial solution generation and Sonuc_RI for local search.
- 2nd single-solution-based Simulated Annealing for the 0-1 Knapsack Problem (SAKP01_2): It uses RISP for initial solution generation and Zhan_RI for local search.
- 3rd single-solution-based Simulated Annealing for the 0-1 Knapsack Problem (SAKP01_3): It uses GISP for its initial solution generation and GS for its local search.
- Population-based Simulated Annealing for the 0-1 Knapsack Problem (PSAKP01): It uses RISP & GISP for initial solution generation and a mutation- and crossover-based Zhan_RI for local search.
Codes for Stochastic Facility Layout Planning Problem (STFLP):
- Simulated Annealing for GSUA-STFLP (SA-GSUA-STFLP): This algorithm solves the FLP with stochastic parameters, unequal area facilities, and grid system modeling by SA, which is described in "Moradi, N. (2019). Stochastic Facility Layout Planning Problem: A Metaheuristic and Case Study. Iranian Journal of Optimization, 11(2), 229-241."
Codes for Construction Site Layout Planning (CSLP):
- Simulated Annealing for CSLP (SACSLP): This source code implements a Simulated Annealing (SA) optimization algorithm for UA-CSLP. In this code, the example from H. Li & Love (1998), which can be easily developed, is solved. Also, this code can be used to compare the proposed algorithm with other solution techniques. This algorithm is provided in "Moradi, N., & Shadrokh, S. (2019). A simulated annealing optimization algorithm for equal and un-equal area construction site layout problems. International Journal of Research in Industrial Engineering, 8(2), 89-104."
Codes for Quadratic Assignment Problem (QAP):
- Simulated Annealing for QAP (SAQAP): The SAQAP algorithm solves the QAP using a simple SA variant (a non-greedy local search). The next versions of SA-based algorithms for QAP will be improved by using population-based and Reinforcement learning (RL)-based approaches.
Codes for Traveling Salesman Problem (TSP):
- Simulated Annealing for TSP (SATSP): The SATSP algorithm solves the TSP using a simple SA variant (a non-greedy local search). The next versions of SA-based algorithms for TSP will be improved using population-based and Reinforcement learning (RL) based approaches.
Codes for Autonomous Delivery Vehicle Routing Problem (ADVRP):
- Hybrid VNS-SA for ADVRP (case study):
- This algorithm's details and instance-generation process are described in "Moradi, Nima, Ihsan Sadati, and Bülent Çatay. Last mile delivery routing problem using autonomous electric vehicles. Computers & Industrial Engineering 184 (2023): 109552."
