Project Title: Further Development With Existing Search and Optimisation Algorithms Student: Elliot Charles Course: MSc in Scientific Computation Abstract: For a logistics company, planning out an efficient routing schedule is a computationally complex task. Finding a solution that satisfies all customers demands’ and time windows in a fixed time frame is difficult and can be fundamental for profitability in this industry. Therefore, it is of upmost importance that quality solutions are able to be employed into a logistical system. To provide assistance on this problem, this study formulates and implements a multiobjective vehicle routing problem with time windows into two separate solvers, Gurobi and OpenSolver. Five separate objectives were studied alongside testing, benchmarking solver performance and a look into the pairwise relationship between objectives. The product of this is a high performing optimiser, capable of reliably producing high quality routing solutions to the MOVRPTW for different problem instances and results to reinforce the pairwise relationship between objectives.
