A Comparative Evaluation of Selected Heuristic Solutions of Vehicle Routing Problems in Supply Chain Management
Keywords:
combinatorial optimization, Impractical problem, Heuristics, Asymptotic time complexity and Halsted complexity measure.Abstract
This work involves evaluation of three heuristics which are often used to solve
the VRP namely; nearest insertion, nearest neighbour, and tour improvement heuristics
using computer execution time, implementation complexity and asymptotic time
complexity. The research findings of this work have established that the nearest neighbour
heuristic is the most efficient in terms of execution time, program volume and
programming effort. The nearest insertion heuristics ranks next while the tour improvement
heuristic is the least efficient. Solution to a thirty-seven-node vehicle routing problem
implemented using the Nigerian State capitals and Abuja was also obtained.
