“…A multi-objective optimization problem could be developed, taking into consideration the time-varying stochastic price-dependent demand (Ghoreishi et al, (2015)) and robust algorithms can be developed as solution methodologies (Kara et al, (2019), Pervin et al, (2018, Roy et al, (2017), andÖzöugür et al, (2016)). Moreover, machine learning algorithms (Alkahtani, et al, (2019) including regression methodologies ( (Taylan et al, 2019b) and (Taylan et al, 2019a)), artificial neural networks and support vector machines ( (Erdogan et al, 2019), (Savku et al, (2014) and Savku et al, (2018)), modern optimization techniques (Alp et al, (2011)) and environmentally conscious optimization (Paksoy et al, 2014) can be used for predicting the fuel pricing scenarios and bunker fuel prices at different port of calls based on the historical data. In future, this research could also be extended by using weather data to estimate the real-time fuel consumption which may differ depending upon the weather conditions in the voyage.…”
