The proposed model and algorithm are employed to solve a fruit distribution problem. However, this study improves the original GE algorithm with discretization, non-dominated sorting, and crowding distance approaches. GE algorithm is a new metaheuristic which was originally proposed for continuous problems with a single objective.
This paper solves the proposed model using a many-objective gradient evolution (MOGE) algorithm. The proposed VRP model also considers time windows, different travelling time during peak hour and off-peak hour, and working hours. In order to address this problem, this study proposes a green vehicle routing problem (VRP) for perishable products which optimizes the operational cost, deterioration cost, carbon emissions and customer satisfaction. In addition, high frequency of transportation may also contribute to air pollution. In addition to the time limitation on transport, high frequency of transportation may lead to high transportation cost, making the optimization of transportation cost for delivering perishable products very important in this industry. Some perishable products such as foods and medicine require a special treatment during delivery due to their limited lifetime, and all perishable products must be transported as quickly as possible before they spoil.

Since the trend of consolidation is and has historically been upward, fewer and fewer individuals or organizations control increasing shares of the mass media in our country. Media ownership in Australia is one of the most concentrated in the world ( Learn more).

Ukraine’s President Volodymyr Zelenskiy shared a video clip showing the aftermath of the strike, showing wrecked cars, buildings with shattered windows and fires burning in the street. Details soon” Kyiv Mayor Vitali Klitschko wrote on Telegram on Monday. “Several explosions in the Shevchenkivskyi district, in the city centre. There is information about strikes in many cities of our country,” Kyrylo Tymoshenko, deputy head of the president’s office, said on social media, calling on the population to “stay in shelters”. Several explosions rocked multiple cities around Ukraine, including capital Kyiv at morning rush hour after Russian president Vladimir Putin blamed Ukraine for the Russia-Crimea bridge blast.
