Abstract:

Presently, the takeaway industry continues to demonstrate robust growth, with takeaway services becoming increasingly entrenched in people's daily lives. Nevertheless, given the differences in focal points of platforms, consumers, and riders, a pronounced discord of interests has emerged among the three parties, even hindering the development of the industry. Distribution timeliness, a pivotal factor, impacts not only customer satisfaction and platform profits but also directly influences the rewards and punishments for riders. To address these challenges, a multi-objective routing optimization problem is proposed for takeout delivery, considering the rewards and punishments for riders based on the perspective of distribution timeliness. The primary aim of this study is to further balance the interests of all parties dynamically. A soft time window concept is adopted to portray customer expectations and tolerance of delivery time, and a linear time satisfaction function is constructed to assess customer satisfaction. Concurrently, the rider's rewards and penalties are designated, encompassing the rider's overtime penalty cost based on on-time rate, the order overtime penalty cost in step-pricing style, and the performance reward based on satisfaction. The functions of rider revenue, driving cost, waiting cost, and platform revenue are then combined to establish a complex objective optimization model for maximizing customer satisfaction, rider revenue, and platform profit. Secondly, an enhanced NSGA-II algorithm based on KNN classification is proposed. The proposed algorithm first allocates orders based on geographic distance and time window, generates high-quality and diverse initial populations, and subsequently outputs a Pareto solution using the enhanced NSGA-II algorithm. To assess the efficacy of the proposed algorithm, two ordinary region examples and one commercial region example are utilized for testing purposes. It then compares this algorithm with the traditional NSGA-II and MOPSO algorithms for validation purposes. The convergence of the algorithm and the diversity of the solution set are further verified by analyzing the iterative convergence curves of each objective function as well as the indicators of spacing and maximum spread of the solution set. Finally, a comparative analysis of customer satisfaction, rider revenue, and platform profit under different reward and punishment rules is conducted. It is indicated that the platform's punishment measures can enhance delivery efficiency, foster customer satisfaction and augment platform revenue. Equitable sanctions have the potential to engender a mutually beneficial scenario for all three parties. While the incentive mechanism may temporarily reduce platform revenue, it can enhance delivery efficiency and rider revenue. Consequently, a theoretical foundation is offered for the coordination of interests among multiple parties in the future of takeaway services and the establishment of a platform's reward and punishment mechanism for riders.

Key words: takeout delivery, distribution timeliness, rewards and penalties of riders, multi-objective optimization, the improved NSGA-II algorithm
