Solid waste collection (SWC) has been one of the growing challenges throughout the world due to the development of urbanization and uncontrolled growth of the population. It is a complex process that is expensive and requires the elaborate logistics management and in-depth mathematical computation. Hence, there is an urgent necessity to develop an efficient waste collection process while saving time, fuel, labour, maintenance costs, and carbon emissions. This goal of this is paper is to deliver a comprehensive review of the SWC system concerning solid waste collection objectives, constraints, the different optimization approaches, and models, along with their strengths and weakness. The different types of optimization objectives and constraints on SWC are highlighted towards improving solid waste collection and minimizing the cost. Furthermore, this review has classified the available optimization methods into different categories and technologies to provide a clear understanding for the readers. Besides, future research gaps are identified through the investigation of various key issues and challenges of the existing methods. Moreover, the significant contributions of SWC in connection to sustainable development goals (SDGs) are explained thoroughly. Finally, the review delivers some important proposals that would be beneficial to the researchers and policymakers to design an efficient and robust SWC system toward achieving SDGs.

固体废物收集的优化目标,约束条件,建模方法及其对实现可持续发展目标的挑战

由于城市化的发展和人口的无节制增长,固体废物收集(SWC)已成为世界范围内日益严峻的挑战之一。这是一个昂贵的复杂过程,需要精心的后勤管理和深入的数学计算。因此,迫切需要开发一种有效的废物收集方法,同时节省时间,燃料,人工,维护成本和碳排放。本文的目的是就固体废物收集的目标,限制,不同的优化方法和模型以及它们的优缺点,对SWC系统进行全面的回顾。强调了SWC的不同类型的优化目标和约束,以改善固体废物收集并最小化成本。此外,本文将可用的优化方法分为不同的类别和技术,以使读者有一个清晰的了解。此外,通过对各种关键问题和现有方法的挑战进行调查,可以发现未来的研究差距。此外,对SWC在可持续发展目标(SDGs)方面的重大贡献进行了详尽的解释。最后,该评论提出了一些重要的建议,这些建议将有益于研究人员和决策者设计一个有效而强大的SWC系统,以实现SDG。通过对各种关键问题和现有方法的挑战进行调查,可以确定未来的研究差距。此外,对SWC在可持续发展目标(SDGs)方面的重大贡献进行了详尽的解释。最后,该评论提出了一些重要的建议,这些建议将有益于研究人员和决策者设计一个有效而强大的SWC系统,以实现SDG。通过对各种关键问题和现有方法的挑战进行调查,可以确定未来的研究差距。此外,对SWC在可持续发展目标(SDGs)方面的重大贡献进行了详尽的解释。最后,该评论提出了一些重要的建议,这些建议将有益于研究人员和决策者设计一个有效而强大的SWC系统,以实现SDG。
