In global demand of improvement of electrical and electronic waste management systems, stakeholders look for effective collection systems that generate minimal costs. In this study we propose a novel model for application in mobile collection schemes - on demand that waste be taken back from household residents. This type of the waste equipment collection is comfortable for residents as they can indicate day and time windows for the take-back. Collecting companies are interested in lowering operational costs required for service. This lowering includes selection of a sufficient number of vehicles and employees, and then minimising the routes' length in order to achieve savings in fuel consumption, and lowering of emissions. In the proposed model we use a genetic algorithm for optimisation of the route length and number of vehicles and fuzzy logic for representation of the household residents' satisfaction on the take-back service provided by collection companies. Also, modern communication channels like websites or mobile phone applications can be used to send the waste equipment take-back request from the household, so it has the potential to be developed in future applications. The operation of the model has been presented in the case study of a city in southern Poland. The results can be useful for collecting companies and software producers for preparation of new applications to be used in waste collection.
在全球对改进电气和电子废物管理系统的需求下,利益相关者正在寻找能够产生最小成本的有效收集系统。在本研究中,我们提出了一种适用于移动收集计划(即按需从居民家中回收废物)的新型模型。对于居民来说,这种废物设备收集方式非常方便,因为他们可以指定回收的日期和时间窗口。收集公司有兴趣降低服务所需的运营成本。这种降低包括选择足够数量的车辆和员工,然后最小化路线长度,以节省燃料消耗并降低排放。在提出的模型中,我们使用遗传算法来优化路线长度和车辆数量,并使用模糊逻辑来表示居民对收集公司提供的回收服务的满意度。此外,还可以使用现代通信渠道(如网站或移动电话应用程序)来发送废物设备回收请求,因此它有可能在未来的应用中得到进一步发展。该模型的运行情况在波兰南部一个城市的案例研究中进行了展示。研究结果对收集公司和软件制造商开发新的应用程序用于废物收集具有参考价值。
