随着城市发展水平的不断提高,人们生活节奏的不断加快,消费的多样化趋势越发明显,这些都加大了城市垃圾数量的急剧上升,对环境的影响日趋严重,给城市的消化系统带来很大的压力。如何处理城市垃圾变成了一个亟待解决的大问题,又由于城市垃圾的种种特性,例如成份复杂性、源头分散性、有回收价值性等的存在,使得城市垃圾处理过程中对物流系统的要求变得很高。因此,垃圾回收物流系统就显得十分重要了。如何建立一套合理、高效、完整的物流系统将直接影响到城市垃圾回收工作的好坏和资源再利用的效率。 相似文献

Accurate demand forecasting is one of the key aspects for successfully managing restaurants and staff canteens. In particular, properly predicting future sales of menu items allows for a precise ordering of food stock. From an environmental point of view, this ensures a low level of pre-consumer food waste, while from the managerial point of view, this is critical to the profitability of the restaurant. Hence, we are interested in predicting future values of the daily sold quantities of given menu items. The corresponding time series show multiple strong seasonalities, trend changes, data gaps, and outliers. We propose a forecasting approach that is solely based on the data retrieved from point-of-sale systems and allows for a straightforward human interpretation. Therefore, we propose two generalized additive models for predicting future sales. In an extensive evaluation, we consider two data sets consisting of multiple time series collected at a casual restaurant and a large staff canteen and covering a period of 20 months. We show that the proposed models fit the features of the considered restaurant data. Moreover, we compare the predictive performance of our method against the performance of other well-established forecasting approaches. 相似文献

从运输问题的性质来看,城市垃圾运输处理问题应属于废弃物流问题的一种,同时也是一种多目标、多层次、有特殊约束的运输问题。传统对城市垃圾的研究基本都集中在末端治理和源头控制,以研究垃圾处理模型为主。本文结合国内外有关垃圾处理的文献,对城市垃圾处理的运输路线、第三方物流运输模式、运输处理算法和模型建立以及回收运输网络系统等方面进行了论述,同时针对城市生活垃圾处理站选址优化、物流系统优化等问题提出了合理的对策和建议。 相似文献

This paper presents a routing and location (R&L) model able to help design an efficient reverse logistics channel for food waste, with particular attention to the waste generated at the retail stage of a food supply chain (FSC). The model, developed in Microsoft ExcelTM, is detailed along with its application in the Emilia-Romagna region of Italy, which is currently the location of a research project aimed at finding alternative ways to recover food waste rather than disposing of it in landfill sites. Several analyses are carried out exploiting the model, to derive some findings about the economic profitability of setting up a reverse logistics channel to recover food waste in the targeted region, and divert it to alternative use. As there are currently no studies that examine the problem of recovering food waste in Italy, this paper is expected to represent an interesting addition to the literature on this issue. 相似文献

This work presents a decision support system to facilitate efficient urban last-mile distribution. Orders are collected and delivered by a fleet of both conventional vehicles owned by a logistics provider and cargo-bikes operated by freelancers. Additionally, micro-hubs are operated to perform transshipments between multiple vehicles. To investigate the corresponding problem setting, an agent-based simulation is developed, which uses dynamic optimisation procedures to generate and select vehicle routes and transshipment points. Experiments motivated by dynamic real-world urban restaurant delivery services investigate the impact of cargo-bikes, urban consolidation and guaranteed delivery times. Potentials are discussed and implications for successful implementations are provided. Results highlight the importance of having a sufficient number of active cargo-bikes available and benefits of incorporating consolidation strategies to guarantee timely deliveries. 相似文献
