摘要

本文研究了一个真实的随机感染性医疗废物(IHW)收集问题。废物从斯法克斯省(突尼斯)的所有医院收集到焚化炉。减少医疗传染性废物对突尼斯在保健机构中的承诺构成挑战。该问题被认为是一个随机需求的有能力车辆路径问题。提出了两种组合方法:(1)精确方法与蒙特卡罗模拟相结合;(2)相同的模拟工具与Clarke and Wright (C&W)节省相结合。这些建议的方法提供了一套解决方案，帮助Sfax市的决策者执行适当的IHW运输路线系统。该方法的结果给出了一个通用的解决方案，该解决方案使用精确的方法出现频率高，尽管需求的随机特性。(C&W)启发式在合理的时间内提供了良好的结果。

Solving a routing problem of collect infectious healthcare waste with stochastic demand: case of Sfax Governorate in Tunisia

This paper deals with a real stochastic infectious healthcare waste (IHW) collection problem. The waste was collected from all hospitals in the governorate of Sfax (Tunisia) to an incinerator. The reduction of medical infectious waste represents a challenge for Tunisia's commitments in healthcare institutions. This problem is considered as a Capacitated Vehicle Routing Problem with Stochastic Demand (CVRPSD). Two combined approaches are proposed: (1) a combination of exact method with a Monte Carlo simulation, (2) a combination of the same simulation tools with Clarke and Wright (C&W) saving. These proposed approaches provide a set of solutions which help the decision-makers of the Sfax municipality to perform an adequate IHW transportation routing system. The approaches results give one common solution that appears with a high frequency using an exact method despite the stochastic character of demands. The (C&W) heuristic provides good results in a reasonable time.

期刊介绍： There is an increasing demand for transportation solutions that are responsive, safe, sustainable, smart and cost-efficient. This has resulted in increased emphasis on responsive intermodal transportation systems. WRITR provides an international forum for the critical evaluation and dissemination of research and development in all areas related to intermodal transportation. Research disseminated via WRITR has significant impact on both theory and practice, and is of value to academics, practitioners and policy makers in this field. Topics covered include: -International trade and transportation -Infrastructure, network design and optimisation -Design, planning and control of transportation systems -Intermodal, intelligent and sustainable transportation solutions -Transportation modes (air, rail, road, sea, pipe) -Transportation cost/benefit analysis -Railroad, terminal and port development -Port/terminal operations and management -Warehousing and inventory management -Transportation regulations, standards and security -Environmental impact, liability and insurance -Risk analysis and management -Information technology and decision support systems -Strategic alliances and relationship management -Government involvement and incentives
