Question

Logistics modeling is a powerful analytical technique for effective planning of waste storage,treatment, and disposal activities. Logistics modeling facilitates analyses of alternate scenarios for future waste flows, facility schedules, and processing or handling capacities. These analyses provide an increased understanding of the specific needs for waste storage, treatment, and disposal while adequate time remains to plan accordingly. They also help to determine the sensitivity of these needs to various system parameters. This paper discusses a logistics modeling system developed by the Pacific Northwest Laboratory (PNL) to aid in solid waste planning for a large industrial complex managing many different types and classifications of waste. The basic needs for such a system are outlined, and the approach adopted in developing the system is described. A key component of this approach is the development of a conceptual model that provides a flexible framework for modeling the waste management system and addressing the range of logistics and economic issues involved. Developing an adequate description of the waste management system being analyzed is discussed. Examples are then provided of the types of analyses that have been conducted. The potential application of this modeling system to different settings is also examined.

物流建模是一个有力的分析技术,有效地规划废弃物贮存,处理和处置活动. 物流建模便于分析候补设想未来废弃物流向,设施时刻表,加工或处理能力. 这些分析提供一个增进了解的具体需要废物贮存,处理, 和处置,同时有足够的时间仍然作出相应的计划. 他们还帮助确定的敏感性,这需要各个系统参数. 本文论述了物流系统建模系统是由美国西北太平洋实验室( PNL组) ,以援助在固体废物规划 一个大型工业园区管理很多不同的类型和分类的废物. 基本需要建立这样一个系统,并着重阐述了所采用的方法,在开发系统原理. 一个关键组成部分,这一做法是建立一个概念模型提供了一个灵活的架构建模 废物管理制度和处理各种后勤和涉及的经济问题. 发展中国家的充分描述的废物管理系统进行分析讨论. 实例,然后规定哪些类型的分析,已经进行. 极具应用潜力的这个模拟系统,以不同的设置也进行了审查.
