We introduce a unified modeling and solution framework for various classes of rich vehicle and inventory routing problems as well as other probability-based routing problems with a time-horizon dimension. Demand is assumed to be stochastic and non-stationary, and is forecast using any forecasting model that provides expected demands over the planning horizon, with error terms from any empirical...

In this paper, we estimate conditional logit models of generator’s choice of waste management facilities (TSDFs) for shipments of halogenated solvent waste documented by the manifests filled out in California in 1995. We find that the probability that a facility is selected as the destination of an off-site shipment of halogenated solvent waste depends on the cost of shipping and disposal at th...

The hierarchical hub covering facility location problems are applied to distribution systems, transportation, waste disposal, treatment services, emergency services and remote communication. The problems attempt to determine the location of service providers' facilities at different levels and specify their linking directions in order to reduce costs and to establish an appropriate condition in...

in vietnam, municipal solid waste (msw) has being become increasing complex due to variety of reasons as the increasing quantity, changing composition of msw, rising public awareness and municipal administration policies among different cities and surrounding communities. there is not currently an efficient management system in place for facilities such as storage, collection, transfer, tran...

This paper presents a multi-objective optimization model for the design of a waste management system consisting of customers, transfer stations, landfills and collection vehicles. The developed model aims to simultaneously minimize the total costs, greenhouse gas emissions and the rates of energy consumption. To tackle the multiple objectives in the problem, we utilize an interactive fuzzy prog...

On-line monitoring of process and wastewater streams optimizes the control of treatment methods by providing early indications of problems that could increase discharges of hazardous compounds to the environment. On-line monitoring is important for the immediate detection and remediation of process upsets in critical streams. The waste flow to the Radioactive Liquid Waste Treatment Facility (RL...

Hospital solid waste is any waste which is generated in the diagnosis, treatment or immunization of human beings or animals or in research in a hospital [1]. Despite the enormous volumes of waste produced by health care systems and the increasing concern among scientists, waste generation has received little attention in clinical literature. The isolation of fungal species in health care solid ...

As in many developing countries the use of nuclear techniques is growing considerably in importance within the national economy of Ghana. With the operation of a nuclear research reactor, gamma irradiation facility, radiotherapy and nuclear medicine facilities in Ghana, the need to establish commensurate infrastructure for radioactive waste management has been recognized. This paper highlights ...
