Consumers often infer quality information from prices and rely on their reference prices. This paper incorporates both behavioral regularities nto the classic utility function. The analytical investigation reveals five qualitatively different types of consumers, three of which are relatively new o modeling literature. The authors test the model’s theoretical insights using a new experimental me...

Nowadays, due to the increasing energy demand in different industry, agriculture, and household sectors, great importance is attached portfolio generation/consumption macrolevel planning. A viable approach power generation planning environmental assessment of process. This study employs life cycle based on Eco-Indicator 99 methodology which analyzes midpoint endpoint impacts. Energy impact eval...

The source location problem is a problem of computing a minimum cost source set in an undirected graph so that the connectivity between the source set and a vertex is at least the demand of the vertex. In this paper, the connectivity between a source set S and a vertex v is defined as the maximum number of paths between v and S no two of which have common vertex except v. We propose an O(d∗ log...

Today, the on-demand transportation is used for elderly and disabled people for short distances. Each user provides a specific demand: a particular ride from an origin to a destination with hard time constraints like time windows, maximum user ride time, maximum route duration limits and precedence. This paper deals with the resolution of these problems (Dial-a-Ride Problems – DARP), including ...

In some operational circumstances a fast evaluation of landfill leachate anaerobic treatability is necessary, and neither Biochemical Methane Potential nor BOD/COD ratio are fast enough. Looking for a fast indicator, this work evaluated the anaerobic treatability of landfill leachate from São Carlos-SP (Brazil) in a pilot scale Anaerobic Sequence Batch Biofilm Reactor (AnSBBR). The experiment w...

The selection of reasonable locations for urban wastewater treatment plants (WWTPs) is significant in controlling water pollution. However, most current WWTP location models focus only on population density, industrial zone scale and geographic elements, while ignoring pollution local socio-cultural indicators. We propose a novel indicator system from RS/GIS data to select WWTPs Phnom Penh avoi...

Studies have shown stormwater runoff is a contributor to elevated indicator bacteria concentrations in surface waters. These elevated concentrations may indicate a heightened human health risk and lead to water quality violations as concentrations exceed regulatory standards. Total Maximum Daily Loads (TMDLs) are commonly established for indicator bacteria, requiring modeling and watershed plan...

A method for forecasting the number of parts shipments is proposed for build-to-order products using pre-sales estimate information as a leading indicator. Since the target number of parts shipments changes irregularly and over a short lifecycle, it is difficult to forecast with conventional methods. The method uses Kalman filter to correct for the noise associated with the leading indicator an...

In the database area, elasticity of cloud computing has required data systems to increase and decrease their resources on demand. However, traditional benchmark tools for data systems are not sufficient to analyze some specificities of these systems in a cloud. New metrics for elasticity are needed to provide an indicator both from consumer and provider perspective. In this work we present a se...
