Characterizing Supply Variability and Operational Challenges in an Intermittent Water Distribution Network

Optimizing Intermittent Water Supply in Urban Pipe Distribution Networks

In many urban areas of the developing world, piped water is supplied only intermittently, as valves direct water to different parts of the water distribution system at different times. The flow is transient, and may transition between free-surface and pressurized, resulting in complex dynamical features with important consequences for water suppliers and users. Here, we develop a computational ...

Characterizing and modeling network traffic variability

This paper advocates using the recently introduced Index of Variability (IDV) and a new measure, Peak Rate Variability (PRV), to characterize the variability (burstiness) in real communications network traffic over the entire range of time scales. Further, we suggest the general hyperexponential interarrival distribution as a model suitable for network traffic and evaluate the ability of the th...

Network Capacity Assessment and Increase in Systems with Intermittent Water Supply

Water supply systems have been facing many challenges in recent decades due to the potential effects of climate change and rapid population growth. Water systems need to expand because of demographic growth. Therefore, evaluating and increasing system capacity is crucial. Specifically, we analyze network capacity as one of the main features of a system. When the network capacity starts to decre...

Supply chain challenges in public distribution system

The paper aims to discuss supply chain management challenges in Public Distribution System, a food security scheme in India, based on the data collected from the stakeholders. With particular focus on supply chain strategy, we explore how the social objectives lead to supply chain design which affect system’s performance.
