This paper proposes a bi-objective reliable supply chain network design that immunizes the network against different sources of uncertainties. In this regard, scenario based stochastic programming method is applied to model different disruption scenarios affecting accurate performance of network stages. Also, reliable and unreliable facilities are suggested for lessening vulnerability of networ...

The advent of new antiretroviral medicines means that the effects of HIV can now be curbed, but only one in twenty infected people have so far benefited. For those living in developing countries, the new treatments are practically unattainable. Governments, UNAIDS and pharmaceutical companies recognise this only too well and have rethought established assumption in order to try and overcome the...

Energy storage and distribution is an increasingly important problem as renewable (and generally unreliable) energy sources supply more of our power needs. In this extended abstract we consider a simple network of energy suppliers, consumers and buffers modelled as fluid queues. Analytical evaluation of networks of fluid queues is hard as even tandem networks do no have a product form solution....

India is the second populous country in the world with more than 70% of the population living in rural area, 60% of India’s 1.1 billion populations living off agriculture which contributes to 17% of the Indian economy. The main resource for the agriculture is timely and adequate supply of water and electricity. Nearly 20% of the farmers in India are dependent on electric water pumps for irrigat...

The aim of this paper is twofold. First, it discusses how the functioning and performance of food chains are affected by the way stakeholders are embedded in the chains, by the coordination modes, and by the kind of governance. Second, by depicting six relevant agro-food chains, attention is raised on the kind of the stakeholders that participate in the chain and on the role of each with a spec...

This paper considers a monopolistic manufacturer that makes supplier selection and ordering decisions in a setting in which suppliers are unreliable. We find that the manufacturer’s optimal decision to diversify orders across multiple suppliers might not only arise as a result of managing supply risk, but it could also be due to the concavity of the manufacturer’s revenue function or due to the...

RFID is one of the emerging technologies for a wide-range of applications, including supply chain and asset management, healthcare and intruder localization. However, the nature of an RFID data stream is noisy, redundant and unreliable, making it unsuitable for direct use in applications. In this paper, we propose specific RFID Online Filtering and Uncertainty Management techniques that operate...

The authors examined the demand for clean drinking water using treatment behaviors in Kathmandu, Nepal. Water supply is inadequate, unreliable and low quality. Households engage in several strategies to cope with the unreliable and poor quality of water supplies. Some of the major coping strategies are hauling, storing, and point-of-use treatment. Boiling, filtering, and use of Uro-guard are so...
