We consider a periodic review, single-item, deterministic demand inventory model under non-stationary supply availability which has an all-or-nothing type of structure. Supply availability information is provided by the supplier which we refer as advance s ...
Mode choice is influenced by quantitative aspects such as cost and time, but importance should be given to qualitative aspects such as people's attitudes or perceptions towards the different modes as well. These latent characteristics can be integrated int ...
We develop an iterative diffusion mechanism to optimize a global cost function in a distributed manner over a network of nodes. The cost function is assumed to consist of a collection of individual components, and diffusion strategy allows the nodes to coo ...
In this paper we address the issue of network cost efficiency for live streaming peer-to-peer systems. We formalize this as an optimization problem, which features a generic cost function. The latter is appropriate to capture not only ISP-specific link wei ...
The semi-synchronous model is an important middle ground between the synchronous and the asynchronous models of distributed computing. In this model, processes can detect (timeout) when other processes fail. However, since detection is done by timing out, ...
The reunification of 10 faculty libraries inside the new Rolex Learning Center at EPFL was a perfect opportunity to rethink which collections should be put forward in an environment that is organized primarly around the working and living space of the user ...
This paper investigates the limit behavior of Markov decision processes made of independent objects evolving in a common environment, when the number of objects (N) goes to infinity. In the finite horizon case, we show that when the number of objects becom ...
The various actors in the regulated industries relate to each other within a broader institutional framework, i.e., by way of formal and informal rules. An important role in the implementation of liberalization processes is given to regulation and thus to ...
The reunification of 10 faculty libraries inside the new Rolex Learning Center at EPFL (Lausanne, Switzerland) was a perfect opportunity to rethink which collections should be put forward in an environment that is organized primarily around the working and ...
Lignocellulosic ethanol is expected to be commercialised during the next decade as renewable energy for transport. Competiveness with first generation bioethanol and with gasoline is commonly considered in techno-economic analyses for commercial stage. Sev ...
