Error Recovery for SLA-Based Workflows within the Business Grid
Quan, Dang Minh; Altmann, Jorn; Yang, Laurence T. - Technology Management, Economics and Policy Program … - 2010
This chapter describes the error recovery mechanisms in the system handling the Grid-based workflow within the Service Level Agreement (SLA) context. It classifies the errors into two main categories. The first is the large-scale errors when one or several Grid sites are detached from the Grid...

Brand and Quantity Choice Dynamics Under Price Uncertainty
Erdem, Tulin; Imai, Susumu; Keane, Michael - Volkswirtschaftliche Fakultät, … - 2003
We develop a model of household demand for frequently purchased consumer goods that are branded, storable and subject to stochastic price fluctuations. Our framework accounts for how inventories and expectations of future prices affect current period purchase decisions. We estimate our model...

Relevant States and Memory in Markov Chain Bootstrapping and Simulation
Cerqueti, Roy; Falbo, Paolo; Pelizzari, Cristian - Volkswirtschaftliche Fakultät, … - 2013
Markov chain theory is proving to be a powerful approach to bootstrap highly nonlinear time series. In this work we provide a method to estimate the memory of a Markov chain (i.e. its order) and to identify its relevant states. In particular the choice of memory lags and the aggregation of...

IT Service Platforms: Their Value Creation Model and the Impact of their Level of Openness on their Adoption
Gebregiorgis, Selam Abrham; Altmann, Jorn - Technology Management, Economics and Policy Program … - 2012
Many IT service platforms (e.g., cloud computing platforms) are built as closed systems. They do not allow their customers to interoperate with other platforms or port their data to other platforms. As switching to different system is costly, customer of a closed IT system can be considered...
