The purpose of this paper is to develop a differentiated approach to the cost management tool, Total Cost of Ownership (TCO). Existing TCO related literature has investigated the tool from a focal buyer perspective and has consequently neglected to study TCO from an inter-organisational perspective. Based on empirical data, this paper develops a differentiated approach to the use of TCO consist...

Machine involvement has the potential to speed up language documentation. We assess this potential with timed annotation experiments that consider annotator expertise, example selection methods, and suggestions from a machine classifier. We find that better example selection and label suggestions improve efficiency, but effectiveness depends strongly on annotator expertise. Our expert performed...

Operators are adopting end-to-end Service Delivery Platforms (SDPs) to increase service revenue growth and retain customers. They require these additional SDP enablers to achieve efficient service lifecycle management. Rapid rollout, operation and retirement of services are necessary to optimise service revenues. Historical operator experiences clearly highlight the significant risks associated...

This paper examines the effect of geographic and industrial diversification on firm value for a sample of 1,914 corporations from 18 countries. Our results indicate that both geographic and product diversification destroy value at high levels of diversification, suggesting that agency and influence costs arising from the increased complexity outweigh the benefits of diversification at high degr...

This paper reflects the results of phase I of our study on the total cost of ownership (TCO) of open source software adoption. Not only have we found TCO to be an intriguing issue but it is contentious, baffling and each company approaches it in a distinctive manner (and sometimes not at all). In effect it is a conundrum that needs unpacking before it can be explained and understood. Our paper ...

T he idea of green high-performance computing (HPC) has been gaining traction over the past fi ve years. In November 2008, the Green 500 list (www.green500.org) was introduced to “raise awareness about power consumption, promote alternative total cost of ownership performance metrics, and ensure that supercomputers only simulate climate change and not create it.” The Green 500 lists the world’s...

In this study, we propose an integrated approach that combines Bayesian Networks and Total Cost of Ownership (TCO) to address complexities involved in selecting an international facility for a manufacturing plant. Our goal is to efficiently represent uncertain data and ambiguous information, and to unite them to improve the quality of the decisions. Bayesian Networks provide a framework to elic...

Online Reputation Systems would help mitigate the information asymmetry between clients and providers in Cloud Computing Markets. However, those systems raise two main drawbacks: the disagreement for assuming the cost of ownership of such services and their vulnerability to reputation attacks from dishonest parties that want to increase their reputation. This paper faces both problems by descri...

To regain market share in the competitive jet engine business, Pratt & Whitney has focused renewed emphasis upon cost reduction in engine development and manufacturing. Employing improved cost estimating techniques is complementary to achieving a reduction in total manufacturing cost. An increased awareness of relevant cost drivers will facilitate tradeoff decisions among competing alternatives...

This paper presents an eight-year record (July 1995June 2003) of ozone profiles and tropospheric column ozone (TCO) retrieved from GOME ultraviolet radiance spectra using the optimal estimation technique, including detailed treatments of wavelength and radiometric calibrations and forward radiative transfer modeling. The agreement with Stratospheric Aerosol and Gas Experiment (SAGE) data is usu...
