To make paper, machines spray wet pulp on a moving screen and extract the water from it by squeezing it between rollers, before drying it using heat and rolling it on reels as finished product. The water extracted in the squeezing process is removed by a continuous roll of fabric called a felt. There are typically three felts on a paper machine. Felts wear out over time, and therefore must be r...

Recent years increase in organizations’ dependence on information technology has ushered in changing roles for IT departments and IT governance alike. Instead of being primarily focused on the continuous and cost efficient maintenance and support of existing resources, there is a need for a more balanced take on IT Governance which calls for an ambidextrous approach. This involves an increased ...

This paper presents evidence on the impact of managers on cost efficiency in banking. Stochastic frontier analysis is applied to a unique Finnish data set. The paper finds that manager age and education have strong yet complicated effects. University education enhances efficiency if the manager is running a large bank. Managing director changes are systematically followed by efficiency changes....

e-Learning has opened a multitude of possibilities for teaching and learning. As the market matures there is a demand for more effective and cost-efficient learning interventions that meet the learning needs of the diverse learner population. Currently, however, very few teaching attempts have been made to match the pedagogical styles underlying e-Learning interventions to students’ diverse lea...

In this paper a new approximate method for the computation of outage probabilities in a mobile radio environment is proposed. It allows one to evaluate the performance of a mobile radio system in the presence of fading, in a very fast and accurate way, while maintaining a very good flexibility as to the application to different network environments. Coding is also considered as a possible choic...

This paper proposes an integrated analyticd/simulation approach for designing an automated guided vehicle system (AGVS) which consists of AGVs, machines with input buffers and a dispatching station in a just-in-time (JIT) envkonment. The objective is to determine the number of AGVs, the input buffer capacities and locations of the machines that minimize a cost function under the constraint that...

Background. In current economic downturn, industries have to set good control on production cost, tomaintain their profitmargin.Maintenance department as an imperative unit in industries should attain all maintenance data, process information instantaneously, and subsequently transform it into a useful decision. Then act on the alternative to reduce production cost. Decision Making Grid model i...
