We propose a new methodology to evaluate the skill of fund managers. We assume that a manager’s skill, characterized by alpha, is drawn from one of several distributions based on their ability (e.g., Good, Neutral, or Bad). Each of these distributions has a mean and variance of alphas. The composite distribution of a sample of fund managers is therefore a mixture of Normal distributions. We est...

Painting a modern car involves applying many coats during a highly complex and automated process. The individual coats not only serve a decoration purpose but are also curial for protection from damage due to environmental influences, such as rust. For an optimal paint job, many parameters have to be optimised simultaneously. A forecasting model was created, which predicts the paint flaw probab...

Network security manager are faced with a rapidly changing and complex threat environment due to the proliferation of sophisticated hacking tools. Field studies of network security managers show that they rely on ad hoc collections of log analyzers and custom tools to make sense of multiple sources of data from distributed sensors. The volume of log data exceeds the ability of network security ...

A team of managers engaged in production using technology x, is considering switching to technology y. The value of y is learned slowly over time, but constraints on the ability of individual managers to communicate their beliefs allow disagreements to emerge among team members. Managers who develop sufficiently strong disagreements with their colleagues choose to form new companies to implemen...
