How to evaluate usage of media flow systems : and how to use statistical metrics for rule based control.

Abstract: Evaluation of complex systems is as necessary now as ever.To conduct a successful evaluation, in other words an evaluationthat shows something interesting and perhaps unknownabout the system, one should be structured and planwell. This degree project used the goal question metric approachto conduct an evaluation of how the system MAMA,a media flow system used for television broadcasting services,was used during one year. By using the goal questionmetric approach it was possible to specify goals, questionsand metrics that provided data interesting for system operators.The model facilitated the planning phase of the evaluationof MAMA and clearly showed how one keeps a goodstructure throughout an evaluation. This degree projectreport may serve as a guide of how to conduct a fruitfulevaluation of any system. Automation and dynamic flowcontrol are in high demand when human workers are expensive.A natural step in modernising flow systems is tomake more flows automated and dynamic. A suggestion ofhow to set the time of deadline of an order was produced.By constructing a fuzzy logic controller it was found theoreticallypossible to obtain reasonable results. The fuzzylogic controller that was suggested, aims to mimic the decisionsthat otherwise would be made by human operators.The suggested controller was believed to be able to providea reasonable deadline, with the restrictions in the system.
