On The Viability Of Quantitative Assessment Methods In Software Engineering And Software Services, Joseph D. Lucente Jun 2015

On The Viability Of Quantitative Assessment Methods In Software Engineering And Software Services, Joseph D. Lucente

Electronic Theses and Dissertations

IT help desk operations are expensive. Costs associated with IT operations present challenges to profit goals. Help desk managers need a way to plan staffing levels so that labor costs are minimized while problems are resolved efficiently. An incident prediction method is needed for planning staffing levels. The potential value of a solution to this problem is important to an IT service provider since software failures are inevitable and their timing is difficult to predict. In this research, a cost model for help desk operations is developed. The cost model relates predicted incidents to labor costs using real help desk …


An Inter-Domain Supervision Framework For Collaborative Clustering Of Data With Mixed Types., Artur Abdullin Dec 2013

An Inter-Domain Supervision Framework For Collaborative Clustering Of Data With Mixed Types., Artur Abdullin

Electronic Theses and Dissertations

We propose an Inter-Domain Supervision (IDS) clustering framework to discover clusters within diverse data formats, mixed-type attributes and different sources of data. This approach can be used for combined clustering of diverse representations of the data, in particular where data comes from different sources, some of which may be unreliable or uncertain, or for exploiting optional external concept set labels to guide the clustering of the main data set in its original domain. We additionally take into account possible incompatibilities in the data via an automated inter-domain compatibility analysis. Our results in clustering real data sets with mixed numerical, categorical, …
