Petri net workflow modeling for digital publishing measuring quantitative dependability attributes | Posted on:2008-07-28 | Degree:M.S | Type:Thesis | University:University of Puerto Rico, Mayaguez (Puerto Rico) | Candidate:Chaparro-Baquero, Gustavo Adolfo | Full Text:PDF | GTID:2448390005953313 | Subject:Computer Science | Abstract/Summary: | | This work presents the concept of workflow modeling using Generalized Stochastic Petri Nets (GSPN) for the Digital Publishing business process and how the attributes of dependability are measured in a quantitative form. In this approach, these are measured from the workflow model itself instead from a combinatorial model adapting some methodologies and strategies for combinatorial model build to the creation of the workflow process definition, improving the analysis of a workflow model. This approach will lead to make the model more versatile. Contrasting the analysis provided in other research projects, our work proposes an analysis of quantitative dependability over a workflow model, and not only an analysis of its structure and performance.; Publishing market competence is highly close and prices are regulated by the market itself with a very little gap between cost and profit. How reliable or, even more, trustable a print-shop could be to its client means to increase or decrease that gap of profitableness. Applying these measure concepts to the Digital Publishing pre-press process provides a better workflow management in this area than current procedures, since this process is based on its trustworthiness.; Modeling the business process of Digital Publishing using the theory of WorkflowNets and translating them into GSPN, we obtain a Quantitative Dependability WFnet based Model (QDWM). The methodology for creating a QDWM, which allows workflow modeling measuring quantitative dependability attributes is introduced, and the results for a case study on preflight and ripping stages of the Digital Publishing workflow are presented. A contrast between results from a Fault Tree Model (Combinatorial Model) and a QDWM, shows that the later is able to measure quantitative dependability attributes maintaining its main intended function: to be a workflow model. | Keywords/Search Tags: | Workflow, Model, Quantitative dependability, Digital publishing, Attributes, Process | | Related items |
