Agile–Stage Gate Management (Asgm): Npd Implementation Practices From Global Firms Developing Complex, Physical Products, John J. Salvato
Agile–Stage Gate Management (Asgm): Npd Implementation Practices From Global Firms Developing Complex, Physical Products, John J. Salvato
Dissertations, Master's Theses and Master's Reports
Stage Gate Management (SGM) has been used successfully by global organizations to direct the New Product Development process (NPD) for years, recently a new variant of this venerable approach has emerged. Researchers and firms have begun to intersperse elements of Agile, as popularized for the development of software, to create an Agile – Stage Gate Management (ASGM) hybrid NPD framework. Agile practitioners believe in process waste reduction, an intense focus on customers, and the creation of nimble entrepreneurial project teams, which, for software products, has positively impacted development time to market, resource utilization, and market success, more generally, improved business …

Modelling And Analysis Of Chevy Volt Gen Ii Hybrid Vehicle In Electric Mode, Kaushik Surresh
Dissertations, Master's Theses and Master's Reports
The technical report discusses the high fidelity modelling of the powertrain of Chevy Volt Gen II Hybrid Vehicle in the Electric Mode. The overall objective of the powertrain model was to predict total energy consumed within 5% of experimental data for different drive cycles in Charge Depleting Mode. The following powertrain elements were modelled in Matlab and Simulink using parameters and performance maps provided by General Motors: battery, E-Motor, TPIM power electronics, transmission auxiliary pumps and spin losses.
An electric circuit based dynamic model of the Li-ion battery was developed. Static models of the E Motor, TPIM inverter, transmission auxiliary …

Physical Modeling Of Lithium-Ion Aging For Automotive Applications, Anurag Kamal
Dissertations, Master's Theses and Master's Reports
This thesis extends the full-scale electrochemical model for a Lithium-ion battery based on the porous electrode theory to incorporate aging mechanisms of solid electrolyte interface formation, cyclic electrode degradation, and lithium plating during overcharge, automotive vibrations, mechanical stress, and cell temperature, as reported in the existing literature. Further, the thesis presents the scope of the parameters used in the model to enable designers to extend the equations for new mechanisms and variability of other parameters.
An increased set of equations makes the complexity of the model even higher, and it would be very computationally complex to simulate this model. This …
