Purpose – The purpose of this paper is to develop a guideline of the control procedure and tools depending on dominance pattern. In Lean Six Sigma (LSS) implementation, the control phase plays a vital role in sustaining the gains achieved from the improvement phase. The process control schemes...

Recently some studies have been carried out on RCCI (reactivity controlled compression ignition) engines; however, they routinely used the “one factor at a time” approach, which may neglect interactions among the manipulated factors. This paper reports the use of a more effective approach...

We report on using Design of Experiments (DoE) methods to study the influence of the gas diffusion layer (GDL) material on Polymer Electrolyte Membrane Fuel Cell (PEMFC) performance. We applied DoE methods to discern and quantify the effect of a micro-porous layer (MPL) for the first time. Two...
