Model‐Based Systems Engineering in Space Applications: A Comprehensive Literature Review
ABSTRACT The growing complexity of space engineering is driving the demand to embrace the adoption of Model‐Based Systems Engineering (MBSE). Although the MBSE is well‐practiced in the space industry, the level of effort and need required to obtain the benefits of MBSE vastly differ across enterprises; this disparity presents a significant challenge to

Fuzzy Failure Modes, Effect and Criticality Analysis on Electromechanical Actuators
The electromechanical servo is the preferred aviation servo actuator system now. EMA (electromechanical actuators), especially EMA of airplanes, will inevitably occur a variety of faults. FMECA (Failure Modes, Effect and Criticality Analysis) is commonly

Adapted FMECA for Supporting Maintenance Actions
In a Navy ship the knowledge of the equipment’s and systems state are a pillar and a necessity for operation success. Nowadays equipment’s are monitored with multiple sensors, and data are storage and processed through automatic systems. However, the data is not always useful, and most of the times it is never putted into useful data.
