Module development process

In a third step, a sensitivity analysis is carried out. Here, the defined key modules are assessed with regard to their costs and manufacturability. Furthermore, other important factors as, for example, resource availability, technological requirements and the potential for outsourcing parts of the manufacturing process are included in the analysis. Moreover, the modules suitability for assembly is the subject of the sensitivity analysis. If the results of the analysis indicate any insufficiency, the module development process has to be repeated. 

In the past, most simulation programs available to designers were of the sequential-modular type. They were simpler to develop than the equation based programs, and required only moderate computing power. The modules are processed sequentially, so essentially only the equations for a particular unit are in the computer memory at one time. Also, the process conditions, temperature, pressure, flow-rate, are fixed in time. 

Recent Developments in rugged FTIR Modules for Process Applications... 

The use of feedback-control techniques to modulate combustion processes in propulsion systems has recently received extensive attention [1-3]. Most of the previous studies involved direct implementation of existing control methods designed for mechanical devices, with very limited effort devoted to the treatment of model and parametric uncertainties commonly associated with practical combustion problems. It is well established that the intrinsic coupling between flow oscillations and transient combustion responses prohibits detailed and precise modeling of the various phenomena in a combustion chamber, and, as such, the model may not accommodate all the essential processes involved due to the physical assumptions and mathematical approximations employed. The present effort attempts to develop a robust feedback controller for suppressing combustion instabilities in propulsion systems. Special attention is given to the treatment of model uncertainties. Various issues related to plant... 

In a mature software development environment, software is developed as individual components or small units. Each unit is tested individually and integrated with other units to form a module. The accurate implementation of each module is achieved by following the technical design specification deliverable. The output of the software development process is an assembled system. 

Process and organisational solutions of design developments shall ensure maximum independence of MHR-T modules during operation and in all possible accidents with radiation emission/release. Links between MHR-T modules and between these modules and process lines and overall infrastructure (control, support and auxiliary systems) shall be determined at the design stage. 

Standardized directory structures for source code, documentation hies, hnal executables, conhguration hies, and model inputs/outputs allow tracking the software development process and also help in easily integrating multiple, independently developed modules. Standardized directory structures allow easy detection of con-hicts in the names of functions, scripts, or conhguration hies.
