this research aims at presenting a consolidated model of data envelopment analysis (dea) technique and value engineering to select the best manufacturing methods for gate valve covers and ranking the methods using topsis.to do so, efficiency evaluation indices were selected based on the value engineering approach and different manufacturing methods were evaluated using dea technique.finally, ef...

We discuss in this paper the application of the methods of operation research (OR) to tackling various design problems of Automated Guided Vehicle Systems (AGVS) . We present a selective review of tile literature on applying OR to aid AGVS planning eind clesign . This study can make engineers aware of the problems commonly encountered in AGVS design and the potential use ofOR for solving these ...

In reliability engineering, component importance measures are used to prioritise components in a system for purposes such as reliability improvement and maintenance planning. Existing importance measures have paid little attention to the costs incurred by maintaining a system and its components within a given time period. Cost-effectiveness analysis, however, is critically important in increasi...

All Software Engineering (SE) processes include steps where several alternatives call for decisions. However, in many cases, the choice is intuitive and thereafter hazardous with unpredictable consequences. On the other side, the operational research domain has produced many methods that could be adequately used in these situations. Using these methods should facilitate the decision making acti...

Software Engineering (SE) researchers are increasingly paying attention to organizational and human factors. Rather than focusing only on variables that can be directly measured, such as lines of code, SE research studies now also consider unobservable variables, culture trust. To measure latent scholars have adopted Partial Least Squares Structural Equation Modeling (PLS-SEM), which is one mem...
