An easy to implement and robust design control method dedicated to multi-cell converters using inter cell transformers

Robust inter and intra-cell layouts design model dealing with stochastic dynamic problems

In this paper, a novel quadratic assignment-based mathematical model is developed for concurrent design of robust inter and intra-cell layouts in dynamic stochastic environments of manufacturing systems. In the proposed model, in addition to considering time value of money, the product demands are presumed to be dependent normally distributed random variables with known expectation, variance, a...

Robust optimization of a mathematical model to design a dynamic cell formation problem considering labor utilization

Cell formation (CF) problem is one of the most important decision problems in designing a cellular manufacturing system includes grouping machines into machine cells and parts into part families. Several factors should be considered in a cell formation problem. In this work, robust optimization of a mathematical model of a dynamic cell formation problem integrating CF, production planning and w...

A weighted metric method to optimize multi-response robust problems

In a robust parameter design (RPD) problem, the experimenter is interested to determine the values of con-trol factors such that responses will be robust or insensitive to variability of the noise factors. Response sur-face methodology (RSM) is one of the effective methods that can be employed for this purpose. Since quality of products or processes is usually evaluated through several quality ...

Analytic Design Method for (Integrated-) Transformers of Resonant Converters using Extended Fundamental Frequency Analysis

The series-parallel resonant converter and its magnetic components are analysed by fundamental frequency techniques. The proposed method allows an easy design of the integrated transformer and the calculation of the losses of all components of the converter. Thus, an optimisation of the whole converter system – minimising either the volume and/or the losses of the converter (upper temperature i...
