A robust state feedback design subject to placement of the closed loop eigenvalues in a prescribed region of unit circle is presented. Quantitative measures of robustness and disturbance rejection are investigated. A stochastic optimization algorithm is used to effect trade-off between the free design parameters and to accomplish all the design criteria. A numerical example is given to illustra...

Acceptance control charts (ACC), as an effective tool for monitoring highly capable processes, establish control limits based on specification limits when the fluctuation of the process mean is permitted or inevitable. For designing these charts by minimizing economic costs subject to statistical constraints, an economic-statistical model is developed in this paper. However, the parameters of s...

Abstract To design a more robust artifact, an artifact based on rationale analysis is pivotal. Errors in previous rationales that led to the degradation of robustness past provide valuable knowledge towards improving design. However, methods for exposing and analysing errors remain unclear. This paper proposes structured method logical structuring. provides well-constructed means identifying fr...
