Quality function deployment is a well-known customer-oriented design procedure for translating the voice of customers into a final production. This is a way that higher customer satisfaction is achieved while the other goals of company may also be met. This method, at the first stage, attempts to determine the best fulfillment levels of design requirements which are emanated by customer needs. ...

Propositional satisfiability (SAT) problem is fundamental to the theory of NPcompleteness. Indeed, using the concept of ”polynomial-time reducibility” all NPcomplete problems can be polynomially reduced to SAT. Thus, any new technique for satisfiability problems will lead to general approaches for thousands of hard combinatorial problems. In this paper, we introduce the incremental propositiona...

The use of vector valued performance index as a performance measure in the design of optimal control systems has invited much attention from researchers in the field of control engineering. The problem is of practical significance as the system presents an optimal solution for multiple criteria optimal control problems. A general performance index is defined in the form of a norm which can be e...

A black-box solver for the solution of nonlinear functional equations is a compromise of exibilty, eeciency and stability of the algorithms. We will present a general form of functional equation, a general error indicator and the eecient interaction of the error indicator and the Newton-Raphson iteration during the solution of the problem arising from the discretization by mixed nite element me...
