in this paper, numerical spline-based differential quadrature is presented for solving the boundary and initial value problems, and its application is used to solve the fixed rectangular membrane vibration equation. for the time integration of the problem, the runge–kutta and spline-based differential quadrature methods have been applied. the runge–kutta method was unstable for solving the prob...

Quality function deployment (QFD) has been widely used to translate customer requirements (CRs) into engineering characteristics (ECs) in product planning and improvement. Product planning house of quality (PPHOQ) is of fundamental and strategic importance in the QFD system. Correctly determining the final priority ratings of CRs is essential in the process of constructing PPHOQ, because it wil...

Knowledge of in-the-field software operation is nowadays acquired by many software-producing organizations. Vendors are effective in acquiring large amounts of valuable software operation data to improve the quality of their software products. For many vendors, however, it remains unclear how their actual product software processes can be advanced through structural integration of such informat...

micropolar plasticity provides the capability to carry out post-failure simulations of geo-structures due to microstructural considerations and embedded length scale in its formulation. an essential part of the numerical implementation of a micropolar plasticity model is the integration of the rate constitutive equations. efficiency and robustness of the implementation hinge on the type of inte...

‎‎‎‎‎‎‎‎‎‎‎‎‎This paper aims to construct a general formulation for the shifted Jacobi operational matrices of integration and product‎. ‎The main aim is to generalize the Jacobi integral and product operational matrices to the solving system of Fredholm and Volterra integro--differential equations‎ which appear in various fields of science such as physics and engineering. ‎The Operational matr...

To improve thequalityofdecisionmaking in theprocessoperations, it is essential to implement integrated planning and scheduling optimization. Major challenge for the integration lies in that the corresponding optimization problem is generally hard to solve because of the intractable model size.

Customer integration is an integral element of the innovation process today. Yet, despite the potential for integrating external knowledge into new product development (NPD) processes, companies often fail to benefit sufficiently from customer integration. Research attributes this failure to restricted absorptive capacity, intellectual property concerns, or the ''not-invented-here'' syndrome bu...
