Consider a Bayesian optimal design with many support points which poses the problem of collecting data with a few number of observations at each design point. Under such a scenario the asymptotic property of using Fisher information matrix for approximating the covariance matrix of posterior ML estimators might be doubtful. We suggest to use Bhattcharyya matrix in deriving the information matri...

In this work we focus on observational data and on the use of large data sets to implement an experimental design without additional runs, for an efficient use of these data, exploiting theory about optimal designs. More specifically, the proposed procedure is based on several steps and is an extension of a previous work. Furthermore, the final optimal design can be obtained discriminating betw...

The binary and ternary codes spanned by the rows of the point by block incidence matrices of some 2-designs and their complementary and orthogonal designs are studied. A new method is also introduced to study optimal codes.

this paper deals with optimal operation of a three-product dividing-wall column (dwc). the main idea is to design a control structure, through a systematic procedure for plantwide control, with an objective to achieve desired product purities with the minimum use of energy. exact local method is used to find the best controlled variables as single measurement or combination of measurements base...

We describe the phase-field method, a new approach to optimal design originally introduced in Bourdin and Chambolle, 2000; Bourdin and Chambolle, 2003. It is based on the penalization of the variation of the properties of the designs, and its variational approximation (in the sense of Γ–convergence. It uses a smooth function, the phase-field, to represent all materials involved. We describe our...

This paper presents a precise market model for a well-defined class of distributed configuration design problems. Given a design problem, the model defines a computational economy to allocate basic resources to agents participating in the design. The result of running these “design economies” constitutes the market solution to the original problem. After defining the configuration design framew...
