Several papers have been presented in the last years regarding the design of reliable sensor networks. In all these papers, the system reliability was maximized, constrained by a fixed number of sensors. In these models, the cost has played an indirect unclear role. A minimum cost model for the design of reliable sensor networks is presented in this paper. The connections with previous models a...

We consider a production-inventory system that consists of an input-generating installation, a production unit and L intermediate buffers. It is assumed that the installation transfers the raw material j ∈ {1, . . . , L} to buffer Bj, and the production unit pulls the rawmaterial j ∈ {1, ..., L} from buffer Bj. We consider the problem of the optimal preventive maintenance of the installation if...

Time-domain equalizers (TEQ) are used in the discrete multitone (DMT) transceivers in order to reduce the duration of the overall response of the transmission system, so that a shorter-length cyclic prefix could be used. The optimum TEQ is the one that results in maximum bit allocation to each block of DMT. However, the optimum design of TEQs turns out to be a very difficult task. In this paper...

A numerical method is proposed for constructing an approximation of the Pareto front of nonconvex multi-objective optimal control problems. First, a suitable scalarization technique is employed for the multi-objective optimal control problem. Then by using a grid of scalarization parameter values, i.e., a grid of weights, a sequence of single-objective optimal control problems are solved to obt...

An optimal control problem of an economic system with two criteria is considered in the paper. The Solow model of economic growth is used. Rate of consumption is a control variable, quality vector criterion is a discounted utility in the long-term and near-term. Pontryagin’s maximum principle is applied to the single criteria problem with weighted sum of two functionals. The existence of the so...

This study considers three alternative sources of information about volatility potentially useful in predicting daily asset returns: daily returns, intraday returns, and option prices. For each source of information the study begins with several alternative models, and then works from the premise that all of these models are false to construct a single improved predictive distribution for daily...

This paper deals with the estimation of the lognormal-Pareto and the lognormal-Generalized Pareto distributions, for which a general result concerning asymptotic optimality of maximum likelihood estimation cannot be proved. We develop a method based on probability weighted moments, showing that it can be applied straightforwardly to the first distribution only. In the lognormal-Generalized Pare...

Cost optimization will be essential to the economic viability of future many-robot systems. Unfortunately, cost-optimal design will often depend sensitively on the performance and costs of candidate sensor and other components, and on both explicit mission-specific and implicit common sense application requirements. The development of a standardized integration architecture providing multi-leve...

The economic literature on “optimal income taxation” addresses the question of how to design tax and transfer policy so as to maximize “social welfare,” which is some function of the wellbeing of all members of society. It clarifies how the social-welfare-maximizing policy depends on one’s philosophy of distributive justice, and on empirical evidence about the behavioral response to incentives,...

This work deals with the multicriteria cost-environment design of multiproduct batch plants, where the design variables are the equipment item sizes as well as the operating conditions. The case study is a multiproduct batch plant for the production of four recombinant proteins. Given the important combinatorial aspect of the problem, the approach used consists in coupling a stochastic algorith...
