<span>The paper presents a new step-by-step procedure for constructing navigation satellite motion model. At the first stage of procedure, parameters radiation pressure model are estimated using maximum likelihood method. The statistic estimator based on continuous-discrete adaptive unscented Kalman filter is proposed solar estimation. Step-by-step scheme filtering algorithm used software...

Abstract We present a formulation and numerical algorithm to extend the scheme for gray radiation magnetohydrodynamics (MHD) developed by Jiang include frequency dependence via multigroup approach. The entire space can be divided into an arbitrary number of groups in lab frame, we follow time-dependent evolution frequency-integrated specific intensities along discrete rays inside each group. Sp...

Models that aim to optimize the design of supply chain networks have gained more interest in the supply chain literature. Mixed-integer linear programming and discrete-event simulation are widely used for such an optimization problem. We present a hybrid approach to support decisions for supply chain network design using a combination of analytical and discrete-event simulation models. The prop...

This paper presents a multiobjective continuous covering location problem in fuzzy environment. Because of uncertain covering radius, possibility of covering concept is introduced.Since, the uncertainty may cause risk of uncovering customers; the problemis formulated as a risk management model. The presented model is an extension of the discrete covering location models tocontinuous space. Two ...
