supply chain network   receding horizon control demand move suppression term   supply chain networks are interconnection and dynamics of a demand network. example subsystems, referred to as stages, include raw materials, distributors of the raw materials, manufacturers, distributors of the manufactured products, retailers, and customers. the main objectives of the control strategy for the suppl...

due to uncertain nature of wind and photovoltaic power units, the participation of this units in electricity markets is subjected to significant deviation penalties. this issue leads to despondency or even admission of these units in the competitive environment. with regard to this fact that the low deviations are available when predictions are performed in a short-term horizon and also distrib...

purpose: the aim of the present study was to determine theeffectiveness of group hope therapy on the time horizon andoptimism of divorced women 25-40 years old in tehran whoreferred to a counseling center. materials and method: 30divorced women were selected randomly and were assignedat two experimental and control groups. group hope therapywas held for 8 sessions of 2 hour. group hope therapy ...

In this paper, we propose some improvements for the problem of time series prediction with neural networks where a medium-term prediction horizon is needed. In particular, the ionospheric prediction service of the french Centre National d' Etudes des T el ecommunica-tions needs a six-month ahead prediction of a sunspots related time series which has a strong innuence on wave propagation in iono...

The significance of the basic idea implicit in the moving horizon control (MHC) has been recognized a long time ago in the operations management literature as a tractable scheme for solving stochastic multi period optimization problems, such as production planning and supply chain management, under the term moving horizon. In this paper, a moving horizon controller with move suppression term us...

In this work, we describe short-term and medium-term scheduling for a largescale industrial continuous plant. For medium-range scheduling, two subproblems are solved using a rolling horizon based decomposition scheme. An upper-level model is used to find the optimal number of products, and length of the time horizon to be considered for solving the lower level short-term scheduling problem. At ...

This paper proposes a novel technique for solving generation scheduling and ramp rate constrained unit commitment. A modified objective function associated with a new start-up cost term is introduced in this paper. The proposed method is used to solve generating scheduling problem satisfying SRR, minimum up and down time as well as ramp rate constraints. Two case studies are conducted to imp...
