In this paper, a general multi-level decomposition based framework has been proposed for integration of planning and scheduling in a multi-site, multi-product plant, with applications to paper manufacturing. The problem involves complex issues relating to large-scale production in a hybrid flowshop configuration, decisions relating to minimizing trim losses, while maintaining on-time delivery o...

in this paper we introduce the notion of classical quasi-primary submodules that generalizes the concept of classical primary submodules. then, we investigate decomposition and minimal decomposition into classical quasi-primary submodules. in particular, existence and uniqueness of classical quasi-primary decompositions in finitely generated modules over noetherian rings are proved. moreover, w...

The Global Navigation Satellite System-Reflections (GNSS-R) signal has been confirmed to be used retrieve sea level height. At present, the GNSS-Interferometric Reflectometry (GNSS-IR) technology based on least square method process signal-to-noise ratio (SNR) data is restricted by satellite elevation angle in terms of accuracy and stability. This paper proposes a new GNSS-IR model combining va...
