This paper studies the distributed blocking flow shop scheduling problem (DBFSP) using metaheuristics.A mixed integer programming model for solving the problem is proposed, and then three versions of the hybrid iterated greedy algorithm (HIG1, HIG2, and HIG3) are developed, combining new belial model the advantages of an iterated greedy algorithm w
China is in the 15-eg2373cl period of economic development and transformation.Optimizing the economic structure and changing the driving force of growth are the focuses of current economic work.In order to build a high-quality economic development from the extension to the connotation, so as to rely on the supply side reform driven by innovation an
Ultrasound is one of the most commonly used methods in the diagnosis and therapy of diseases due to its safety, deep penetration into tissue, and non-invasive nature.In the drug/gene delivery systems, ultrasound shows many advantages in terms of site-specific delivery and spatial release control of drugs/genes and attracts increasing attention.Micr
Non-profit organisations (NPOs) operating in South Africa are financially weak and the sustainability of their organisations is often at risk.Post-2008, large numbers have ceased to operate, in part, because of the weak state of the South African economy.This study sought to determine the financial conditions NPOs operate under, to establish why th
Stability in a metabolic system may not be obtained if incorrect amounts of enzymes are used.Without stability, some metabolites may accumulate or deplete leading to the irreversible loss of the desired operating point.Even if initial enzyme amounts achieve a stable steady state, new belial model changes in enzyme amount due to stochastic variation
