In this study, we propose an improved iterated greedy algorithm for solving the distributed permutation flowshop problem, where there is a single robot in each factory and the makespan needs to be minimized.In the problem considered, the robot is used to transfer each job from the predecessor machine to the successor machine.A blocking constraint b
The heavy reliance of most global aquaculture on the ambient environment suggests inherent vulnerability to climate change effects.This review explores the potential effects of climate change stressors on aquaculture biology and resources needed to support decision-making for vulnerability assessment, planned adaptation, and strategic research deve
Abstract In the present study aims to produce high-strength fiber concrete containing microsilica and metakaolin.Eight concrete mixing samples have been defined.The samples include the control concrete with ordinary Portland cement, replacing 10 percent of the weight of cement with microsilica.The amount of Ash Catchers microsilica was kept constan
Early infant HIV diagnosis is challenging in sub-Saharan Africa, particularly in rural areas where laboratory capacity is limited.Specimens must be transported to central laboratories for testing, leading to delays in diagnosis and initiation of antiretroviral therapy.This study was undertaken in rural Zambia to measure the turnaround time for conf
