In this study, a bi-objective multi-state redundancy allocation problem of series-parallel systems consisting of some serial subsystems, each with non-repairable components in parallel, is investigated. Furthermore, due to uncertainty involved, both the performance rates and the availabilities of components are considered fuzzy. In addition, two strategies of all-unit and incremental-quantity d...

Low nocturnal temperature (LNT) is a major constraint for protected tomato production in China during winter and spring, which leads to phosphorus (P) deficiency symptoms. The soil P fractions reflect availability. foliar root the adaptation strategies of tomatoes LNT. However, relationship between plant under LNT not well understood. Therefore, we conducted 40-day indoor incubation experiment ...

Abstract Uncertainties from hydrological and meteorological environments constantly pose disturbances to water sustainability. Programming under such uncertainties aims at finding solutions this risky condition. From the sight of uncertain availability, paper builds a life cycle model reduce risks inappropriate estimations availability within river basin incorporates results in robust programmi...

Phosphorus (P) is among the most intractable constraints on plant fertility, particularly in acidic soils with high P fixation capacities. The effects of nutrient limitation and adaptive strategies plants infertile are central topics ecology. development tree cultivars greater use efficiency (PUE), defined as ability a to grow be productive reduced availability, would substantially improve fore...

Plants plastically change their morphological and physiological traits in response to environmental changes, which are accompanied by changes in endogenous levels of phytohormones. Although roles of phytohormones in various aspects of plant growth and development were elucidated, their importance in the regulation of biomass allocation was not fully investigated. This study aimed to determine c...
