Individuals are distinguished by their remaining lifetimes, which regulated the interplay between inexorable running time and individual's nourishment history. A food-limited environment induces intraspecific competition henceforth carrying capacity medium may be finite, often emulating qualitati...

Abstract With the increase of number modern equipment, expansion equipment scale, and requirements actual combat for long-term standby duty, role significance spare parts support scheme in life cycle system gradually become prominent. Taking electronic as research object, this paper analyzes relative changes between utilization rate fill under different composition scales. It introduces strateg...
