Multi-compartment Model - Assumptions

Assumptions

Multi-compartment modeling requires the adoption of several assumptions, such that systems in physical existence can be modeled mathematically:

  • Instant homogeneous distribution of materials or energies within a "compartment."
  • The exchange rate of materials or energies among the compartments is related to the densities of these compartments.
  • Usually, it is desirable that the materials do not undergo chemical reactions while transmitting among the compartments.
  • When concentration of the cell is of interest, typically the volume is assumed to be constant over time, though this may not be totally true in reality.

Most commonly, the mathematics of multi-compartment models is simplified to provide only a single parameter--such as concentration--within a compartment.

Famous quotes containing the word assumptions:

    Unlike Boswell, whose Journals record a long and unrewarded search for a self, Johnson possessed a formidable one. His life in London—he arrived twenty-five years earlier than Boswell—turned out to be a long defense of the values of Augustan humanism against the pressures of other possibilities. In contrast to Boswell, Johnson possesses an identity not because he has gone in search of one, but because of his allegiance to a set of assumptions that he regards as objectively true.
    Jeffrey Hart (b. 1930)

    What a man believes may be ascertained, not from his creed, but from the assumptions on which he habitually acts.
    George Bernard Shaw (1856–1950)

    Why did he think adding meant increase?
    To me it was dilution. Where do these
    Innate assumptions come from?
    Philip Larkin (1922–1986)
