the. property. of. ions. has. attractive. and. repulsive. forces.. Otherwise,. the.
molecular.property.is.related.to.the.size.of.any.substance..The.performance.
of.NT,.therefore,.could.be.expressed.as.the.manipulation.of.material.charges.
and. sizes. (nanosize). of. molecules.. The. properties. of. NT. are. usually. inves-
tigated.in.the.general.industrial.ield,.with.the.academic.approach.and.the.
marketing..Basically,.SD.can.be.expressed.in.terms.of.feedback.and.accumu-
lation.in.the.event.low,.which.is.often.used.in.the.assessment.of.new.tech-
nology. ields. like. NT,. because. progress. in. technology. is. characterized. by.
nonlinear. feedback. and. asset-added. accumulation.. There. are. comparisons.
between.feedback.and.accumulation.for.SD.in.TableĀ 9.1..These.characteristics.
are. very. important. in. dynamic. assessment,. especially. when. attempting. to.
quantify.success..Using.the.SD.method,.simulations.are.performed.for.both.
analytic.estimations.and.quantiication..SD.is.used.to.investigate.particular.
problems.taking.into.account.the.technological.implications.of.a.variety.of.
factors..Furthermore,.SD.can.assist.in.dynamic.decision.making.in.complex.
matters..The.Vensim.package.used.for.simulation.was.developed.by.Ventana.
Systems,.Inc.
