示例1: getBandValue
private BigDecimal getBandValue(SRVMBand band, int quantity) {
// The min{2,n} or min{4,n} part of the value function
int firstSummand = quantity > synergyThreshold.get(band.getName()) ? synergyThreshold.get(band.getName()) : quantity;
// The min{3/4, (n-1)/n} * syn_i(B)} or equivalent for other bands part
BigDecimal minFraction = new BigDecimal(firstSummand - 1).divide(new BigDecimal(firstSummand), CALCSCALE, RoundingMode.CEILING);
BigDecimal synergyFactor = intrabandSynergyFactors.get(band.getName());
BigDecimal secondSummand = minFraction.multiply(synergyFactor);
// The marginal decreasing third summand (max{0, ln{n-1)})
int toLog = quantity - (synergyThreshold.get(band.getName()) - 1);
BigDecimal thirdSummand;
if (toLog <= 0) {
thirdSummand = BigDecimal.ZERO;
} else {
double lnApproximation = Math.log(toLog);
BigDecimal ln = new BigDecimal(lnApproximation, new MathContext(CALCSCALE, RoundingMode.CEILING));
if (ln.compareTo(BigDecimal.ZERO) >= 0) {
thirdSummand = ln;
} else {
thirdSummand = BigDecimal.ZERO;
}
}
// Calculates product
BigDecimal firstFactor = new BigDecimal(firstSummand).add(secondSummand).add(thirdSummand);
BigDecimal baseValue = baseValues.get(band.getName());
// No need to take random influence and relative bidder strength into account. Is already included in baseValue;
return firstFactor.multiply(baseValue);
