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);
