Increasing production of automobiles has resulted in traffic congestion which is expected to drive the rolling stock market"
The rolling stock market is dominated by CSR Corporation (China), Bombardier Corporation (Canada), Alstom (France), Siemens AG (Germany) and GE (U.
Mathematical modeling of rolling stock breakdowns number
The average age of passenger rolling stock (one type of rolling stock), using the weighted average cost formula.
Rolling stock fleet, in any case, is updated from time to time.
The average age is comparable to the manufacturer's specified age, but is not advisable to draw conclusions from the average age, because it is the rolling stock fleet aver age age, not average age of single rolling stock.
n]--number of rolling stock that expected to acquire per year; [A.
where: [DELTA]g - Number of faults (per wagon per year) decreasing, when the average age of rolling stock fleet decreases by one year (in this case, [DELTA]g = 0.
When planning to buy some new rolling stock (3-6 wagons electric or diesel trains) while using this model, the number of faults can be predicted up to five years.
Rolling stock with engines (diesel and electric trains) deteriorates over time, more and more intensely, especially for the aging.
