Normal capacity

Normal capacity is the amount of production volume that can be reasonably expected over the long term. Normal capacity takes into account the downtime associated with periodic maintenance activities, crewing problems, and so forth. When budgeting for the amount of production that can be attained, normal capacity should be used, rather than the theoretical capacity level, since the probability of attaining normal capacity is quite high. The normal capacity level can decline over time as production equipment ages, since the equipment requires more maintenance effort.
