Claim:
A machine-readable storage medium comprising a computer program, which, when executed by a computer, causes a device to perform a demand dispatching method for managing a first fabrication with a production line having a capacity, the method comprises: receiving a first demand; providing a risk database recording risk information for a first demand, wherein the risk information comprises a first percentage of a low risk part of the first demand and a second percentage of a high risk part of the first demand, a first order rate for the row risk part, and a second order rate for the high risk part, wherein the high risk part is considered as an overestimated part of the first demand, and the first order rate and the second order rate are the possibility of the low risk part and the high risk part to become actual order, respectively; dividing the first demand into a low risk demand and a high risk demand according to the first percentage of the low risk part and the second percentage of the high risk part, wherein the low risk demand is obtained by multiplying the first demand by the first percentage, and the high risk demand is obtained by multiplying the first demand by the second percentage; determining an expected quantity of the first fabrication; and managing the capacity of the first fabrication by dispatching portions of the low risk demand and the high risk demand to the first fabrication according to the expected quantity, and the first order rate and the second order rate, thus to allocate the capacity of the first fabrication accordingly, wherein a first quantity of the low risk demand and a second quantity of the high risk demand are dispatched to the first fabrication, the first quantity is less than the amount of the low risk demand, and the second quantity is less than the amount of the high risk demand, and the amount of the first quantity multiplied by the first order rate and the second quantity multiplied by the second order rate is equal to or greater than the expected quantity.
