25. A method of IC product manufacturing, comprising the steps of:
receiving a demand plan corresponding to an IC product from a participating customer, wherein the demand plan is quantity-based, and designates a specific quantity of the IC product;
providing a capacity model having route information of the IC product, wherein the route information records a plurality of tools that used for producing the IC product, and corresponding machine time that the IC product spent on the respective tools;
transforming the quantity-based demand plan into a machine-time-based plan according to the route information in the capacity model and the specific quantity of the product, wherein the machine-time-based plan indicates specific machine times for the respective tools;
reserving capacity according to the machine-time-based plan, wherein the capacity is machine-time-based, and represented by machine times of the respective tools;
receiving a purchase order corresponding to the IC product from the participating customer before a cutoff date of the IC product;
transforming the purchase order into a machine-time-based order according to the route information in the capacity model;
accepting the machine-time-based order and decreasing the reservation capacity depending on the machine-time-based plan; and
manufacturing the IC product corresponding to the purchase order using the assessed capacity.
