Abstract:
A method for preparing a manufacturing plan, for a manufacturing factory charged with a plurality of manufacturing processes and having a plurality of manufacturing equipments, each of which is available for the plurality of manufacturing processes, for determining an assignment of the manufacturing equipments to the manufacturing processes, comprising:temporarily assigning the manufacturing equipment to the manufacturing processes to determine a supposed operation pattern for a day, allotting work load of each manufacturing process of the day among the manufacturing equipment assigned to the manufacturing process, calculating total load of each manufacturing equipment by summing the work load allotted from the manufacturing processes, calculating a capability index by dividing capacity of each manufacturing equipment of the day by the total load of each manufacturing equipment, multiplying the capability index of each manufacturing equipment by the work load allotted from each manufacturing process to the manufacturing equipment together to provide a feasible load of each manufacturing equipment for the manufacturing process, summing the feasible load of each manufacturing equipment to provide a total feasible load of the day for the manufacturing process, and comparing the total feasible load with the work load of the day for each manufacturing process to determine acceptability of the supposed operation pattern.
