摘要： A computer solves an item-based one-dimensional sub-optimization problem independently of the other items (305). For the item-based solution found, the computer determines whether machine interference between the items is eliminated and whether a work-in-process inventory is sufficient (309). If machine interference is not eliminated or the work-in-process inventory is not insufficient, then the computer updates a corresponding Lagrange multiplier (310, 311) and reexecutes step (305).

摘要： A computer solves an item-by-item linear partial optimization problem independently of other items (305). The computer judges if the mechanical interference between the items with reference to the obtained solution item by item is resolved and if the inventory of the goods in process is sufficient (309). If the mechanical interference is not resolved or if the inventory of the goods in process is not sufficient, the computer updates the corresponding Lagrange's multiplier (310, 311) and executes step 305 again.

摘要： In a manufacturing system that has a plurality of sheet fabrication machines, to enhance the efficiency of the system, there are provided a plurality of databases each for storing particular data relating to the machines, the types of materials to be used, the tooling of the machines, etc. of the system. When a multi-dimensional model of a component part to be produced by the system is input to the system, selective data is retrieved from the various databases so that at least one machine of the plurality of machines of, the system is selected to produce the part from a worksheet of a chosen material. Concurrently, or shortly thereafter, a NC part program for programming the selected machine to execute the necessary operations in accordance with a flat drawing generated from the multi-dimensional model to fabricate the component part is generated based on selective data retrieved from the databases. With the NC part program, the selected machine performs the operations necessary for producing the component part from the sheet stock material chosen for the component part. If there are multiple component parts to be produced in the same production run, the system would sort the different parts and arrange for the ordered fabrication of the different parts by respective selected machines equipped with corresponding appropriate NC programs to eliminate any potential bottleneck or conflicts that may arise due to the fabrication of multiple parts by multiple machines during the same production run.
