Computerized scheduling methods and computerized scheduling systems according to exemplary embodiments. A computerized scheduling method may be stored in a memory and executed on one or more processors. The method may include defining a main multi-machine scheduling problem as a plurality of single machine scheduling problems; independently solving the plurality of single machine scheduling problems thereby calculating a plurality of near optimal single machine scheduling problem solutions; integrating the plurality of near optimal single machine scheduling problem solutions into a main multi-machine scheduling problem solution; and outputting the main multi-machine scheduling problem solution.

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.

According to the invention, a graphical programming language conforming to the international standard is adopted to replace a dedicated robot controller programming language based on text; the efficiency of a development process and the portability of a control program are improved; based on a modular operating environment and a standardized management command, the on-line dynamic reconstruction of the industrial robot control program can be realized; and the flexibility of a robot controller is improved.

The invention provides a distributed manufacturing scheduling method for fixed-point output. The data field model is adopted to measure a task structure and an equipment distribution state, the task structure measurement reflects the influence of a subsequent process on an alternative process, and the equipment distribution state measurement reflects the local influence of equipment in an equipment network; By adopting a reverse scheduling method, starting from termination equipment and termination working procedures, equipment is reversely distributed for the working procedures, so that fixed-point output constraint of the task is guaranteed; Quantitative measurement of the established alternative processes and alternative devices can provide a basis for task scheduling, the scheduling process is simplified, and optimization of two aspects of tasks and device structures is considered.
