A method and system for efficient allocation of limited manufacturing resources over time to meet customer demand. At the enterprise planning level this typically requires determination of a feasible production schedule for an extended supply chain. The method and system utilizes a new and unique type of systematic decomposition based on both product and process considerations. This approach simultaneously reduces the model size (and therefore computation time) and increases modeling flexibility from strictly linear programming based decision making to include more general nonlinear programming characteristics.

Disclosed is a pull-type vehicle assembly line control system and method in which a production plan for a final assembly process, or a trim process, is established first, and, using this as a basis, a production plan for a paint process then that for a vehicle body assembly process are set up. Further, in the present invention, information on the progress for the three main assembly processes--the vehicle body assembly process, paint process, and trim process--is mutually exchanged such that a dynamic re-specification assembly process is utilized in which operational sequences for each of the process are continuously readjusted to adapt to the overall assembly process.

A method and system for resource rationing which employs decision rules for the optimal allocation of supply and capacity over time that satisfy two key requirements (a) being consistent with accepted operational objectives (e.g. low inventory, short lead times, prioritized allocation of supply and capacity) and (b) allowing for the timely computation of a feasible production schedule. The method and system is generally characterized in that it is able to divide each of the priority ranked scheduled releases (Material Requirements Planning (MRP)) into "N" separate and smaller sized scheduled releases where the priority of each of the "N" releases may be equal to the priority of the original release. The "N" separate and smaller sized scheduled releases are sorted according to priority and then used to determine an optimal supply schedule for allocating resources including component supply and assembly capacity.

The present invention is to formulate a production plan 5 by means of an event-based simulator 4 simulating movement of products within a factory through use of a production process model 2 and a production rule 3. There are provided a time-interval-based simulator 6 for computing the statuses of production processes at given time intervals, and a rule generator 7 for automatically deriving the production rule 3 through use of the time-interval-based simulator 6. As a result of a production plan being repeatedly formulated at high speed through use of the time-interval-based simulator 6, the rule generator 7 can automatically, efficiently formulate the production rule 3 by application of machine learning based on a consecutive optimization method. An event-based simulator 4 devises a high-quality production plan 5 using the generated production rule 3.

A solution (400) for scheduling execution of jobs is proposed. The submission of the jobs is generally controlled according to a production plan (406), which specifies a required finish time of critical jobs. In the proposed solution, a current progress of each critical job is monitored (427-430)—such as comparing a (measured) number of processor cycles dedicated to the critical job with an estimated total number thereof (required to complete the critical job, as inferred from previous executions thereof). At the same time, an expected progress of each critical job is estimated (433)—such as by the ratio between a time elapsed from an actual start time of the critical job and an allowable duration thereof (from the actual start time to the required finish time). The current progress of each critical job is then compared with its expected progress, so as to identify (436) the critical jobs that are late in their execution. Additional execution resources can then be assigned to each late critical job only when it is necessary to bring back the critical job on schedule.

An improved process for forecasting product demand to be used within inventory management and/or production planning systems. This improved process overcomes the limitations of the prior art by providing an optimal combination of automated statistical data processing and human intelligence, in one interactive system. The new method provides an efficient means for an operator to incorporate much information, known to the operator, that would otherwise be missed by the systems of the prior art. It allows the operator to analyze information very quickly by viewing graphs drawn on a graphical user interface and to make changes very quickly using that same graphical user interface. The method relies on the use of edit markings/symbols drawn on the display portion of the graphical user interface. These edit markings/symbols are used to make changes to the parameters forming the basis for a product demand forecast. The markings/symbols are recognized by the forecast software algorithm and a new forecast is generated based on the revised parameters.
