Modifying operational efficiency by repositioning process apparatus
There is provided a production processing system including: a production efficiency improvement device configured to select a processing apparatus that processes workpieces in consideration of a position of each of a plurality of processing apparatuses arranged along a transfer path; and a transfer control device configured to move a transfer apparatus that transfers workpieces from a predetermined position on the transfer path to the selected processing apparatus.
Workpiece processing system for carrying out sequential execution of process of workpiece in each process chamber by setting start time of process in each process chamber based on necessary processing duration specific to each chamber and necessary conveyance duration between the chambers
A workpiece processing system and method to process a workpiece in processing chambers in order, in which even if processing duration varies at any chamber, such a variation does not affect the processing of the workpiece in other chambers. Each chamber performs processing of a workpiece in a predetermined order; a conveyor that conveys a workpiece to a next chamber; and a control device controls at least a start time of predetermined processing at each processing chamber. The control device sets: predetermined representative processing at a first chamber as a reference processing step, start time of the reference processing step as control start time, necessary processing duration specific to each chamber, necessary conveyance duration required to convey a workpiece between the chambers, and controls starting of the representative processing at each chamber while considering the control start time as origination.
System and method for providing short-term dispatching decisions for operating a number of resources involved in a number of production processes under consideration of long-term objectives
The disclosed is a system and production processes, comprising a processor to perform the steps: a) obtaining a long-term production schedule containing production operations for a set of production orders by using forecasted values for production operation durations; b) deriving dispatching recommendations for suitable order release dates, dispatching sequences and/or resource choices of all subsequent operational dispatching decisions from the obtained long-term production schedule; c) obtaining a released subset of the set of production orders having each a release date and a due date and including information of all possible dispatching sequences and logical dependencies between them to produce a requested product; d) iteratively calculating subsequent operational dispatching decisions based on operational constraints and on the derived dispatching recommendations which support a decision-making in favor of optimizing the overall production process with respect to long-term objectives; e) outputting each calculated operational dispatching decision to a production executer.
Work planner, method for planning work, and computer-readable storage medium storing a work planning program
A work planner includes a divider and an adjustor. Based on action information including a plurality of first actions indicating work units that involve one executor or a plurality of executors including a robot and that start at respective defined start timings, the divider is configured to divide one action among the plurality of first actions that involves the plurality of executors into a plurality of second actions corresponding to the respective plurality of executors. Based on dependency information indicating a relationship of dependency among the plurality of first actions including the plurality of second actions, the adjustor is configured to adjust a start timing of at least one of third actions, among the plurality of first actions, that involve an identical executor.
METHOD AND SYSTEM FOR LOT-TOOL ASSIGNMENT
A method is disclosed and includes determining whether there is any WIP information with one or more process constraints in a process constraint database that is coupled with a manufacturing execution system; determining whether there is a dispatching rule in the dispatching rule database that is coupled with a dispatching system; generating a tool-lot relationship based on at least one of the process constraints and the dispatching rule; utilizing the tool-lot relationship to assign one or more lots to one or more tools respectively.
