摘要:
A method for automatically controlling a production process for the mass production of order specific products with a first and a second partial process and an exit buffer (500.3) which comprises a fixed maximum number of spaces for production objects (20.2, 20.3,). A sequence (60) for the order of products, which are produced in the production process, is produced. In the first partial process, objects are produced according to the order sequence (70). A selection process occurs, wherein a produced object from the produced object sequence and an application from the application sequence, corresponding to each other, are selected. If the first application of the application sequence does not match a production object in the exit buffer or corresponds to a first produced object from the sequence of produced objects and if sufficient free space is available in the exit buffer, the first application and the produced object matching the sequence of produced objects are selected. All production objects from the sequence of produced objects (70) are adjusted in the exit buffer (500.3) before the selected production object. Preferably, the number of available spaces is determined by the simulations.

A build-to-order production process is determined in consideration of magnitude of demand. A lead time calculating section (122) calculates process-specific lead time proportional to the time at which the number of items required to produce the amount of demand for products which are periodically ordered is processed for each process of manufacturing a product and selects a process in the range in which the sum value after the calculated process-specific lead time is added to the travel time between the processes does not exceed the lead time permissible by the client as a build-to-order selection process.
摘要:
A method and a system control just in time item production via kanban cards. The items are transformed according to a flow shop containing a raw material buffer followed by a sequence of production pairs containing one workstation and an assigned buffer. A local buffer threshold parameter is provided and denotes the desired safety stock of the items of the specific type in the buffer. A global demand threshold parameter is provided and denotes the quantity of items of the specific item type required along the downstream process to satisfy the estimated demand. Whenever a kanban card is associated to an item of a specific type switches status, it is assigned one of four priority levels indicating the priority level of the production request. At each production pair, an item is produced of a type whose priority level is the highest according to a given priority model.

A system for manufacturing blinds comprises a processor unit, at least one manufacturing facility for carrying out a manufacturing step and a communication device for exchanging data between the processor unit and said at least one manufacturing facility. To arrange for efficient and economical manufacturing, whereby manufacturing time and scrap are relatively low, the processor unit is adapted to generate data for controlling the system taking into account an order portfolio and at least one parameter from said at least one manufacturing facility.
摘要:
The present invention relates to a manufacturing system which accepts a custom order of product from a customer and custom manufactures a product without sacrificing manufacturing efficiency. The manufacturing system includes the featuring steps of inputting the required specification of a product, creating the product design based on the design information of the product transmitted from a designing department, status data from the production department, and the input required specification, showing the created product design to the customer, selectively indicating a product to be purchased, transmitting the specification of the selected product to the production department, and producing a product based on the selected product specification.
