METHOD FOR MANUFACTURING AND TESTING THE FUNCTIONALITY IN MANUFACTURING
A method is proposed for manufacturing and testing of complex products, in particular motor vehicles in series production, wherein all the data for the individual manufacturing stations in the manufacturing line is stored in a central computer. In this case, different models are manufactured on the manufacturing line, such that the correspondingly configured data is provided at each manufacturing and test station for this model, after identification of the model. A technical test is carried out in conjunction with the manufacturing installation by monitoring the vehicle functions or else the equipment for their function. An attributive test is carried out by the worker at the manufacturing stations, with all the recorded test data being supplied to the central computer for central evaluation, and with the data being stored on the basis of individual categories in the central computer, such that it is possible to evaluate the manufacturing process with respect to the individual manufacturing steps.
1 . A method for manufacturing and testing of complex products, including motor vehicles in series production, which comprises the steps of:
storing all data for individual manufacturing stations in a manufacturing line in a central computer;
manufacturing different models on the manufacturing line and correspondingly configured data is read at each manufacturing and test station after identification of a model;
testing the manufacturing via a technical test in conjunction with a manufacturing installation such that a unit under test as well as equipment are monitored for function;
carrying out an attributive test via a worker at test and manufacturing stations; and
supplying all recorded test data to the central computer for central evaluation, and the recorded test data being stored on a basis of individual categories in the central computer, such that it is possible to evaluate a manufacturing process with respect to individual manufacturing steps and vehicle modules.
2 . The method according to claim 1 , wherein the attributive test is assisted by at least one of a text display and an image display of a component to be assessed, wherein fault inputs are entered by an action on a test and manufacturing station.
3 . The method according to claim 1 , which further comprises recording fault symptoms and fault causes in a comprehensive form in the central computer and are matched to different function units, such that faults which have already been caused at a previous manufacturing station are rectified by appropriate information at this or at a later test and manufacturing station.
4 . The method according to claim 3 , wherein the fault causes can be directly associated with the manufacturing station and the vehicle modules.
5 . The method according to claim 4 , which further comprises weighting the faults into different categories and, depending on a category of the fault, either an additional test person is automatically informed that a vehicle must be removed from the manufacturing line in order to rectify the fault, or that a time for reworking is allocated.
6 . The method according to claim 3 , wherein, in a case of vehicles in which the faults have not all been rectified, the vehicle is not released for delivery.
7 . The method according to claim 1 , which further comprises producing an early parts order as a result of a test for incorrect or faulty parts.
8 . The method according to claim 1 , wherein all predetermined technical and attributive test and completion steps must be acknowledged as having been carried out without faults and completely before a vehicle is released.
