  • Method of analyzing and optimizing a multistage manufacturing process
    Patent number: 6609040
    Abstract: Method of analyzing and optimizing a multistage manufacturing process which includes a number of standard steps that are carried out identically and which are followed by tuning steps that are carried out in order to achieve predefined product properties, their type, number and exit being variable. The individual steps relate to at least one production-specific property an are recorded quantitatively in an electronic database. The property can be, for example, a proportion of the quantities, a proportion of the costs, or the effects of an individual step on a product property to be achieved. Examples of a multistage manufacturing process are the manufacture of a coating from a plurality of individual components and additives. With the aid of the information compiled in a database, individual steps can be reduced in terms of their number and their extent.
