Abstract: A method, system, and software for assessing the cost tradeoffs associated with performing inspection includes determining measurement variations and product characteristic variations to define an inspection plane. The inspection plane is divided into a plurality of regions corresponding to respective different outcomes resulting from an inspection process. The probability of each outcome is determined based on a probability mass in each region of the inspection plane, wherein the probability mass is based on a joint probability density of the measurement and product characteristic variations. Costs are associated to various outcomes based on the inspection process, and overall costs of the inspection process are computed by using the associated costs and the determined probability of each outcome based on the regions of the inspection plane.

Abstract: In a system and method for saving and retrieving process capability and guidance information related to supporting product design and manufacturing activities, specific capability and guidance information related to sets of standardized product attributes are collected and stored as a plurality of records in a database. A user may then access the database through a suitable computer program interface and design a product using any combination of standardized attributes. Upon each attribute selection, the system queries the database and retrieves the process capability and guidance information associated with the received set of attributes. This information is then displayed to the user to assist in product design and manufacturing activities. Users may also group information retrieved relating to various sets of attributes and generate composite checklists including ranked listings of relevant guidance information.

Abstract: A method for providing producibility information to a user during a design process includes providing process capability models with integrated coaching information and providing a producibility evaluation worksheet having at least one input and at least one output, the input being selectable to represent a specific design. The worksheet is initialized with a relevant process capability model that is used to determine a producibility measure indicating an effect of the input on the output. The producibility measure is then displayed to the user.

Abstract: A method for evaluating performance of a production process by users includes using a system including a server and at least one device connected to the server. The method includes determining evaluation area categories, receiving information relevant to the performance of the production process within the evaluation categories, compiling the received information, comparing the received information to reference information, and displaying the results to the user via the device.

Abstract: A tolerancing method includes modeling positions and sizes of apertures in an assembly of parts. The parts are best-fit together. Aperture position in the parts is statistically varied. The best-fitting and statistical variations of the aperture positions are repeated for a statistically significant number of trials to create a statistical model. The size of fasteners for assembly through the mating apertures may be selected as determined in the statistical model.
