A new methodology to analyze the functional and physical architecture of existing products for an assembly oriented product family identification Enhancement of clean-in-place procedures in powder production using ultraviolet-induced fluorescence Enhancement of clean-in-place procedures in powder pr

In today’s business environment, the trend towards more product variety and customization is unbroken. Due to this development, the need of agile and reconfigurable production systems emerged to cope with various products and product families. To design and optimize production systems as well as to choose the optimal product matches, product analysis methods are needed. Indeed, most of the known methods aim to analyze a product or one product family on the physical level. Different product families, however, may differ largely in terms of the number and nature of components. This fact impedes an efficient comparison and choice of appropriate product family combinations for the production system. A new methodology is proposed to analyze existing products in view of their functional and physical architecture. The aim is to cluster these products in new assembly oriented product families for the optimization of existing assembly lines and the creation of future reconfigurable assembly systems. Based on Datum Flow Chain, the physical structure of the products is analyzed. Functional subassemblies are identified, and a functional analysis is performed. Moreover, a hybrid functional and physical architecture graph (HyFPAG) is the output which depicts the similarity between product families by providing design support to both, production system planners and product designers. An illustrative example of a nail-clipper is used to explain the proposed methodology. An industrial case study on two product families of steering columns of thyssenkrupp Presta France is then carried out to give a first industrial evaluation of the proposed approach. Abstract In powder manufacturing facilities, clean-in-place (CIP) is a technique utilised for cleaning internal surfaces of equipment without having to dismantle them. However, the process is commonly based an open loop approach with parameter settings dependent on estimation and assumptions, leading to increased energy consumption and decreased process availability. It has previously been demonstrated that ultraviolet-induced fluorescence of proteins can be used for the detection of liquid foodstuffs in order to reduce CIP cycle times. This research investigates the suitability of an RGB vision sensor for detecting ultraviolet induced fluorescence of proteins in a range of powders (foodstuffs and detergents) under a simulated cleaning process. An image processing procedure is described that enables the evaluation of remaining fouling within a sample. The sensitivity of the system is demonstrated by comparing the coverage (area) of fouling against the volume remaining (weight). The suitability of the technique for industrial application is discussed.
