An object-oriented reference model of the fuzzy front end of the new product introduction process

The global pressures of the modern market are placing an ever-increasing emphasis on the rapid development and introduction of new products. Central to this aim is the implementation of an effective business process for managing and controlling product innovation. Research has shown that the front end stages of the so-called new product introduction (NPI) process are weakest in a high proportion of companies and direct support is needed in this area. This paper describes how an object-oriented methodology has been applied to develop a reference model and architecture to facilitate the re-engineering and implementation of a high quality business process and help remove the fuzziness of the critical early stages of NPI. The results from the application and testing of this tool within a wide range of different companies are summarised and used to help derive conclusions regarding the validity of the research.

Overlap at the back and front end in slab ingot rolling

Overlap formed at the back and front end in slab ingot rolling is studied theoretically and experimentally. The phenomena are analysed by means of plane strain upper bound solutions for a rigid perfectly plastic material. According to theory the crop loss volume at the front end should be larger than that at the back end. It is concluded that large roll diameters should be used in order to minimize the crop loss. For heavy reductions and large roll diameters the dependence of reduction on the crop loss at the back end is small. The dependence of roll radius is found to be more pronounced for the front than for the back end especially when heavy reductions and small roll radii are concerned.Theory is in good agreement with experiments carried out with plasticine as the model material.     

A hybrid method for product low-end disruptive innovation

Product innovation is often a process for improving existing products. Low-end disruptive innovation (LDI) enables a product to meet the most price-sensitive customers in the low-end market. The existing LDI methods are mainly based on unnecessary characteristics of disruptive innovations. Thus, they cannot easily identify and respond to the LDI design needs. This study proposes a hybrid method for the product LDI in two levels of the product design based on the summarized definition and essential characteristics of LDI. Feasible areas of the product LDI are determined using a hybrid relational function model to identify the maturity of dominant technologies. The technologies are identified through the technical search and evaluation of the feasible area for innovation to form an initial LDI scheme. Then, the product function is optimized using the trimming concept of theory of inventive problem solving based on the characteristics of LDI. The final LDI scheme is formed and evaluated based on the essential characteristics of the product LDI. The feasibility of the proposed method is verified in the design of a new dropping pill machine.
