Abstract Design for the life cycle practices enable the improvement of a product’s recycling, disassembly, and service characteristics, to name a few. In this paper, an approach to virtual prototyping is presented that supports product Design For Assembly, Disassembly, and Service (DFADS). The VP-DFADS system enables a designer to construct a product model, to interactively simulate an assembly, disassembly, or service process for that product, and to formulate and solve a simultaneous product/process design problem. Specific research objectives underlying this project include a reduction in VP model construction times, an improvement in information with which designers make DFADS decisions, and the development of a design synthesis method for DFADS. Although automated reasoning and synthesis technologies are outlined, the emphasis in this paper is on the integration of these technologies into the VP-DFADS system and on the usage of the system in supporting DFADS decisions. An application of the VP-DFADS system to automotive center console design illustrates the potential usefulness of the VP-DFADS approach.

Virtual Prototypes

Abstract With the introduction of virtual prototyping into the product development process, simultaneous product/process design is enabled. The research reported in this paper illustrates an integration of product and disassembly process design via virtual prototyping. In this context, a virtual prototype is an information model consisting of a product model and one or more process models. Virtual prototype generation is a hybrid process consisting of both automated and interactive tasks. Simultaneous product/process design is accomplished by formulating the integrated product/process design problem as a multiobjective optimization problem in which product/process requirements are evaluated via virtual prototyping. Solution of the integrated product/process design problems is achieved through the application of the MORPS algorithm. Application of the use of virtual prototypes is presented in the simultaneous product/process design of an automotive center console.

Abstract The difficulties in identifying the precise defect location and real leakage path is increasing as the integrated circuit design and process have become more and more complicated in nano scale technology node. Most of the defects causing chip leakage are detectable with only one of the FA (Failure Analysis) tools such as LCD (Liquid Crystal Detection) or PEM (Photon Emission Microscope). However, due to marginality of process-design interaction some defects are often not detectable with only one FA tool [1][2]. This paper present an example of an abnormal power consumption process-design interaction related defect which could only be detected with more advanced FA tools.

Steam Drying

Optimization of process steam requirement in order to maximize sugar recovery and export power along with manpower optimization is a must for sugar factories to survive under difficult conditions and to earn additional revenues. The process steam demand of greenfield and revamped plants has been reduced to levels of 32–38% from originally more than 50% steam on cane in the case of the brownfield plants. In addition, significant improvement in the power requirement of the plants has been achieved. Bagasse drying offers a good potential to improve the power export. Different available concepts are compared with a focus on bagasse steam drying and low temperature bagasse drying. In order to set up an optimized highly efficient plant or to optimize an existing plant to achieve competitive benchmarks, good process design and the right equipment selection are very important. Experience has been gained with multiple stage or double effect crystallization in the beet sugar industry offering further steam optimization potential. Vapour recompression is also an option to substitute live steam by electrical power. This even provides options to reduce the steam demand from the power plant for the sugar process down to zero. Key aspects concerning the process design and equipment selection are described.
