Design And Manufacture

The initial investigations are presented into three equipment design and manufacture companies, and their issues relating to information loss and inaccuracies, and present the employment of an extended product model framework to assist the engineers in overcoming the issues identified. Three key scientific issues in this field are addressed. They are the customer driven goals and practices, design change capture and product models, and the methodology employed to answer the problem stated. The information generated during the service engineer’s visit and the redesign process is encapsulated within a new ExProMod, so that it could potentially be revisited and retrieved throughout the whole product life. A case study has shown that the proposed ExProMod is able to record the information generated in a constraint-based design/redesign so that it has the capability to assist the designers to assimilate and digest constraint-based design, assist the designers to assimilate and digest constraint-based design, offer information management benefits for the machine redesign in the industry, and Presents a tool to capture redesign changes and their respective rationale. In addition, the directions for future research are also prospected.

Data Requirements

Abstract Product models come from the analysis of the data requirements to support the design and manufacture of products. These models are implemented in databases aimed at providing information to software applications that assist the concurrent design of products. This paper presents the requirements of a data model driven software system to aid the design of injection moulds and analyses two product models which were developed in different contexts but capable of representing injection moulded parts and moulds. A case study is used to show the application of each one of the models selected. Finally, some conclusions of the analysis are drawn in order to set the foundation of a new model.

Model Support

Product models come from the analysis of data requirements to support product design and manufacture. These models are implemented in databases aimed at providing information to software applications that assist the concurrent design of products. This paper presents the specifications of data models to assist the concurrent design of injection plastic parts and their moulds. The product models are original since they capture part and mould life cycle aspects using the same data structure. The models also link product functional information to the design process and consider the capacities of an injection machine. The paper introduces the underlined structure of the above mentioned data models and uses a case study to show their capabilities. Finally, some conclusions are presented.

The Impact

Conceptual design for complex products like aircraft and power plants requires a considerable effort since the product models become very large if they are to cover all important aspects for different stakeholders. To cope with this overall effort, designers have to rely on legacy designs and reuse, and improve the product concepts incrementally between product generations. This paper describes a generalized inheritance mechanism we call generic object inheritance that enables quick reuse and modification of conceptual product models at any level in their hierarchical break down structures. By facilitating reuse of conceptual models of previously well studied products, more time can be spent on developing the parts that contain the edge of a new product generation. This enables keeping the modified concepts in context of a complete analyzable product model where the impact of changes can be studied without having to maintain multiple copies of the same object structures. The paper describes how generic object inheritance is used for developing the next version of a conceptual product model of a small business jet, while reusing the essential parts of the previous version with minor modifications to design parameters and substructures. The design and core mechanisms of generic object inheritance are briefly described, and illustrated with examples from the case study.

Information Management Systems

It is agreed that good communication systems between organisations increase customer satisfaction and relationship behaviour. However, less is known about the details of how information is used to manage relationships. Theories that have been found have either been tested on non-perishable goods or on small case studies. In earlier stages of the research, a dynamic model of inter-organisational information management systems (IOIMS) and relationships was developed based on a netchain case study. This paper presents an evaluation of this model based on a survey of Australian food processors and a green life industry case study. Both studies found that the environment (power, dependency and market uncertainty) had a significant influence on (attitudinal) commitment to develop long-term customer/supplier relationships. In addition, the nature of the IOIMS was associated with perceived current outcomes (satisfaction with performance, perceived responsiveness and strength of relationship trust). However, commitment to develop long-term customer supplier relationships was not significantly associated with the IOIMS. Conclusions were more doubtful about the association between the business environment and the IOIMS and perceived current outcomes. Suggestions for future research are made.

Carbon Footprint Assessment

The Life Cycle Assessment (LCA) system, which can be used as a decision support tool for managing environmental sustainability, includes carbon footprint assessment as one of the available methodologies. In this study, a carbon footprint assessment was used to investigate seawater production systems of a desalination plant in Senok, Kelantan, Malaysia. Three stages of the desalination plant processing system were investigated and the inventory database was developed using the relevant model framework. Subsequently, measurements and interpretations were performed on several key indicators such as greenhouse gases, energy efficiency, acidic gases, smog, and toxic gases. Overall, the results of the study indicate that the Reverse Osmosis (RO) technology that is used in the desalination plant in the study area is one of the best options to meet the demands of the environmental sustainability agenda (SDGs). This is due to the lower carbon dioxide (CO2) emission, of about 3.5 × 10−2 kg of CO2 eq per m3/year, that was recorded for the entire operation of the system. However, several factors that influence important errors in carbon footprint decisions, such as the lack of EIA reporting data and the literature on carbon footprint in the Malaysian scenario, in addition to direct and indirect carbon input calculations, need to be identified in more detail in future research.

AbstractWith the proliferation of tobacco and nicotine products, there might be a need for more complex models than current two-product models. We have developed a three-product model able to represent interactions between 3 products in the marketplace. We also investigate if using several implementations of two-product models could provide sufficient information to assess 3 coexisting products. Italy is used as case-study with THPs and e-cigarettes as the products under investigation. We use transitions rates estimated for THPs in Japan and e-cigarettes in the USA to project what could happen if the Italian population were to behave as the Japanese for THP or USA for e-cigarettes. Results suggest that three-product models may be hindered by data availability while two product models could miss potential synergies between products. Both, THP and E-Cigarette scenarios, led to reduction in life-years lost although the Japanese THP scenario reductions were 3 times larger than the USA e-cigarette projections.

The paper presents a theoretical approach and a case study upon the use of an advanced CAD solution integrated with another engineering design software solution embedding DFMA concepts, particularly applied within the product and manufacturing process design for technological devices. The main objective of implementing CAD and DfX/DFMA integrated solutions is to guide designers into the product development phase so that a better design can be achieved in a shorter time and with lower costs. The case study analyzes an assembly model developed for an indexing mounting table dedicated for the automated assembling of an industrial electrical plug inlet. The assembly product model has been developed using 3D parametric modeling specific tools, further on it has been subjected to analysis based on DFMA principles and after that its components have been redesigned to respond to the analysis results. Some of the case study results and their interpretation are discussed in the paper content and finally some overall conclusions are included along with some intended future research directions.

Virtual Prototypes

Abstract Most virtual prototypes used within the domain of mechanical engineering are well defined geometric representations loosely linked to analysis packages. By taking a holistic, top-down view of the product introduction process this paper argues that virtual prototypes should be based upon product models that allow for the representation of more than just geometric information. A methodology based upon the reference model for open distributed processing is presented that simplifies the task of deciding what information should be supported. The paper argues that virtual prototypes should use product models that integrate the representation of the geometry, function and behaviour of a product. A case study is presented to show how experimental virtual prototyping software, based on such a product model, can aid the product introduction process.
