The market demands have pushed the industries to create products to be more innovative and with less time to launch. This situation pressures the entire product life cycle, from its design and manufacturing to the delivery to the market, requiring greater speed and precision in each of these phases. The first stage of the cycle affected by this trend is the development of new products, an interactive, complex engineering and decision-making process. In this sense, it is necessary to know the main agents and actors involved in this process of developing new products and how they interact with each other so that, with this understanding, it is possible to determine the main uncertainties to be mitigated within the earlier stages and avoid potential risk for the subsequent phases of the PDP. By using the PROMETHEE (Preference Ranking Organization Method for Enrichment Evaluation) and GAIA (Geometrical Analysis for Interactive Aid) methods, this paper proposes a comparative model selecting the main components of the product development process, indicating how the interaction between them may minimize the uncertainties in the earlier stages of the PDP.

Decision Making Tool

Product cost estimation (PCE) still draws the attention of researchers and practitioners, even though it has been extensively discussed in the literature for more than 20 years. This is due to its central impact on the company's performance. Nowadays, the adoption of cost estimation methods seems to be limited, despite the multitude of examples and applications available. A possible reason is the multitude of approaches and techniques proposed in the literature, which, instead of representing a guide for enabling possible implementations, actually create confusion and ambiguity on their appropriateness for a particular application. Hence, this paper aims to provide a systematic review of the recent literature in the field of PCE, and intensively investigates the aspects that can enable a more conscious decision on the type of technique to be adopted. This results in the identification of five different perspectives, which can be taken simultaneously into account. By combining the different viewpoints, a new multilayer framework is derived, with a specific focus on the whole product life cycle. The proposed framework can be used as a decision-making tool by both researchers and practitioners. In fact, the former group can benefit from the new structure, as a way to identify new areas of possible research opportunities. The latter group is provided an operative guide for the application in industrial contexts.

Maintenance And Repair

New customer demands and increased legislation drive business-oriented companies into new business models focusing on the entire life cycle of the product. This forces the manufacturing companies into service-oriented solutions as a compliment to the original business areas. Takata [1] postulates that “the goal is no longer to produce products in an efficient way, but rather to provide the functions needed by society while minimizing material and energy consumption”. This new situation affects the product requirements as well as product development process (PD). When focusing on the entire product life cycle, product aspects such as maintenance and repair will receive more attention since the companies will be responsible for them. In the product development process of today, especially in the automotive industry, maintenance and repair aspects (repair and maintenance methods and manuals, for example) are currently taken care of when the product is more or less fully developed. Maintenance and repair requirements are difficult to quantify in terms of core product properties (for vehicles, cost, CO2 emissions, weight, and so on). This leads to difficulties in equally considering maintenance and repair requirements while balancing vast amounts of product requirements. This paper focuses on a comparison and discussion of existing design guidelines affecting the structure and organization of parts in an assembled consumer product, such as Design for Assembly (DFA), Design for Maintenance (DFMa), Design for Service (DFS) and Design for Disassembly (DFD) methods. A tool for evaluation and analyzing product architecture as well as assemblability and maintainability is proposed.

Environmental consciousness has gained increasing interest in recent years, and product life cycle design that aims to maximize total value while minimizing environmental load and costs should be implemented. To achieve that, the processes of idea generation and decision-making for eco-business strategies, as well as the design of a target product and its life cycle options, should be systematically supported. This paper proposes a strategic decision-making method for eco-business planning so that a designer can easily find a set of eco-business ideas that effectively improve environmental and economic performance simultaneously. A decision-making procedure based on this method is also illustrated with a simplified example of a laptop computer business.

Material Information

Materials play a central role in product manufacturing, contributing to each phase of product development in the form of either a component or process material. As the product revolves around materials, so does much of the product information. Material information plays a significant role in the decision making process at any stage of the product life cycle, especially with respect to the sustainability of a product. Material information in the manufacturing stages of a product’s life cycle will relate to the processes used in manufacturing and assembling individual components. The material properties may determine what processes can be used and how these processes should be controlled. To support sustainable manufacturing, the impacts of material choice should be considered during design, when resources are being committed. When comparing material alternatives at design time, it is not as simple as saying one material is “more sustainable” than another. Many different factors determine the sustainability of a product, and each of these factors may be influenced by multiple material properties represented through various information requirements. In order to develop a material information model that can satisfy these information requirements, we need to carefully study the requirements from an information modeling perspective. In this paper, we use activity models to describe design and manufacturing scenarios that rely on the availability of proper material information for sustainability decision making. We will use these models to first define specific scenarios and then to identify the types of material information that is typically required in these scenarios, and collect and categorize key concepts. Based on this study, we will make recommendations that will aid the development of a useful material information model for sustainable decision making.

Life Cycle Cost (LCC) is important information that is useful for decision making affecting complex engineering systems with extended life. Uncertainty in the estimation of LCC, especially in the early concept and definition stage, has great influence on the robustness of such decisions. Conventionally, Verification and Validation (V&V) of cost estimates is not performed, either due to economic or practical constraints. This paper presents a framework for considering uncertainties in quantitative life cycle cost estimation, focusing on the aspects that are important for understanding the discrepancies between the estimated and actual costs. Built on experience in verification and validation in engineering, the framework will be used to guide further research in this topic, where emphasis on suitable theories and models of different types of uncertainties in the estimation as well as strategies to deal with them effectively to improve decision making involving LCC will be discussed.

This paper examines the relationship between organization size, product life-cycle stage, market position, balanced scorecard (BSC) usage and organizational performance. Using financial and nonfinancial measures, the BSC appraises four dimensions of performance: customers, financial (or shareholders), learning and growth, and internal aspects. Based on a survey of 66 Australian manufacturing companies, the paper suggests that larger firms make more use of a BSC. In addition, firms that have a higher proportion of new products have a greater tendency to make use of measures related to new products. A firm's market position has not been found to be associated significantly with greater BSC usage. The paper also suggests that greater BSC usage is associated with improved performance, but this relationship does not depend significantly on organization size, product life cycle, or market position.
