Lifecycle Design

Engineering products go through 4 stages of lifecycle; design, production, use, and disposal. Engineers have developed tools for avoiding design flaws that cause troubles in the later stages. Accidents and malfunctions, however, still happen and some are even catastrophic. Once in the market, products require service. Whether scheduled, or unexpected, service is mostly carried out by subsidiaries of the manufacturer or sometimes unrelated specialists. When product troubles occur, service companies tend to seek solutions within their own organization without going back to the design stage. This approach may prove less costly, however, quick fixes may lead to disasters. Industries currently lack effective ways of feeding service information back to design. We analyzed some real accidents that took place in Japan where hard work in the use stage triggered the events. Information from the use stage to design will prevent accidents and also improve design to closely model reality.

Lifecycle Design

The Predictive Product Lifecycle Design (PPLD) model that is proposed in this paper enables a company to optimize its product lifecycle design strategy by considering pre-life and end-of-life at the initial design stage. By combining lifecycle design and predictive trend mining technique, the PPLD model can reflect both new and remanufactured product market demands, capture hidden and upcoming trends, and finally provide an optimal lifecycle design strategy in order to maximize profit over the span of the whole lifecycle. The outcomes are lifecycle design strategies such as product design features, the need for buy-backs at the end of its life, and the quantity of products remanufacturing. The developed model is illustrated with an example of a cell phone lifecycle design. The result clearly shows the benefit of the model when compared to a traditional Pre-life design model. The benefit would be increased profitability, while saving more natural resources and reducing wastes for manufacturers own purposes.

Sustainable product development (SPD) requires that product design achieve minimal or zero environmental impact, while satisfying other design criteria such as functionality, quality, desirable features, and acceptable cost and time to market. Therefore, environmental evaluations must be incorporated into the design stage. This research is aimed at the development of a new approach to lifecycle design and evaluation. This paper proposes a framework to optimize functional, environmental, and economic (FEE) performance towards sustainable design. Based on the three dimensions of FEE, a systematic lifecycle design process model is proposed, which consists of: the three FEE requirements; two design objects (physical structure and lifecycle structure); and, the FEE evaluation streams of LCQ (functional lifecycle quality), LCA (environmental lifecycle assessment) and LCC (economic lifecycle costing). A new concept, called process-based analysis (PBA) is defined, and used as the base for FEE evaluations.

Actual Use

One of the most common procedures in service transport is to adjust the service location information of the passengers or the bus stops. Service companies assign a staff to update service information. These staff prepare lists of passengers and give them to service drivers. In this study, a model is proposed to facilitate the process of updating the service. With the smartphone application, a platform has been prepared in which passengers can automatically update their service information by selecting one of the three closest stops offered to them before the service hour. After development and implementation, its user acceptance is tested and validated via the unified theory of acceptance and use of technology (UTAUT) model and structural equation modeling. The main purpose of this study is to determine the acceptance and use of the mobile passenger application by the passengers. In this context, the moderator effect of the frequency of mobile use of passengers, education levels, genders, and ages on the performance expectancy, effort expectancy, facilitating condition, behavioral intention, and use behavior of passenger mobile applications was examined. As a result of the research, it was found out that the frequency of mobile usage has a moderator effect on both the effect of facilitation conditions on the actual use and the effect of behavioral intention on actual use. And also, it appears that the education level has a moderator effect on the effect of facilitating conditions on the actual use, and gender has a moderator effect on the effect of behavioral intention on the actual use. The proposed decision support system reduces the workload of service companies and facilitates the process, which is normally long and painful. Thus, customer satisfaction also increases. Hence, position and stop information between the service firm, passengers, and the drivers is easily and instantly shared.

The purpose of the work consists in the presentation to the scientific community a special methodology for tribo-system designing, where a design process interacts with the analysis of possible behavior of a friction angle while operating specified technical conditions taking into account an environment impact that is taking into account a forecasting of tribo-system behavior under specified conditions. For that the best possibility is the creation of the computer model of a friction unit with the estimate of its time behavior during the impact of outer parameters upon it and the impact of inner factors, for this purpose a design-engineer must have competences in different fields of science and technology. Besides, a designer must develop procedures for replacement, restoration and repair to support an operating status of the equipment under development for the whole life required. A basic method of friction process investigations is a computer modeling of friction unit behavior. The result and investigation novelty is the development of a special methodology for designing technical systems taking into account the simulation of their evolution ensuring product quality at the designing stage. In such a way there are shown principles for machinery quality assurance during designing engineering systems.

With the increasingly intense competition in the market, more attention has been paid to customer’s perceptual requirements. Combining human sensibility and technology, Kansei Engineering plays a crucial role for industrial designers in making decisions at an earlier design stage in product development. However, sometimes it is challenging to define the customer requirements during the market research phase, especially for the perceptual requirements. Given this problem, this paper develops a process for establishing perceptual indexes based on the axiomatic design approach to improve design efficiency. To achieve this, an initial perceptual index is first built based on data previously collected from designers or design agencies. Then, the theory of axiomatic design is used to classify the schemes. The final perceptual index is filtered and built according to the frequency of occurrence.

Abstract This paper shortly presents the issue of utilization of ships after their withdrawal from service. Information on number of floating units liquidated in previous years was presented. Hazards to the environment, health and life of workers employed in the Far East ship scrapping yards operating on the beaches, were indicated. Then, the most important rules which have to make the ship recycling process safe were referred to. This author proposed to supplement the rules by environmental hazard indices which would be determined already in ship design stage. According to the concept the indices should take into account amount of dangerous substances used for building the ship as well as degree of their harmfulness (weighing factors). Two approaches to the issue of determining the weighing factors were proposed: deterministic and fuzzy.

This article discusses a method for predicting society’s requirements for the braking performance of cars, which at the preliminary design stage allows them to maintain their high technical level for the period of design, production and product life. Also in the work, an indicator is proposed to assess the level of society’s requirements for the braking properties of cars - the coefficient of braking dynamism made it possible to determine for vehicles of category M1 that, with today's requirements of the company, its value is close to unity. This means that with further tightening of the requirements of regulatory documents, the magnitude of their change will be commensurate with the measurement error during braking tests.

Potential Improvement

In today’s world it is more important than ever to quickly and accurately satisfy customer needs when launching a new product. It is equally important to design products that adequately accomplish their desired functions with a minimum amount of failures. When failure analysis and prevention are coupled with a product design from its conception, shorter design times and fewer redesigns are necessary to arrive at a final product design. In this article, we explore the potential of a novel design methodology to guide designers toward new designs or redesigns that avoid failures. The Elemental Function-Failure Design Method (EFDM) is based on functional similarity of the product being designed to failed products within a knowledge base. The idea of using component functionality to explore the failure space in design was first introduced as a function-failure analysis approach by Tumer and Stone (2003). The overall approach offers potential improvement over current failure analysis methods (FMEA, etc.), because it can be implemented hand in hand with other conceptual design steps and carried throughout a product’s design cycle. In this paper, this idea is formalized into a systematic methodology that is specifically tailored for use at the conceptual design stage before any physical design choices have been made, hence moving failure analysis earlier in the design cycle. In the following, formalized guidelines for using the EFDM will be outlined for use in new designs and for redesign in existing products. A function-failure knowledge base, derived from actual failure occurrences for Bell 206 rotorcraft will be introduced and used to derive potential failure modes in a comparison of the EFDM and traditional FMEA for two design examples. This comparison will demonstrate the EFDM’s potential in conceptual design failure analysis.

A large number of sample data is needed to ascertain the characteristic parameters of traditional membership function, so that the calculated fuzzy fatigue reliability based on this method has certain errors for engineering structures without enough samples. A fuzzy fatigue reliability analysis method based on self-configuring membership function is proposed, while considering its multi-source uncertainties in the design, manufacture, and use stage in order to accurately evaluate fatigue reliability of welded A-type frame. In this paper, a novel membership function was presented on account of a small amount of sample data, which some experimental results verified. The mathematical expression for failure probability was deduced from the suggested model, as well as fatigue reliability. Subsequently, the thickness of steel plate defined in design stage, the material properties of weld metal that is produced in manufacture stage, and the loads at different connection sites determined in use stage were all considered as the random variables, which were obtained from Latin hypercube sampling, and the fatigue limit of weld metal was deemed as the fuzzy variable. Based on the response surface method, the fuzzy fatigue reliability performance function was constructed to assess failure probability of welded A-type frame under the condition of downhill and turning braking with full load, while its fatigue reliability was found to be far less than 90%. The fuzzy fatigue reliability optimization that was based on genetic algorithm was implemented, which showed that its reliability varied from 69.47% to 95.12%.
