A House of Quality (HOQ) matrix of assistive technology for deaf students at elementary school to enhance basic-level language competencies

Communication skill is a human basic ability to interact with one another. People usually have no difficulties in communication, yet not for deaf people. The basic communication ability of deaf people tends to be poor due to their hearing impairment. Thus, the technological role is an effective way to enhance communication skill for deaf people or so-called as assistive technology. This study generated a house of quality (HOQ) matrix which can be adopted to develop an assistive technology in the form of language instructional media. The HOQ matrix generated significantly contributes to translating from profound need analysis to assistive technology features to enhance communication ability through Indonesian language competencies for deaf students at elementary school. The user needs were formulized from a preliminary assessment at previous research which took twelve best deaf students from three special elementary schools in Special Region of Yogyakarta, Indonesia. This study has found that the priority of assistive technology development is visual and interactive media, either application or educational game, which comprises the vocabulary of concrete thematic nouns and non-affix transitive verbs and composing a simple sentence. Therefore, the HOQ generated is particularly noteworthy for Indonesian language major competencies by deaf students, which are: understanding reading text skill, writing, and speaking.

Using Quality Function Deployment Approach to Design Ready to Drink Beverage Bottles

Due to its role and usefulness in enhancing the product 's consistency, beverage product packaging is important and also has the appeal of a ready-to-drink. In the beverage industry, the degree of competition in packaging is very intense, and the requirements for practicality promote the design of new beverage packaging bottles that meet customer needs using the Quality Feature Deployment (QFD) process. Ready for drinking category bottle (RTD) is the design of beverage bottles produced. The choice of methods for the QFD approach is based on the participation of consumers in the product design sequence as early as possible to ensure that the product will please customers. Research started with the dissemination of the initial questionnaire, the preparation of the customer's speech, the dissemination of the second questionnaire, the determination of the customer's needs, the decision on technical characteristics, the formation of a quality house (HOQ) and the production of a visualized design. Round, pet (Polyethylene Terephthalate), bottle height 175 mm, bottle base diameter 61.65 mm, bottle body diameter 59.95 on the bloated body are the resulting RTD beverage bottle shape. In comparison, the diameter of the shrinking body in the middle is 53.24 mm, the height of the neck-to-hole is 15.63 mm, the diameter of the hole is 24.38 mm, the diameter of the cap is 30.63 mm, the weight of the light bottle is 20 grams, the width of the label is 40 mm, the length of the label is 100 mm and the colour of the blue and green label with flip and slide versions. The innovation in the design of this RTD beverage bottle is that by separating the two sides vertically, it can accommodate two types of drinks in one bottle (2 in 1 bottle), each side can accommodate 250 ml, and the suggested types of drinks are mineral water and tea from the survey results.

System development for the configuration of learning factories

Learning factories represent realistic learning environments for academia and industry in order to develop competencies. The design of learning factories can be facilitated by a configuration system. The configuration of a learning factory describes the selection of factory elements and products. Mathematically this selection can be described by an optimization problem based on a utility function and restrictions. Optimization algorithms facilitate the planning process by selecting the feasible combination of factory elements with the highest utility. This paper describes the methodology to develop a configuration system for learning factories. Customer needs for the configuration system were identified by an explorative stakeholder study: Learning factory developers, operators, and trainers were interviewed with open and partially open questions. These customer needs were then evaluated regarding their importance. The relationship between customer needs and functional requirements is described in a House of quality. To determine the system design systematically, the decomposition principle and the zig-zag process of the Axiomatic Design were applied. Axiomatic Design is a method to design engineering systems including complex systems and software. Consequently, the functional requirements were transformed into design parameters. Design parameters characterize the design of the configuration system.

Supply chain analysis of e-waste processing plants in developing countries.

e-Waste is generated at the staggering rate of 6.1 kg per person. In 2016, 44.7 million tonnes was generated globally, and the amount is estimated to reach 52 million tonnes annually by 2021. The management of this huge quantity of e-waste is a major problem across the world, primarily in developing countries. An effective e-waste management system is linked to the sustainability of e-waste processing plants, and currently it is plagued with different supply chain network (SCN) issues. To address the issues and challenges of SCN, there is a need to prioritize and address the constructs. The study thus combines two multiple criteria decision making (MCDM) tools, the analytical hierarchy process (AHP) and quality function deployment, to prioritize the constructs identified from literature and supported by field studies. The house of quality (HOQ) has been used for analyzing different stakeholders' requirements. The degree of importance for HOQ-1 has been derived using the AHP tool. The study revealed the most intriguing issues and challenges of e-waste processing plants considering the requirements of different stakeholders. The results showed formal collection, storage, semi-informal collection, and e-waste quality to be the major issues of processing plants. The findings obtained from MCDM analysis have been validated though two case studies in India and China. If the results obtained are applied to the existing e-waste SCN, a holistic e-waste management system can be achieved for developing countries.

QUALITY RESEARCH MANAGEMENT IMPROVES DESIGN RESEARCH EFFECTIVENESS

Design research projects are often more complex than initially perceived due to a requirement for novelty, the creativity inherent in the design process, and the limited experience of novice researchers. Also, expectations from institutions and external funding stakeholders must be met. Therefore, a framework was needed to support the research effort in the form of quality research management. The focus of this framework is primarily to align stakeholders. To this end, engineering management methods were consulted to define a quality research management framework that provides review baselines, requirements traceability, and a general process model. The framework is based on the well-known ‘house of quality’ principle that provides requirements traceability. A series of matrices was developed, with a research validation matrix resulting from the combination of traceability matrices. This matrix allows the allocation of research challenges to a need, concept solutions to research challenges, and specific research solutions to concept solutions. Also, information sources are allocated to challenges and solutions to verify their authenticity. It is thus possible to visualise clearly a summary of the research project. Additional benefits include improved communication, visualisastion of progress, traceability of requirements, and verification and validation, which illustrates the value of quality research management.
