The paper introduces a methodological approach to optimizing the automated flight data preparation system design process by using organizational and technical measures to minimize the number of design errors and miscalculations of an accidental and deliberate nature. The study proposes to build the structure of the system design process according to the principle “from the general to the particular”, based on which the connections between different stages of design are determined in the form of surjective and bijective correspondences. In the diagram of design stages of the automated data preparation system, each lower level of the hierarchy is a decomposition of the elements of the adjacent upper level into more specific elements. The main methods of improving the quality of system design, methods of semantic control of the correctness of the design decisions, and syntactic control of the correctness of the developed documentation for the design of the automated data preparation system are proposed. The main thirteen problems of system design are considered, which, in practical application, will acquire a more specific form and significantly improve the designed system’s quality.

Purpose Design management plays a significant role in value creation in a construction project. Within the last few decades, new design tools such as building information model have been introduced, which supposedly enhance design productivity and quality. However, no such revolution of design quality has emerged. Therefore, more research on how design management affects the quality of construction project is needed. The purpose of this paper is to better understand the connection between design management procedures and quality. Design/methodology/approach This is a case study with a mixed-method approach. The data collection strategies used are quantitative user satisfaction survey and qualitative analysis over the documentation of the case project. Findings A deductive analysis was conducted to four suggested indicators of beneficial collaboration. An explanation was found for how the quality of the project outcome can be forecasted from the management style and procedures. Research limitations/implications The research was conducted as single case study, and therefore, greater data would enable further development of the indicators. Practical implications The indicators have wide range of applicability: the clients can forecast the quality performance by evaluating the management procedures already during the project instead of waiting until the end of project. The indicator system also provides societal impact as it guides the clients to use the kind of managerial practices that improve the ability to create value in projects that are difficult to evaluate in money terms. Originality/value The research provides a novel way to gain a holistic view with analytical indicator tools. The research contributes to lean design management literature by providing insight to the underlying mechanism of beneficial collaboration.

Purpose The purpose of this paper is to explore activities, challenges, and suggest tactics for the design of industrial reconfigurable production systems that can easily adapt to changing market opportunities. Design/methodology/approach The paper synthesizes the empirical findings of seven case studies including 47 in-depth interviews at four manufacturing companies. Findings A conceptual production system design process and including activities that enables a long-term perspective considering reconfigurability is proposed. Additionally, critical challenges indicating that reconfigurable production system design is not a trivial issue but one that requires separate control and coordination are identified and tactics to overcome the challenges described. Research limitations/implications The authors propose a process for designing reconfigurable production systems that are better suited to adjust to future needs. The knowledge of reconfigurability from the reconfigurable manufacturing system literature is applied in the general production system literature field. This study contributes to a clearer picture of managerial challenges that need to be dealt with when designing a reconfigurable production system. Practical implications By clarifying key activities facilitating a long-term perspective in the design process and highlighting challenges and tactics for improvement, the findings are particularly relevant to production engineers and plant managers interested in increasing the ability to adapt to future changes through reconfigurability and improve the efficiency of their production system design process. Originality/value Although reconfigurable production systems are critical for the success of manufacturing companies, the process of designing such systems is not clear. This paper stretches this by giving a comprehensive picture of the production system design process and the activities that need to be considered to meet these challenges.

Purpose The independence and well-being of people with dementia can be significantly influenced by the design of the physical environments around them. Several assessment tools exist to evaluate the dementia design quality of existing residential aged care facilities but, to date, none have been formally identified as suitable for use during the design process. This paper aims to examine the feasibility of re-purposing existing post-occupancy tools for use during the design process, while mapping the influence of design stages on resulting dementia design quality. Design/methodology/approach Literature searches identified audit tools for residential aged care settings. After reliability screening, three tools were analysed in-depth, mapping their suitability for use during the design process. Findings The study confirmed that existing tools can be re-purposed for design stage use and identified that early design stages have a larger influence on overall dementia design quality than previously thought. Research limitations/implications Non-English language publications were not reviewed. Searches may not have identified other existing audit tools for residential care environments. Practical implications The ability to assess proposals at key stages of design may help improve the dementia design quality of future residential aged care environments – potentially enhancing the lives of ever-larger numbers of people with dementia. Originality/value According to the authors’ knowledge, this is the first known paper to consider formal design-stage evaluation of dementia design quality and the first to identify the relative influence of key stages of design on the resulting dementia design quality.

Buildings can benefit from different system integration working toward the unified goal of providing the needed conditions and improving the comfort level of occupants. It is important to engage all system needs and priorities in the design by keeping goal into consideration. Even though there is vast potential in the coordination of system design decisions, there is a need to increase the transparency of the decision-making process by developing methods to incorporate multi-dimensional design attributes. Design/methodology/approach – This is achieved by considering all system design priorities with respect to decision attributes, as well as the inter-system inputs based on information and knowledge. Data were collected through interviews, collaboration meetings and design document reviews, which helped to facilitate triangulation. Findings – This paper presents the findings of a case study of deep retrofit design process that seeks to reduce energy consumption through integrated system decisions with several system combinations. In addition, such design decisions highlighted the fact that the values need to be flexible at the system level. Research limitations/implications – This paper presents an in-depth analysis of a single case study. Multiple case studies are being investigated for the future of this research. Practical implications – This paper presents the methods used for integrated design process priorities that will enable design teams to make decisions that lead to improved energy performance in retrofit projects. Originality/value – The case study building in this paper is a showcase building with cutting edge technologies and techniques, as well as a scalable and collaborative design process. It is an example of a best-in-class retrofit process designed through whole building design principles within the target budget. The paper demonstrates system design selection criteria that are embraced by value prioritization.
