Purpose The purpose of this paper is to propose a hybrid decision-making model for optimizing the initial design strategies of pre-sales housing, identifying factors affecting the initial design of housing, and developing different initial design approaches and strategies based on buyers’ preferences. Design/methodology/approach Indicators and factors in line with the local initial planning and design are created according to the design quality indicator framework. The important indicators and factors are screened out preliminarily with the fuzzy Delphi method and decision-making trial and evaluation laboratory based analytic network process. The performances of two actual cases under similar site conditions are checked with regard to the overall residential sales rate and time on the market (TOM). Findings The result shows that the proposed model can effectively improve the sales rate, shorten the TOM and better complies with buyer design strategy demands, and thus positively correlating to economic value. Originality/value Pre-sales make possible the customized strategy of allowing future residents to participate in the housing design process. However, buyers’ participation in the design process is highly limited, and developers usually determine their planning and initial residential design strategies based on experience and intuition. With the proposed approach, the initial residential design of a project can be effectively intervened, so that home users can truly participate in the design, and the residential construction service can be provided in a unique, but non-universal way.

PurposeThis paper proposes a multi-layer hybrid decision-making approach to evaluate the capability alternatives for developing a collaborative network to operate in the international market.Design/methodology/approachThe present study is contextualised in the Iranian pistachio export industry. An extensive review of the state-of-the-art literature on supplier collaboration was conducted to identify key capabilities that are essential to establish a collaborative network. The set of defined capabilities were then optimised through interviews with 14 experts from the relevant industry, academics and export authorities. A combination of the fuzzy Delphi method and the best–worst method (BWM) approach was, respectively, used to reduce the number of capability alternatives and assign priority weights to these alternatives. Subsequently, a weighted aggregated sum product assessment method (WASPAS) was employed to rank and evaluate the ability to creating a collaborative network for the export of pistachio.FindingsFrom the extant literature review, 18 capabilities for the formation of coordination networks in the international markets were identified. Then, the prominent indicators in forming a global network were extracted. After ranking the top pistachio export countries/regions to formalise an efficient collaborative network, it was revealed that although Iran exports approximately 30% of the global market, it falls behind the USA and European Union. The competitors have scored higher in critical criteria, including “trust and commitment”, “strategy and management”, “managerial control and standardization” and “financial resources”.Originality/valueThe proposed hybrid approach encompassing fuzzy Delphi–BWM–WASPAS offers to solve the capability evaluation and selection as well as ranking the possible alternative to formalise a collaborative network in an integrated fashion. This combination of methods is capable to first identify the most important factors, then measuring their importance and eventually rank the possible alternatives. The suggested framework provides an approach to deal with the uncertainty of global collaborative network formation.

Decision Making Model

Purpose Supplier selection for capital procurement is a major strategic decision for any automobile company. The decision determines the success of the company and must be taken systematically with the utmost transparency. The purpose of this paper is to construct capital procurement decision-making model to optimize supplier selection in the Indian automobile industry. Design/methodology/approach To achieve the stated objective, a combined approach of fuzzy theory and AHP-DEMATEL is applied. Evaluation parameters are identified through an extensive literature review and criteria validation has been introduced through a Fuzzy Delphi method by using fuzzy linguistic scales to handle the vagueness of information. AHP is employed to find the priority weight of criteria, although an inter-relationship map among criteria is not possible through AHP alone since it considers all criteria as independent. To overcome this, DEMATEL is used to establish cause-effect relationships among criteria. Findings The results show that the total cost of ownership (TOC) is the first weighted criterion in supplier selection for capital procurement, followed by manufacturing flexibility and maintainability, then conformity with requirement. The cause-effect model shows that supplier profile, TOC, service support and conformity with requirement are in the cause group and are considered to be the most critical factors in selecting the supplier. Originality/value The study’s outcome can help the automobile industry to optimize their selection process in selecting their suppliers for capital procurement; the proposed model can provide guidelines and direction in this regard.

Product Design Process

The product design process plays a central role in ensuring that new products are realized with improved quality, in a short lead-time and with costs kept to a minimum. It is identified that making decisions dynamically on how the design process should proceed is not trivial. A computational environment that aids dynamic decision making on the design process would be useful in ensuring successful design of new products. A key component of analysing and making decisions on the progression of the design process is a model that captures an ongoing design process. In this paper, an approach to modelling an ongoing design process is proposed based on the use of design nodes. The approach allows an ongoing design process to be modelled that facilitates dynamic decision making on how the design process should progress and accounts for the state of the design problem. The approach allows top-down and bottom-up design strategies to be modelled.

PurposeTo design a novel hybrid approach to illustrate a reciprocal alignment to integrate future products and technologies. This mixed qualitative-quantitative method aims to optimize the final product portfolio and production technologies alignment in the food industry.Design/methodology/approachA list of products and technologies is extracted and evaluated by experts employing Market Attractiveness and Ease of Implementations Matrix (MA-EI) for products and attractiveness and technological Capability Matrix (A-C) for technologies. Weights of high-scored alternatives are attained applying the Z-number extension of Best Worst Method (ZBWM). After the product-technology matrix is formed and the alignment scores of each pair are determined by experts. Subsequently, final scores are computed, and a framework is proposed by electing high-ranked products and technology of each cluster to form the aligned product and technology portfolios of a food and hygiene industry company.FindingsBy employing an uncertain multicriteria decision-making approach besides product and technology matrices in a food industry corporation, among 40 technology and product, 13 products by 6 technologies are proposed. Thus, only six technology are necessary to manufacture the highly important and effective products.Originality/valueThe combination of product and technology analysis matrixes with an uncertain decision-making approach is considered as a novel approach in this research. Moreover, the distinctness between the present study and other researches is the concurrent unified aspect of product portfolio and technology optimization and its implementation in the planning discussion, especially in the food industry.

Hierarchy Process

Purpose Service supplier selection is a multi-criteria decision-making (MCDM) problem assuming a strategic role for the competitiveness of high-tech manufacturing companies. Nevertheless, especially for service quality evaluation, there is little empirical evidence of the practical usefulness of MCDM methodologies. Aiming to cover this gap between theoretical approaches and empirical applications, the purpose of this paper is to propose a fuzzy extended analytic hierarchy process (FEAHP) approach for service supplier evaluation. Design/methodology/approach A hybrid approach which combines some of the strengths of the analytic hierarchy process (AHP) and of the fuzzy set theory is presented, as organized into five steps. A case study is used to evaluate the applicability in a real company context. Findings The usability of the approach is demonstrated in an aerospace company for solving the supplier selection problem of a business software whose applications are still in infancy: a Test Data Management System (TDMS). The illustrative application contains both “general” criteria to be used for other service supplier selection contexts as well as service-specific criteria related to software selection. Research limitations/implications Even if the application regards the selection of a software supplier, the methodology can be generically extended to other services’ selection in complex manufacturing industries through the personalization of some criteria. Practical implications Implications can be derived both for business managers involved into the decision-making process and for suppliers identifying the most promising features of software quality. Originality/value The originality consists in the combination into a hybrid approach of the strong points of the AHP with the fuzzy set; the inclusion of multiple perspectives of decision criteria for service supplier selection, basically the “software product” and “supplier” ones; a real empirical application to test and demonstrate the efficacy and the practical utility of the proposed approach.

Purpose Managing across cultures is vital for international business success. Leaders need to make decisions in a way that suits the new culture in which they are placed. This paper aims to explore how expatriate managers in the UAE make decisions in respect to their contextual environment. Additionally, the study investigates the approaches expatriate managers use to adjust their decision-making and how they manage local staff in contrast to home country staff. Finally, the study investigates the factors that contribute to the situation-specific environment of the expatriate leaders’ experience. Design/methodology/approach Structured personal interviews of expatriates drawn from stratified sampling were used to discover the styles of decision-making that were effective in the UAE. Findings The consultative management style of management enhanced by a hybrid approach of melding the strongest aspects of the expatriates’ decision-making style with the strongest aspects of the local decision-making style met with much success managing in the UAE. Additionally, the expatriate managers’ expression of appreciation towards local staff provided motivation and encouraged cooperation. Moreover, it was found that expatriates can face difficulties in expressing their wishes and requirements accurately to local staff because of their unfamiliarity with the Arabic language. Practical implications This research provides practical guidance for expatriate managers charged with successfully leading organizations in UAE. It also offers guidance for employers seeking to recruit or employ appropriate management talent to UAE. Originality/value The paper concentrates on expatriate managers’ decision-making practices within the UAE.

AbstractThe paper presents the influence of Key Performance Indicators (KPI) on decision making during the architectural design process. In the beginning, the researcher selected a functional complex of industrial nature for the test and defined five criteria for evaluating the architectural design and then created two categories of result and process indicators to explore the decision making during the design process through Verbal Protocol Analysis (VPA). Two groups of subjects attended the VPA, while one group received the indicators; the other one did not receive the indicators. The protocols were transcribed and encoded to make the comparison more efficient. At the same time, the jury evaluated the sketches separately to check the previous results. The study indicates that the indicators were affecting the decision making and design process and design product simultaneously. First of all, framing decisions were made more organized and mature and at the same time increased in numbers, the key decisions were evaluated easier and in some cases divided into smaller decisions related to one or more criteria and then merged into a final concept, the enabler decision making was done more efficiently and faster because of better thought key decisions and the use of indicators for control. The design process, although still has iterative nature. However, iteration was done in smaller cycles due to the use of result indicators for evaluation and process indicators to lead the process. Indicators facilitate idea generation, and the whole process is without difficulties. The design quality assessment by the jury shows the improvement in the final quality of design outcome in specific aspects related to indicators.

Purpose The purpose of this paper is to study the design process innovations that enabled the successful delivery of a hybrid, mass-timber high-rise building in Canada, the Brock Commons Tallwood House at the University of British Columbia. It is one of a set of papers examining the project, including companion papers that describe innovations used during the mass timber construction process and the impact of these innovations on construction performance. Design/methodology/approach A mixed-method, longitudinal case study approach was used in this research project to investigate and document the Tallwood House project over a three-year period. Both quantitative and qualitative data collection and analysis techniques were used. Graduate student researchers were embedded within the project team to observe meetings and decision-making and to conduct periodic interviews. Findings The research highlights a case of a balanced triple-helix system that provided a context for the successful “clustering” of product and process innovation, which were developed and implemented to flow throughout the project’s lifecycle and across its supply chain to provide benefits at each stage. Four significant process-based innovations were implemented at the design phase of the building project to support radical product innovation: an integrated design process, virtual design and construction, designing for manufacturing and assembling and a rigorous quality control and quality assurance process. The product innovations developed through these process innovations were the structural system and the prefabricated envelope system. The context of innovation was seen to allow this “clustering,” which is believed to be a key condition of success and enabled the efficient and successful delivery of the project. Generally, the approach was successful; however, some factors including the number of stakeholders and good-faith collaboration may limit the replicability of these strategies. Originality/value This paper presents an in-depth investigation into the instantiation of an innovation system, identified as a balanced triple-helix system, which enabled and facilitated the design and decision-making process for a radical product innovation. Moreover, this paper describes the deployment of a “cluster” of process innovations that flowed throughout the project’s lifecycle and across the project supply chain. This was seen as a key factor in ensuring the successful delivery of the project.

Combining with the differences of traditional houses between northern and southern parts of China, this paper argues that different choices of low-carbon housing design should be chosen to adjust to different climate conditions, in which geographic characteristics and economic status should be considered. Such designs can not only reflect geographical characteristics, but also reduce the construction costs of low-carbon housing effectively, and they are also in line with local economic development. And the paper also explores viable design strategies which can adjust themselves to low-carbon housing design in Nanjing.
