Digital Twin

The problem of optimal allocation of resources in limited circumstances to handle assigned tasks has been dealt with in a wide variety of research fields. Various research methodologies have been proposed to address uncertainties such as waiting and waste in construction projects, but they do not take into account the complexity of construction production systems. In this study, a research approach was proposed that simplified the construction production system into a work package to be serviced and a work group to provide services. In addition, a conceptual 4D digital twin framework considering the uncertainty of the construction production system was proposed. This framework includes BIM as an information model and a queuing model as a decision-making model. Through case projects, we have presented how this framework can be used for decision making in several statuses. As a result of the analysis using the performance index of the queuing model, it was possible to monitor the status of the system according to the allocation of resources. In addition, it was possible to confirm the improvement of the performance index according to the additional arrangement of the work group and the activity cycle of the work package. The framework presented in this study helps to quantitatively analyze the state of the system according to the input data based on empirical knowledge, but it has a limitation in that it cannot present an optimized resource allocation solution. Therefore, in future research, it is necessary to consider the grafting of machine learning technology that can provide optimal solutions by solving complex decision-making problems.

- The key question in diversity research concerns the effects of diversity on Work Group processes and work group performance. In this setting most of research has been performed according to two distinct perspectives, the social categorization and the information decision making. So far however, the research has yielded ambiguous results: diversity seems to have positive as well negative effects on work group work group outcomes (Milliken, Martins, 1996; Brewer, 1995; Guzzo, Shea, 1992; Jehn, Northcraft, Neale, 1999; Triandis et al.,1994). Recently, van Knippenberg, De Dreu, Homan (2004) proposed the Categorization Elaboration Model CEM (van Knippenberg et al., 2004; van Knippenberg, 2007), which deals with those ambiguous results by incorporating as well as integrating the social categorization and the information decision making perspectives. The model set an agenda for future research in work group diversity.

Purpose – The purpose of this paper is to implement an integrated activity-based costing (ABC) and theory of constraints (TOC) approach to enhance decision making in a Lean company. Design/methodology/approach – Based on the literature, this paper proposes an integrated ABC and TOC approach and applies it to a Lean plastic manufacturing company to improve its product-mix decision. Findings – The results of the case study show that the current conventional product-mix decision used by the company and the proposed integrated approach can give significantly different results concerning the optimal product-mix and the associated bottlenecks. Moreover, the paper suggests that managers who implement Lean production without utilising a supportive management accounting system may experience disappointing financial results. Research limitations/implications – The validation of the suggested method is based on a single case study with an action research approach. For future research, the authors suggest the implementation of the approach in different industries. Practical implications – Overall, the integration of ABC and TOC provides managers with an accurate, timely and reliable tool that can help in making decisions about pricing, production line development, process improvements and product-mix. Originality/value – This paper contributes to Lean and management accounting literature by demonstrating the value of a method of integrating ABC and TOC. Also a case study is chosen for the empirical aspect of the study as there are no case studies available in the literature that illustrate a real life case of integrating ABC and TOC within Lean companies as an alternative to the current used cost accounting systems.

This strategy is intrinsically analyzed and evaluated with respect to the strategic business environments. Design/methodology/approach The objective of this research is to analyze the advantages and limitations of the outsourcing that have been identified in prior studies. This research has attempted to investigate the performance implications of outsourcing strategies in terms of theoretical considerations and implementation perspectives. Findings In this study, the authors have presented a general overview of outsourcing strategies in terms of both light and dark sides of this approach. Various driving forces of outsourcing strategy along with critical success factors are articulated within project to product development perspectives. Research limitations/implications Future research could be continued to measure various performance variables such as productivity, sales, revenues, career opportunities, manifest in power struggles, change jobs, change organizational cultures, etc. in multiple case companies, which affect with the success or failure of outsourcing arrangements. Practical implications The term outsourcing is nowadays a widely known business strategy, where manufacturing firms share partly or fully of their production process with outside organizations or suppliers. The research approach as articulated within this paper would be beneficial for project business organizations and specially the product designers and project managers for planning and developing their strategic business potentials with respect to outsourcing and in-sourcing decisions. Originality/value In this paper a high-level decision-making model for outsourcing and a cause and effect type framework are demonstrated with a view to ease the decision-making process for the organizations managers.

Manufacturing Environments

The application of digital twins provides value creation within the fields of operations and service management; existing research around decision-making and value co-creation is limited at this point. Prior studies have provided insights into the benefits of digital twins that combined both data and simulation approaches; however, there remains a managerial gap. The purpose of this paper is to explore this research gap using input from a multiple case study research design from both manufacturing environments and non-manufacturing environments. The authors use ten cases to explore how digital twins support value co-creation through decision-making. The authors were all involved in the development of the ten cases. Individual biases were removed by using the literature to provide the assessment dimensions and allowing a convergence of the results. Drawing on the lessons from the ten cases, this study empirically identified eight managerial issues that need to be considered when developing digital twins to support multi-stakeholder decision-making that leads to value co-creation. The application of digital twins in value co-creation and decision-making is a topic that has developed from practice and is an area where a research gap exists between theory and practice. A cross-case analysis was developed based on the literature and the ten cases (eight industrial and two pilot-scale cases) providing the empirical findings. The findings describe how firms can design, develop, and commercialize digital-twin-enabled value propositions and will initiate future research.

AbstractEach industrial automation project includes tasks that strongly depend on human factors, many of which may belong to the critical path or chain of the project. Multitasking significantly affects human productivity. The reduction in productivity has a direct result of delaying the primary task, which may cause an overall delay to the project with cost and time overruns. A project should be seen with respect to a global environment, such as that of a company, where resources are shared among its portfolio of projects. Although multitasking might have negative results, it is something that cannot be eliminated but can be mitigated by project managers.This article presents the effects of multitasking on human productivity, especially when the tasks are complex, like programmable logic controller (PLC)/supervisory control and data acquisition (SCADA) software development. Using the analytical hierarchy process (AHP) method, a simple tool is created to be used by project managers, in order to assist them in decision-making. Criteria that influence these decisions are referenced, and their priority vectors are proposed. In addition, some real examples are given.Project managers face a complex situation when they are asked to decide on the allocation of resources and priorities among different projects. Parameters that are difficult to predict in real situations may have a significant role in the decision-making process.There are a lot of published works based on AHP applications in different fields, but there is a gap in the field of industrial automation projects and the related project manager’s decision-making. This study focuses on these decision-making processes that determine which tasks should be paused or not for a better allocation of resources, taking into account the global environment of a technical company. The tool can be implemented with changing criteria and priority vectors to adapt to different types of projects. Future research could identify additional criteria and subcriteria with different priority vectors, depending on different project specifications.This article is the extended version (Part II) of CCC 2017 Procedia Engineering paper.

PurposeThe purpose of this article is to introduce a theoretical framework and approach for studying the evaluation and decision-making practices through which academic librarians attempt to reduce the cost of electronic journal subscriptions – an organizational practice known as the unbundling of big deal journal packages.Design/methodology/approachThe article presents a literature-based conceptual analysis of several fields to delineate the elements of the practice of unbundling of big deal journal packages. Beyond analysing the prior literature, the discussion is supported by empirical findings from a pilot study on the topic conducted by two of the article's authors.FindingsThe main finding of the article is that the unbundling of big deal packages is a case of what sociologist refers to as decision-making in a social context. By reviewing previous studies, the article identifies the social and material elements constitutive of this practice. This, in turn, allows to develop questions and concepts for future research on the topic and to position it as an area of inquiry within the field of information behaviour/practices.Originality/valueThe article is the first attempt to conceptualize the unbundling of big deal journal packages by highlighting its phenomenological status as a type of information practice. In addition, the article proposes a research approach for studying this type of information practice by drawing on insights from the information behaviour/practice literature and enriching them through practice theory contributions in organizational studies and sociology.

Theoretical Idea

BACKGROUND Decisions regarding telehealth services in Quebec (Canada) have been largely technocratic by nature for the last 15 years, and the involvement of citizen-patients in the development of telehealth services is virtually nonexistent. In view of the societal challenges that telehealth raises, citizen-patient involvement could ensure more balance between evidence from traditional research methodologies and technical experts and the needs and expectations of populations in decisions about telehealth services. OBJECTIVE This study aimed to explore the perception of various stakeholders (decision makers, telehealth program and policy managers, clinicians, researchers, evaluators, and citizen-patients) regarding the involvement of citizen-patients in the development of telehealth services in Quebec. In particular, we explored its potential advantages, added value, obstacles, and challenges it raises for decision making. METHODS We used a qualitative research approach based on semistructured individual interviews, with a total of 29 key actors. Respondents were identified by the contact network method. Interviews were recorded and transcribed verbatim. A pragmatic content thematic analysis was performed. To increase the capacity for interpretation and analysis, we were guided by the principle of data triangulation. RESULTS Citizen-patient involvement in decision making is perceived more as a theoretical idea than as a practical reality in health care organizations or in the health system. There is very little connection between citizen involvement structures or patient and user groups and telehealth leaders. For the respondents, citizen-patient involvement in telehealth could increase the accountability and transparency of decision making and make it more pragmatic within an innovation-driven health system. This involvement could also make citizen-patients ambassadors and promoters of telehealth and improve the quality and organization of health services while ensuring they are more socially relevant. Challenges and constraints that were reported include the ambiguity of the citizen-patient, who should be involved and how, claimant citizen-patient, the risk of professionalization of citizen-patient involvement, and the gap between decision time versus time to involve the citizen-patient. CONCLUSIONS This study provides a basis for future research on the potential of involving citizen-patients in telehealth. There is a great need for research on the issue of citizen-patient involvement as an organizational innovation (in terms of decision-making model). Research on the organizational predisposition and preparation for such a change becomes central. More efforts to synthesize and translate knowledge on public participation in decision making in the health sector, particularly in the field of technology development, are needed.

Corporate Farming

The use of pasture measurement tools and decision-support systems (DSS) for grazing management remains limited on New Zealand dairy farms. However, effective use of such tools provides opportunities to optimise pasture grown and pasture harvested. The present study used a mixed-method qualitative research approach to investigate pasture data and technology use for grazing decision making, through interviews and workshops with farmers, rural professionals, commercial software developers and a panel of farming-system specialists. Results suggest that different drivers for use of pasture data and DSS exist between farm owner-operators and corporate farming operations. Larger multi-farm businesses are collecting pasture data for use at a governance level as well as for operational decision making. Understanding the seasonal influences on decision making, and incorporating major regional differences such as pasture growth rates and impact of irrigation use, provides guidance on how to better match DSS to farmer practice. Study participants identified a need for greater integration of software tools to connect in-paddock data capture with real-time feedback. Also, data integration is needed to enable the transfer of information across different platforms for corporate farming operations. Rural professionals used commercial grazing DSS products, but also constructed their own spreadsheets to enable functionality and reporting not available in the DSS products. The research highlighted a need for farmer-orientated tools that are flexible to incorporate differences in user goals, decision making, mobility and desired outputs. Key attributes identified were seasonality, simplicity, ability to trial before purchase, flexibility in application, scalability to match farm systems, and integration with other tools. Future research and design of DSS tools requires a focus on co-creation with farmers, to merge scientific and practical knowledge.

In academic and practitioner literature, codes of ethics are generally understood to act as a mechanism guiding and ensuring ethical behaviour. However, this premise has not yet been thoroughly explored. Using a qualitative research approach this study examines the tools used in ethical decision-making by New Zealand marketing research practitioners, with a focus on client relationships. Participants reported on their awareness, familiarity, and use of professional and organisational codes of ethics. In particular, information was sought on how ethical issues were dealt with when they arose in their relationships with clients. This empirical research focused on the effects of different variables and emerging constructs, and the interplay between them, on ethical decision-making in client relationships. The paper concludes with a discussion of research contributions, implications for the practice of marketing research, and future research opportunities.
