Abstract

Purpose

The purpose of this paper is to envision the alternative futures of the design and manufacturing industry using an integrated foresight method based on scenario planning. Also, the authors aim at developing robust strategies for an enterprise that aims to be placed as a leading high-tech international design and manufacturing company in 2035.

Design/methodology/approach

The proposed approach is created by integrating several foresight methods such as Delphi, scenario planning, MICMAC and cross-impact analysis.

Findings

Automation and sustainable development are found as the fundamental driving forces in the design and manufacturing industry. Four scenarios based on these driving forces and expert knowledge are created: innovation adaptation, forced automation (business-as-usual), sustainable era and automationless scenarios. For the developed scenarios, a set of strategies are proposed by asking experts about the strategies which can be taken to make the enterprise competitive in all developed scenarios in 2035. The main macro-level outcome is that economic and technological drivers will be the most important factors for design and manufacturing, followed by environmental and social factors.

Originality/value

The proposed method uses the strengths of traditional scenario planning but overcomes its weaknesses by suggesting a systematic process for scenario building and easy application.

Abstract

Purpose

Design of small disc-type permanent magnet (PM) brushed DC motors for servomechanisms is challenging. The purpose of this paper is to propose a special coreless double-sided structure. This easy to manufacture motor has two set of shifted concentrated windings on both sides of the rotor. All of the coils in each winding are simply connected in series. A simple arcless commutator, which shares the features of both the usual commutators and slip rings, is connected to each winding at only two points.

Design/methodology/approach

By replacing the PMs with an equivalent current density, main design equations of the motor have been derived through the solving of scalar Poisson equation. A radial division technique has been used to take the radial variations into account. This provides the ability of considering various shapes of coils and PMs. A novel iterative algorithm has been proposed to design a motor with high torque capability, compared to other coreless counterparts. Some design variables are obtained based on an independent optimization problem, which maximizes the active portion of windings. The other variables are calculated in such a way that the design requirements are satisfied.

Findings

The feasibility and capability of the new structure have been proved by prototyping a sample motor. Comparing the design outputs with the results of the 3D finite element analysis and experimental tests shows a good agreement. This verifies the accuracy of the proposed design method.

Originality/value

A new structure for PM brushed DC motors and a novel algorithm for its design has been developed.

Abstract

Purpose

The purpose of this paper is to characterize and identify the existing studies on the relationship between technological media and development

Design/methodology/approach

The authors conducted a systematic mapping study to identify and analyze the related literature. The authors identified 196 primary studies, dated from 2000 to 2017 and categorized them with respect to research focus, types of research and research method.

Findings

A total of 97 studies were identified and mapped, synthesizing the available evidence on the relationship between technological media and development. “Social development” with 54 articles and “communication” with 34 articles were the dominant research focus. Regarding the research type, “Solution proposal” is the most frequently employed research type. “Case study,” “discussion paper” and “interview,” respectively were the most used research methods. However, “SNA,” “focus group” and “time series” were used less often. “Solution proposal” was the most common research type between 2015 and 2017, and after that “philosophical paper” was the dominant research paper type. Further, the number of publications has increased between 2006 and 2017.

Originality/value

This mapping study is the first systematic exploration of the state-of-art on technological media-development nexus. The existing body of knowledge is limited to a few high quality studies.

Abstract

Purpose

Many devices needed electrical power to work, thus, major energy carriers such as oil and gas were used to generate electrical power via converter mechanisms and special technologies. The microturbine is a developed technology that is remarkable for its relatively high performance and ability to use several types of fuels. Microturbines are economically feasible because of the production of combined heat and power and small-scale applicability. This study aims to investigate microturbine technology development to support modern energy access in a developing country (i.e. Iran).

Design/methodology/approach

This paper presents a technology foresight methodology to create plausible futures of microturbine development in Iran when the country faces different driving forces and uncertainties. On other hand, the paper deals with a theoretical question: how to select appropriate foresight methodology? A procedure is proposed, which equipped the research team to select appropriate method combinations based on Popper’s diamond. Finally, the selected methodology includes defining focal issues environmental scanning and patent analysis aimed at developing five plausible scenarios for microturbine development future in Iran and creating shared visions among policymakers.

Findings

This paper proposed a series of scenarios on the path to developing microturbine technology. The scenario development logic in a participatory way contains a common four-quarter technique that attempts to depict scenarios based on two critical uncertainties inclusive energy price and technology obsolescence, which will shape the future. Also, a scenario is presented to describe a wild card that can disturb the desired futures. Such materials help decision-makers to policies under plausible conditions that guarantee a robust policy basket.

Originality/value

The originality of this paper can be studied based on two aspects, first, the methodology that provides a systematic method selections procedure in an emerging complex technology development program. Second, from the practical aspect, this paper is one of the very first attempts to manage the microturbine technology development program. Then, results are used to feed the policy-making process in Iran.

Abstract

Purpose

Building upon the results of a critical review of previous studies, the purpose of this paper is to present a framework to enhance the reliability of the theoretical model for international benchmarking of labour productivity (TMIBLP) method for construction project activities. The next part of the paper presents the results of implementing the proposed framework for construction activities in the Iranian construction industry.

Design/methodology/approach

This paper draws upon a critical review of the literature to highlight the drawbacks of the previous studies concerning implementing TMIBLP within the construction industry. Identifying these shortcomings, the authors propose a framework for construction projects, which presents the procedure for deploying TMIBLP for construction activities in a reliable manner. The final section of the paper demonstrates the empirical implementation of the proposed framework within the Iranian construction industry.

Findings

The primary contributions of the paper include: identifying the drawbacks of previous studies within the construction context, the framework that would lead construction managers towards more reliable implementation of benchmarking for construction projects, and determining the baseline of erecting steel structures in a developing country.

Practical implications

A practical implementation of the TMIBLP method was presented to address the lack of research in Iran and to show the feasibility of using the framework developed. The authors investigated the daily labour productivity for the activity of structural steel erection for six projects in Tehran in order to determine the values of the baseline productivity for each project. Accordingly, the disruption index, performance ratio and project management index as the project benchmarks were calculated for all six projects.

Originality/value

Underlining the necessity of implementing methods such as TMIBLP, this study outlines the outcomes of the first study on the benchmarking of construction activities deploying the proposed framework and using the data on erecting steel structures from six construction projects in Iran. The discussions provide guidelines for construction project managers regarding benchmarking labour productivity. The paper concludes with suggestions for future research opportunities.

Abstract

Purpose

The purpose of this paper is to describe the current status of the knowledge-based economy (KBE) in Iran in comparison to Turkey, the challenges encountered and the appropriate policies toward Iran’s Outlook 2025 based on which the country is expected to be ranked first in science and technology within the Middle East region.

Design/methodology/approach

This study is a descriptive research. The methodology used for this study is qualitative/quantitative secondary research. The method will be used for two main goals. First, we used the World Bank’s Knowledge Assessment Methodology, and the data are mostly collected from secondary sources such as the World Bank’s Development Indicators for Iran and Turkey. Second, desktop research will be used to summarize and synthesize available studies on the consideration of policy-making toward KBE, especially among developing economies.

Findings

The paper provides policy considerations around four pillars: information and communications technology (ICT), innovation system, education and human resources development and economic incentives and institutional regime. It suggests that regarding ICT indicators, Iran has to join international programs to attract senior public authorities’ involvement and accountability. Regarding its innovation system, lessons for policymakers are implementing development plans and coordinating science and technology policies in the country. Moreover, the quality of education, in-company training, post-secondary technical education and scientific and technological workforce need to be improved. Finally, considering the weak macroeconomic circumstances, legislative measures are needed in addition to, establishing a promotion agency for foreign direct investment to coordinate the inflow and to grant incentives for attracting more investment.

Research limitations/implications

Because of the chosen research approach, the research results have not been confirmed by an experts group. Therefore, using some group decision-making methods, such as panel of experts, could be proposed to further test the findings.

Practical implications

The paper includes implications for public policymakers, especially in developing countries, and for moving toward a KBE.

Originality/value

This paper fulfills an identified need to learn from similar countries experiences in policymaking about the same problem.

Abstract

Purpose

The purpose of this study is to formulate exploratory scenarios of Operations Research through the critical uncertainty approach and Soft Systems Methodology.

Design/methodology/approach

In this study, to formulate plausible scenarios, the discipline of operation research internal and external experts’ opinions of this field have been gathered through Delphi approach and uncertainty questionnaires. After use of the most important uncertainties, plausible scenarios of operations research have been mapped with the help of experts through co-thinking workshops.

Findings

Four scenarios are presented in this study. These scenarios include Solar System, Esfandiar's Eye, Rival’s Setraps and Legendary Simurgh. Naturally, the imagination of such a unitary future for all academic communities is an expectation far from reality, and given the conditions of each of these futures or any integration of them is imaginable.

Originality/value

Operations Research models have been faced with variously multiple changes since its emergence until now. Investigation into the future of operations research on the necessity for his planning has not received a reasonable notice in the literature. Sporadic activities that have been carried out are also lacking in the necessary methodology. Also, there has been no research about future study using the soft Operation Research tools (Soft Systems Methodology).

Abstract

Purpose

The objective of this paper is to propose a new data envelopment analysis (DEA) model for assessing sustainability of suppliers with partial impacts between inputs, desirable outputs and undesirable outputs.

Design/methodology/approach

This paper examines partial impacts of inputs on desirable and undesirable outputs and applies weak disposability assumption to propose a novel DEA model to determine the sustainability of suppliers.

Findings

This paper shows the type of resource sharing in DEA models and takes into account sustainable development and sustainability assessment concepts for sustainable supplier selection problem and develops a DEA model for selecting the most sustainable suppliers with partial sharing of resources. To select the most sustainable suppliers, this model helps managers to consider aggregate efficiency, overall efficiency and bundle efficiency. The paper introduces the supplier which is efficient at all levels as the most sustainable supplier.

Originality/value

For the first time, this paper suggests a new DEA model by partial impact between inputs and good outputs/bad outputs for selecting sustainable supplier and deals with the situations in which each supplier has several subunits. The new model calculates aggregate efficiency, overall efficiency and subunit efficiency of supplier. paper introduces the supplier which is efficient in all levels including aggregate efficiency, overall efficiency and subunit efficiency as the best supplier.

Abstract

Purpose

Current models of organizational excellence are appropriate for the private organizations. It is evident that if an appropriate model is not adopted, the process of excellence in the organizations fails and some dimensions of the organization get affected by unpredictable damages. This research aims to identify an appropriate excellence model for public organizations.

Design/methodology/approach

First, a comprehensive literature review was conducted to identify the excellence criteria and models. Second, the models were through an expert-oriented questionnaire, analyzed by the analytical hierarchy process (AHP) technique. Participants were experts in the two domains of excellence models and public sector management. A sample of 15 experts was selected using purposive sampling. In order to emphasize on reliability, 10 questionnaires were adopted for analysis.

Findings

The findings showed that the European Foundation for Quality Management (EFQM) model is the most appropriate model for excellence measurement in the public organizations based on the five selected indices.

Originality/value

The identification of a model for measuring organizational excellence for public sector can significantly contribute to existing literature on excellence measurement.
