Purpose This paper aims to propose a model to assess leagile strategy effectively as one of the most discussed production and supply chain strategies. Design/methodology/approach This research is based on an integrated FLinPreRa-FQFD approach, which ranks and determines the importance of criteria and indices of the proposed model in an effective way. Findings “Cost” has been taken as the most important competitive advantage in the four selected industries. “Customer and market sensitiveness” has been considered as the most important enabler in three industries (“machinery and equipment,” “textile” and “food and beverage”). “Collaborative relationship” has been also considered as the most important enabler in the “material and chemical products” industry to gain leagility. Practical implication On the one hand, the proposed research model can be used as a reference guide for firms to reach leagility. This model presents indices of leagility at different levels. On the other hand, with respect to the main activities of the Iran Chambers of Commerce, Industries, Mines and Agriculture, including Qazvin’s, committed to provide requirements for economic development, this work provides an opportunity for the implementation of leagility model in 151 active companies. It also gives new insights into the leagility application in the four industries and Qazvin’s Chamber of Commerce, Industries, Mines and Agriculture. Originality/value This research has two main contributions. First, it presents a model of enablers and attributes of leagility, combined with four competitive advantages. Second, the research study is equipped with an integrated and consistent methodology that, first, helps decision makers prioritize their goals and agenda by means of fewer paired comparisons without the need of consistency rate and, second, allows for direct evaluation of impact of enablers on attributes of leagility.

Purpose The purpose of this paper is twofold: first, to revise the Kano model with a focus on one-dimensional attributes; and second, to use the revised model for categorizing and prioritizing various employee compensation strategies. Design/methodology/approach The Kano evaluation table has been revised and the one-dimensional attribute has been further extended to three categories of OO, OM and OA. In the next step, the literature review-based identified strategies have been categorized and prioritized according to the developed Kano model. Consequently, an employee compensation system has been proposed to a process-based manufacturing company as a case study. Findings Findings indicated that out of the 44 employee compensation strategies, typically 6 were must-be, 13 were one-dimensional, 18 were attractive and 7 were indifferent. Also, the results of the revised Kano model indicated that typically out of the 13 one-dimensional strategies, 7 were one-dimensional tending toward must-be (OM); and 6 were one-dimensional tending toward attractive (OA). Research limitations/implications The case study was limited to one company. The validity of the proposed model can be further studied in a larger population. This study provides managers with a more accurate instrument of decision making in selecting more differentiated employee compensation strategies, which, in turn, might lead to more employee satisfaction. Originality/value Theoretically, this study is different from existing studies, since almost none of the previous studies extended the Kano evaluation table for one-dimensional attributes. Practically, this study is another evidence of the application of the Kano model in the field of human resource management and in particular contributes to the design of employee compensation systems.

Proposed Model

PurposeThis paper proposed a bi-level mathematical model for location, routing and allocation of medical centers to distribution depots during the COVID-19 pandemic outbreak. The developed model has two players including interdictor (COVID-19) and fortifier (government). Accordingly, the aim of the first player (COVID-19) is to maximize system costs and causing further damage to the system. The goal of the second player (government) is to minimize the costs of location, routing and allocation due to budget limitations.Design/methodology/approachThe approach of evolutionary games with environmental feedbacks was used to develop the proposed model. Moreover, the game continues until the desired demand is satisfied. The Lagrangian relaxation method was applied to solve the proposed model.FindingsEmpirical results illustrate that with increasing demand, the values of the objective functions of the interdictor and fortifier models have increased. Also, with the raising fixed cost of the established depot, the values of the objective functions of the interdictor and fortifier models have raised. In this regard, the number of established depots in the second scenario (COVID-19 wave) is more than the first scenario (normal COVID-19 conditions).Research limitations/implicationsThe results of the current research can be useful for hospitals, governments, Disaster Relief Organization, Red Crescent, the Ministry of Health, etc. One of the limitations of the research is the lack of access to accurate information about transportation costs. Moreover, in this study, only the information of drivers and experts about transportation costs has been considered. In order to implement the presented solution approach for the real case study, high RAM and CPU hardware facilities and software facilities are required, which are the limitations of the proposed paper.Originality/valueThe main contributions of the current research are considering evolutionary games with environmental feedbacks during the COVID-19 pandemic outbreak and location, routing and allocation of the medical centers to the distribution depots during the COVID-19 outbreak. A real case study is illustrated, where the Lagrangian relaxation method is employed to solve the problem.

Proposed Model

PurposeDue to the randomness and unpredictability of many disasters, it is essential to be prepared to face difficult conditions after a disaster to reduce human casualties and meet the needs of the people. After the disaster, one of the most essential measures is to deliver relief supplies to those affected by the disaster. Therefore, this paper aims to assign demand points to the warehouses as well as routing their related relief vehicles after a disaster considering convergence in the border warehouses.Design/methodology/approachThis research proposes a multi-objective, multi-commodity and multi-period queueing-inventory-routing problem in which a queuing system has been applied to reduce the congestion in the borders of the affected zones. To show the validity of the proposed model, a small-size problem has been solved using exact methods. Moreover, to deal with the complexity of the problem, a metaheuristic algorithm has been utilized to solve the large dimensions of the problem. Finally, various sensitivity analyses have been performed to determine the effects of different parameters on the optimal response.FindingsAccording to the results, the proposed model can optimize the objective functions simultaneously, in which decision-makers can determine their priority according to the condition by using the sensitivity analysis results.Originality/valueThe focus of the research is on delivering relief items to the affected people on time and at the lowest cost, in addition to preventing long queues at the entrances to the affected areas.

PurposePier scour is one of the main causes of damage to the columns of the river bridges. It is essential to select the best method among various repair methods based on different evaluation indices. However, there is no procedure for ranking these repair methods based on their attributes. The present study seeks to set an approach for this ranking.Design/methodology/approachIn this paper, a multi-attribute decision-making (MADM) model is presented for ranking the repair techniques, in which alternatives are examined using the most important evaluation criteria. In addition, a combination of entropy and eigenvector methods has been proposed for weighting these attributes. A case study is then used to demonstrate the applicability and the validity of the method.FindingsThe execution of the model using two multi-criteria methods yielded similar results, which confirms its accuracy and precision. Moreover, the research findings showed the consistency of the objective and subjective weighting methods and the conformity of the weights obtained for the attributes from the combination of these methods to the nature of the problem.Originality/valueThe selection of the proper method for repairing the bridge columns plays an essential role in success of the bridge restoration. The proposed model introduces an approach for ranking repair methods and selecting the best one that has not been presented so far. Also, the weighing method for attributes is an innovative method for ranking restoration methods that has been proven in a case study.

Proposed Model

Purpose The purpose of this paper is to propose a model for product recommendation to improve the accuracy of recommendation based on the current search engines used in e-commerce platforms like Tmall.com. Design/methodology/approach First, the proposed model comprehensively considers price, trust and online reviews, which all represent critical factors in consumers’ purchasing decisions. Second, the model introduces the quantization methods for these criteria incorporating fuzzy theory. Third, the model uses a distance measure between two single valued neutrosophic sets based on the prioritized average operator to consolidate the influences of positive, neutral and negative comments. Finally, the model uses multi-criteria decision-making methods to integrate the influences of price, trust and online reviews on purchasing decisions to generate recommendations. Findings To demonstrate the feasibility and efficiency of the proposed model, a case study is conducted based on Tmall.com. The results of case study indicate that the recommendations of our model perform better than those of current search engines of Tmall.com. The proposed model can significantly improve the accuracy of product recommendations based on search engines. Originality/value The product recommendation method can meet the critical challenge from the search engines on e-commerce platforms. In addition, the proposed method could be used in practice to develop a new application for e-commerce platforms.

Purpose The purpose of this paper is to diagnostically explore the phenomenon of judicial corruption in Nigeria, its causative factors and generate strategies such as sonic therapeutic intervention, among others, that would facilitate an amelioration of the situation. The judiciary which is supposed to be last hope of justice for the Nigerian citizenry has been proven beyond reasonable doubt to have been infected with the virus of corruption, and therefore, an urgent call for action to rectify the situation is imperative. Design/methodology/approach The study uses a qualitative approach rooted in case study tradition. Findings The findings showed that power and testosterone, cheating proclivity, family pressure, qualitative passion and ignorance, low self-control, inordinate kleptocratic desire, unrestrained mind and sensory modalities, phenomenological mindset and identity crisis as endogenous contributive factors of judicial corruption in Nigeria. Research limitations/implications The limitation of the study stemmed from the fact that inasmuch as a perception of corruption and corruption are cultural phenomena, the study results cannot be generalizable. Practical implications The practical implication of the research is rooted in the fact that the Nigerian judiciary can gain from the study results and recommendation(s) if implemented without fear or favor for the overall renewal of the judiciary and the nation at large. Social implications The study is geared toward ameliorating the Nigerian corrupt judiciary or repositioning the judiciary on its pivotal dignity, and hence, its social implication cannot be overemphasized inasmuch as a positive social change would prevail if the study results and recommendation(s) are aligned with and implemented. Originality/value Inquiry on judicial corruption through the lens of qualitative research with Nigeria as a case study is highly understudied, and hence, this research fills the gap in the financial crime literature.

Purpose – Based on the literature devoted to family firms and the intellectual capital-based view of the firm, the purpose of this paper is not only to identify the most important human capital intangibles owned by family firms but also to show a number of indicators that can help measure them. Design/methodology/approach – A qualitative case-study-based research approach was adopted taking as reference: 25 family firms belonging to different sectors; previous works existing in the literature; and the intellectus model. Findings – The present study identifies ten intangibles associated with the human capital of family firms and shows 60 indicators that can be used to measure them. It additionally provides empirical evidence and gives examples of these intangibles through the analysis of 25 international family firms. Research limitations/implications – The difficulty in collecting all the human capital intangibles of family firms; the problems associated with the creation of accurate indicators; and those specific to the research methodology adopted. Practical implications – Identifying the human capital intangibles of family firms and their indicators can help managers become aware of their importance, and this will consequently help them improve their management. This could be an interesting starting point to value these intangibles in the balance sheet as well as to draw comparisons between family and non-family organisations. Originality/value – The framework provided by family firms sheds light on several intangibles specific to these firms – precisely for their condition as “family” firms. Those intangibles – human capital intangibles being especially highlighted in this study – provide the basis for the achievement of competitive advantages.

Purpose According to Christopher (2000), in a lot of sectors, the competition is a question of supply chain against supply chain. The winner in term of competitive advantage should be the one, who is able to obtain more than the competitor from the available resources. In strategic literature, Dyer and Singh (1998) are the first who introduced the concept of “relational competency” to explain why some companies gain their competitive advantage not directly from their internal resources but mainly because they are able better to combine external resources. Design/methodology/approach This paper is a case study. Findings The author describes the different phases and strategic decisions in the building of a real supplier eco-system. Research limitations/implications It is a sole case study. Practical implications This study is a description of a success story. Originality/value This study is a description of an external resource management in action.

PurposeA retrospective action-research case study of one branch of the University and College Union (UCU) is used to show how threshold requirements of the Act can be systematically beaten.Design/methodology/approachThe paper responds to calls for “best practice” on how trade unions may react to member voting threshold requirements of the Trade Union Act 2016 (the Act). A broader aim is to make a theoretical contribution related to trade union organising and tactics in “get the vote out” (GTVO) industrial action organising campaigns.FindingsFindings are presented as a lead organiser's first-hand account of a successful GTVO campaign contextualised in relation to theories of organising. The findings offer “best practice” for union organisers required to beat the Act's voting thresholds and also contribute to theories surrounding trade union organising tactics.Research limitations/implicationsFurther development and adaptation of the proposed model may be required when applied to larger bargaining units and different organising contexts.Practical implicationsThe findings can inform the organising practices/tactics of trade unions in relation to statutory ballots. The findings also allow Human Resource (HR) practitioners to reflect on their approach to dealing with unions capable of mounting successful GTVO campaigns.Social implicationsThe findings have the potential to collectively empower workers, via their trade unions, to defend and further their interests in a post-financial crisis context and in the shadow of the Covid-19 pandemic.Originality/valueThis is the first known empirical account of organising to exceed voting thresholds of the Act, providing practical steps for union organisers in planning for statutory ballots. Further value lies in the paper's use of a novel first-hand account of a GTVO campaign, offering a new and first, theoretical model of organising tactics to beat the Act.

PurposeThis paper proposes an integrated IT2F-FMEA model under a group decision-making setting. In risk assessment models, experts' evaluations are often aggregated beforehand, and necessary computations are performed, which in turn, may cause a loss of information and valuable individual opinions. The proposed integrated IT2F-FMEA model aims to calculate risk priority numbers from the experts' evaluations and then fuse experts' judgments using a novel integrated model.Design/methodology/approachThis paper presents a novel failure mode and effect analysis (FMEA) model by integrating the fuzzy inference system, best-worst method (BWM) and weighted aggregated sum-product assessment (WASPAS) methods under interval type-2 fuzzy (IT2F) environment. The proposed FMEA approach utilizes the Mamdani-type IT2F inference system to calculate risk priority numbers. The individual FMEA results are combined by using integrated IT2F-BWM and IT2F-WASPAS methods.FindingsThe proposed model is implemented in a real-life case study in the furniture industry. According to the case study, fifteen failure modes are considered, and the proposed integrated method is used to prioritize the failure modes.Originality/valueMamdani-type singleton IT2F inference model is employed in the FMEA. Additionally, the proposed model allows experts to construct their membership functions and fuzzy rules to capitalize on the experience and knowledge of the experts. The proposed group FMEA model aggregates experts' judgments by using IT2F-BWM and IT2F-WASPAS methods. The proposed model is implemented in a real-life case study in the furniture company.
