Purpose – The purpose of this paper is to propose a model for relief inventory ordering considering declining demand and realized shortage (RS) costs. This study is motivated by the overflow of unsolicited items in affected areas, which hinder the urgent relief flow. Design/methodology/approach – This study proposes a dynamic programing model reflecting the change of demand and urgency during relief operations. A solution algorithm for finding a replenishing point of relief is also introduced here. Findings – Relief ordering policy based on the RS cost increases the service level (in terms of time). The service level is dependent on the deterioration rate. Research limitations/implications – Deterioration is not applicable for all relief items. Therefore, the proposed model is applicable for certain relief items. Additionally, computation of temporal urgency is not included. Practical implications – The study outcomes can be invaluable for resource planning. The model shows a gradual decrease of ordering quantity and a gradual increase of cycle length. This observation can be utilized for resource (e.g. truck) planning and fewer truck can be used in later stages of relief operations. Originality/value – This study introduces temporal urgency for disaster logistics (DL) and proposes a relief inventory policy by incorporating temporal urgency. This model highlights the importance of considering declining demand for DL.

Purpose – The purpose of this paper is to propose a model to guide organizations according to the relative importance of customer's satisfaction about six quality service dimensions: reliability, empathy, assurance, tangibility, responsiveness (Parasuraman et al., 1985) and price. Design/methodology/approach – The present study uses SERVPERF customer requirements and weights of ELECTRE TRI multicriteria method to provide guidance on an appropriated action plan. Subsequently, it was demonstrated how the proposed model applied to the Inn. Findings – SERVPERF is based on the subjective and cognitive perception of customer's service analyses. ELECTRE TRI decreases the deviation of subjectivity and develops manager's energy flow, focussed on enterprise resources. Research limitations/implications – Measuring quality is hard work and usually the customer perceptions are not well understood, because it changes many times. In addition SERVPERF and ELECTRE TRI weights do not order the quality importance. Practical implications – Together, SERVPERF and ELECTRE TRI allow managers to prioritize the service level desired by the customer. Originality/value – The importance of this analysis follows the competitiveness approach: productivity, quality and flexibility (Boljwin and Kumpe, 1990). The paper develops an approach to lead organizational quality performance based on the customer view. It provides a sustainable competitive advantage.

Purpose The purpose of this paper is to explore how culture, including traditions and social structures, can influence resilience and how culturally sensitive relief operations can put affected people and their context at the core of any interventions. Design/methodology/approach A case study of the Mt Sinabung volcano area in Indonesia was undertaken. As part of the case study, an analysis of interventions was conducted, which was complemented by semi-structured interviews with Karo cultural experts and humanitarian organisations. Findings Culture influences the manner in which the Karo people react to volcano eruptions with varying implications for recovery. In addition, relief organisations which understand people’s actions through a cultural lens have better managed to tailor programs with long-term impact, thereby avoiding aid dependency. Practical implications Practical examples of disaster management activities that adequately account for the beneficiaries’ way of living prior to the eruptions are provided. Aid actors are provided with guidance concerning how to better tailor their activities in line with a cultural lens. Originality/value The study provides empirical grounding for claims concerning the role of culture in planning interventions in Indonesia and other similar contexts.

Purpose This paper aims to propose an innovative blockchain-based system enabling implementation of a bond-pays model in credit rating industry. Issuer-pays model has led to conflict of interest resulting in rating shopping and inflation. Alternative business models have their own problems, e.g. investor-pays model suffers from “free rider” and public dissemination challenges, whereas government-controlled business models can lead to market distortion. Bond-pays model has been difficult to implement owing to operational difficulties in managing co-ordination amongst multiple entities involved, often with conflicting goals. Blockchain technology enables inter-organizational systems that foster trust amongst non-trusting entities, facilitating business functions such as credit rating to be carried out. Design/methodology/approach This paper outlines current processes in credit rating business that has led to repeated rating failures and proposes a new set of processes, leveraging capabilities of blockchain technology to enable implementation of an arms-length bond-pays model. Findings A proof-of-concept system, namely, rating chain has been designed to implement a small part of the proposed model to establish technical feasibility in a blockchain environment. Practical implications A fully functional blockchain-based system on bond-pays business model, if built and adopted, could impact how credit rating market functions currently and could contribute to a reduction in rating-related challenges. Originality/value The proposal to adopt blockchain technologies in implementing a bond-pays model in credit rating industry is a novel contribution.

Purpose The purpose of this paper is to propose a framework for data analytics where everything is grey in nature and the associated uncertainty is considered as an essential part in data collection, profiling, imputation, analysis and decision making. Design/methodology/approach A comparative study is conducted between the available uncertainty models and the feasibility of grey systems is highlighted. Furthermore, a general framework for the integration of grey systems and grey sets into data analytics is proposed. Findings Grey systems and grey sets are useful not only for small data, but also big data as well. It is complementary to other models and can play a significant role in data analytics. Research limitations/implications The proposed framework brings a radical change in data analytics. It may bring a fundamental change in our way to deal with uncertainties. Practical implications The proposed model has the potential to avoid the mistake from a misleading data imputation. Social implications The proposed model takes the philosophy of grey systems in recognising the limitation of our knowledge which has significant implications in our way to deal with our social life and relations. Originality/value This is the first time that the whole data analytics is considered from the point of view of grey systems.

PurposeThis paper aims to propose a unified framework for understanding the development and distribution of value within and from enterprise and entrepreneurship education. In doing so, the authors trace the origins of value creation pedagogy back 100 years and reconnect this lost literature to contemporary thinking as to what constitutes value creation pedagogy.Design/methodology/approachThis conceptual paper identifies specific temporal-specific problems with current thinking in enterprise and entrepreneurship education vis-à-vis who gains the value from value creation pedagogies. To address this identified anomaly, the authors seek to develop a spectrum of value-creating activities/processes applicable to enterprise and entrepreneurship education. The underlying aim of this approach is to provide clarity around who specifically benefits from value creation pedagogies, how and when.FindingsIn developing a spectrum of value-creating activities/processes applicable to enterprise and entrepreneurship education, the authors have successfully located all major forms of value creation pedagogies in an iterative manner that caters to the authentic development of value for oneself and others. The proposed model assumes that the creation of authentic value for others should be preceded by the development of specific capabilities in the value creators.Practical implicationsThere are important implications that arise for all enterprise and entrepreneurship educators in the discussions presented here. Most importantly, value creation pedagogies should be fueled by the ongoing development of purpose, agency and capability via cultivated reflection.Originality/valueThis paper broadens the notion of what constitutes value creation pedagogy in enterprise and entrepreneurship education. In doing so, the authors elevate the importance of student creative competency development over value creation.

Case Based

PurposeThis research aims to explore the enabling and constraining effects of enterprise resource planning (ERP) systems and speculate on how these can be linked to the four generic roles of operations management (OM) proposed by Slack et al.Design/methodology/approachThis research understands ERP as boundary objects characterised by modularity, abstraction, accommodation, and standardization. An in‐depth cross‐disciplinary literature review and role synthesis is conducted.FindingsFour enabling and three constraining effects of ERP are deduced from existing literature. ERP and OM are linked conceptually. Based on the identified effects of ERP, the paper speculates on the managerial tasks of the production and operations manager (POM) in an ERP environment and lists a set of central concerns of potential relevance to POM and to future research.Research limitations/implicationsThe identified roles of ERP and their implications could be empirically tested using case based and survey research.Practical implicationsThe results provide insights into how ERP has multiple and parallel roles, and how these roles are relevant to the function of OM. Such knowledge is valuable for practicing POMs in managing the implementation and design of ERP to support the different domains of OM.Originality/valueCurrent studies of the effects of ERP and their link to the practice of OM tend to focus on one or a few roles of the emerging system. Such studies do not properly take into account the modularised and pluralistic nature of ERP. This research provides a platform from where future research on the effects, managerial dilemmas and implications of ERP can be reconciled across research communities.

Purpose The purchasing of services is a significantly under-researched area. The purpose of this study is to suggest a conceptual model of service sourcing relationships, including the post-contract phase. Design/methodology/approach A qualitative methodology involving two longitudinal case studies that were analyzed with a grounded theory approach to build a conceptual model was applied. Findings The proposed model consists of a core process that is termed “business streamlining” and denotes the process by which four interrelated dimensions are managed to making the business processes of the buying organization simpler and more effective and/or productive. Research limitations/implications Although the research methodology is qualitative and does not allow statistical generalization, the study does provide valuable insights into the management of the service sourcing process. Practical implications The model proposed in this study can be utilized by managers to impose a useful conceptual structure on otherwise fluid and intangible processes, which makes them easier to analyze and facilitates strategic corporate decision-making. Originality/value The paper proposes a model that grasps the dynamics and reality of service (out-) sourcing relationships, including the ongoing relationship management process.
