Abstract

Purpose

Since last few years, cold chain management (CCM) has gained growing interest among practitioners, policymakers, researchers and academicians. The purpose of this paper is to provide a review focused on food cold chain management (FCCM) over the last 16 years to identify state of the art in the literature, highlight research gaps and define appropriate research questions (RQs) for future research.

Design/methodology/approach

The paper analyzes the content of 89 research articles published on the topic of food cold chain (FCC) from 2001 to 2016 within different journals. The Scopus and Web of Science databases were taken into consideration to shortlist research articles. Henceforth, the authors scrutinized the FCC industry to offer some effective strategies to tackle the chain complexities. The authors also draw interwoven between FCC infrastructure, integration, stakeholders’ interest, value addition, partners’ performance and overall food cold chain performance (FCCP) into a conceptual framework.

Findings

This paper identifies four research gaps in the literature of FCC concerning the most popular approaches used for the FCCP measurement, the performance measurement metrics, the factors which negatively affect the FCCP and the main sustainability issues in FCC.

Originality/value

This study identifies RQs which represent possible areas of investigation to improve the body of the FCCP evaluation and management. Furthermore, the FCC practitioners, food authorities and researchers might find this review useful, as it draws a clear picture of research in the respective domain.

Abstract

Purpose

The purpose of this paper is to develop a data envelopment analysis (DEA) technique that simultaneously measures efficiency and effectiveness to provide a comprehensive appraisal of the productivity. Additionally, an algorithm is recommended to determine targets that are used for measuring effectiveness.

Design/methodology/approach

In this paper, for measuring productivity, a new methodology based on non-parametric mathematical DEA technique was presented. The proposed procedure is able to compute the efficiency input effectiveness, and output effectiveness, simultaneously.

Findings

By comparing with previous models, the authors’ proposed integrated model generates more detailed results and has more discriminating power.

Originality/value

To the best of the authors knowledge, there is not any study in which a non-parametric mathematical approach measures productivity through simultaneous combining of the effectiveness, including input effectiveness, and output effectiveness, and the efficiency.

Abstract

Purpose

The pressure of globalization has raised social concerns related to the protection of the environment, forced companies to use sustainability as a strategic weapon to fulfill the legal obligations and achieve overall competitiveness. It is reported that small- and medium-sized enterprises (SMEs) are globally responsible for approximately 70 percent of the industrial pollution, justifying urgent attention to the operations of these businesses. The purpose of this paper is to analyze the impact of sustainability orientation (SO) and supply chain (SC) integration implemented by SMEs on their sustainable procurement (SP) and design. Moreover, this study examines how SMEs’ SP and design affect their environmental and cost performance (CP).

Design/methodology/approach

The authors develop a comprehensive model to test the relationships among SC, SC integration, SP, sustainable design (SD), environmental performance (EP) and CP at the SMEs level. The authors investigate the relationships of the mentoned factors by a data set that is collected from 358 Indian manufacturing SMEs.

Findings

The results indicate that in the SMEs’ context: SO positively influences both SP and SD; external integration positively affects SP; internal integration positively affects SD; SP positively influences EP and has not impact on CP; and SD positively influences both EP and CP.

Originality/value

This study provides a broad view of the relation between driving factors that may direct SMEs toward a better sustainability performance and offers practical managerial insights into these important business entities.

Abstract

Purpose

The purpose of this paper is to develop a model based on data envelopment analysis (DEA) and program evaluation and review technique/critical path method (PERT/CPM) for determining prospective benchmarks.

Design/methodology/approach

The idea of determining prospective benchmark is needed for developing a model for future planning where inputs and outputs of systems are influenced by external factors such as economic conditions, demographic changes, and other socio-economic factors. In this paper, the PERT/CPM method estimates prospective inputs and outputs. On the other hand, in particular systems some measures play the role of both input and output. Such factors in DEA literature are called dual-role factors. This paper integrates PERT/CPM technique and the DEA.

Findings

The results of the proposed model depict that a present benchmark may not be a benchmark in future. A numerical example validates the proposed model.

Originality/value

This paper, for the first time, applies the PERT/CPM technique to incorporate the ideas for identifying prospective benchmarks. Moreover, the proposed model is an alternative solution for classifying inputs and outputs in DEA. Also, the proposed model is utilized in benchmarking green supply chain management.

Abstract

Purpose

The purpose of this paper is to introduce an innovative data envelopment analysis (DEA) model entitled “Non‐binary Arithmetic Operator Dual‐role” (NAOD) under free disposability assumption for selecting the refrigerated containers in cold chain management (CCM).

Design/methodology/approach

In classical DEA models, it is assumed that all of input and output variables play a certain role. However, in some cases, some variables play both input and output roles, simultaneously. These variables in DEA are called “dual‐role” factors. This study introduces a new approach to deal with these factors in the process of evaluating a set of homogeneous refrigerated containers, which is based on Free Disposal Hull (FDH) (one of the DEA models). However, in previous dual‐role models, this variable is considered as a binary variable. In this paper, a partial role for dual‐role factors is considered.

Findings

The main findings of this paper are: for the first time, the NAOD model is developed for the container selection problem in the context of CCM and the dual‐role factors are considered for the container selection problem. The NAOD model determines partial role of dual‐role factors and can consider multiple dual‐role factors. For the first time, the container selection problem is solved by an FDH model. The result of NAOD model is validated by genetic algorithm.

Originality/value

The paper makes a sufficient contribution to the practice of operations research. It is the first study which applies advanced DEA models for selecting the containers in the context of the CCM. To the best of the authors' knowledge, there is no other reference that deals with container selection in the context of CCM in the presence of dual‐role factors.

Abstract

Purpose

The purpose of this paper is to present a new approach for the optimal design of protective current transformers (CTs). The proposed technique is applied to the design of typical CTs and results are compared with traditional CT design method and genetic algorithm optimization algorithm.

Design/methodology/approach

The aim of CT design is to make current measurements more accurately, particularly for the high fault currents which arise in short circuits, and more efficient CT in terms of both size and cost. The present work formulates these objectives as an optimization problem to be solved by particle swarm optimization.

Findings

Simulation results demonstrate the effectiveness of this technique in optimizing the CT design parameters. The designed CTs have smaller measurement errors compared to standard values and respond well to high fault currents. Manufacturing costs have also been reduced.

Originality/value

In addition to improved efficiency, the benefits of this method are its treatment of CT design in terms of an equivalent circuit and design parameters. The proposed algorithm also extends the linear operation area of the CT and guarantees its good response to high fault currents that may occur in power systems.

Abstract

Purpose

During hospitalization, children are faced with physical disorders and many psychological challenges. One important factor affecting children is the environmental design of the hospital. The inappropriate design of hospitals may contribute to an increase in fear, anxiety and behavioral disorders. The purpose of this study is to use children’s perspectives to evaluate the importance and impact of effective environmental factors to generate children’s hospital design guidelines.

Design/methodology/approach

In this study, children’s desired atmosphere during treatment was examined via 16 drawings and 24 interviews from children at a children’s hospital in Iran.

Findings

The encoding of information extracted environmental components such as window view, color, hobby, playing, decorations, family presence, structure of hospital, presence of nurse, furniture, water features, light and green space. The results indicate that children prefer a hospital environment that provides entertainment facilities while also offering design features such as the presence of light, colorful decorations, the existence of green spaces and conditions suitable for their families to be present.

Research limitations/implications

Depending on the location and their living conditions, the children’s prioritization can be different in any society. In addition, the data of this research was descriptive; thus, the conclusions must be considered tentative.

Originality/value

A number of studies focus on the needs of populations in developed countries. This topic has not been investigated in a major way via professionals in non-western countries such as Iran. Thus, the context of this study and present findings can be deemed unique.

Abstract

Purpose

The purpose of this paper is to develop a multi-item economic production quantity (EPQ) strategy under grey environment and space constraint. Since the “demand” cannot be predicted with certainty, it is assumed that data behave under grey environment and compare the proposed inventory model with other studies using crisp or fuzzy environments.

Design/methodology/approach

This paper is to optimise the cycle time and total cost of the multi-item EPQ inventory model. For this purpose, the Lagrangian coefficient is used to solve the constrained optimisation problem. The grey relational analysis approach and grey data are applied in developing the EPQ inventory model.

Findings

The results are compared with the analysis using crisp and fuzzy data. Sensitivity analysis is done to illustrate the effect of parameter variations on the optimal solution. The results of the study demonstrate that crisp data outperform the other two data in all scales problems in terms of cycle time and cost; grey data perform better in all scales problems than fuzzy data.

Originality/value

The contribution of this research is the use of grey data in developing the EPQ inventory model with space constraint.

Abstract

Purpose

The paper aims to analyze the impact of cyber attacks on stock returns of companies operating in the hospitality sector. The fast development of information and communication technologies has been posited as both an opportunity and a challenge to the United Nations Global Sustainable Development Goals. Digital technologies are significant tools for sustainable development, but if they are not addressed appropriately, they can potentially hinder the progress toward sustainability. Among negative impacts, it is necessary to consider cyber risk, a major concern today, in particular for industries which work with sensitive data, such as tourism businesses. Hospitality businesses have to adequately manage cyber insecurity and digital privacy issues, to prevent losses and contribute to socioeconomic sustainable growth.

Design/methodology/approach

Using event-study methodology, the paper provides empirical evidence on the effect of announcements of 170 information security breaches on the market value of firms operating in the hospitality sector in the past five years.

Findings

The study focuses on identifying potential threats of cyber attacks for the economic value of listed companies. The authors find that negative market returns occur following announcements of cyber attacks suffered by hospitality companies. Adequate investments in technology for cyber security and staff training are relevant in the hospitality sector to reduce cyber risk.

Originality/value

The paper contributes to identifying potential threats of cyber attacks for the economic value of listed companies operating in the hospitality sector. The analysis is carried out by collecting an original sample of global cyber attacks from newspaper announcements sourced from the LexisNexis database.
