Abstract
Purpose
This study aims to explore and analyzes the risk factors in container shipping and logistics services using a dual perspective. The authors gather data not only from logistics service companies but also from their most important customers.
Design/methodology/approach
In this research, the authors used case study methodology (interviews and surveys) to examine risk factors that are related to one another within the interaction between logistics service companies and their customers in the emerging markets of the Mediterranean region (Turkey, Algeria, Tunisia and Libya).
Findings
The findings show the most important risk factors and compare them using a dual perspective. Customers identify additional risks and estimate their consequences as wider. Interestingly, oil price change plays a dual role because a price increase could be beneficial to the region; at the same time, however, the competitiveness of shipping would decrease. In both response groups, risk likelihood and risk consequence have a positive and statistically significant correlation.
Research limitations/implications
The findings of the study are limited to one shipping/logistics service company. On a global scale, the company is medium-sized; however, in terms of Northern Europe, it is an important player. Extending its service portfolio to the Mediterranean region is an important step.
Practical implications
In emerging markets, risks go hand in hand with profitability, and companies need to apply extensive risk analysis and mitigation strategies to survive.
Social implications
The southern Mediterranean region is showing some signs of economy recovery. Efficient, robust supply chains are in demand to support sustainable growth.
Originality/value
Using a case study approach in supply chain risk management in shipping is rather rare; this work is ground-breaking in that it uses dual perspective in the analysis.

Abstract
Purpose
In a multistage process, the final quality in the last stage not only depends on the quality of the task performed in that stage but is also dependent on the quality of the products and services in intermediate stages as well as the design parameters in each stage. One of the most efficient statistical approaches used to model the multistage problems is the response surface method (RSM). However, it is necessary to optimize each response in all stages so to achieve the best solution for the whole problem. Robust optimization can produce very accurate solutions in this case.
Design/methodology/approach
In order to model a multistage problem, the RSM is often used by the researchers. A classical approach to estimate response surfaces is the ordinary least squares (OLS) method. However, this method is very sensitive to outliers. To overcome this drawback, some robust estimation methods have been presented in the literature. In optimization phase, the global criterion (GC) method is used to optimize the response surfaces estimated by the robust approach in a multistage problem.
Findings
The results of a numerical study show that our proposed robust optimization approach, considering both the sum of square error (SSE) index in model estimation and also GC index in optimization phase, will perform better than the classical full information maximum likelihood (FIML) estimation method.
Originality/value
To the best of the authors’ knowledge, there are few papers focusing on quality-oriented designs in the multistage problem by means of RSM. Development of robust approaches for the response surface estimation and also optimization of the estimated response surfaces are the main novelties in this study. The proposed approach will produce more robust and accurate solutions for multistage problems rather than classical approaches.

This paper deals with the combined management and design of a sustainable pharmaceutical supply chain network with considering recycling.
Abstract
Purpose
This paper deals with the combined management and design of a sustainable pharmaceutical supply chain network with considering recycling.
Design/methodology/approach
This paper first utilizes the analytical hierarchy process to select and rank green manufacturers. Second, the authors proposed a multi-objective nonlinear mathematical model to design a sustainable pharmaceutical supply chain network. The proposed model has been linearized and solved using the LP-metric method using GAMS software.
Findings
A real case study has been conducted in Iran. The results show that environmental and social issues can be improved while minimizing total costs.
Originality/value
Given the criticality and importance of drugs in human health and the importance of recycling in today's world, proper management and design of a sustainable drug supply chain are necessary. This study pays special attention to environmental issues by utilizing multi-criteria decision approaches and customer satisfaction.

Abstract
Purpose
The purpose of this study is to introduce and evaluate the effect of critical success factors (CSF) in rescue operations in burning buildings by calculating the partial least squares structural equation modeling of PLS-SEM.
Design/methodology/approach
To do this, success criteria (SC) and CSF in the literature, which are related to the topic, articles, standards and relevant books, will be identified and then evaluated through the extended PLS-SEM model.
Findings
The results show that technological factors, awareness, resources and safety play an effective role in successful performance management in fire accidents.
Research limitations/implications
Appropriate use of these factors will promote incident management and decrease casualties and financial loss in the event of accidents.
Originality/value
Fire-fighting is of great importance, especially in tall and complex buildings. In recent years, extended studies have been carried out regarding fire accident management in terms of CSFs in the category of rescue and firefighting. However, attention has not been paid to the relation and severity of impact between SC and CSF by researchers in addition to the identification of the most important criteria during rescue operations.
