Location-Routing Problem (LRP) is a strategic supply chain design problem aimed at meeting customer demands. LRPs involve selecting one or more depot sites from a set of potential locations and determining the best routes to connect them to demand points. With the rising awareness about the environmental impacts of transportation over the past years, the use of green logistics to mitigate these impacts has become increasingly important. To compensate for a gap in the literature, this paper presents a robust bi-objective mixed-integer linear programming (MILP) model for the green capacitated location-routing problem (G-CLRP) with demand uncertainty and the possibility of failure in depots and routes. The final result of this Robust Multi-Objective Model is to set up the depots and select the routes that offer the highest reliability (Maximizing network service) while imposing the lowest cost and environmental pollution. A Nondominated Sorting Genetic Algorithm (NSGA-II) is used to solve the large-sized instances of the modeled problem. The paper also provides a numerical analysis and a sensitivity analysis of the solutions of the model.

Vast changes and increase in global events have caused a crisis among public and private organizations. If organizations cannot manage the created crisis, they might be damaged widely. Lack of readiness and inappropriate management of crisis might even lead to the destruction of the organizations. Therefore, crisis management prepares the conditions to reduce the destructive effects caused by crisis. Having crisis management in organization requires expansion of various indicators that implementing and operating each of these indicators increase the organization capability to confront with crisis. In the present study, identifying and ranking indicators of crisis management have been considered. The primary results indicate that 12 indexes have been identified for crisis management. In addition, the results, according to experts’ ideas, led to elimination of two indicators and 10 indexes were finalized. Then, using VIKOR method, the final indicators were ranked. The results of ranking indicated that three indexes of appropriate management style, management of human resource and responding speed, as well as crisis confrontation regarding cost, time were at the best to be implemented in the organization.

This research presents an empirical investigation to study the relationship between communication models and crisis management in city of Tehran municipal firefighting department. The study develops a questionnaire with 21 questions, distributes it among 400 people who worked for firefighting department associated with municipality of Tehran, Iran. Crobnach alphas for all components of the survey were well above the minimum acceptable level of 0.7. Kolmogorov–Smirnov test has indicated that all components of the survey were normally distributed. Using a t-student test, the study determined that there were meaningful relationships between communication models and crisis management (sig: 0.000), between vertical model and crisis management (sig: 0.000), between ring model and crisis management (sig: 0.000), between star model and crisis management (sig: 0.000) and between Y model and crisis management (sig: 0.000) in Tehran municipal fire department.

The aim of this study is to identify important factors influencing organizational readiness to deal with the crisis in business organizations. The study designs a questionnaire in Likert scale and distributes it among some experts who work for Mapna company in Iran. The study uses the method developed by Mitroff (2005) [Mitroff, I. I. (2005). Why some companies emerge stronger and better from a crisis: 7 essential lessons for surviving disaster. AMACOM Div American Mgmt Assn.], which investigates the effects of four factors including job satisfaction, increase in income, cost reduction and change in strategies on crisis management. Using Pearson correlation ratio, the study has confirmed a positive and meaningful relationship between crisis management and three factors including increase in income, cost reduction and change in strategies. However, the study did not find any evidence to support the relationship between job satisfaction and crisis management.

This paper presents an empirical investigation on redesigning Tehran Arge square based on principles of sustainable urban development and crises management. The proposed study performs the study based on three perspectives including quality improvement, sustainability and crisis management. In terms of city quality improvement, the study detects six factors including social interaction, cleanliness, attractiveness, comfort, vitality and security. In terms of sustainability, the study discusses three areas including different types of construction, high density and use of clean energy in buildings. Finally, in terms of crisis management, the study discusses five perspectives including wide open spaces, appropriate coverage of the floor space, appropriate performance, strength of neighboring buildings and suitable materials.

This study investigates whether enhancing organizational agility and mental health of staff could increase strategic readiness for crises or not. In this study, descriptive statistics is used to present demographic data of the research, and P-Test is employed for analyzing the data. In addition, to examine research hypotheses, correlation coefficients and descriptive statistics are implemented. Finally, to rank the variables and indicators of the research, Friedman test and for comparison of indicators and components of the research, nonparametric Kruskal-Wallis test are used. The proposed study designs a questionnaire and The questionnaire and distributes it among some nurses in obstetrics and anesthesiology department and among supervisors. Cronbach & apos; s alpha is also employed for determining the reliability in this study. The results indicate that working conditions as well as employees’ mental health are in good conditions, the employees with higher levels of mental health have higher readiness to deal with potential crises, and the relationship between agility of hospitals and their strategic readiness for dealing with crises is confirmed.

The management of procurement and distribution is one of the most important branches of the crisis management and events that, has great importance in the field of management. In this paper, we perform an empirical study to investigate important factors on emergency logistic emergency preparation distribution management among people who worked for governorship, hygiene and treatment, Red Crescent, electricity, water and sewage and transportation of central province of Ilam in west part of Iran. The survey distributed a questionnaire among some people and examined six hypotheses. The results of our survey indicate that employees who worked for these organizations maintained high levels of skills; they were able to access what they needed in their organization. In addition, the survey indicates that the access to the necessary information in their organizations; they are able to take care of their documentations. They could also execute their jobs based on good schedules and accomplished their tasks, properly. They survey also performed a multi-criteria decision making approach using AHP to prioritize important activities to improve logistic operations. The results indicate that having a good database is number one priority with relative weight of 0.51, followed by appropriate operating planning with relative weight of 0.295. Supply control came on the third position with relative weight of 0.134 and finally task assignment came as the last priority with relative weight of 0.061.
