Alongside with industrialization of societies, supply chains increasingly and negatively affect the environment and social issues through wasteful consumption of natural resources and creating ecological pollution. This paper aimed at examining how sustainability and innovation can be discussed at the level of the supply chain. In doing so, a systematic literature review was carried out with a special focus on papers published by Scopus from 2015 up to 2018. This period of time was selected due to the prior research covering the time span of 1996 to 2014. The descriptive aspects of the published papers were first examined. Then, the contextual analysis was accomplished. The analysis showed an upward trend of literature in numerical terms and a wider spread of sustainability and innovations. Additionally, the study highlighted further areas of research that are deserving of attention. These areas include analysis of specific research activities in the less developed countries and more attention on the social and environmental dimension of sustainability. Finally, a framework is developed which could constitute the basis for further developments and research on this issue.

The present study introduces a bi-objective optimization model for emergency medical service location to make balance between accessibility and coverage target functions. The recommended model considers location strategic decisions and allocation tactical decisions. Moreover, in contrary to most models which consider fixed capacity for potential points of facilities that cause some limitations in using such models; this article introduces a modular planning problem that is capable of considering several possible capacities for facilities. The new model considers the allocation of demands out of coverage zone for optimal location of ambulances. Applying of this model to the case study that its data obtained from emergency center of Kerman City was studied. Finally, the numerical results obtained from model deployment and sensitivity analysis tests were presented in addition to managerial points.

Resilience is one of the most important factors against different types of disruption to maintain organizations survival and their supply chain. In the meantime, firms with high resilience, remain stable in supply chain disruption situation. Therefore, this study is proposed to investigate the factors affecting firms resilience to maintain their optimal status in the disruption situations.
This study in terms of objective, is an applied one, and is a descriptive-analytic research in terms of type and nature of research, and it is a sectional survey in terms of method. The required statistical data were collected by the use of simple random sampling method and distributing questionnaires among 180 managers of Alborz industrial town`s. In order to analyze the data we used the Structural Equation Modeling Smart Pls and SPSS software.
Outcomes indicated that in low disruption situation, involved factors in supply chain disruption orientation, knowledge management, human resources strategy and dynamic competitiveness are affected by the firms resilience. However, in these circumstances, the resources reconfiguration and organizational innovations have no mediating role. Also, in high disruption situation, resources reconfiguration, knowledge management and dynamic competitiveness have a significant and direct effect on firms resilience. On the other hand, resources reconfiguration has a significant mediating effect on the relationship between the supply chain disruption orientation and firms resilience. But, organizational innovation has no mediator effect on the relationship between knowledge management and firms resilience.
The conceptual model of study is new and based on investigated which we did in several studies.

The automotive industry is one of the country's most important industries, and in fact, it is economic stimulant of many other industries. The purpose of this study is to identify and investigate the impact of supply chain’s risk factors on financial performance of IranKhodro Khorasan Company, identifying the major and important supply chain risks, required questionnaires have been prepared by relying on the literature of the case and involving the valuable comments of Iran Khodro Khorasan's supply chain specialists and according to that the relative importance and ranking of each risk in Iran Khodro Khorasan Co. is determined.(using MCDM techniques including AHP techniques for weighting the measurements craiterian, VIKOR and TOPSIS techniques were used to ranking the risks.)
Considering the fact that in this research the specialists from all party of Iran Khodro Khorasan’s supply chain of have been consulted, the results of this study provide the possibility for senior company managers to have better capabilities in identifying and dealing with risks specially with unexpected risks and, by effective coping and timely response, eliminates or minimizes the negative and destructive effects of risks, and can also help to make strategic decisions and develop operational plans to deal with risks.
According to the results of this study the risks of: inappropriate material planning, inventory updating failure, truck drivers strikes, delayed delivery of raw materials and parts from suppliers, and financial problems,are as the most important and influential risks of Iran Khodro supply chain considering the effection on financial performance.

In the recent decades, tourism industry has considered as the most important industry and has grown dramatically therefore, the share of international tourism in the global economic activities are continuously increasing. Today, the tourism industry is too important in the economic and social development of a country thus economists call it invisible exports. Ecotourism is a type of tourism in which tourists travel to visit and enjoy the world's undisturbed natural areas and watch plants, birds, fish, and other animals.The objectives of ecotourism are educating and making the ecotourists ready to protect and respect ecosystems and natural resources and to become familiar with diverse cultures, beliefs and human rights. Also ecotourism plays a major role in the economic and political development of local communities. According to the importance of ecotourism, this study presents a mathematical model for ecotourism supply chain. The proposed model is single-objective one which maximizing the chain’s profit. Due to the demand uncertainty, the fuzzy method is used to deal with uncertainty. An applicable numerical example was also presented and the mathematical model was solved by Lingo software and the results were examined.

Increased competition in the current era, Environmental laws and regulations and Economic benefits Due respect to the field of supply chain sustainability Caused the companies will pay special attention to the Green supply chain management and reverse logistics. Although the companies are increasingly under pressure to consider green and reverse logistics activities in their supply chains, but because there are obstacles in the use and development of reverse logistics, its implementation has been limited. Therefore, Identifying strategies and solutions to tackle these barriers is essential. In this study, addition to identify barriers of implementing reverse logistics, Reverse logistics strategies to overcome barriers were also identified and prioritized. At first, by review of accomplished researches in this area, a list of barriers and criteria were identified. Then, by using the Fuzzy Delphi method, identification Criteria were mitigation and finalized. Then by using of SWARA method Criteria and sub criteria were weighted. Also a list of solution in order to tackle with reverse logistics implementation barriers were identified from the literature. In the next step, using the WASPAS methods, identified solution were prioritized. The results showed that Twelfth solution (create, develop and invest in reverse logistics technology) was selected as the most important solution.
