The present research aims at investigating the impact of organizational learning on supply chain tolerance through organizational innovation. This research is practical in terms of purpose, surveying in terms of data collection and correlation type in terms of data analysis. The research population of the present paper consists of all the personnel and logistics managers of command headquarters and subsidiary units based in Tehran city, being one of the armed forces of Islamic Republic of Iran. Using Cochran formula, 130 people were chosen as sample members and in choosing samples, simple random sampling has been used. The data of this research has been collected through library and field studies using a questionnaire that its reliability has been estimated over 0.7 using Cronbach's alpha coefficient. The data analysis has been carried out using Kolmogorov-Smirnov test, Pearson's coefficient of correlation and path analysis using SPSS and LISREL software. Results show that there is a significant relationship among organizational learning, organizational innovation and supply chain tolerance, which indicate the importance of utilizing these concepts in supply chain tolerance. Finally, based on the achieved results, a number of recommendations have been put forward.

In the recent decades, with sustainable development, supply chain beneficiaries expect that environmental and social responsibility be addressed in the supply chain as well. The aim of present research is to provide a framework sustainable for the supply chain agility in the brick industry of Isfahan province. This developmental research is applied and qualitative. Using theoretical sampling, 10 experts have been selected who are familiar with the research. For coding and identifying the factors, Grounded theory has been used based on the systematic approach of Strauss and Corbin with the help of semi-structured interviews. Then, based on Grounded theory, using Maxqda software, after taking three stages of open coding, axial coding and selective coding, 11 factors were expressed for the sustainability of agile supply chain in Isfahan province. Also, the commitment of top management has been identified as a central phenomenon to achieve sustainable supply chain agility and also economical and social matters of the supply chain have been introduced as sample outcomes. This research is one of the first studies that offers a hybrid model of agility and sustainability in the brick industry and helps other related companies apply agility and sustainability to the supply chain.

Transportation as a primary part of an organization plays an important role in ensuring the proper functioning of the systems. The fact that transportation is a specialized and important task is accepted by the majority of specialists. In the previous years, there were many organizational activities in the field of transportation. As a manager's primary task is to evaluate the performance of an organization, taking this research into consideration seems to be essential to plan meticulously. One of these evaluations is meta-analysis which evaluates a research in a specific field and can be considered as a field of study. The objectives of this research are to collect and indicate components of studies carried out in the performance area of various research projects of Police Logistics in the field of transportation by identifying issues that need to be addressed, issues that do not seem to be problematic, and ones that need further research. The present study is an applied type and in terms of data collection is descriptive of survey type and the method used in this research is descriptive. The data collection instrument is based on library studies and documentation. The research population of this study consists of all the studies that have been carried out concerning transportation of Police Logistics. There is no sampling in meta-analysis, and the meta-analyzer attempts to achieve all the researches in an extensive search. The research population of this project consists of 24 researches related to the field of transportation of Police Logistics. Therefore, in this paper, the research sample will be the same as research population. In this study, a qualitative approach has been applied to meta-analysis and EXCEL software has been used to analyze the results. The addressees of many of the solutions and results in terms of administration and individual are not known. (B) The solutions presented have remained at the level of general discussion and frequent repetition, though some solutions such as outsourcing are directed and applicable in a specialized and desirable manner.

The reasons for the importance of supply chain in the recent years are the increasing pace of technology change, the globalization of commerce, tendency to outsource, greater emphasis on quality, customer benefit and satisfaction, greater emphasis on customer relationship building and retention, emphasis on relationships development with suppliers, greater emphasis on managing business processes and integrating operations, the need to build strategic links and networks, as well as developing knowledge-based and technology-based economies. The purpose of this study is to investigate the effect of supply chain participation on performance with the mediating role of value creation. This research is practical in terms of purpose and descriptive-surveying of correlation and modeling type in terms of method. The research population of this study consists of 280 managers, supervisors and experts of the organization. According to the research population being 280 employees, the required sample size is 162 people to determine the sample size using Cochran formula. The instrument for collecting data is a standard questionnaire that its reliability has been confirmed 0.951 using Cronbach's alpha. Structural equation modeling technique has been used to analyze the collected data using Smart PLS software. Results show the mediating role of value creation on the impact of supply chain participation on performance. Results also show that all components of supply chain participation have a significant effect on performance.

Transportation system brings the problem of vehicle routing that seeks optimal allocation of customers to vehicles in distribution system. There are various types of vehicle routing problems that try to provide models that are closer to the real world constraints by considering limitations such as vehicle capacity, number of demands, distance and so forth. The transportation network of Digikala Company inside and between cities is complicated based on the number of available routes, variety of means of transport and multiple distribution centers in the provincial areas. Digikala's distribution network is not only a geometric representation of the transport routes, but also represents the transport system. In this research, studying variables of shipping these goods has been considered, firstly, to identify a mathematical model for the distribution of these goods and then to examine how to solve this mathematical model, which is estimative and accurate. We solved this problem after examining and proving the model solution through approximate ways using meta-heuristic method which gives us the closest answers in NP-hard problems. Finally, while coding in small-scale Matlab software, we study the distribution model of the company and obtain the required output by proving the downward trend of the final function. The study confirms that online store companies can design, optimize, and manage complex supply chain operations at different levels with the help of Genetic Algorithm
