# Shared Logistics--Literature Review
## 4 Discussion and Research Limitations
Shared logistics can have a significant impact on the environment and society, by reducing the number of vehicles on the road, improving the use of resources, and reducing the carbon footprint. A literature review can identify the existing research on the environmental and social impact of shared logistics, and guide future research in this area. 4. The literature review in shared logistics provides valuable insights for practitioners and policymakers who can use the information to develop more effective and sustainable logistics operations. Our work makes a valuable contribution to the current knowledge as shared logistics has not been well covered in previous reviews. The review has been conducted for a specific time period and covers the most recent developments and trends in the field. However, it is important to note that any literature review is a general overview of the field and covers topics that have been analyzed in the papers. It is also worth noting that our literature review is still valuable and useful, as it can provide an up-to-date overview of the field and identify gaps in the existing knowledge. The studied works show that shared logistics can bring benefits in terms of cost savings and environmental sustainability, but challenges such as socio-technical barriers to cooperation among companies and the need for effective information management need to be addressed in order to fully realize these benefits. Additionally, some studies discussed in the text also highlight the challenges of maintaining a certain temperature throughout the supply chain, reducing waste, both in warehouses and in sales, dealing with logistics challenges in retail, and routing optimization algorithm and non-standardized logistics processes. It can be inferred that the studies and papers discussed in the review show that shared logistics can bring benefits in terms of cost savings and environmental sustainability. The studies present evidence that shared logistics can bring lower total costs, transportation costs, and inventory costs. It can also lead to lower CO2 emissions and external costs. Additionally, shared logistics can help in the distribution of goods from rural areas, valorization of by-products in circular economy, and promoting shared logistics through peer-to-peer networking practices and effective information management. The analyzed studies show that shared logistics can help in reducing waste, increasing efficiency, detecting contamination, bacteria, or other threats, and improving the distribution of goods. The detailed analysis of literature on the subject of shared logistics shows the existing gap in terms of the topics of security of assets and data sharing, concerns about safety and security issues in joint logistics operations, and most of all, ways to encourage companies to take part in shared logistics projects. Safety and security issues are also of critical importance for information sharing in a supply chain, which is referred to as the extent to which crucial and/or proprietary information is available to other members [73]. The extent of shared information can be classified as either tactical [a low level of information sharing that can satisfy basic operation needs] or strategic information (a high level of information sharing that can satisfy strategic and competitive needs) [74]. The topic for further research would also be whether it is possible for state-owned companies to participate in shared business processes, with their infrastructure and fleet base, and other assets to improve their utilization levels. More case studies of logistics collaboration to compare the quantitative and qualitative effects of joint projects with the situation of individual operational development would be worth considering. The literature review is based on a generalization, which refers to making broad statements or conclusions based on analysis. This generalization does not take into account the limitations of the data and the methods used in the analyzed studies.
