Automotive brake pad is one of the most widely used composites. Commonly, more than 10 components are applied to make these materials and due to the large number of components and interactions between them, choice, explaination of the behavior and optimization of brake friction materials are some industry's challenges. Until now, some methods have been presented to design and optimization of these materials, but due to different complexities, there is lack of practical method that could be used for explaining the tribological behavior, engineering calculation and optimization of brake friction materials. Today, formulation of the current brake pads in the industry has mainly come from trial... 

This study has added strategies to the decisions of road freight transport companies in their agent-based model. Added strategies are related to the company's supply management and in response to current and future demands. By forecasting future demand, uncertainty is to be present in this part of the demand. Firms use vehicle routing algorithms to meet existing demand, and car Sharing approaches to the second strategy. The algorithm used in the first strategy is a meta-heuristic algorithm called simulated annealing. For the second strategy, two scenarios are added to the simulation model, and in the second scenario, which is a more accurate scenario, the problem in question is defined in...
