This paper presents a new algorithm for solving drayage problems with multisized vehicles. This new approach is based on the re-optimization concept. In this approach, real-time information about the locations of all vehicles in a fleet is used to select the optimal route for each vehicle. It also uses a heuristic algorithm based on a variable neighborhood search. It shows significant improvements over previous approaches by reducing the number of required trips. The global backlog at shipping ports has become an omnipresent issue crimping global economic activity. 

In China, COVID-19 lockdowns have shut down operations in some port-heavy provinces. The backlogs are often so large that dozens of ships anchored off the coast of California are waiting for offloading. The drayage trucking industry has become an inescapable clog in the freight supply chain. While solving drayage problems issues are not new to the industry, recent winter storms in North America have brought to light systemic problems with the drayage infrastructure. Congestion had been building for months before February, but in March, a large walkout of union truckers at Port Metro Vancouver highlighted the problem's scale. Drayage is a critical part of global supply chains, and many of the problems faced by carriers affect the entire supply chain. These challenges are often caused by shortages of drivers, containers, and parts. These shortages add to the pressures facing drayage carriers and contribute to an increase in their costs.

As a result, more efficient drayage planning can boost economic performance and improve the efficiency of intermodal transport. Specifically, this research aims to apply operation research techniques to truck movements. The primary objective is to identify the optimal solution that is best suited for a given situation. Once this is accomplished, the results will be reported back to the community. To know more about freights, visit this website at https://www.britannica.com/technology/container-ship. In addition to the challenges facing drayage operations, state politics also impact the industry. 

A pending law in California may disrupt the industry by forcing independent contractors to be treated as employees. This move would remove thousands of drivers from the road and increase the strain on ports. As a result, the industry must find new solutions for drayage operations to remain efficient and modern. Draage is an essential part of the logistics industry. It is vital to the supply chain management process in the United States. The concept of shipping in and through is a popular choice for many consumers, and drayage plays a significant role in that process. In fact, the first mile of the journey is often the most critical.
