For the features of an automated storage & retrieval system (AS/RS), the simulation and analysis of the equipment utilization rate, cargo turnover speed and the optimal allocation of resources based on Flexsim software, provides a basis for decision making to improve. Simulation results show that the program can effectively Solute the bottlenecks of AS/RS; simulation method than the traditional...
Storage planning for outbound container is one of the most important operations in container terminals. It influences almost all successive operations, including storage position allocation for individual container, equipment scheduling, stowage planning and container relocation, etc. This paper studies storage space pre-allocation for outbound containers of arriving ships. Considering the complexity...
Effective use of machines and headcounts is essential in manufacturing for high return of investment from expensive resources in today's competitive business environment. It is thus crucial to establish optimal man-machine ratio to gain high resource utilization and output. In this paper, we discuss the deficiency of traditional static methods and how simulation can be applied to overcome these deficiency...
Grid technologies enable the sharing and coordinated use of diverse resources distributed all over the world. These resources are owned by different organizations having different policies and objectives, which need to be considered in making the resource allocation decisions. In such complex environments, market-based resource allocation protocols are a better alternative to the classical ones because...
An optimization method is proposed for optimal berth system expansion planning on container terminals to improve operation performance along with the growing container quantity. This planning problem is attributed to a multi-stage decision-making problem and its solution method is divided into two parts: (1) For the decision-making sequence in the long period, dynamic programming is used to determine...
