Abstract
This talk will focus on two topics: (1) Design and performance analysis of production lines and (2) Vessel arrival processes at marine ports.
Analysis of production lines has been a challenge for decades due to complexities in their exact analysis. In Part 1, a simple, approximate and accurate decomposition principle will be presented to estimate throughput and average WIP levels in production lines. The approach segregates the line into several subsystems that are easier to analyze and an iterative algorithm aggregates them to produce results for the production line. The approach will be extended to design supply chains. This part will conclude with some numerical results.
Marine ports are an important component of the world’s economy and present many challenges in terms of logistics and security. For instance, over 95% of the cargo that arrives at the US enters the country through the marine ports. In Part 2, the stochastic processes underlying vessel inter arrival times at marine ports will be presented. These inter arrival times are correlated and present challenges in modeling for logistics purposes. A unified model will be proposed and numerical implications will be discussed.
