CONTAINER STACKING REVENUE MANAGEMENT SYSTEM: A FUZZY-BASEDSTRATEGY FOR VALPARAISO PORT

摘要

This article presents an intelligent system for container stacking based on fuzzy logic. The method establishes a defined criterion foraccepting or rejecting in real time an entry request to the stacking areas of the port in Valparaiso, Chile. A case study based on expertknowledge illustrates the proposed method with real data. First, the optimum solution is determined for a problem of maximization of entries,based on historical records from the traffic and information center of Valparaiso Port. Second, this solution is used to establish a strategy formaking ?the best possible decisions.? The combination of the optimization and the fuzzy results (which consider the type of cargo, prices,and capacity) is performed at two levels. First, the optimization results are used as feed for the fuzzy system to determinate a ratio of futureacceptances. Second, the optimization results are compared to the fuzzy system results in order to estimate a parameter to establish theminimal percentage value for accepting a request. As a result, a proper use of the stacking area is achieved, which results in an increase ofprofits and revenue management.
