Increase the Efficiency Rate of Container Loading and Unloading Using Six Sigma Method

ABSTRACT: The present research has been conducted to investigate the efficiency Rate of container loading and unloading in the studied port , in three dimensions; ships in port quay and loading and unloading operations using Six Sigma method. Six Sigma methodology is a method for measurement of performance deviations using statistics concepts. This method analyzes performance measurement and recommends improvement solutions for organization processes. SixSigma gives guideline to managers for reduction of errors, wastes saving and increasing competitiveness. In this research, container cargo loading and discharging operations BIK evaluated by DMAIC methodology. First step of DMAIC is problem definition in which loading and unloading ratio identified as CTQ of process. Second step is measurement of sigma level of loading and discharging process that is calculated 2.5sigma. On third step, root causes of delays in loading and discharging operations are identified by FMEA method. Defect of vertical quay transportation equipment (576)technical malfunctionanddefect ofhorizontalquay transportation equipment (576)unpreparedness of port external factors includingowners(480)inelasticityofcontaineryard(448) are identified to be the root causes by FMEA method. In forth step of DMAIC, the optimum inputs arrangement of discharging operation is studied by Taguchi DOE method. Result of this method is that vessels with container shipment and more than 900 TEU tonnage cargos that berthed at 8 – 16 oʹclock have the best discharge performance.
