Abstract

Transportation and distribution are two things that are closely related to logistics problems However, on the other hand this activity can sometimes damage the environment. Emissions from fuels used in transportation and distribution activities accounted for 29.4% of the total costs incurred by the organization in their activities. From this issue many organizations finally make environmentally friendly logistics as priority in their activities, where the goal of minimizing distribution costs and maintaining sustainability of environments. Some factors that can be improved are: determination of the location depot, combination of vehicle and the route. Therefore, this study aims to develop mathematical model that optimize these three factors integration to minimize the emission cost. The results of this research are the mathematical model, optimization of the development of the Simulated Annealing (SA) method that is applied to the problem is able to get a reduction in total emissions costs up to 18.8%.

Abstract

Aviation industry often faced uncertainty demand and high level of cancellation. Revenue management in the airline is related to demand management policies to classify and estimate the various requests of pricing and capacity control. This study will develop airline revenue management model integrates luggage passengers with air cargo based on the control of air cargo space. The airline must pay attention to customer behavior due to high cancellation and no-show. In this case we deal with the aspect of the overbooking in which one of the ways to reduce the cost of spoilage due to cancellation or no show. Moreover, in this proposed model, we discuss the expected revenue function to maximize the expected revenue from the policies of accept or reject the booking requests between passengers and air cargo by the same airline. This study aims to develop expected revenue in the dynamic programming model in order to maximize the revenue expectations of the policy of accepting and rejecting booking request between passengers with air cargo in the same airline.

Abstract

Loading containers into a vessel can be delayed because of inefficient processes in the container yard. These container yard inefficient processes can be caused by inappropriate stacking position and inefficient crane operation. Inappropriate containers stacking positions may need some preparatory jobs of rearranging containers ahead of loading time to reduce delays in the process. The method will allow preparatory jobs to be scheduled together with main jobs to optimize use of the idle time of ASCs. This research aims to find a better scheduling strategy of twin ASCs as well as improving land utilization in a vertical-layout container yard to minimize delays in containers loading process. The uncertainty of truck arrival is accomodated by implementing iterative rescheduling in look-ahead planning horizon. The algorithm finds the optimal position of the container in the yard by implementing scoring function for each available slot. Finally, some numerical experiments are conducted to prove the performance of the algorithm.
