(last update Jan 2016)
This is a list of the projects/applications that I have developed or get involved during the past few years. NOTE: this is not very up to date.
Network Inventory Optimization
Note: Involved as a scientific consultant. See [InvOpt] for more details.
Note: Involved as a scientific consultant. See [Retail.Me] for more details.
Vehicle Routing under Uncertainty
Overview: In distribution management, travel time uncertainty is a common issue in practice. This study addresses this issue in the vehicle routing problem (VRP) with deadlines by applying robust optimization and stochastic programming techniques.
Approach(es): Decomposition approach for convex optimization, branch-and-cut algorithm, Benders decomposition.
Production and Inventory Routing Optimization
Overview: This project concerns the development of optimization applications of integrated supply chain operational planning systems. Our main focus is on the production routing problem (PRP), a combined version of the well-known lot-sizing problem (LSP) and the vehicle routing problem (VRP), which jointly optimizes production, inventory, distribution and routing decisions. As a generalization of the PRP, we also extended our approaches to the inventory routing problem (IRP). Efficient exact and heuristic algorithms were developed to tackle the problems in deterministic and stochastic environments in a two-stage and multi-stage fashion.
Approach(es): branch-and-cut algorithm, Benders decomposition based branch-and-cut algorithm, large-scale neighborhood search heuristic.
Truck and Container Loading Optimization
Overview: A real world application concerning a development of an efficient tool to optimize truck and container load utilization in order to minimize the number of required units. The application was developed to handle two types of orders, i.e., splitable (for international shipments) and unsplitable (for domestic shipments), while taking into account several restrictions, e.g., fleet capacity and compatibility, customer specific requirements for fleet composition, tariff benefits, customs compliance, etc.
Approach(es): density-index based greedy heuristic.
Results: cost savings US$1- 2MM per year, and man-hr reduction 10-20 hrs per week
Continuous Move Optimization
Overview: An application from the real world problem in a large cement company. This tool was developed to optimize routing decisions for a fleet of ready mixed concrete vehicles dispatched from multiple pickup locations to a set of customers. The shipment is full truck load but one can attempt to build a set of continuous moves among the pickup and delivery points in order to reduce total empty haul distance, while taking into consideration truck ban restrictions and pickup and delivery time windows.
Approach(es): column generation and two heuristics.
Results: potential operating cost savings between 10% and 37%
Optimization tool for pavement maintenance planning
Overview: This application was part of a government project. It involved a development of an efficient tool to determine optimal pavement maintenance and safety improvement plans for the countrywide network by taking into account an available budget.
Approach(es): MIP based heuristic and a greedy heuristic.
