Recent Progress Using Matheuristics for Strategic Maritime Inventory Routing
نویسندگان
چکیده
This paper presents an extensive computational study of simple, but prominent matheuristics (i.e., heuristics that rely on mathematical programming models) to find high quality ship schedules and inventory policies for a class of maritime inventory routing problems. Our computational experiments are performed on a set of the publicly available MIRPLib instances. This class of inventory routing problems has few constraints relative to some operational problems, but has long planning horizons, which make the time dimension challenging. We compare several variants of rolling horizon heuristics, K-opt heuristics, local branching, solution polishing, and hybrids thereof. Many of these matheuristics substantially outperform the commercial mixed-integer programming solvers CPLEX 12.6.2 and Gurobi 6.5 in their ability to quickly find high quality solutions. New best known incumbents are found for 26 out of 70 yet-to-be-proved-optimal instances and new best known bounds on 56 instances.

A realistic perish ability inventory management for location-inventory-routing problem based on Genetic Algorithm
In this paper, it was an attempt to be present a practical perishability inventory model. The proposed model adds using spoilage of products and variable prices within a time period to a recently published location-inventory-routing model in order to make it more realistic. Aforementioned model by integration of strategic, tactical and operational level decisions produces better results for sup...
متن کاملA survey on matheuristics for routing problems
In this paper we survey the literature on matheuristics proposed to solve vehicle routing problems. A matheuristic makes use of mathematical programming models in a heuristic framework. Matheuristics have been applied to several different routing problems and include a number of different approaches. We propose a classification in three classes of the matheuristics: decomposition approaches, im...
متن کاملMIRPLib - A library of maritime inventory routing problem instances: Survey, core model, and benchmark results
This paper presents a detailed description of a particular class of deterministic single product maritime inventory routing problems (MIRPs), which we call deep-sea MIRPs with inventory tracking at every port. This class involves vessel travel times between ports that are significantly longer than the time spent in port and require inventory levels at all ports to be monitored throughout the pl...
متن کاملMatheuristics for a Multi-attribute Profit Collecting Vehicle Routing Problem
This paper studies a multi-attribute profit collecting vehicle routing problem, which arises in the collection operations of a charity organisation in the UK. The problem involves a heterogeneous fleet consisting of vehicles of different capacities, mandatory visits to a subset of vertices, time windows, rest requirements associated with maximum driving and working times, and partial collection...
