Enterprise logistics: the right tool for the job

With ever‐increasing profit and competitive pressures, manufacturers are looking toward the logistics process as a source of competitive advantage. A number of methodologies and information systems have evolved as ‘tools’ to aid in the exploitation of the potential of logistics. Many manufacturers have benefited significantly from the application of logistics tools. For others, primarily …

Variable very large neighbourhood algorithms for truck sequencing at transshi…

This paper considers a scheduling problem motivated by transshipment terminals. Trucks delivering or picking up items at the terminal have to be sequenced. Here, inventory constraints must be considered, that is the current inventory level implied by initial inventory level, total pick up quantity up to this moment and total delivery quantity up to this moment must not be negative and must not …

Scheduling trucks in container terminals using a genetic algorithm

Trucks are the most popular transport equipment in most mega-terminals, and scheduling them to minimize makespan is a challenge that this article addresses and attempts to resolve. Specifically, the problem of scheduling a fleet of trucks to perform a set of transportation jobs with sequence dependent processing times and different ready times is investigated, and the use of a genetic algorithm…

Scheduling operations of a rail crane and container deliveries between rail a…

This article addresses the problem of scheduling container transfer operations in rail terminals. The overall problem can be divided into three smaller problems: constructing a dual-cycle delivery task by matching inbound and outbound containers; determining parking positions for trucks; and sequencing the delivery tasks for transfer by the rail crane. This article provides a mathematical model…

Scheduling material handling vehicles in a container terminal

Increasing global trade has created the need for efficient container ports. The goal of the port is to move containers as quickly as possible and at the least possible cost. Goods that are delayed at the port are inevitably tardy when delivered to the customer, and thus sanctioned by late charges. Two key activities in the port are (i) unloading of containers from truck and then storage in the …

Quay crane scheduling in container terminals

The problem of scheduling identical quay cranes moving along a common linear rail to handle containers for a ship is studied. The ship has a number of container-stacking compartments called bays, and only one quay crane can work on a bay at the same time. The objective of the scheduling problem is to find the work schedule for each quay crane which minimizes the ship’s stay time in port. Find…

Hybrid Estimation of Distribution Algorithm for the Quay Crane Scheduling Pro…

The competitiveness of a container terminal is highly conditioned by the time that container vessels spend on it. The proper scheduling of the quay cranes can reduce this time and allows a container terminal to be more attractive to shipping companies. The goal of the Quay Crane Scheduling Problem (QCSP) is to minimize the handling time of the available quay cranes when performing the tasks of …

Gantry Crane Scheduling with Interference Constraints in Railway Container Te…

Railway container terminals, where gantry cranes are responsible for loading and unloading containers between freight trains and yards, are important hubs of hinterland logistics transportation. Terminal managers confront the challenge in improving the efficiency of their service. As the most expensive equipment in a terminal, the operational performance of gantry cranes is a crucial factor. In…

Logistics project scheduling problem in indeterminate environment is gaining more and more attention in recent years. One effective way to cope with indeterminacy is to develop robust baseline schedule. There exist many related researches on building robust schedule in stochastic environment, where historical data is sufficient to learn probability distributions. However, when historical data i…

Reverse logistics capabilities: antecedents and cost savings

The use of reverse logistics has received increased attention in the literature, although the role that reverse logistics capabilities plays in enabling firms to achieve cost savings has not been empirically examined. Reverse logistics capabilities can enable retailers to enhance their return policies and improve their overall cost position. This paper aims to address these issues.

Port yard storage optimization

The Port Yard Storage Optimization Problem (PYSOP) originates from space allocation needs at the Port of Singapore. Space allocated to cargo is to be minimized in a designated yard within a time interval. The problem is akin to a packing problem in space and time, but where shapes packed and constraints are particular to port operations. Further, space requests can change within the time interv…

A genetic algorithm heuristic for solving the quay crane scheduling problem w…

One of the most important operations in marine container terminals is quay crane scheduling. The quay crane scheduling problem (QCSP) involves scheduling groups of containers to be loaded and unloaded by each quay crane. It also requires addressing practical issues such as minimum spacing between quay cranes and precedence relationships between container groups. This study addresses the QCSP wi…

A survey on reverse logistics system of mobile phone industry in Hong Kong

It is not surprising that proper implementation of reverse logistics systems can result in better customer loyalty and reduction in operational costs due to reuse or remanufacturing of some parts. This is particularly important for those industries with a short product life cycle, like the mobile phone industry. The major objective of this paper is to present the results of a pilot survey with …

A critical-shaking neighborhood search for the yard allocation problem

The yard allocation problem (YAP) is a real-life resource allocation problem faced by the Port of Singapore Authority (PSA). As the problem is NP-hard, we propose an effective meta-heuristic procedure, named critical-shaking neighborhood search. Extensive experiments have shown that the new method can produce higher quality solutions in a much shorter time, as compared with other meta-heuris…

Semi-variable delivery routes and the efficiency of outbound logistics

Maintaining efficiency in despatching goods from a depot to geographically dispersed customers may require management at the depot to adjust its delivery routes daily if these customers’ demands fluctuate from day to day. One type of adjustment is to give drivers daily “skip lists” instructing them not to visit customers who have indicated that they do not need delivery on the day in qu…
