This paper aims to model maintenance planning with a dynamic opportunistic approach for a job-shop production system. One issue in such a system is the positive or negative economic dependency. That is grouping maintenance activities may decrease or increase system costs. Furthermore, many...

On-shore power supply (OPS) is a promising energy-saving and carbon emission-reduction technology for ports. The world’s leading container terminals are accelerating the deployment of OPS facilities, but the problem of low OPS utilization has always plagued the transformation and upgrading of...

This paper proposes a branch-and-bound algorithm (B&B) for the proactive scheduling problem, which incorporates a degree of anticipation for variability in practical projects. First, the resource-constrained proactive scheduling model is formulated. Second, solving its resource-unconstrained...

As water transportation undergoes a new technological revolution, automated terminal technology has become a key issue in reducing costs and improving efficiency. However, the operation theory limitation makes it problematic for machines to cooperate effectively and operate profitably, which is...

In this paper we consider, for the first time, the setup and travel times of cranes in the berth allocation and quay crane assignment problem. We first propose a new mixed integer linear programming model (MILP) for the problem without setups (BACASP), in which neither the berthing positions nor...

Purpose: Implementing process management methodology through Lean Management and Design Thinking provides a new way to manage surgical blocks, maximize efficiency and adapt to the high variability of demand. This article presents our experience of implementing a set of improvement actions within...
