“…Kimms and Kozeletskyi (2016a) study core-based allocations in the cooperative traveling salesman problem, while Kimms and Kozeletskyi (2016b) use Shapley value-based cost allocation in the cooperative traveling salesman problem under rolling horizon planning. Schulte et al (2017). In addition to cost savings of 25%, Muñoz-Villamizar et al (2015) observe a 9% reduction in the number of routes and a 10% increase in vehicle utilization-factors which can in turn reduce emissions and congestion.…”

Competitive markets, increased fuel costs, and underutilized vehicle fleets are characteristics that currently define the logistics sector. Given an increasing pressure to act in a manner that is economically and ecologically efficient, mechanisms that help to benefit from idle capacities are on the rise. In the Sharing Economy, collaborative usage is typically organized through platforms that facilitate the exchange of goods or services. Our study examines a collaborative pickup and delivery problem where carriers can exchange customer requests. The aim is to quantify the potential of horizontal collaborations under a centralized framework. An Adaptive Large Neighborhood Search is developed to solve yet unsolved test instances. A computational study confirms the results of past studies which have reported cost savings between 20 and 30%. In addition, the numerical results indicate an even greater potential for settings with a high degree of regional customer overlap. Unfortunately, these high collaborative gains typically come at the cost of an uneven customer distribution, which is known to be one of the main barriers that prevent companies from entering into horizontal collaborations. To generate acceptable solutions for all participants, several constraints are included in the model. The introduction of these constraints to single-vehicle instances, decreases the potential collaborative gain considerably. Surprisingly, this does not happen in more realistic settings of carriers operating multiple vehicles. Overall, the computational study shows that centralized collaborative frameworks have the potential to generate considerable cost savings, while at the same time limiting customer or profit share losses and enabling carriers to keep some of their most valued customers.

“…Minh and Huynh [44] applied the diffusion approximation M/G/n queuing model to provide an analytical tool for assessing and optimizing the gate layout for a given truck arrival rate and truck service rate under two gate queuing strategies: pooled and non-pooled. Schulte et al [45] introduced a collaborative planning model to be operated within a truck appointment systems (TAS) and to investigate its impact on emission and cost objectives. Chen et al [46] proposed a methodology to optimize truck arrival patterns to reduce emissions from idling truck engines at marine container terminals and developed a bi-objective model to minimize both truck waiting times and truck arrival pattern change.…”

With the rapid development of world economy and trade and the continuous construction of green port, automated container terminal (ACT) has increasingly become the direction of future development. Layout design is the premise of ACT construction, which has an at least 50-year influence on the terminal. Therefore, this paper hopes to analyze and design the typical ACT layout to achieve sustainable development of the port. Firstly, a conceptual model is presented considering the interaction between different areas within the ACT when the width and length of the terminal are fixed. To select the optimal layout to achieve the goal of the green terminal, a novel mathematical model is established based on the energy consumption during cycle operation of various devices which can estimate the total carbon emission of an ACT over a period and is suitable for designing period. Then, with the developed model, an ACT in East China was taken as a case study. Finally, according to various analysis of the data results, the layout suggestion considering the sustainable development of the port is given.

“…Englert et al [18] have examined the impact a potential inland port would have on pollution and congestion caused by empty truck repositioning in the Southern California region. In the same realm, Schulte et al [24,25] have proposed an appointment system and a corresponding mathematical planning model to reduce port-related truck emissions by means of collaboration among truckers and trucking companies for a real world case. An established approach to integrate cost and pollution objectives in an objective function has been presented by Bektaş and Laporte [26].…”

“…Thus, an integrated objective function may be formed as a sum of cost terms. Alternatively, other authors [25,26] have applied an emission price for the same purpose. This approach reflects the assumption that regulators may charge companies with a certain fee on their produced emissions.…”

International trade imbalances make the management of empty containers within shipping networks an important economic and ecological problem. While import-dominated ports accumulate large amounts of empty containers, export-dominated ports need them as transport resources, requiring a repositioning transportation of empty containers on the sea and land side. Acknowledging the importance of the problem, plenty of respective literature has appeared. Since periodic review inventory management systems allow to model the inherent stochasticity of empty container transportation, they have emerged as a major solution approach in the domain. Nevertheless, existing approaches often omit crucial economic and ecological real world conditions determining the success of empty container management. Pollution, repair options, and street-turns are important aspects in this context. In this work, we present new stochastic review policies incorporating a realistic allocation scheme for empty container emissions, realistic maintenance, and repair options as well as street-turns. We analyze the optimality of the proposed polices and evaluate them in a simulation model with metaheuristic parameter search based on extensive real-world data from a major global shipping company operating in Latin America. Results provide insights for academics and practitioners about the economic and ecological impact of the distinct empty container management polices within a shipping network.
