This paper evaluates an alternative queuing concept for marine container terminals that utilize a truck appointment system (TAS). Instead of having all lanes providing service to trucks with appointments, this study considers the case where walk-in lanes are provided to serve those trucks with no appointments or trucks with appointments but arrived late due to traffic congestion.

To enable the analysis of the proposed alternative queuing strategy, the queuing system is shown mathematically to be stationary. Due to the complexity of the model, a discrete event simulation (DES) model is used to obtain the average waiting number of trucks per lane for both types of service lanes: TAS-lanes and walk-in lanes.

The numerical experiment results indicated that the considered queuing strategy is most beneficial when the utilization of the TAS lanes is expected to be much higher than that of the walk-in lanes.

The novelty of this study is that it examines the scenario where trucks with appointments switch to the walk-in lanes upon arrival if the TAS-lane server is occupied and the walk-in lane server is not occupied. This queuing strategy/policy could reduce the average waiting time of trucks at marine container terminals. Approximation equations are provided to assist practitioners calculate the average truck queue length and the average truck queuing time for this type of queuing system.

This paper presents a generic simulation model to determine the equipment mix (quay, yard and intra-terminal transfer) for a Container Terminal Logistics Operations System (CTLOS). The simulation model for the CTLOS, a typical type of discrete event dynamic system (DEDS), consists of three sub-models: ship queue, loading-unloading operations and yard-gate operations. The simulation model is empirically applied to phase 1 of the Yangshan Deep Water Port in Shanghai. This study considers different scenarios in terms of container throughput levels, equipment utilization rates, and operational bottlenecks, and presents a sensitivity analysis to evaluate and choose reasonable equipment ratio ranges under different operational conditions.

The construction industry is reluctant to utilize construction logistics centres (CLC). To understand why, the purpose of the study is to increase the understanding of drivers and challenges of CLC utilization.

Adopting an activity-based cost methodology, nine construction projects' CLC utilization in a Swedish urban development project is analyzed for a time period of three years (2013–2016).

There is a difference between drivers and challenges for implementing and utilizing CLCs, which are often implemented to reduce third-party disturbances. The drivers to utilize a CLC, however, stem from achieving efficient logistics. The authors identify two different utilization strategies; the CLC is used either for just-in-time (JIT) deliveries or as a consolidation point.

The study shows that construction logistics is to some extent repeating some mistakes of its big brother, city logistics. The study hypothesizes that there are differences between CLC implementation and utilization drivers and challenges that are often overlooked, which can explain the lack of CLC utilization.

The study shows that it is crucial for construction projects to develop and formulate a logistics strategy for how to utilize the setup, i.e. deciding whether to use the setup as a consolidation point leading to fewer deliveries and more materials on-site, or as JIT, leading to more deliveries but fewer materials on-site.

CLCs can reduce environmental impact and third-party disturbances. However, to make this come true, acceptance among the users is needed. The study provides understanding of drivers and barriers for CLC implementation and utilization that can increase acceptance among users (i.e. construction projects).

The current study is one of the first studies to analyze CLC utilization.

The paper proposes a framework for the successful deployment of Industry 4.0 (I4.0) principles in the aerospace industry, based on identified success factors. The paper challenges the perception of I4.0 being aligned with de-skilling and personnel reduction and instead promotes a route to successful deployment centred on upskilling and retaining personnel for future role requirements.

The research methodology involved a literature review and industrial data collection via questionnaires to develop and validate the framework. The questionnaire was sent to a purposive sample of 50 respondents working in operations, and a response rate of 90% was achieved. Content analysis was used to identify patterns, themes, or biases, and the data were tabulated based on specific common attributes. The proposed framework consists of a series of gates and criteria that must be met before progressing to the next gate.

The proposed framework provides a feedback mechanism to review minimum standards for successful deployment, aligned with new developments in capability and technology, and ensures quality assessment at each gate. The paper highlights the potential benefits of I4.0 implementation in the aerospace industry, including reducing operational costs and improving competitiveness by eliminating variation in manufacturing processes. The identified success factors were used to define the framework, and the identified failure points were used to form mitigation actions or controls for inclusion in the framework.

The paper provides a framework for the successful deployment of I4.0 principles in the aerospace industry, based on identified success factors. The framework challenges the perception of I4.0 as being aligned with de-skilling and personnel reduction and instead promotes a route to successful deployment centred on upskilling and retaining personnel for future role requirements. The framework can be used as a guideline for organizations to deploy I4.0 principles successfully and improve competitiveness.

This study aims to focus on creating sales capability as part of new product development (NPD). The aim is to define generic requirements for building sales capability as a part of NPD and to propose a necessary process by defining key activities for sales readiness.

An inductive and qualitative research method was used to construct a sales capability creation process based on a current state analysis in seven companies.

The results indicate that the status of companies’ sales-related planning varies during the NPD, and the related activities are not systematically managed. Considering sales early is necessary to enable a smooth and cost-efficient start of sales, and to avoid unnecessary delays and problems in other functions. At the same time, the companies recognise the need for improvement.

This paper presents a potential process including systematic activities for creating sales capability in conjunction with product development, which is novel to the literature. The proposed process is applicable in aligning industrial company needs.

This study describes how maintenance capability should be created during the design and construction phases of construction projects. Purpose of the abstract to define the elements for creating the maintenance capability and the process to be used in construction life cycle projects for buildings.

An inductive and qualitative research method was used to construct the proposed process based on the literature and 18 interviews in two large construction companies.

The results indicate that the maintenance phase is usually overlooked during the design and construction phases, and capabilities are not systematically built. In particular, processes are lacking in data management, causing severe problems in maintenance.

This study presents a process including key requirements and activities for creating maintenance capability in conjunction with the design and construction phases, which is novel to the literature. The validated process can be adapted based on the needs of the construction company.

The purpose of this paper is to model the impact of geotourism on geoconservation by observing two popular geotourism activities, namely, rock climbing and hiking. It proposes that as much as geotourism activities have potential negative impacts, they can also bring about positive modification of critical ecosystems like that of Hell’s Gate National Park.

This research opted for an exploratory research design using both open and close-ended questionnaires from 351 respondents and was complemented by documentary analysis. The statistical relationship between geotourism activities and geoconservation was modelled through linear regression.

As predicted the computation using hiking and rock climbing to predict geoconservation were significant with p = 0.004 < 0.05 and p = 0.002 < 0.05, respectively. Implying that selected geotourism activity(s) are positively related to geoconservation

Recognizing the symbiotic relationship, values and relevance of geotourism to geoconservation as a dynamic approach to preservation of protected area management is central to promoting ecosystem stewardship and contributes to the achievement of United Nations development goals.

This paper fulfils an identified need to study how geotourism activities can be used to preserve/conserve the ecological environments and geoheritage of a destination

This paper aims to provide rigor and clarity to the current coronavirus disease 2019 (COVID-19) policy debate in Vietnam. It is intended to serve a three-fold purpose. First, it critically examines the framing of policy objectives and the utilization of policy instruments for controlling COVID-19 in Vietnam. Second, it goes beyond policy design to consider the coordination and implementation of COVID-19 policies in Vietnam. Third, it discusses policy measures needed for post-COVID sustainable and inclusive growth, especially the sharing of the public costs of COVID-19 policies.

The paper employs a positivist research framework that emphasizes the causal relationships between the variables under study. The method of analysis is mixed, combining both qualitative and quantitative techniques. In particular, a simple, theoretical model is constructed to evaluate the welfare effects of alternative vaccine strategies. No primary data were collected.

The Vietnamese government’s dual goals of containing the pandemic and maintaining economic growth, while being reasonable, need clarification and updating. It is argued that in the longer term, there is no trade-off between saving lives and protecting the economy. The downward revision of the projected growth rate and commitment to a coherent and transparent vaccination strategy is the best way to move forward in Vietnam. The choice of vaccine rollout order involves a consideration of ethics. It is suggested that it is appropriate to vaccinate elderly people and people with underlying medical conditions first. Complementary policy measures to stimulate aggregate demand and supply need to be expanded but also more targeted. Effective coordination and implementation of COVID-19 policies remain a serious challenge for Vietnam. Finally, inclusive growth and sustainable development should take account of human capital development and distributive justice.

The paper proposes a number of policy measures which have social impact. These include the government's formal commitment to a vaccine first strategy and a relief package of essential goods to poor and disadvantaged households.

The paper contributes positively to the current COVID-19 policy formulation by providing rigor and clarity to the framing of policy objectives and the utilization of policy instruments. While vaccination has been adopted as a national policy instrument, its design and implementation can be much improved. The paper recommends an appropriate vaccine strategy for Vietnam. It also draws attention to other dimensions of successful policies, namely, communication, coordination, implementation and distributive justice.

Egypt has set plans to transform into a green economy which requires major reforms in the waste sector as one of the most vital sectors crucial for this transformation. This study aims at inspecting the current status of the Egyptian waste sector to highlight the major policy reforms needed. Furthermore, it assesses the economic viability of establishing waste-to-energy (WtE) projects under the current regulations that govern the sector.

The study employed an inductive analytical approach to scrutinize the institutional and regulatory framework of the waste and WtE sectors. Furthermore, a novel techno-economic analysis was conducted to assess the profitability of a WtE plant that employs moving grate incineration technology.

The analysis of the waste sector revealed its deteriorating state and the dire need for immediate restructuring through more stringent regulations to establish an integrated waste management system (IWMS) that incorporates WtE technologies as well as a number of corrective actions that would help enhance the sector. Additionally, the techno-economic analysis revealed the need to amend the current WtE regulation to comprise a gate fee as an indispensable revenue stream for WtE projects.

This study is one of a few studies that uses a new technique of analysis to explore the potential role that WtE projects can play in Egypt as a part of an IWMS that aims at transforming the waste sector into a resource sector while providing a renewable and sustainable source of energy.

This paper outlines how Design for Lean Six Sigma methods aided a medical device manufacturing company in developing a new strategic space management and approval process for its manufacturing site.

The project demonstrates the application of the Design for Lean Six Sigma and structured Define, Measure, Analyse, Design, and Verify methodology in designing and implementing a process that enables the case study manufacturing site to improve its space utilisation and free up space.

The project was validated in one manufacturing department, and the Design for Lean Six Sigma methodology resulted in creating 15% new space for that area, with opportunities identified to free up 44.7% of the total manufacturing floor space and realise over €2.2 million cost savings as well as start to manufacture new products launched.

The manuscript highlights for the first time how the Design for Lean Six Sigma methodology can be utilised for space utilisation and can be leveraged by other manufacturers. The current study's limitations are that it is a single-site case study application. Future longitudinal case studies on Design for Lean Six Sigma application in more manufacturing space utilisation projects would be useful. This study has implications for identifying best practices for Design for Lean Six Sigma methodology application in the device industry, thus improving the state of the art for introducing new manufacturing lines.

This is the first published work to utilise Design for Lean Six Sigma methodology for space utilisation in a medical device company. This review will provide medical devices and other manufacturing organisations with recommendations on utilising Design for Lean Six Sigma and design for improved space utilisation to reduce costs.
