Abstract
There is significant amount of literature tackling different issues related to the port industry. The present chapter focuses on a single business unit of seaports aiming at the documentation of works related to container terminals.
An effort to review, collect and present the majority of the works present in the last 30 years, between 1980 and 2010, has been made in order to picture the problems dealt and methods used by the authors in the specific research field. To facilitate the reader, studies have been grouped under five categories of addressed problems (productivity and competitiveness, yard and equipment utilization, equipment scheduling, berth planning, loading/unloading) and four modelling methodologies (mathematics and operations research, management and economics, simulation, stochastic modelling).
The analysis shows that most works focus on productivity and competitiveness issues followed by yard and equipment utilisation and equipment scheduling. In reference to the methodologies used managerial and economic approaches lead, followed by mathematics and operations research.
In reference to future research, two fields have been identified where there is scope of significant contribution by the academic community: container terminal security and container terminal supply chain integration.
The present chapter provides the framework for researchers in the field of port container terminals to picture the so far works in this research area and enables the identification of gaps at both research question and methodology level for further research.

Abstract
Purpose
This paper aims to examine the reliability of a cooling seawater pumping station which pumps seawater to refineries and petrochemical plants in Kuwait mainly for cooling purposes. Owing to the harsh operating climate and the lack of other alternative sources of water, high reliability of the pumping system is crucially important.
Design/methodology/approach
The reliability of a system can be considered from different views. The one taken in this study is to measure the reliability of the cooling seawater arriving to the consumer at the required pressure and flow rate while observing the operational constraints on the system. A reliability model has been developed and applied to the actual data from the pumping station.
Findings
The preliminary results indicate that the model could be a useful tool to assess the current condition of the system and to find ways of improving system reliability and availability.
Originality/value
The paper provides information of value to all concerned with relibility management.

Abstract
Information technology has become an essential part of the rapid and accurate transfer and processing of enormous volumes of data processed in international transport firms and port organisations. The proper management of systems, which process this information and communicate it to those who manage port operations, is vital for efficient transport. This explains why container‐tracking systems are given high priority among operational computer applications in ports. Investigates the importance of information technology and its role in improving the operational systems in cargo handling. A computer simulation model is developed to compare two different operational systems – a container terminal equipped with electronic devices versus a terminal without such devices. The importance of information technology in supply‐chain management is also discussed.

Abstract
Purpose
Real flight is cognitively demanding; accordingly, both indicators and display panel layout should be user-friendly to improve pilot-aircraft interaction. Poor pilot-interface interactions in aircrafts could result in accidents. Although a general reason of accidents is improper displays, relatively few studies were conducted on interfaces. This study aims to present an optimization model to create intuitively integrated user-friendly cockpit interfaces.
Design/methodology/approach
Subjectivity within most usability evaluation techniques could bring about interface design problems. A priori information about indicator’s possible locations may be available or unavailable. Thus different analytical approaches must be applied for modifications and new interface designs. Relative layout design (RLD) model was developed and used in new interface designs to optimize locations of indicators. This model was based on layout optimization and constructed in accordance with design requirements, ergonomic considerations with the pilot preferences. RLD model optimizes interface design by deploying indicators to the best locations to improve usability of display panel, pilot-aircraft interaction and flight safety.
Findings
Optimum interfaces for two problem instances were gathered by RLD model in 15.77 CPU(s) with 10 indicators and 542.51 CPU(s) with 19 indicators. A comparison between relative and existing cockpit interfaces reveals that locations of six navigation and four mechanical system indicators are different. The differences may stem from pilots’ preferences and relativity constraints. Both interfaces are more similar for the central part of the display panel. The objective function value of relative interface design (Opt: 527938) is far better than existing interface (737100). The RLD model improved usability of existing interface (28.61 per cent considering decrease in the objective function values from 737100 to 527938.
Practical implications
Future cockpit and new helicopter interface designs may involve RLD model as an alternative interface design tool. Furthermore, other layout optimization problems, e.g. circuit boards, microchips and engines, etc. could be handled in a more realistic manner by RLD model.
Originality/value
Originality and impact of this study related to development and employment of a new optimization model (RLD) on cockpit interface design for the first time. Engineering requirements, human factors, ergonomics and pilots’ preferences are simultaneously considered in the RLD model. The subjectivity within usability evaluation techniques could be diminished in this way. The contributions of RLD model to classical facility layout models are relativity constraints with the physical constrictions and ergonomic objective function weights. Novelty of this paper is the development and employment of a new optimization model (RLD) to locate indicators.

Abstract
This paper examines the port of Mombasa’s attempted implementation of computer-based terminal operating systems (TOS); the challenges faced and the outcomes. In addition to enhancing its operations efficiency, a key motivation for the technology was to facilitate better integration and connectivity to the Belt and Road as a key gateway along the key route. It utilised a qualitative single-case methodology, involving a combination of semi-structured interviews, non-participant observations and content analysis of relevant policy documents and reports provided by the port. The paper finds that the attempt to adopt and implement TOS at the port mostly failed as a result of a complex combination of technological, organisational and environmental factors. Most importantly, the wider business environment was ill equipped with the necessary information communication technology (ICT) infrastructure to support effective implementation. There was also a general lack of appropriately skilled workers to support and drive the same.

Abstract
The concrete building products manufacturing industry supplies 2,000‐4,000 precast concrete building products to the construction industry. Owing to seasonal demand, the industry builds up stock in winter to meet the high demand in summer. As concrete products are heavy and vary in shape and size, proper stocking in terms of layout and methods of stocking of products on the yard is essential. Industrial practice suggests that stockyard space management gets less attention during strategic and budget planning as it is left to the stockyard manager. The industry experiences space congestion for both the storage and dispatch of products. During dispatch process, greater retrieval time is required, long queues of lorries (shipping vehicles) are formed and desired level of service cannot be maintained. Presents a review of stockyard operations, analysis of parameters affecting loading and dispatch process on the yard and strategies to optimise the stockyard layout. It is expected that proper layout planning will reduce the cost of delivery of products by 5‐10 per cent in the industry where profit is less than 5‐8 per cent.

Abstract
Purpose
The design of the emergency department (ED) requires high precision in the process of distributing spaces. An increase in population and continuous development during the past years caused the addition of new services, changes in patients’ numbers, movement flow and treatment procedures which makes the existing layout plan of the ED no longer appropriate for its current needs. Therefore, the purpose of this paper is to generate a process of finding better alternatives for ED’s spatial planning.
Design/methodology/approach
The genetic algorithm method as a part of the systematic layout planning strategy was adopted for decision-making in redesigning the ED layout and finding the most appropriate alternative. This methodology was applied to a teaching hospital in Jordan to create layout alternatives with better functional dimensions.
Findings
The design that is based on the study of the movement of users and the relationship of spaces increases the layout performance.
Research limitations/implications
The structural method of this study can be adopted for different hospital designs, but the results are limited only to the study case itself because of the different factors and data for each building.
Originality/value
This study demonstrates the process of making the most appropriate decision to redesign the ED in the hospital; therefore, the method can be adopted in restructuring the scheme of different hospitals and evaluated, especially before implementation.

Abstract
Purpose
In spite of having a number of general‐purpose algorithms for solving plant layout problems, facility planners may still face a challenging task to adjust these algorithms to handle special, but not uncommon, layout problems. The purpose of this study is to propose a new method for addressing the impact of overhead space utilization on a plant layout solution.
Design/methodology/approach
A new method for adjusting material flow under a mixed floor and overhead material handling condition is incorporated in an existing plant layout procedure. A case study involving the layout improvement in a lawn mower engine assembly facility is presented to illustrate the effectiveness of the proposed method.
Findings
The analysis of solutions for the case study shows that the layout generated by the proposed modified material flow approach is a more economical solution. The case also shows, when it is important to optimize the use of space, the overhead space should be considered as part of any methodology for designing a good layout.
Research limitations/implications
The proposed modified material flow approach can be applied to any facility where the use of overhead space for material handling is justifiable by limited floor space and/or by high cost of land. The proposed method can be applied to small to medium size problems with minimal computational effort. However, as the size of facility grows, the manual calculation becomes more time consuming and potentially erratic.
Originality/value
This paper should be useful to both researchers and practitioners who deal with overhead space utilization in designing facility layouts.

Abstract
Purpose
The purpose of this paper is to classify research on information and communication technology (ICT) for logistics and freight transportation on the basis of the main themes and methods and proposes directions for future research.
Design/methodology/approach
The review is based on 44 papers published from 1994 to 2009 in international peer‐reviewed journals. The academic papers are analysed and classified according to the research methodology adopted and the themes addressed.
Findings
While there are many contributions taking the “public transportation” perspective (i.e. the viewpoint of public stakeholders), papers focussing on the “private transportation” perspective (i.e. the viewpoint of the private companies offering logistics and transportation services) are fewer and relatively more recent. Additionally, even though in recent years researchers have also started to examine the decision‐making process of ICT adoption, many themes are under‐represented in literature, such as the subject of integration among different application types, empirical research on ICT adoption and the role of technology providers in the adoption process. As far as the methodology is concerned, the review revealed that many of the papers examined are either conceptual papers or empirical studies (i.e. mostly based on surveys, or else on case studies or interviews), while simulation and modelling are rarely present.
Research limitations/implications
While efforts were made to be all‐inclusive, significant research efforts may have been inadvertently omitted. However, the authors believe that this review is an accurate representation of the body of research on ICT for logistics and transportation companies published during the specified timeframe, and feel that confidence may be placed on the resulting assessments.
Originality/value
The paper offers a guide for the review of previous research on this topic and identifies the most important issues that need to be addressed in future research.

Abstract
Purpose
The purpose of this paper is to present a parametric model to assess the impacts of information and communication technology (ICT) applications on company freight transportation processes (i.e. “company” perspective). The aim is to support both internal monitoring procedures and the decision‐making process of ICT adoption, as well as increase managers' awareness of these solutions in improving their business. The model has been applied to inter‐modal terminal processes, which are particularly critical due to the high number of players involved and the need for integrating different modes of transport throughout the whole delivery process.
Design/methodology/approach
The present study is part of a broader research on the topic of ICT adoption in the freight transportation industry. Based on the outcome of the previous stages of this research, the impact of ICT applications on inter‐modal processes has been modeled using an activity‐based costing approach. Interviews were conducted with both inter‐modal terminal managers and technology providers to collect the required inputs and validate the model. A case study has been performed to apply the model and a further sensitivity analysis has been carried out.
Findings
The application of the model to the examined inter‐modal terminal showed that the most significant “as is” costs are those connected to handling activities. Three different ICT scenarios have been also explored. Based on the company “as is” scenario, the model provides an assessment of how and when a positive return on investment can be achieved. Results proved that the benefits deriving from ICT adoption are considerable and depend on the level of technology adopted.
Originality/value
The paper addresses an identified need in the literature of quantifying the impact of ICT for freight transportation. It is one of the few attempts to model costs and benefits of ICT for freight transportation, taking into account the major factors involved. Additionally, the model can be a valuable support to practitioners in evaluating their investments, as well as monitoring their company current performance.
