Abstract: Whilst there has been some limited use of Remotely Piloted Aircraft Systems (RPAS) as part of the response to natural disasters, to date these have typically employed short range mini or micro systems. Using a case study of Cyclone Winston that struck Fiji in February 2016, this chapter demonstrates the potential for long endurance aircraft (LE-RPAS) to support the humanitarian logistic operations through the use of their high quality optics and communications capabilities. In doing so, it offers a high level route map for the development of the people, process and technology requirements that will be needed to underpin the future deployments of LE-RPAS in providing support to humanitarian activities.

Abstract: Recent advances in aviation technology have seen the development of helium-filled “hybrid cargo airships” (HCAs) which have the potential to convey large payloads over significant distances at relatively low cost and with a small carbon footprint. The purpose of this paper is to demonstrate how such HCAs could be used to improve the logistic response to a rapid onset disaster. Through consideration of three recent natural disasters (Typhoon Haiyan – The Philippines – 2013 The Nepal Earthquake – 2015 Cyclone Winston – Fiji – 2016), and drawing on both academic and practitioner literature, this paper provides an overview of how HCAs could potentially provide logistic support to those affected by similar disasters. The paper considers two scenarios: one in which the HCA replaces local truck or sea-based transport from an international airport to the disaster area, and the other in which it operates directly from a United Nations Humanitarian Response Depot to the disaster area. The paper demonstrates that, when compared with the actual response to these three exemplar disasters, in the first scenario the use of HCAs provides a significantly faster but more expensive response whereas in the second scenario, the timeline to supply is longer, but the costs are considerably less. This paper is conceptual in nature, but has been developed through an analysis of the literature related to both HCAs and humanitarian logistics. Given that the emerging generation of HCAs has yet to become fully operational, it will be important to continue to monitor their development and analyse the emerging speed/time/cost parameters in order to ascertain how HCAs might be optimally integrated into the logistic response to a disaster. The significant cargo carrying capacity of an HCA together with its ability to operate from and into ad hoc locations (including those on water) would enable direct delivery from an international airhead or humanitarian response depot to an affected area. This has clear potential to enhance the efficiency, effectiveness and flexibility of post-disaster logistic operations. Whilst there is some emerging discussion of the humanitarian-related use of HCAs in the literature, this generally reflects the technical aspects such as flight control systems and the actual operation of the airships. This paper is the first to offer a practical analysis of how HCAs might be used to support the work of the humanitarian logistician.

Abstract: In typical operations research courses, optimization problems, such as transportation and assignment problems, are frequently discussed and taught as stand-alone problems. An integrated approach may prove to be necessary in order to enable students to have a holistic understanding of a complex problem (e.g., a project). In this paper, a global supply network design problem is presented where the case company can source from multiple “suppliers” using multiple modes of transport (including the use of containers with different capacities), allowing lateral supply between warehouses, etc. As more factors are considered, the problem becomes much more complex than any isolated problem in a typical course. The case was tested in an undergraduate course in Australia, and students found this case challenging but at the same time rewarding once solved.

Abstract: Objective This paper describes the perceptions of operating theatre staff in Australia and The Netherlands regarding the influence of logistical or operational reasons that may affect the scheduling of unplanned surgical cases. It is proposed that logistical or operational issues can influence the priority determination of queue position of surgical cases on the emergency waiting list. Methods A questionnaire was developed and conducted in 15 hospitals across The Netherlands and Australia, targeting anaesthetists, managers, nurses and surgeons. Statistical analyses revolved around these four professional groups. Six hypotheses were then developed and tested based on the responses collected from the participants. Results There were significant differences in perceptions of logistics delay factors across different professional groups when patients were waiting for unplanned surgery. There were also significant differences among different groups when setting logistical priority factors for planning and scheduling unplanned cases. The hypotheses tests confirm these differences, and the findings concur with the paradigmatic differences mentioned in the literature. These paradigmatic differences among the four professional groups may explain some of the tensions encountered when making decisions about scheduling emergency surgical queues, and therefore should be taken into consideration for management of operating theatres. Conclusions Queue positions of patients waiting for unplanned surgery, or emergency surgery, are determined by medical clinicians according to clinicians’ indication of clinical priority. However, operating theatre managers are important in facilitating smooth operations when planning for emergency surgeries. It is necessary for surgeons to understand the logistical challenges faced by managers when requesting logistical priorities for their operations. What is known about the topic? Tensions exist about the efficient use of operating theatres and negotiating in idual surgeon’s demands, especially between surgeons and managers, because in many countries surgeons only work in the hospital and not for the hospital. What does this paper add? The present study examined the logistical effects on functionality and purports the notion that, while recognising the importance of clinical precedence, logistical factors influence queue order to ensure efficient use of operating theatre resources. What are the implications for practitioners? The results indicate that there are differences in the perceptions of healthcare professionals regarding the sequencing of emergency patients. These differences may lead to conflicts in the decision making process about triaging emergency or unplanned surgical cases. A clear understanding of the different perceptions of different functional groups may help address the conflicts that often arise in practice.

Abstract: The purpose of this paper is to investigate the supply chain management (SCM) skills that support the sensing and seizing of opportunities in a changing business environment. Based on the previous literature on the T-shaped model of SCM skills, data were collected through a mail survey among Australian business executives. The resultant skill sets are grouped along factors that support the sensing vs seizing of opportunities. Interestingly from an SCM perspective, functional logistics-related skills are important to maintain competitiveness but are not the ones contributing to a firm’s ability to sense opportunities and threats, and to seize opportunities in a changing business environment. The authors, therefore, support the notion that supply chain managers should be managers first. Factual SCM knowledge is the solid basis, but otherwise only an entry requirement in this field. Problem-solving skills, along with forecasting and customer/supplier relationship management, stand out as important components that support the ability of supply chain managers to sense and shape opportunities and threats in a turbulent business environment. This focus would tend to suggest the importance of supply chain integration and collaboration as management approaches. Other SCM skills from warehousing and inventory management to transportation and purchasing are more prevalent for maintaining competitiveness. The results of the survey and the consequential analysis indicate that the content of tertiary-level educational programmes should be significantly reviewed to deliver two distinct (but partially overlapping) streams that focus on the generalist and functionalist managers who must work together in the management of the increasingly global and complex supply chains. Functional skills often form the basis of training and education programmes for supply chain managers. Whilst these form the solid foundation for their jobs, they are entry requirements at best. In a changing business environment, other skills are needed for success. Given that turbulence is becoming the norm rather than the exception, this finding necessitates rethinking in training and education programmes, as well as in the recruitment of supply chain managers. Testing the T-shaped model of SCM skills from a dynamic capabilities perspective, the results of the factor analysis lead to a regrouping of skill sets in terms of sensing and seizing opportunities in a turbulent business environment.

Abstract: – Whilst implementation of a broad range of reverse logistics (RL) practices is increasingly the norm within commercial supply chain management, they have had limited impact in the humanitarian logistics (HL) sector. The purpose of this paper is to analyse the challenges and opportunities for the application of RL in a HL context. – Through a broad review of both the academic and practitioner literature, supplemented by informal discussions with senior humanitarian logisticians, the paper summarises the current state of RL within the HL sector before recommending ways in which practices that are increasingly found in a commercial context could be implemented. – The findings indicate that, to date, the use of commercial RL practices is extremely limited within the HL sector, but there are a number of areas where their introduction be possible in the future. – Whilst the reviews of the literature were comprehensive, further and more detailed research into the RL practices (if any) undertaken by aid agencies needs to be undertaken in order that appropriate lessons and experiences can be implemented across the sector as a whole. – Given the overall desire of humanitarian agencies to “do no harm” it will be increasingly important for such organisations to embrace RL practices in order to improve the sustainability of their disaster preparation and response activities. – In light of the generally increased awareness of the need to reduce the environmental footprint as well as improving the social and economic impacts of their supply chain activities, there is likely to be increasing pressure on aid agencies to adopt RL practices. This paper identifies some of the potential areas in which this can be undertaken, and the associated barriers to be overcome. – To date, it would appear that no academic research has been undertaken into the RL practices within the HL sector. To this extent, the research represents a first look at a new sub-topic within the overall HL field.

Abstract: The purpose of this paper is to compare perspectives on humanitarian logistics (HL) and supply chain management (SCM) among programmes and logistics/support staff. Underpinned by services supply chain management (SSCM) theory, a single case study of a leading international non-governmental organisation is presented based on a web-based survey of the organisation’s global operations staff, supplemented by semi-structured interviews conducted with senior representatives. The study is believed to be the first to consider the different perspectives of programmes and logistics staff on the interpretation of logistics and SCM. The results indicate both significant ergence between the views of these two cohorts, as well as a general lack of clarity over the concept of SCM, its relationship with logistics and the cross-functional nature of SCM. Insufficient responses from programme staff limit the generalisability of the findings. Suggestions for future research include further examination of the potential of applying SSCM and demand chain management concepts to the humanitarian context. The results support the notion that a broader, more strategic interpretation of SCM, more clearly distinguished from the practice of HL, may assist in breaking down perceived jurisdictional boundaries, bridging the gap between programmes and logistics teams, and strengthening demand-chain influences and the “voice of the beneficiary”. By taking into account the views of non-logisticians, a broader, cross-functional interpretation of SCM is offered leading to revised definitions for both SCM and HL within this sector, together with a framework that integrates SCM across humanitarian relief and development contexts.

Abstract: Container terminals require robust scheduling algorithms for yard cranes to optimally determine the sequence of storage and retrieval operations in yard blocks for higher container terminal performance. This paper investigates the multiple yard crane scheduling problem within a generic yard block and considers the operational restrictions such as the crane noncrossing constraint and models the crane travel time realistically. Further, the fact that any two adjacent cranes must keep an operational safety distance is also taken into consideration. These physical constraints limit the mobility of yard cranes and greatly render the scheduling difficulty for such pieces of equipment. This paper proposes a clustering-reassigning approach, which fully considers all of the operational constraints in practice. The complexity of the approach is o(n 3 ), where n is the number of container moves to be scheduled, making it suitable for real-time scheduling. Numerical experiments and benchmark with a continuous time-based mixed-integer linear programming model indicate that the clustering-reassigning approach can provide satisfactory near optimal solutions for different sets of test cases in a real-time scheduling context.

Abstract: While the use of long-endurance remotely piloted aircraft systems (LE-RPAS) is frequently associated with military operations, their core capabilities of long-range, low-cost and high-quality optics and communications systems have considerable potential benefit in supporting the work of humanitarian logisticians. The purpose of this paper is, therefore, to demonstrate how LE-RPAS could be used to improve the logistic response to a rapid onset disaster. Using the response to the Cyclone Pam that struck Vanuatu in March 2015 as an ex le, this paper provides an overview of how LE-RPAS could be used to support the post-disaster needs assessment and subsequent response processes. In addition, it provides a high-level route map to develop the people, process and technology requirements that would support the operational deployment of the LE-RPAS capabilities. On the basis of the analysis of the published literature and the resultant assessment of the benefits of LE-RPAS to support humanitarian logistic (HL) operations, it is concluded that a formal “proof of concept” trial should be undertaken, and the results be made available to the humanitarian community. This paper is conceptual in nature, but has been developed through an analysis of the literature relating to remotely piloted aircraft systems (RPAS) and HLs. A route map through which the paper’s conclusions can be validated is also offered. LE-RPAS have great potential to provide a swifter understanding of the impact of a disaster, particularly those where the location is remote from the main centres of population. This would allow the affected country’s National Disaster Management Organisation, together with those of supporting countries, to react more efficiently and effectively. In particular, it would allow a swifter transition from a “guess-based” push approach to one that more accurately reflects the disaster’s impact – i.e. a pull-based logistic response. Given the military genesis of RPAS, it will be important to ensure that those engaged in their operation are sensitive to the implications of this. In particular, it will be essential to ensure that any humanitarian operations involving RPAS are undertaken in an ethical way that respects, for ex le, the privacy and safety of the affected population. While there is some emerging discussion on the humanitarian-related use of RPAS in the literature, this generally reflects the operation of small aircraft with limited range and payload capabilities. Useful though such RPAS unquestionably are, this paper expands the discussion of how such systems can support the humanitarian logistician by considering the benefits and challenges of operating long-endurance aircraft.
