Abstract

Currently, the European air transport system is experiencing an annual growth of 7%. With an increasing number of flights, airports are reaching their capacity limits and are becoming a bottleneck in the system. Mantea is a European Commission funded project dealing with this issue. This paper focuses on planning decision support tools for airport traffic controllers.

The objective of our planning tools is to achieve a better use of the available airport infrastructure (taxiways and runways). To generate a safe plan, many rules must be taken into account that restrict the usage of airport tarmac: international regulations, airport operational procedures, aircraft performance, weather conditions and sometimes even controller “usual practices”. To generate a realistic plan, extensive monitoring of the traffic situation as well as suitable timing must be achieved. In the life cycle of a flight, 11 out of 15 possible causes of delay occur in an interval of 10-20 minutes, between aircraft start-up request and push-back. This means that precise planning before the end of this period is highly improbable. On the other hand, planning after this period implies the need for fast responses from the system.

In the Mantea project, an architecture is proposed in which a co-operative approach is taken towards planning aircraft movements at the airport. Controllers will be supported by planning tools that help assigning routes and departure times to controlled vehicles, in planning runway allocation (departure sequence) and occupancies, and in monitoring plan progress during flight phases. The planning horizon relates to medium term operations, i.e. 2-20 minutes ahead. The Mantea planning tools implement the following functions: runway departure planning, routing, and plan conformance monitoring. The tools will reduce the controller's workload, increase the level of safety for airport surface movements, and reduce the number of delays and operating costs for the airliners.

In this paper, we will focus on the constraint satisfaction programming techniques used in Mantea for (1) runway departure planning, (2) itinerary search and taxi planning functions. The airport tarmac and runway vicinity air routes have been modelled as a graph. Real time constraints have brought us to develop an algorithm linear in complexity for the itinerary search problem. Operational pressure has led us to develop fast search strategies for scheduling (i.e. use of heuristics, hill climbing…).

Abstract

This chapter is dedicated to the exploration of attitudes toward family planning within marginalized communities in Bangladesh. It begins by elucidating the concept of attitudes and underscoring their significance in the context of family planning. This chapter investigates the intricate relationship between attitudes and family planning decisions, revealing the diverse attitudes prevalent within these marginalized communities. It proposes targeted interventions aimed at breaking down attitudinal barriers that hinder effective family planning practices, with the goal of empowering these communities through a transformative process of attitude change. This comprehensive examination of attitudes toward family planning among marginalized populations contributes valuable insights to the fields of public health and social development.

Abstract

In the last 15 years, the high-growth economic rates of the Russian Federation (RF) have been caused by expansion of the country's participation in the world's raw and energy markets. Now the economic growth opportunities at the expense of these factors are generally exhausted, Russia is faced by problems of high-quality updating of all aspects of socioeconomic and sociopolitical life. These tasks are dictated as external “major challenges” of global character, and internal processes. To confront the challenges and to minimize risks, Russia needs to change the raw model of economic growth which poses the threats for stability of social and economic development.

First, the scientific, technological, and innovative policy which is carried out by industrially developed countries and some new industrial countries is to create the answer to a challenge of maintaining competitiveness and achievement of high productivity rates now. Its purpose is to stimulate development and deployment of advanced technologies, whose productivity significantly exceeds characteristics of traditional technologies.

The happening changes are so considerable that the world enters, perhaps, in the largest technological transition for all history when the richness of natural resources and low cost of work stop being major factors of growth. In total, these changes are estimated as “new industrial revolution” or, in narrower sense, as “technological revolution” which are based on the transition from mass production of the standardized production to the flexible high-performance production which is turning out the individualized products.

In this regard, the productive inclusion in new technological revolution, the implementation of the structural maneuver in economy and social system, can become one of the main objectives for Russia until 2035. The RF should pass a new development model which is based on high-tech industries. It is about the start of the big national project (program) “National Technological Initiative” (NTI).

The implementation of project-planning office functions of NTI is the priority direction of management and modern tool for business which is provided due to the development of NTI planning office, its full-scale expansion, and removal on operational power for support of development and implementation of the plans of measures (“road maps”) of NTI and projects for implementation of “road maps.”

Abstract

As the role of senior school leaders has become more complex, the leadership of improvement, innovation and change has been distributed to middle leaders. However, middle leaders are often not prepared for the shift to strategic thinking and leading. This chapter provides an overview of what it means to think and lead strategically when leading from the middle. Then, the theory is translated into practical templates and tools that can be employed by a middle leader. The context of this chapter is leading a faculty in a secondary school; however, the ideas and examples provided are easily translated to any middle leading context.

Abstract

Tourism planning is an important issue for destination management organizations to satisfy both local community and tourists. This chapter attempts to explain the process and outcomes of a strategic and participative tourism planning project through a case study in Patagonia, Argentina. The general framework of the study, principles of cooperation throughout the project, the geographical information, stages of planning and implementation strategies will be discussed.

Abstract

Purpose

To assess which partnerships were most critical during the recovery planning process following Hurricanes Maria and Irma. We discuss the roles and impact of different types of partners, barriers and facilitators to partnerships and lessons in collaboration during the development of the economic and disaster recovery plan for Puerto Rico.

Design/methodology/approach

The Homeland Security Operational Analysis Center (HSOAC) was tasked with assisting the Puerto Rican government with an assessment of damages from Hurricanes Maria and Irma and the development of the Recovery Plan. During the process, a small team compiled and coded a database of meetings with non-HSOAC partners. The team was divided into sector teams that mirrored FEMA’s Recovery Support Functions. Each sector completed two surveys identifying high impact partners and their roles and contributions, as well as barriers and facilitators to partnerships.

Findings

A total of 1,382 engagements were recorded across all sectors over seven months. The most frequently identified high impact partners were federal and Puerto Rican governmental organizations partners. NGOs and nonprofits were noted as key partners in obtaining community perspective. Sector teams cited a lack of trust and difficulty identifying partners as barriers to partner engagement. Given the expedited nature of disaster response, establishing partnerships before disasters occur may help facilitate community input. Early networking, increased transparency and defining roles and responsibilities may increase trust and effectiveness among partnerships.

Originality/value

To our knowledge, this is one of the few studies that quantifies and illustrates the partnerships formed and their contributions during recovery planning, and lessons learned.
