A strategic planning model for the railway system accident rescue problem

The present study examines the location of emergency rescue problems for urban ambulance and railway emergency systems. The proposed model considers probabilistic rescue demand, independent busy fractions of ambulances, and the corresponding risk levels in railway segments. We formulate the proposed model using fuzzy multi-objective programming and solve it using a generic algorithm and a non-dominated sorting genetic algorithm-II. Computation results are analyzed by applying the model to a real-world Taiwan railway system. Analytical results demonstrate that a proper adjustment of the rescue resource location improves rescue effectiveness for railway rescue and urban medical service demand.

Classifying railway stations for strategic transport and land use planning: Context matters!

The classification of railway stations is a potentially powerful tool for strategic transport and land use planning. Existing classifications rely strongly on the indicator “passenger frequency”, which focuses on transport related issues, blending performance with preconditions at a given site. We argue that a classification system for strategic planning should focus on the demands and conditions of the site within which the railway station must function, i.e. system context. Here, we present such a classification system: a cluster analysis of the 1700 Swiss railway stations relying solely on context factors. The resulting classes vary primarily in density (of land use and transport services) and use (commuting, leisure time, tourism). Common geographic patterns and class-specific dynamics are discernable. These results indicate that classification based on the relevant demands and conditions given by context leads to clearly interpretable classes and supports multi-perspective strategic planning for railway stations. The systematic approach allows for a better understanding of the interrelations between railway stations and their context.     

Policy-sensitive selection and phasing of road investments with a goal program

A goal program to select and schedule road projects can include policy considerations in addition to those covered by cost-benefit evaluation. Five economic benefits and twelve environmental, developmental and accessibility objectives constitute the goals in a rural application in Western Australia. A plan and construction schedule can be generated for any set of priorities, each satisfying the budget constraint. Government can choose from them to match current policy concerns and meet the needs of affected residents. The method is particularly valuable when there are linkages between projects.     

A robust hybrid decision model for evaluation and selection of the strategic alliance partner in the airline industry

Owing to the cut throat competition and economic uncertainty in the market, airlines are focusing on strategic alliances for satisfying customer needs, especially in the current time which is dominated by global integration, demanding customer and fast changing technologies. This strategy is widely adopted by airlines. However, the selection of strategic alliance partner is a very decisive decision, and this selection process engrosses a number of complex processes which is result of compound reflection of associated various factors. In addition, the decision makers may be inconsistent in their views and preferences, arising due to imperfect information or intrinsic conflict between various departments. This paper presents a model based approach of an analytic hierarchy process (AHP) for evaluation of criteria and fuzzy technique for order performance by similarity to ideal solution (FTOPSIS) for the selection of strategic alliance partner. A case of Indian airline industry demonstrates the application of the proposed approach. Eventually, robustness of the model is demonstrated by sensitivity analysis.     

Modeling downstream petroleum supply chain: The importance of multi-mode transportation to strategic planning

This paper proposes a deterministic mixed integer linear programming (MILP) model for downstream petroleum supply chain (PSC) network to determine the optimal distribution center (DC) locations, capacities, transportation modes, and transfer volumes. The model minimizes multi-echelon multi-product cost along the refineries, distribution centers, transportation modes and demand nodes. The relationship between strategic planning and multimodal transportation is further elucidated. A case study was considered with real data from the U.S. petroleum industry and transportation networks within Geographic Information System (GIS). A scenario analysis is also conducted to demonstrate the impact of key parameters on PSC decisions and total cost.     

Spatial structure and network behaviour of strategic airline groups: A comparison between Europe and the United States

The Gini-index has gained in legitimacy when measuring traffic distributions of air traffic as compared to other more established measures, such as Herfindahl's. In order to render the index more meaningful for policy-makers, a partial decomposition into strategic groups of airlines along distinct geopolitical scopes of air traffic is suggested. Air traffic across airports is considered an aggregate of complex networks that are subject to multiple constraints, such as geopolitics or technology. A multi-layered analytic approach accounts for network operators as economic agents that behave in strategic ways within these constraints. Our approach allows for comparing traffic distributions in Europe with that of the US and, in particular, introduces a normative component by isolating patterns in airlines’ strategies that are likely to induce different degrees of spatial concentration and balanced traffic distributions within these common markets.     

Models of crisis management: an evaluation of their value for strategic planning in the international travel industry

Tourism is particularly prone to external shocks, which by their nature are unpredictable and need to be addressed through effective crisis management processes. The paper reviews the literature relating to crisis management in tourism and identifies and briefly critiques several models that have been developed to help managers in their strategic planning for such contingencies. The terrorist attacks of ‘9/11’ are used as an exemplar of the type of external shock that can lead to crisis if travel industry managers fail to take immediate and decisive action. This paper discusses the reactions of leading UK based tour operators to the terrorist attacks and a case study is presented to examine the reaction of a particular company to ‘9/11’ and to review the ‘turnaround’ strategies used. The crisis management process model is compared and contrasted with the steps actually undertaken at the company. It is evident that there are wider lessons for the travel industry including the need to: integrate crisis management with strategic planning processes, prepare detailed contingency plans, define decisional roles and responsibilities, and to retain a degree of flexibility.

Evolution of global airline strategic alliance and consolidation in the twenty-first century

Global airline strategic alliances have emerged since the late 1980s, and their number has slowly risen through the years. Will the number of such alliances continue to proliferate? Or will airlines consolidate with one another to form mega-carriers? In this paper, the likelihood of various airline consolidation and alliance development possibilities was examined based on a number of high-level trends and forces. The most probable near-term industry alliance and consolidation structure is described, accompanied with a probable path of evolution. These predictions have important implications for managers of strategic alliances, carriers who are currently in an alliance as well as carriers who are planning to join one.     

How company and managerial characteristics influence strategic alliance adoption in the travel sector

The purpose of this paper is to examine the role of company and executive characteristics in strategic alliance formation in the tourism sector of travel. A survey of Australian travel sector businesses was carried out and the results indicate a high level of interaction through alliances between various sectors of the Australian tourism industry. Top managers' characteristics (experience, ownership and risk‐taking attitude) were found to be influential in taking strategic decisions of whether to form alliances or not. These characteristics do not play an important role in determining the number of alliances an organisation has and their geographical location, as much as company characteristics do. The findings of this paper imply that company characteristics are important in determining alliance formation. Managers should thoroughly consider these characteristics when deciding not only to form alliances, but also the types of alliances that could help their organisations to be more competitive, given limited resources.
