This paper uses the Dominance-based Rough Set Approach (DRSA) to formulate airline service strategies by generating decision rules that model passenger preference for airline service quality. DRSA could help airlines eliminate some services associated with dispensable attributes without...

This study proposes a novel Forward Search and Backward Trace (FSBT) technique based on Rough Set Theory to improve data analysis and extend the scope of observations made from sample data to solve personal investment portfolio problems. Rough Set Theory mathematically classifies data into class...

Most multicriteria methods focus on ranking and selecting from a set of alternatives. These methods are usually used to compare all alternatives based on the synthesized scorings within a normalized scale with respect to the same criteria in multicriteria problems. However, the decision makers...

Taiwan lacks a natural energy endowment. Its energy demands have dramatically increased with the growth of the economy and standard of living during the past two decades. Based on the new socioeconomic developmentpolicy for the next two decades, the government of Taiwan has devoted special...

The world energy situation has been greatly influenced by the dramatic increase in world oil prices during the 1970s. To adjust to these increases, many countries have shifted to coal as a substitute for oil and have accelerated their research and development of renewable energy sources. Until...

As international corporate activities increase, the staffing of their operations involves more strategic concerns. However, foreign assignments have many differences, and dissatisfaction with host country is a known cause of expatriate failure. This study distinguishes from previous studies,...

Shortest-path (minimum travel time) routing has been adopted over the past few decades. However, many studies have shown that a driver's route and the shortest path differ widely in significant ways, and that most drivers use several criteria in selecting their routes. Since route choice...

Liner shipping companies can benefit significantly by improving ship scheduling and cost analysis in service route planning by systematic methods. This paper proposes a dynamic programming (DP) model for ship scheduling and identifies cost items relevant to the planning of a service route, which...

This article presents a new method for SElecting Non-independent TRansportation investment Alternatives (SENTRA). This method utilizes effective distance heuristic algorithm which attempts to maximize the achieved objectives needed to satisfy available resources. Since transportation investment...
