This article considers tour route planning problems to find an optimal tour route in sightseeing. Tour routes are optimized in terms of two types of criteria. The first optimization criterion is to maximize the sum of values of places a tourist visits, namely, the sum of the values of sightseeing spots, restaurants and hotels. The second optimization criterion is to minimize the tiredness caused by...
This paper proposes a personal tour planning problem incorporating general tour routes and tourists satisfactions for sightseeing places based on some purposes of tourism. In order to construct a tour route, time-dependent satisfactions, traveling and activity duration times for sightseeing should be considered, but it is difficult to represent the time-dependent model using general static network...
This paper proposes a personal tour planning problem with uncertain traveling times and satisfaction values of sightseeing places dependent on sightseeing. Since traveling times are dependent on the time of day, it is difficult to represent this uncertain model using the general static network model. In this paper, Time-Expanded Network (TEN), which contains a copy to the set of nodes in the underlying...
This article considers multiobjective linear programming problems (MOLPP) where random fuzzy variables are contained in objective functions and constraints. The purpose of the proposed decision making model is to optimize values at risk under the constraints using a necessity measure. An interacitve algorithm is constructed in order to obtain a satisficing solution for the decision maker from among...
