We present novel branch-and-check and logic-based Benders decomposition techniques for the Travelling Purchaser Problem, an important optimization problem with applications in vehicle routing, logistics, and warehouse management. Our master problem determines a set of markets and directed travel arcs that satisfy product purchase constraints with relaxed travel costs. Our subproblem identifies ...
In [1] a feasible timetable generator stochastic simulation modeling framework for the train scheduling problem was developed to obtain a train timetable which includes train arrival and departure times at all visited stations and calculated average train travel time for all trains in the system. In this study, the framework is integrated with a genetic algorithm (GA) in order to get an optimal...
Directed flow loops are highly undesirable because they are associated with wastage of energy for maintaining them and entail big losses to the world economy. It is shown that directed flow loops may appear in networks even if the dispatched commodity does not physically travel along a closed contour. Consequently, a theorem giving the necessary and sufficient condition of a directed flow loop ...
The market for hotel and travel-related services can be seen as one in which the goods are differentiated products. Classification by the information content of goods – search goods, experience goods, post-experience goods and credence goods applies well to this market. Corrective measures are suggested for the market imperfections implied by asymmetry of information and transactions costs. Imp...
