The classical newsvendor problem is restudied under the perspective of competitive analysis in this paper. Unlike the approach of probabilistic analysis which may give some solutions that are far from the optimal solutions under some scenarios, competitive analysis provides very robust statements about the performance of an online solution, against all possible scenarios. With detailed competitive...
After analyzing the bidding tactics decision-making index system for BOT projects, the bidding tactics decision-making method is presented by wavelet network learning algorithm based on conjugate gradient method, the decision-making model is set up. The paper bring forward the problem solving method to the above model by optimizing and select the hidden units of wavelet network. An instance is given...
Based on the traditional Ski-Rental Problem, an ongoing decision-making problem in our everyday life, namely the travelerpsilas waiting problem, is studied in this paper. The realistic background of the problem is that a traveler's decision on whether he should wait for a bus with uncertain arriving time. Three approaches for decision-making with incomplete information, i.e. worst-case competitive...
Concurrency control is one of the key factors in computer supported cooperative work. Through researching conflict of concurrency control mechanism and CSCW, this paper introduces the rough set into the conflict-detection, and forms a new algorithm idea. Also, the paper analysis the feasibility of the new algorithm and gives an example.
Association rule mining is concerned with the discovery of interesting association relationships hidden in databases. Traditional algorithms are only considering the constraints of minimum support and minimum confidence. However, sometimes it is essential to find stronger association rules for decision makers possessing inadequate resources, and sometimes less strong rules are needed. In this paper,...
The Bahncard problem is a generalization of the Ski-Rental problem. Previous research approaches on the Bahncard problem have mostly focused on the "pure" competitive analysis that "deliberately" ignores all available information. Fleischer presented a deterministic (2-beta)-competitive online algorithm and showed that this is the best competitiveness of a deterministic strategy...
