摘要：We study a scheduling problem with changeover costs and capacity constraints. The problem is NP-complete, and combinatorial algorithms for solving it have not performed well. We identify a general class of facets that subsumed as special cases some known facets from the literature. We also develop a cutting-plane-based procedure and reformulation for the problem, and we obtain optimal solutions to problem instances with up to 600 integer variables without resorting to branch-and-bound procedur...

摘要：Revenue management has become an important tool in the airline, hotel. and rental car industries. We describe asymptotic propertied of revenue management policies derived from the solution of a deterministic optimization problem. Our primary results state that, within a stochastic and dynamic framework, solutions arising out of a single well-known linear program can be used to generate allocation policies for which the normalized revenue converges in distribution to a constant upper bound on t...

摘要：Some problems in economics. operations research, and engineering may be approached by means of a pair of radial DEA models that are nested, i.e., that the set of Constraints of one of them is included in that of the other, In this paper we have focused on analyzing the marginal role of a given variable, called candidate. with respect to the efficiency measured by means of a DEA model, First, we have defined a new efficiency contribution measure (ECM), which finally compares the efficiency scor...

摘要：This paper is concerned with the performance of multicommodity capacitated networks in a deterministic but time-dependent environment. For a given time-dependent origin-destination table, this paper asks if it is easy to find a way of regulating the input flows into the network to avoid queues from growing internally, i.e., to avoid capacity violations. Problems of this tape are conventionally approached in the traffic/transportation field with variational methods such as control theory (if ti...
