摘要：We consider multimachine scheduling problems with earliness and tardiness costs. We first analyze problems in which the cost of a job is given by a general nondecreasing, convex function F of the absolute deviation of its completion time from a (common) unrestrictive due-date, and the objective is to minimize the sum of the costs incurred for all N jobs. (A special case to which considerable attention is given is the completion time variance problem.) We derive an easily computable lower bound...

摘要：The objective of the present study was to develop a comprehensive empirically-based model of the communication interface between R&D and marketing. Following Moenaert and Souder (1990), a causal model of the antecedents of information utility at the R&D/marketing-interface was postulated. A non-experimental critical incident method was used to test the model. The field survey involved 386 team members of 80 new product innovation teams in 40 companies. Path analysis was used to test the causal...
