查询词典 problems

All the sub-plans are described by a group of general mathematic formulae. The computation of the sub- plan can be decomposed into two sub-problems by relaxing the constraint that production level at production period of a sub-plan must be more than zero. Based on the properties of an optimal solution, two polynomial algorithms are devised to solve sub-problems and reintegrate the relaxed constraint. Finally, a dynamic programming algorithm with complexity O(T^4) is developed to solve the global problem, where T is number of periods in planning horizon.

给出了所有子计划的通用数学描述，并通过松弛正生产量约束将子计划的计算分成两个子问题；依据子问题和子计划最优解的性质，设计了求解子问题和重新集结松弛约束的多项式算法；在此基础上提出了一个复杂性为O(T^4)的求解整个规划问题的多项式动态规划算法，这里T是规划时段上的周期数。

The event-tree based modeling and optimization algorithms are adopted and the whole problem is divided into two sub problems (the portside sub problem and the refinery sub problem).Thus, the algorithm is proposed by analyzing the solving sequence of the two sub problems.

According to the J.D. Power Initial Quality Study－which measures product quality using a metric called "PP100," or problems per 100 vehicles－China's industry average PP100 rating stands at 231, or almost twice the U.S. average of 124. And among domestic Chinese brands, quality problems are almost twice as frequent as in locally built international brands （an average of 368 PP100 for domestic brands, compared with 189 for international brands）.
