算法的相关性变换与划分带个数的关系

使用相关性变换法，划分并映射循环算法到具有固定尺寸的Ｓｙｓｔｏｌｉｃ阵列。下标集合被划分成若干条带，划分带的条数与变换后的Ｓｙｓｔｏｌｉｃ阵列算法的执行时间成正比。指出了Ｍｏｌｄｏｖａｎ给出的计算划分带条数的公式有很大局限性，给出了由空间变换计算划分带条数的方法。

SCHEDULING PROBLEMS - AN OVERVIEW

There seems to be a significant gap between the theoretical and the practical aspects of scheduling problems in the job shop environment. Theoretically, scheduling systems are designed on the basis of an optimum approach to the scheduling model. However in the practice, the optimum that is built into the scheduling applications seems to face some challenges when dealing with the dynamic character of a scheduling system, for instance machine breakdown or change of orders. Scheduling systems have become quite complex in the past few years. Competitive business environments and shorter product life cycles are the imminent challenges being faced by many companies these days. These challenges push companies to anticipate a demand driven supply chain in their business environment. A demand-driven supply chain incorporates the customer view into the supply chain processes. As a consequence of this, scheduling as a core process of the demand-driven supply chain must also reflect the customer view. In addition,
