Among recent developments in the field of software reuse has been the increasing reuse of coarse-grained components, and it has been proved that granularity has great impact on component's reuse performance. However, previous studies have ignored rigorous and effective methods to support coarse-grained component identification and design, particularly(More)
A collaborative planning framework combining the Lagrangian relaxation method and genetic algorithms is developed to coordinate and optimize the production planning of the independent partners linked by material flows in multiple tier supply chains. Linking constraints and dependent demand constraints were added to the monolithic multi-level, multi-item(More)
With the trend of the worldwide market competition, the global agile manufacturing will becom an advanced manufacturing technology in 21st century, and the Agile Virtual Enterprise (AVE) will also become a new organization form of manufacturing enterprises. As AVE is a complicated enterprise, how to build an optimal AVE organization is a difficult problem.(More)
