Multi-objective optimization of process based on resource capability

To improve the practicability, suitability and accuracy of the trade-off among time, cost and quality of a process, a method based on resource capability is introduced. Through analyzing the relationship between an activity and its’ supporting resource, the model trades off the time, cost and quality by changing intensity of labor or changing the types of supporting resource or units of labor of resource in a certain time respectively according to the different types of its’ supporting resources. Through contrasting this method with the model of unit time cost corresponding to different quality levels and inter-related linear programming model of time, cost and quality for process optimizing, it is shown that this model does not only cover the above two models but also can describe some conditions the above two models can not express. The method supports to select different function to optimize a process according to different types of its supporting resource.

数学主题式学习教学实践与思考

设计跨学科学习主题并开展相应教学,以强化课程的协同育人功能,是新一轮课改的全新内容,在任务主题开发、教学实施中协同以及过程中的评价等方面尚存诸多困惑。以“制作活动日历”主题设计与教学为例,运用大学科视野,任务驱动;支持性资源,构建支架;表现性评价,引导认知迭代三条策略,从而在推进数学主题式学习过程中,提升学生综合素养,促进教师教学行为改变。
