A theoretical planning model and training system of skill acquisition for setup operation

加工前的设置操作非常复杂，现在主要依靠工人的经验。因此，通过反复有效的培训，提高安装操作技能，成为几乎所有工人的重要任务之一。为了评估设置技能，考虑了技能获取模型。该模型具有两种特征：一种是静态模型，即技能习得的基本模型；另一种是受同伴技能影响的动态模型。通过这两种模型，非技术工人的培训计划可以朝着技能目标实施。明确技能获取过程的程序包括以下步骤。在第一步中，首先由一个非技术工人执行安装操作。将非熟练工人的训练结果与计算机计算的最优解进行比较，并在第二步进行评价。然后，对一个非技术工人进行重复培训，直到他的评估接近最优解决方案的水平。因此，显示他对最优解的评价的连续轨迹的轨迹被表示为技能训练的函数。此外，还需要技能培训功能的动态修正系统来管理单个培训中的设置操作技能水平。对于非技术工人来说，在非技术工人的团队合作的基础上进行团队培训是很重要的。团队培训，特别是任何两个非技术工人的合作培训，被认为是制造业教育的一种技能策略。该系统可作为技能培训系统，用于提高非熟练工人的安装技能。

The setup operations before machining are much complicated, and it is now depending on worker's experience. Hence, it becomes one of important missions for almost workers to enhance the skill of setup operations by repeating the effective training. In order to evaluate the skill of setup, the skill acquisition model was considered. This model had two characteristics : a static type which is a basic model of skill acquisition, and a dynamic type which is influenced by the skill of partner. With two proposed model the training plan of unskilled workers could be implementation towards the goal of skills.The procedure making clear the skill acquisition process consists of the following steps. At first step, the setup operations by an unskilled worker were first implemented. The training result of an unskilled worker was compared with that of the optimum solution computed by a computer, and evaluated at second step. Then, the training for an unskilled worker was repeated until his evaluation would approach to the level of optimum solution. Hence, the trajectory showing the successive traces of his evaluation towards the optimum solution was represented as the function of skill training. Also, the dynamic revising system of skill training function was needed to manage the level of skill of setup operations in an individual training.It was important for unskilled workers to do a team training based on teamwork of unskilled workers. A team training, especially, a partnership training by any two-unskilled workers, was considered as one skill strategy for manufacturing education. This system was available as the skill training system for enhancing the setup skills for unskilled workers.
