A Task-oriented Modular and Agent-based Collaborative Design Mechanism for Distributed Product Development

The rapid expansion of enterprises makes product collaborative design （PCD） a critical issue under the distributed heterogeneous environment, but as the collaborative task of large-scale network becomes more complicated, neither unified task decomposition and allocation methodology nor Agent-based network management platform can satisfy the increasing demands. In this paper, to meet requirements of PCD for distributed product development, a collaborative design mechanism based on the thought of modularity and the Agent technology is presented. First, the top-down 4-tier process model based on task-oriented modular and Agent is constructed for PCD after analyzing the mapping relationships between requirements and functions in the collaborative design. Second, on basis of sub-task decomposition for PCD based on a mixed method, the mathematic model of task-oriented modular based on multi-objective optimization is established to maximize the module cohesion degree and minimize the module coupling degree, while considering the module executable degree as a restriction. The mathematic model is optimized and simulated by the modified PSO, and the decomposed modules are obtained. Finally, the Agent structure model for collaborative design is put forward, and the optimism matching Agents are selected by using similarity algorithm to implement different task-modules by the integrated reasoning and decision-making mechanism with the behavioral model of collaborative design Agents. With the results of experimental studies for automobile collaborative design, the feasibility and efficiency of this methodology of task-oriented modular and Agent-based collaborative design in the distributed heterogeneous environment are verified. On this basis, an integrative automobile collaborative R＆D platform is developed. This research provides an effective platform for automobile manufacturing enterprises to achieve PCD, and helps to promote product numeralization collaborative R＆D and management development.

The Exploration of Task Design in Online Class——Taking“New Horizon College English”and Chaoxing Learning Platform as Teaching Aids

As a long-term or short-term teaching method in response to“public health emergencies”,online teaching is the mode that college teachers must be competent.Integrating scientific pedagogical concepts into full-time online classes can fully take advantages of the characteristics of online courses and continue to create high-level,innovative and challenging courses.The creation of real situations in the task design of college English not only focuses on cultivating learners’ability to actively construct knowledge,but also conforms to the laws of students’physical and mental development,as well as stimulates their learning motivation.Critical reading teaching carried out under the flipped-class mode,supported by network information technology and massive resources,helps students develop independent learning capabilities,solve complex problems,and expand critical thinking.As an indispensable model in college education,online teaching is to be developed,and there is still more room for research on the principles and paradigms of online course design.

A Study on the Design of Task Activity in the Post- task Stage of Middle School English Classroom

The task activity in the post-task stage is mainly to enable the students clearly aware of their own language learning process in the existing problems and effectively solve them through the ＂do-it-again＂ , language focus and other activities, and at the same time the focus of this lesson, difficulties are more clear and clear. It can be said that post-task activities play a vital role in highlighting priorities, breaking through difficulties, and achieving effective goals for teaching goals. The design of the activities in the post-task stage is to complete the task and language focus together, reflecting the distinctive characteristics of task-based teaching. The design of the activities in the post-task stage can be achieved through evaluation, language focus, and extra-curricular activities.

Task Design of Task-Based Language Teaching in College English - A Case Study on Criticism: Don’t Take It Personally

Task-based language teaching(TBLT)is a new English teaching method,in which teachers design specific tasks before classes,and students then acquire knowledge as well as develop their communicative competence and English proficiency by completing these tasks in class.In the whole process,the most important thing is task design in that it will directly affect the implementation and effect of TBLT if the teacher is unable to handle the task design properly.This paper aims to discuss on how to design better tasks to achieve the objective of helping students develop their communicative competence by taking Text A(Criticism:Don’t Take It Personally)of Unit 7(Interpersonal Relationships)in the 21st Century Practical College English(Book 2)as an example under the concept of TBLT.

The Definition of Task in Task-Based Language Teaching and The Factors Considered in Task Design

Task-based language teaching(TBLT)has caused considerable interests among curriculum developers,language testers and language teachers during the past several decades.In order to use the approach rightly,throughout literature review,the essay is going to analyze what the task is critically and the factors teachers should consider when they design tasks.At the end of the study,it is concluded that even though the definition of task is various,the main criteria are that a task is mainly focusing on meaning;has a clear goal;involves the outcome;and is related to the real world.When design tasks,teachers need to balance the fluency,accuracy and complexity,making task difficulties be appropriate to students’levels,considering thematic content and the range of task types and the phases of tasks.
