Comprehensive Experiment Design of Production Logistics Based on CDIO Ying-de Li, Xiu-ju Lan Mechanical Engineering College, Zhejiang University of Technology (liyingde2008@sina.com) Abstract - Production logistics engineer in manufacturing plant is one of the important potential employments for logistics engineering students. The training purpose of our school is to provide some professionals who are familiar with the production logistics and from the logistics engineering graduates. Based on the CDIO concept, a comprehensive experiment is designed, which include the production forecasts and orders issued, facilities planning, production line design, production planning and scheduling, quality control and analysis, just in time and material distribution, to simulate the production logistics in the typical manufacturing factory. We will put forward the experiment design, group and role allocation, experiment procedures, experiment result analysis, the effect evaluation and improvement and so on. Key words - CDIO concept, production logistics, comprehensive and project-based experiment, role exchange I. Analysis of teaching problems Production and Operation Management, Facilities Planning and Logistics are the important courses for the students whose major is the Logistics Engineering, the core contents of the two courses are closely related to actual operation of enterprises (especially the manufacturing plants) and are the core curriculum to cultivate production logistics professional[1]. The two courses cover the market demand analysis, facilities planning and layout, logistics systems analysis and design, organization and design of flow line, production planning and control, quality control, work study and time study, business process reengineering, advanced manufacturing systems and so on, which have strong practical[2,3]. Among the many interesting facts we know about how experiences affect learning, one relates especially to CDIO[4]: Engineering students tend to learn by experiencing the concrete and then applying that experience to the abstract. Unlike their counterparts of yesteryear, many engineering students these days don’t arrive at college armed with hands-on experiences like tinkering with cars or building radio [5,6]. CDIO has open and accessible channels for the program materials and for disseminating and exchanging resources. CDIO collaborators have assembled a unique development team of curriculum, teaching and learning, assessment, design and build, and communications professionals. They are helping others to explore adopting CDIO in their institutions[7]. Current teaching model pays more attention on the basic theory[8,9], the teacher mainly use the lecture notes, the students are accepted the basic knowledge passively. It is lack of comprehensive, systematic experiment course, teachers and students are lack of communication deeply, the students are lack of real feeling to the knowledge, it is difficult to achieve the teaching effectiveness. Although the teacher use some auxiliary teaching material and tools[11,12,13], such as cases study, video explore, basic understanding of practice, there are some problems in teaching model, which include as follows: (1)In case study, there are some descriptive content, but there are lack of actual data, the case is far away from the practices, which is hard to attract the students interesting. (2)The comprehensive video is lack of production logistics, the special subject of production logistics is lack, it is difficult to integrate the curriculum content closely. (3)The understanding of the practice is too short a, it is difficult for students to understand the application of professional knowledge deeply. The existing curriculum design is limited to theoretical and lack of practices supporting. (4)The experiment teaching software pay more attention on the solution of the model of production and management activities, not on the production logistics analysis which is play more roles on culturing. It is hard to achieve the teaching purpose which is to culture the applying and innovative ability. (5)The knowledge and emotional experience of juniors are far away from the actual business operation, with the abstraction and boring the course knowledge, which lead to the lack of study interesting for students. In response to these problems, it is necessary to design a comprehensive experiment on the logistics engineering and industrial engineering laboratory platform based on the CDIO engineering education philosophy[14]. The comprehensive experiment will integrate many courses to improve the understanding and application to the organization, design, operation and control for the production logistics in manufacturing factory[15]. The comprehensive experiment can attract the interesting in professional courses. II. Experiment objectives design The experiment purpose is to help the students to learn how to use the theory knowledge comprehensively. The experiment will provide a production process model by independent design, analysis and optimization for students to cultivate the independent analysis and problem-solving ability. The detail objectives include as follows: (1)To change the single teaching method and improve the teaching effectiveness, which can improve the application of CDIO concept in the high education; (2)To help the students to understand the production and operation in manufacturing enterprises deeply, to improve the understanding on basic theory and methods in courses, to reduce abstraction and boring feeling, and to attract the study interesting; (3)To improve the recognize, understanding and application to the internal production logistics system of manufacturing plant, to enhance recognize and interesting on the production logistics jobs, to broaden the employment view and choice; (4)To improve the application ability to solve practical problems with comprehensive knowledge, and to culture the creativity and teamwork ability. III. Experiment syllabus design A.CDIO concept and philosophy Engineering education and real-world demands on engineers have in recent years drifted apart. Realizing that this widening gap must be closed, leading engineering schools in the USA, Europe, Canada, UK, Africa, Asia, and New Zealand formed the CDIO Initiative: A worldwide collaborative to conceive and develop a new vision of engineering education[1]. CDIO is an initialism for Conceive-Design-Implement -Operate, which is an innovative educational framework for producing the next generation of engineers. The framework provides students with an education stressing engineering fundamentals set in the context of Conceiving -Designing-Implementing-Operating real-world systems and products [6,7]. Throughout the world, CDIO Initiative collaborators have adopted CDIO as the framework of their curricular planning and outcome-based assessment. The CDIO concept was originally conceived at the Massachusetts Institute of Technology in the late 1990's. In 2000, MIT in collaboration with three Swedish universities (i.e. Chalmers University of Technology, Linköping University and the Royal Institute of Technology) formally founded the CDIO Initiative. It became an international collaboration, with universities around the world adopting the same framework. CDIO collaborators recognize that an engineering education is acquired over a long period and in a variety of institutions, and that educators in all parts of this spectrum can learn from practice elsewhere. The CDIO network therefore welcomes members in a diverse range of institutions ranging from research-led internationally acclaimed universities to local colleges dedicated to providing students with their initial grounding in engineering. The CDIO Initiative is rich with student projects complemented by internships in industry, features active group learning experiences in both classrooms and in modern learning workshops/ laboratories, and rigorous assessment and evaluation processes. The CDIO Initiative’s goals are to educate students to master a deeper working knowledge of the technical fundamentals, to educate engineers to lead in the creation and operation of new products and, to educate future researchers to understand the importance and strategic value of their work. The collaborators maintain a dialogue about what works and what doesn't and continue to refine the project. Determining additional members of the collaboration is a selective process managed a Council comprising original members and early adopters. B. Experiment syllabus Under the CDIO teaching concept, experiment includes many professional courses, relevant principles and theories, which includes the production demand analysis and forecast, facility planning and layout, flow line organization and balancing, through output analysis, production planning and schedule, quality control and statistical analysis, Just in Time system, Kanban system and so on. The experiment syllabus includes: (1)To master the market demand analysis and forecast; to understand the JIT production model; to grasp the basic production planning methods and production analysis methods. (2) To familiar with the general methods of facility planning and layout, to use these methods to analyze the production logistics system; and to know well the logistics equipment and the basic process of internal logistics and so on. (3)To grasp the assembly line design and balancing method, know well about the application of line balancing software and tools; to use the general standard time method and tools; to understand the important role of the assembly line organization and management in manufacturing system. (4) To master the common tools and statistical software in quality control and analysis; to understand the impact on the production of the quality fluctuations; to understand the basic quality management knowledge and concepts, such as the qualified rate, sample testing, passthrough rate, rework rate, downgrade management and so on. (5)To understand the organization, design, operation and control system in manufacturing plant, to improve the interesting in study; to help students to grasp the core operation process of manufacturing plants comprehensively and systematically. IV. Experimental instructions A. Experiment roles The experiment includes the background and roles design and setting. The experiment background is a children toys manufacturing plant, which has complete organization, flexible assembly lines and production facilities, the production mode is the JIT system. The third parts supplier can provide all the materials in the BOM. There are 7 roles, including one teacher and 10 students (the ID is from S1 to S10), the initial roles setting is in the Table 1. B. Experiment procedure Role Customer Actor Teacher Market S1 Production planning S2 Assembly line S3~S7 Material Supplier Distribution S8 S9 Quality S10 The comprehensive experiment procedure flow is shown in the figure 1 and the detailed procedure is shown in the Table 2. TABLE 1 Experiment roles Responsibility supplying the demand information dynamitic and negotiate with the manufacturer Team leader, Collect the market demand information, capacity analysis and confirm the orders; organize production meeting and record the production data; responsible for the production process design and implementation. According to orders and production conditions, draw up the production planning tasks, track and adjust the production schedule in real-time. Student 3,4 and 5 are responsible for assembly tasks, Student 6 and 7 are responsible for the take-apart task. The allocation can be adjusted dynamically based on the orders. Responsible for the material supply based on the JIT and Kanban model. Optimize the delivery route and the products and disassembled parts distribution.

CDIO Group and role allocation Basic theory teacher team Orders Demand analysis teacher Flow line organization and balancing Material supply Capacity analysis Production planing team Team 2 times Role reallocation Summary improvement third time Execution at lab Team and teacher teacher Fig.1 The produce flow of the experiment Step Step 1 (2 hours) Step 2 (2 hours) Step 3 ( 6 hours) Step 4 (2 hours) TABLE 2 Experiment detail steps Tasks Introduce the experiment theory, principle, procedures, tasks; students ask questions; Students are divided into three groups ,each group includes 10 students, set the role for each student; Teachers provide the production data and orders; Students discuss and decide whether or not to take the orders; the team leader will allocate the tasks among the team to fulfill the order-demand. Group take the production preparation meeting to analysis the capacity and draw up the detailed production planning, finally, publish the task to the assembly line. Change the laboratory layout based on the demand. After receiving the production task, assembly group put forward the layout and organization, including task assignment, balancing, material supply, product distribution. Suppliers give the materials supply planning to ensure the operation; Distributor explore the product distribution planning. Do the experiment at the lab. First time, the teacher will participate the whole process an give some advice on-site, students will fulfill the experiment independently at the second and third time. The team leader (S1) is responsible for the organization. Each student should be responsible to the team leader ,and complete their own tasks. The above three steps are repeated three times, the group members can change the role ate each experiment based on their interests and practice. The difficulty will be improved gradually. Summary the experience and communication; Hand in the report document, show the PPT, do some experience exchangement; Give some advices to improve the experiment; Teacher reviews and scores each group and each student. C. Experiment implementation Experiment goes into the teaching guideline as an independent course; the experiment needs 12 hours totally, with group exchange model to allocate the time. For example, there are about 30 students in the Logistics Engineering classes, all the students can be divided into three groups, and there are 10 members in each group. Each group needs two hours in the laboratory, this procedure will repeat three times for each group. The role setting can be exchanged at each time based on the needs and interesting. The difficulty will increase gradually. V. Conclusion We do some tests in the class Logistics Engineering 2008 at Zhejiang University of technology from September 2011 to December 2011. The results show that we have made a perfect improvement on teaching; the single teaching method has been changed. The students generally reflected that they understand of the basic theory through project-based experiments deeply, their interesting to study have been increased greatly. They learned the practice knowledge and the horizons of employment have been broadened greatly. Comprehensive experiment course achieved a perfect teaching effectiveness and teaching evaluation, the total score was 98.73, the teaching resources index, teaching content index, teaching methods index, teaching effectiveness index and teaching services index were 9.85,9.88,9.87,9.85 and 9.88 respectively.
