Closed Loop Supply Chain (CLSC) is growing due to environmental concerns, laws requiring product recycling, and rising consumer awareness. Original Equipment Manufacturers (OEMs) are increasingly participating in CLSC through remanufacturing, which costs less than making new products because it uses less material and energy. For example, remanufacturing can save 25.9% in energy compared to producing new items and could annually save the mobile phone industry $1 billion in raw material costs if 95% of phones were remanufactured.
　　This cost advantage allows companies to sell remanufactured products for up to 40% less while earning 20% higher profit margins than new products. Leading firms like IBM, Huawei, Svolt Energy, and Caterpillar see the potential in remanufacturing and are actively involved. However, remanufacturing is complex and labor-intensive, making it challenging to handle returned products.
　　OEMs must decide whether to enter the remanufacturing market, considering competition from independent remanufacturers (IRs) who specialize in end-of-life products. IRs' remanufactured goods compete directly with new OEM offerings, prompting OEMs to carefully choose market strategies and pricing to maximize profits.
　　It is worth proposing a new pricing strategy for OEMs managing different versions of new and remanufactured products within CLSC considering the different prices for different versions of products. It takes into account consumer demand influenced by price and product reusability, using the Salop spatial model to analyze substitution effects among different versions.
　　By exploring optimal reusability levels and comparing OEM-made and IR-made remanufactured goods, the study provides analytical models to guide OEMs in strategic decisions regarding remanufacturing and pricing. It considers competitive market dynamics and consumer preferences for specific product features, aiming to enhance decision-making in CLSC environments. 　　

(一) 嘉里大榮物流 　　撰文/朱語喬 　　課程：「物流管理」
　　為加深修課同學對物流的理解，我們乘車到位於桃園市龜山區頂湖路的嘉里大榮物流參訪。嘉里大榮的營業項目廣泛，包括快遞服務、常溫倉儲、低溫配送、醫藥物流等核心項目。
　　此次參訪，學習了低溫倉儲和常溫倉儲的布置與運作。一進入低溫倉儲內，就看到穿著防寒衣物的職員。員工需做好防寒措施，才能在負十八度的倉庫中工作。員工可透過機器查詢貨物的位置，駕駛堆高機搬運貨物。我們還參觀了負責配送NB的常溫倉儲，同學們體驗了揀貨與上架貨品。令人印象深刻的場景是AGV從一排排貨架中抬起目標貨架，將貨架搬運至揀貨員面前。AGV的行動非常穩定，電量低於設定標準時會自行至充電站充電。
　　經過這次校外參訪，不僅對物流的工作流程了解的更深，還見識了自動倉儲系統，讓人大開眼界。希望學弟妹也有機會透過這樣的方式增廣見聞，學習更多實務經驗。
(二) 衛生福利部桃園醫院 　　撰文/鄧如媛 　　課程：「醫療品質管理」
　　這學期的醫療品質管理課程，老師為了讓同學更知悉品管是如何運用醫療之上，安排桃園醫院的校外參訪，這次經驗不僅增加了對醫療行業的尊重，也激發了對未來職業生涯的期待和準備。
　　首先去到檢驗科，經由主任講師的解說介紹看了實驗室裡的動線及各站點，發現科室有引進法國實驗室自動化系統暨實驗室專家系統，能大幅提升檢驗之效率及品質，接著參觀2樓各科動線和狀態，10樓腦中風單位以及病房的設施規劃，再去到1樓領藥櫃檯。現在全面機台自動化，掛號採取插健保卡即病人辨識，等待時間可省略許多。
　　參訪醫院是一個深刻的學習經驗，經由這次的活動，讓同學們對醫療環境有了更全面的了解。從觀察日常運作到與醫護人員的互動，每一個細節都能提供寶貴的見解，讓大家對醫療品質管理瞭解更深，能親眼目睹寫醫學自動化實驗室是件難能可貴的事，徹底理解品管無所不在，在醫療領域上也能有效的提升醫院整體服務及醫療水準。 　　   

1. Giri, Sanju Kumar吉瑞(印度)：
      I am incredibly grateful to the Taiwan Scholarships (MOE) for giving me the amazing chance to study at Yuan Ze University, Taiwan. As a student in the top-ranked IEM department, I've learned so many valuable skills, from industrial engineering to project management, thanks to some of the best professors in their fields. Their constant encouragement pushed me to exceed my limits, helping me secure the top rank in my department for Fall 2022-2023, and placing me in the top 3% of master's students, which earned me the Phi Tau Phi honorary society award. These past two years have truly transformed my life, revealing my potential to achieve even more. I am forever thankful to the Yuan Ze University family, especially my IEM department, and the Taiwan Scholarships for their unwavering support. I wouldn't be who I am today without them.

2. Rizal Justian Setiawan羅扎拉(印尼)：
      During my studies in Industrial Engineering and Management (IEM) at Yuan Ze University (YZU), I took 12 courses. The courses provided at IEM YZU are the courses I need because they are closely related to industrial engineering and management, including related to business, system control, programming, scheduling, and project management. The quality of Professors is also excellent, they use full English when teaching and provide useful assignments for students. Additionally, courses are designed to be relevant to current industry trends and needs, ensuring students learn applicable and in-demand skills. I had good and high grades while studying at IEM YZU, all the lessons I got from the course helped me create many papers to be published in journals and to join international conferences. During almost 2 years at IEM YZU, I already published 6 journal papers and participated in 5 international conferences in 5 countries.
      I recommend engineering graduates from all over the world to study Industrial Engineering and Management (IEM) at Yuan Ze University (YZU) because during my experience here this study program has a curriculum that balances technical engineering skills with management and business knowledge, preparing students for diverse career paths. In my opinion, IEM YZU is designed to provide a well-rounded education with ample opportunities for practical experience, research, and professional development, making it a strong choice for aspiring engineers and managers. At IEM YZU, there are also many international students, this is a good atmosphere to study globally. The ICDF Manager at IEM YZU (Mrs. Peggy) is also very fluent in English, there were no obstacles when communicating with her, she always helped us and gave us a lot of insight.
