Recent developments from the World Trade Organisation (WTO) and other international trade agreements have forced industries worldwide to face a new era of intense competition. The clothing industry sector, which has played a pivotal role in industrial development in Hong Kong, faces challenges from continued global economic restructuring and the accession of China to the WTO. Apparel manufacturers and trading firms need to review their competitive priorities and develop new business and manufacturing practices and strategies to compete. This paper presents the key findings of a recent study on the adoption of automation systems and strategy choices and discusses their relevance to the transformation of the apparel operations and businesses in Hong Kong. Two models namely, for integrated apparel business manufacture and for an apparel sourcing and coordination centre, are devised. 相似文献

Pluta microscope used to throw light on the effect of heat treatment time on the different properties of poly (ethylene terephthalate) PET fibers. PET fibers were annealed at times ranged from 5 to 30 min at different temperatures (150, 170, 190, 210°C) using two different processes (fast cooling and slow cooling processes) in air. The refractive indices, the shrinkage, orientation factor and crystallinity of PET fibers were determined for different annealing temperature during the short time treatment. The shrinkage percentage and degree of crystallinity increased with increasing the temperature and time of annealing. Microinterferograms are given for illustration. 相似文献

The automation and integration of manufacturing planning, scheduling and control functions have, for a long while, been targeted
in computer-integrated manufacturing (CIM) and artificial intelligence (AI) approaches. Current systems, however, are human-based
and they can only be characterised as decision support systems (DSS) rather than automated systems. Global competition and
the need for improved responsiveness, particularly in low-volume, high-variety manufacturing industries, necessitate further
integration and automation in planning, scheduling and control functions. We consider that, to achieve automation, the concepts
and techniques from operations research (OR), control theory (CT), and computer science (CS) should be integrated, enriched
and unified to provide a platform for automation. This paper presents a fresh perspective for understanding the design issues
involved and proposes a new framework for the automation and integration of planning, scheduling and control functions. A
fully automated flow shop production system is presented to illustrate the applicability of the new framework. 相似文献

近年来,多模式成像技术飞速发展。PET/MRI作为刚刚走入临床的多模式分子成像技术组合,成为医学分子影像领域的关注焦点,倍受期待。同机融合PET/MRI的出现依赖于PET和MRI系统各自的技术革新,以及基于MRI数据的衰减校正方法的完善。作为解剖、功能、代谢显像的综合体,PET/MRI较传统显像手段和其他成功的多模式成像技术,如PET/CT和SPECT/CT有更多、更新的应用优势,并已积累临床前和初步临床应用的经验。然而,正在走向商品化的PET/MRI仍有很多方面亟待改进和完善,需要通过不断发展、验证才能成为未来辅助临床诊断和指导治疗决策的有力工具。 相似文献
