天河CAPP系统的实施体会——CAPP扩展延伸功能解决思路

计算机辅助工艺规程设计(CAPP)在国内发展的较为成熟,目前绝大部分企业CAPP的应用停留在一般的基本功能方面,虽然有效地提高了工艺设计的效率和标准化水平,但应用的深度还不够,距离企业的实际需求还有差距。例如,作为CAPP灵魂的工艺编码在国内几乎看不到应用;如何转换历史工艺数据的格式,使其能够导入到CAPP系统中,这也是CAPP应用的难题。本文试图通过总结作者在组织天河CAPP在我公司实施过程中的体会,谈谈如何挖掘CAPP的潜在功能,使其更高效地服务于企业的工艺设计过程。

哈锅CAD与CAPP系统集成

自2000年8月31日哈锅与北京清华京喻天河软件公司结成企业信息化建设合作伙伴以来,两公司一直以“将哈锅打造成企业信息化应用典范”为目标;以“统一规划,分步实施”为CAPP项目实施方针,已扎扎实实的走过五个年头。这期间公司投入大量人力和财力进行公司信息化建设,建立光纤网在公司范围内连网,一期阶段的CAPP上不能承接设计CAD信息,下不能供生产部门、采购部门查询工艺信息,仍以纸面工艺文件的形式对车间指导生产。因此以CAPP为纽带,将CAPP与设计CAD集成及使下游部门能够利用CAPP信息成了公司信息化的关键。公司也接触过一些PD…

大恒CAPP介绍

CAPP计算机辅助工艺规程系统是制造业随CAD软件后的又一个应用重点,是一个非常有发展前景的软件产品。在国内提出CAPP设想不比CAD软件要迟,但应用的结果却大不相同。这主要是因为和CAD软件相比,CAPP软件的商品化工作要更难做一些。这不仅是因为CAPP系统从流程到工艺卡片的填写及汇总都没有一个固定的模式,而且要求软件开发商具有CAD图形处理和数据库应用这两方面的技术储备。因此,开发适用的、便于推广的CAPP软件对软件开发商来说是个挑战。大恒公司是国内著名的CAD软件供应商,有多年从事CAD软件开发和工程图纸管理系…

石油工程质量成本控制中的经济学思考

工程质量特性是满足甲方的要求，而质量的经济性应指质量成本最低时质量水平为最佳。传统的质量成本观有其一定的局限性．质量成本与质量损失构成质量会计两个重要的基本概念。开展工程质量成本控制，应做好质量成本预测、计划、核算、分析、考核和报告等工作。     

Implementing the lead user method in a high technology firm: A longitudinal study of intentions versus actions

The customer or user's role in the new product development process is limited or nonexistent in many high technology firms, despite evidence that suggests customers are frequently an excellent source for new product ideas with great market potential. This article examines the implementation of the Lead User method for gathering new product ideas from leading edge customers by an IT firm that had not previously done much customer research during their new product development efforts. This case study follows the decision‐makers of the firm through the process, where the end result is the generation of a number of useful product concepts. Besides the ideas generated, management at the firm is also impressed with the way the method makes their new product development process more cross‐functional and they plan to make it a part of their future new product development practices. Approximately one year later the firm is revisited to find out if the Lead User method has become a permanent part of their new product development process. The authors find, however, that the firm has abandoned research on the customer despite the fact that several of the lead‐user derived product concepts had been successfully implemented. Management explanations for their return to a technology push process for developing new products include personnel turnover and lack of time. Using organizational learning theory to examine the case, the authors suggest that the nontechnology specific product concepts generated by the lead users were seen as ambiguous and hence overly simplistic and less valuable by the new product development personnel. The technical language spoken by the new product personnel also increased the inertia of old technology push development process by making it more prestigious and comfortable to plan new products with their technology suppliers. The fact that the firm was doing well throughout this process also decreased the pressure to change from their established new product development routine. The implications for these finding are that: 1) it is necessary to pressure or reward personnel in order to make permanent changes to established routines, and 2) researchers should be careful at taking managers at their word when asking them about their future intentions.

Dancing robots: integrating art,music, and robotics in Singapore’s early childhood centers

In recent years, Singapore has increased its national emphasis on technology and engineering in early childhood education. Their newest initiative, the Playmaker Programme, has focused on teaching robotics and coding in preschool settings. Robotics offers a playful and collaborative way for children to engage with foundational technology and engineering concepts during their formative early childhood years. This study looks at a sample of preschool children (N = 98) from five early childhood centers in Singapore who completed a 7-week STEAM (Science, Technology, Engineering, Arts, and Mathematics) KIBO robotics curriculum in their classrooms called, “Dances from Around the World.” KIBO is a newly developed robotics kit that teaches both engineering and programming. KIBO’s actions are programmed using tangible programming blocks—no screen-time required. Children’s knowledge of programming concepts were assessed upon completion of the curriculum using the Solve-Its assessment. Results indicate that children were highly successful at mastering foundational programming concepts. Additionally, teachers were successful at promoting a collaborative and creative environment, but less successful at finding ways to engage with the greater school community through robotics. This research study was part of a large country-wide initiative to increase the use of developmentally appropriate engineering tools in early childhood settings. Implications for the design of technology, curriculum, and other resources are addressed.     

Moving from basic offerings to value-added solutions: Strategies, barriers and alignment

Commoditization erodes the competitive differentiation of companies and often leads to a profit squeeze. Existing literature recommends the transition from basic product offerings to service-based value concepts in order to regain competitiveness in such a context. This paper explores the concrete efforts of suppliers in the commoditized electro-technical industry to create new non-price-based customer value. In this paper, a taxonomy of efforts is developed which builds on the competitive strategy and strategic marketing literature. Our research identifies barriers to the market introduction of these new value concepts. Observations in this industry lead to a framework that (1) proposes alternative step-by-step strategies for making the transition from basic products to service-based solutions, and (2) offers alignment suggestions for overcoming identified barriers. Migration paths to introducing new service-based value concepts are incremental rather than radical, and managers should complement their market approach with (a) value chain actions to create multilevel industry support and (b) an organizational alignment approach.
