II. Problems before the implementation of pdm/plm

2.1 rapid changes in customer demand, tight R & D tasks, affecting the number of orders, and strong demand for shortening the R & D cycle

Nanjing Weifu Jinning Co., Ltd. is in the automobile industry with relatively rapid development and increasingly fierce competition, especially in the automobile parts manufacturing industry. The market competition is becoming increasingly fierce. Enterprises not only have to face the competition of domestic peers, but also foreign automobile parts manufacturers with relatively strong strength, such as Delphi, Bosch and other foreign excellent manufacturing enterprises have set their manufacturing plants in China. Foreign companies have rich enterprise management experience, Innovative product design, short R & D cycle of new products and high standard product quality have caused great competitive pressure in China

on the other hand, in order to meet the requirements of the WTO, China's automotive industry has gradually become in line with international standards in recent years, and has continuously relaxed the administrative restrictions on foreign enterprises entering China. At the same time, both the state and industry management departments have also raised the entry threshold of the automotive industry of domestic enterprises. Market competition also requires enterprises to constantly adapt to new industry management standards or new national laws and regulations, such as QS9000 in the automotive industry, TS1694 China is a large country of chitin resources. 9 it has become a recognized quality management standard. Customer manufacturers have higher and higher requirements for various production part approval procedures (PPAP) documents provided by enterprises, and various environmental protection indicators and regulations constantly require enterprises to launch new products

the product formation and development process of the auto parts industry must go through several stages: sample design and manufacturing, small batch production, and mass production. QS9000 and TS16949 also stipulate that the product development process must comply with APQP advanced prduct quality planning

the development process of new products in enterprises is relatively long. An important reason is that the whole process from market to product design and development, from product design and development to manufacturing process design and development, and then to batch manufacturing is not strictly regulated. The information transmission of the process is not timely and accurate enough. There are also inconsistent information. The efficiency of business communication is still relatively low, More importantly, there are many changes in the process of product design and development. One of the most important aspects of accelerating the R & D cycle of new products is to minimize mistakes in the early stage of design and development, and try to correctly and quickly convey the customer's information and product characteristics to the product design, process design, manufacturing department, and sales service department in the product design and development stage, and collect and summarize all aspects of experience and opinions to the product designer; The designers of products and processes also need to convey the design characteristics and manufacturing requirements of products to the manufacturing units in a timely and accurate manner in the process of development and design. In short, the new product development process of enterprises needs to be controlled by a standardized project management process, and all participants work on the same information sharing platform, so as to achieve the purpose of shortening the development cycle of new products

2.2 the R & D process is difficult to meet the requirements of APQP, and the PPAP documents of supporting manufacturers are strict, resulting in a huge workload

due to the industrial characteristics of the automobile manufacturing industry, the batch manufacturing of products and the quality requirements of batch products are very high. In order to meet such requirements, enterprises must carry out detailed product formation process management. The content of the management process is reflected through a large number of documents. At the same time, when supporting manufacturers to provide samples to enterprises, It is required to provide very complete PPAP (production part approval process) documents, that is, the parts manufacturers are required to provide quality control process documents

on the one hand, enterprises urgently need a software tool to quickly form and reasonably classify and manage these documents, especially the standard template of these documents in a unified enterprise. On the other hand, it is to provide a fast tool for centralized document management and retrieval, which can quickly use the contents of various documents that have been formed

of course, these documents should be generated in which step of the product design and development process, by whom, how to generate, how to associate information, how to share information, and how to archive and formalize in batches, which are also important issues faced by enterprises

2.3 information island of product data

after years of information construction, enterprises have used various computer software tools in the design department for a long time. These tools have played a good role in improving daily work at different stages

but it also brings some obvious problems. The electronic documents generated by these different applications and different versions of applications are usually incompatible with each other, such as the version of CAD tools, resulting in the problem of information sharing, and CAPP process files can not be well shared. If the enterprise needs to share these data, it must install various computer software tools on the relevant computers. These seemingly centrally managed files form an information island scattered in different computer systems. Information cannot be browsed by most systems, data cannot be extracted, and it is difficult to reuse. In order to solve the problem of browsing some data, enterprises may invest more money to buy professional software to install it into the computers of relevant personnel, which is also a waste of investment

2.4 security sharing of product data

the sharing of product data is, on the one hand, the sharing of product data between departments, on the other hand, a reference of historical product design data to existing product design. In fact, due to the lack of product data at present, it will bring more value to the relevant market segments. There is no sharing mechanism. It does not take products and parts as the organizational form, and does not take part feature parameters as the retrieval conditions. There is a lack of connection between various product data, and product related data cannot be obtained by following the passage. This situation greatly affects the development progress of products

designers often pay more attention to the improvement of design efficiency brought by a certain design software, but in many cases, they ignore the fact that there is not much time really used for design and drawing, and determining the design scheme is the most important thing, but retrieving the previous design scheme and finding relevant technical documents, the time of technical standards takes about 40% of the design time. Not to mention the time and effort spent on data sharing between departments after design submission, especially the latest data sharing after data changes

in terms of technology accumulation and technology sharing, an information platform has not been formed, an operating mechanism has not been provided, and intangible assets have not been fully utilized

with the increasingly fierce market competition and the frequent flow of talents, informatization also brings difficulties to the management of intangible assets and knowledge wealth of enterprises. How to safely manage the intangible asset resources of enterprises is also a practical problem that enterprises have to face. In the current situation, security and sharing are an irreconcilable contradiction

2.5 design standardization and generalization

in Nanjing Weifu, a large number of product research and development is the research and development of variant products, but the actual situation of the enterprise is that various parts and components are not reasonably classified and managed according to structural features, physical features, or manufacturing features. In the process of product research and development, it is impossible to retrieve the information of various parts and components resources existing in the enterprise, and there is no timely statistics of parts and components that have been used repeatedly, It has become a common part of enterprises. There are still many repeated designs within the enterprise, resulting in the formation of a relatively large number of components with similar functional structures and slightly different designs, which also causes difficulties in production, management, outsourcing and outsourcing, and also makes it difficult for the enterprise to solve the problem of inventory backlog

2.6 change of product data

from the product formation process of Nanjing Weifu, it has gone through different production and manufacturing stages, such as sample, batch test and large quantities. Some parts will also be changed in the later stage of prevention and correction. At these different stages, different versions of drawings are scattered in the computers of different personnel in various departments of the enterprise, which brings relatively large management problems to the technology and production departments of the enterprise. Enterprises urgently need to centralize the management of all versions of product parts according to the production stage and the life cycle status of parts, strictly control the changes of parts, and keep the change request and reason of historical versions, and trace the contents of changes

2.7 information system integration

the enterprise has implemented Kingdee's k3/erp system, but because the design data is mainly stored in the design drawings, the product BOM data in the K3 system still depends on manual maintenance, with heavy workload and low efficiency. The design list cannot reach 1833 units in a single month in December, which can be quickly and accurately transferred to the K3 system; What is more serious is that once the design is changed, the data in K3 system must be changed at the same time, so it is difficult to ensure the consistency of data

another problem is that the manufacturing BOM should consider the needs of outsourcing and manufacturing process. There is a big difference in structure from the design BOM, so the maintenance of BOM data is more difficult, which also causes the production management system in the ERP system with large enterprise investment not to be fully implemented
