Textile yarn inventory management enterprise content management to only very few types of materials - that is just managing the inventory of each yarn types (such as to provide information "Cotton 40 single-ply yarn inventory 30 tons"), but at least need to manage the yarn batches and technical personnel believe that the same batch of yarn can be common. Although the same types of yarn (such as cotton 40 single-ply), different batches may be the quality, technical indicators vary widely (eg, strength, evenness, the actual thickness, etc.), information management system, if not separate, such inventory data for production, project management is extremely limited role.
Component-level refers to a certain category of materials, inventory, information management needs in the products to each one usually can not be accurately sub-units, such as a cheese, a shaft, a cloth roll and so on, the management of every one that such materials individuals are special, have different properties. Different textile enterprises, depending on the degree of their information on the components of different levels of information management degree vary widely. Some of the higher degree of information technology companies can manage each of the root axis, each roll of cloth of information, and some of the cheese due to the use of a higher unit value, and even follow-up management to each tube.
3. Textile production and processing of information characteristics.
Referred to the textile industry, information technology, a lot of people think of first is a headache to the textile industry of information uncertainty. This uncertainty is the textile industry in the production process refers to the many uncontrollable factors have contributed to some of the same "cause" may lead to different "fruit" (Of course, the "cause" must be different, but this "for" general information system is difficult to capture).
Air humidity, atmospheric pressure, and water changes, may seriously affect the production of results. For example, the same yarn, same weight of the cheese, due to the impact of moisture regain, or because the actual yarn count and standard deviation of yarn count, they are most likely different in length, while the textile yarn length is a very important process considerations . Another example is the same length of the cheese, after warping into a beam after (film yarn), since the whole process if the tension is different from the length of yarn, may lead to films are also different. In addition, the same length of the beam, to weave cloth may have different lengths, different finishing environment, can lead to different levels of fabric shrinkage or stretching. A number of factors before deciding on a textile production process the information in the uncertainty.
No matter the kind of industry, information technology will inevitably face massive issues of information, but in the textile industry, such features seem more prominent. Textile enterprises in the production process, from raw material input to the output of finished products are usually a result of these intermediate states (in weaving, for example): cheese, thin shaft, pulp shaft, beam, gray cloth roll, finished fabric rolls. In general have these basic processing steps: winding, warping, sizing, weaving, finishing, dyeing, printing and so on. Around these materials, and these processing steps, also sent birth to a large number of "batches", such as batches of raw materials storage, sorting batches, batch dyeing, packaging batches, batch, etc. out of libraries. In the production process around the state, steps, batch will have a huge amount of information.
4. Textile enterprise quality information characteristics.
The textile production process quality control of many uncertain factors have led to a textile enterprises in the production process difficult, and many people, the natural environment will affect the textile industry of the product quality. The quality of information on textile enterprises There are two major characteristics, namely, massive nature of the difficulty of first retrospective.
As the textile production process, quality control difficulties, the textile companies usually set up in all processes of quality control points, these quality control points in the testing process will generate a lot of information, such as each of the original yarn storage testing, each volume gray test, each finished roll of cloth detection. To fabric inspection, for example, information systems need to record the volume of each fabric defects, defects of the starting location, type, length, etc., a medium-sized enterprises, need to be inspected every day thousands of rolls, will produce a lot of quality information .
The textile production process, sometimes the process of integrating material (such as warping, sizing, sewing, etc.), sometimes the process of splitting materials (such as drop-cloth, open cut, the distribution of co-dyed yarn, etc.), in which merger and sub - the process of demolition often lead to the interruption of quality information in order to trace the quality of the information difficult.
Second, the textile enterprise information management system requirements
From the above characteristics of the textile business information analysis can be seen that a good textile enterprise information management system should have the following characteristics:
1. Flexible encoding method and materials BOM expression.
A good textile enterprise information management system, there should be a flexible material encoding, so that the file materials with the succession, both to meet the material file management requirements, but also does not produce unnecessary redundant data.
The expression of the BOM should not be limited to a pro rata basis sub-material consumption, while the need to be considered under certain circumstances, the absolute consumption, as well as under different processing processes may have different consumption ratio.
2. To support different levels of inventory information management.
A good textile industry information management system that can support different levels of inventory information management, to manage storage areas, batch, containers, packaging, components, and so on, through these management configuration, can support yarn, axes, cloth and other inventory information management.
3. Scientific information collection methods.
Textile companies have a mass of information, uncertainty, in order to reduce uncertainty we need to gather more information in order to analyze these uncertainties lead to a causal relationship, which in turn increased the mass of information. Thus, a good information management system for the textile industry, it should be flexibility to use a variety of methods for data collection, according to the user's actual needs, manual entry, bar code, scan guns, PDA, RFID, through the machine to read data such as network interface combination of collection methods used to improve the timeliness of production data collection, accuracy, economy.
4. Machine Interface support.
The use of a large number of textile enterprises from Japan, Europe, the world's most advanced textile machinery. These machines are generally with a network interface, and even some in the textile machinery with its own control system, through these interfaces and central control systems, management software can exchange data directly with the machine. No doubt, these interfaces, the control system for textile machines have great impact on purchasing decisions, business leaders eager to improve enterprise through their control of the level of automation can be scientifically productive capacity of enterprises to control, integration, improve enterprise machine efficiency, reduce idle time. Thus, a good information management system for the textile industry, we should have an open data interface, with built-in interface program or can be easily customized interface program development in order to read data directly from the machine or even direct control of the machine.
In short, the textile industry in various sub-sectors has its own different production, technological characteristics, but their message is there are many commonalities, and this paper attempts to analyze the process of the textile enterprises in the operating characteristics of the information generated by the hope and engaged textile enterprise information construction in the textile industry colleagues to explore a common way of information technology, although the walk up this road may be very difficult.
