Application Of Computer In Filature——cocoon Cooking Technical Designing Expert System

This thesis adopts VFP database manage system (DBMS), OO(Object Oriented) programming and SAS statistic analysis software. Starting with the impacting factors on cocoon-cooking technique of filature production, the system analyzes diversified data information, along with the relativity of various parameters used in technical designing. Based on those, we scheme out the structure composing and system flow chart of cocoon-cooking problem-consulting , also develop maintainable and practical technological designing subsystem with friendly interface, simple operation and fine security. Thus a perfect Cocoon-Cooking Technological Designing Expert System (CCTDES) comes into being.The paper analyzes collectivity structure of CCTDES, plots out each function module of this system in reason by means of VFP DBMS after mastering correlated parameters of cocoon cooking. The system achieves the acquisition, query, modification and the edit of data or knowledge. The knowledge of CCTDES is expressed with VFP6.0 database. Such database subsystems are developed as cocoon material, water quality condition, disadvantages of cocoon cooking, and facility of factory, raw silk classification standard, as well as technological designing subsystem. Moreover technical designing module, expert auditing module and system assistant module are discussed in the system. The collectivity structure and flow chart of the system are designed. Adopting OO(Object Oriented) visual programming in application, then the system implements such function: data inputting,querying and browsing, modifying and editing, report form printing, data collecting and calculating, problem consulting of cocoon-cooking as well as system maintaining..During the modeling of technological designing, SAS release6.12 statistic analysis software are applied on correlation and stepwise regression for cocoon-cooking parameters and material data of past years. The significance test and F test are used to analyze the result. We constituted the primary model of cocoon-cooking technique. Considering some restricting factors, the model can be improved to utilize the material, facility and manpower reasonably. After being optimized, we can get the best parameter combination and technical model.After being tested, the system achieved our designing aim; it can run exactly and unfailingly. It has evident superiority, contrasted with handwork. This system is driven with multilevel menu to select and visit the databases. The users can adjust some parameters according to their native information, to form a coincident expert system for their circumstances. Assistant function module includes calendar, calculator and password rejiggering. Innovation was used on setting function key, shortcut key, combination key, shortcut menu and hint message. On designing form, the system uses multi-media technology and runs under the platform of WINDOWS platform. It has favorable operation capability, person-computer alternation interface (vocal, vision, text), convenient and secure operation, and suit to common designers.
