The dissertation analytically and practically substantiates the feasibility of ice cream recipe calculation by creating expert modeling system (EMS).
The ice cream recipe modeling process was studied using the CASE tool Erwin Process Modeler and the main business processes as well as the information flows that provided them were identified.
The structural and functional model of EMS and its components are designed to effectively support the process of modeling ice cream calculations as well as to provide flexible further upgrading and integration of the system with the industrial and information complex of any enterprise in this sector. A mathematical and algorithmic apparatus to obtain optimal ice cream recipes for a given quality as a component of the expert system is developed. It is based on the developed method of modeling ice cream recipes, which, unlike traditional ones, uses the expert data processing technology and optimization methods.
The EMS architecture consists of four separate blocks: a database, a knowledge base, software modules to implement the mathematical apparatus and quality control functions of the recipe composition and its technological applicability, user interface.
The database provides the primary information on recipe ingredients and their physical, chemical, functional and technological properties, auxiliary materials as well as quality indicators. It stores user-targeted data on recipe composition, physical and chemical characteristics of ingredients, recipe status.
The knowledge base covers product rules regarding technological characteristics of ice cream manufacture. The knowledge base is designed to store the long-term facts that describe the technology and ice cream production, the rules that define the relationship between these facts, and other types of declarative knowledge.
Mathematical apparatus modules are used to implement ice cream recipe modeling algorithms as well as to provide some recipe versatility due to the possible interchangeability of individual technologically active components. They have great practical importance in the process of product production.
Expert modeling system provides recipe correction that takes into account all technological properties of multicomponent food systems by using the knowledge base. If you simulate the optimal recipe only with the help of mathematical apparatus without the expert system usage, the obtained recipe is unlikely to be suitable to use, because the numerous technological properties are not taken into account.
The designed system allows purposefully manage the quality of the finished product during the technological process of its production. The greatest importance of the research lies in the automated selection of traditional recipe component replacement for fundamentally new ones based on natural raw materials.
Developed allows purposefully manage the quality of the finished product during the technological process of its production. The greatest importance of the development lies in the automated selection for the replacement of traditional prescription components fundamentally new based on natural raw materials.
The economic impact of the expert system implementation, derived from the research results and embedded in the EMS knowledge base, will improve the commercial component of the enterprise's activities by saving working time as well as costs of raw and auxiliary materials. The designed EMS will provide prompt, well-ground information to make the right technological decisions. The use of EMS will integrate the knowledge of scientists of different specialties as well as reduce the cost of complex laboratory studies while selecting ingredients in modeling new ice cream recipes.
