Restaurants operate in a dynamic highly competitive business environment with slim profit margin, changing customers, and costs incurring from materials and labour. Despite a solid demand for restaurant meals, the restaurant industry has a high failure rate, especially within the first three years of commencement. As the most important marketing, sales, and operational tool, a menu list must be well designed and well planned for profitability and competitive advantage. Menu Analysis (MA) or Menu Engineering (ME) refer to the broad range of techniques and procedures applied for effective marketing and operational decisions on menus. Choice of dishes is the food and beverage manager or the decision maker’s (DM) challenge which is a critical strategy decision. Quantitative or precise measures required for accurate evaluation of the effectiveness of a menu item is difficult to obtain. This pioneer study presents a Menu Management Decision Support Model (MMDSM) that applies Fuzzy Multicriteria Decision Making (FMCDM) approach to deal with the inherent imprecision in input using qualitative linguistic input values and obtain reliable outputs with increased decision options. Improving the widely used ME model with two inputs, the MMDSM includes four input parameters of Profit Factor, Popularity, Contribution Margin, and Sales Price related to each Menu Item. The MMDSM is successfully tested with a case study having one hundred and sixty-one Menu Item details from a U.S. restaurant. The results are verified by conducting a sensitivity analysis and the model can be developed into a commercial application.

Introduction. An overview of research in the field of classification as a method of machine learning is given. Articles containing mathematical models and algorithms for classification were selected. The use of classification in intelligent management decision support systems in various subject areas is also relevant. Goal and objectives. The purpose of the study is to analyze papers on the classification as a machine learning method. To achieve the objective, it is necessary to solve the following tasks: 1) to identify the most used classification methods in machine learning; 2) to highlight the advantages and disadvantages of each of the selected methods; 3) to analyze the possibility of using classification methods in intelligent systems to support management decisions to solve issues of forecasting, prevention and elimination of emergencies. Methods. To obtain the results, general scientific and special methods of scientific knowledge were used - analysis, synthesis, generalization, as well as the classification method. Results and discussion thereof. According to the results of the analysis, studies with a mathematical formulation and the availability of software developments were identified. The issues of classification in the implementation of machine learning in the development of intelligent decision support systems are considered. Conclusion. The analysis revealed that enough algorithms were used to perform the classification while sorting the acquired knowledge within the subject area. The implementation of an accurate classification is one of the fundamental problems in the development of management decision support systems, including for fire and emergency prevention and response. Timely and effective decision by officials of operational shifts for the disaster management is also relevant. Key words: decision support, analysis, classification, machine learning, algorithm, mathematical models.
