Decision Making Method Based On Different Preference Information And Its Application Research

Decision making is designed in view of the need to solve specific problems,using scientific theory and method of systematic analysis of subjective and objective conditions,all kinds of feasible solution is put forward,and choose the best scheme of a set of activities.Decision is in human social activities,the products of itself has its own long history,in this day and age,along with the progress of the society,along with the development of modern computer technology,along with science and technology rapid development,people to acquire knowledge and get forward sharp explosive increase in the amount of information,decision-making problem gradually develop from simple to more and more complex,decision-making environment has become more and more tend to be complex,decision analysis as a comprehensive subject of science,in the economic,management,and other fields of social life are everywhere.The decision making process is in all kinds of feasible scheme selection,as far as possible to meet the desire of the decision-maker and requirements.In the country,the government,enterprises and institutions,individual cannot leave the decision,the decision as a basic human activity,is a kind of guiding people to action,is people to achieve a certain purpose or goals in many feasible scheme selection process.Along with society's progress and the development of management science,today,no longer Making a Decision is based on a single attribute,but become more complex,have to consider a variety of factors mutual restriction and mutual contact(guidelines),this kind of Decision problem is called multiple attribute Decision Making(MCDM,Multi-Crieria Decision Making).MCDM is a important branch in the field of decision analysis,dealing with a finite number of solutions in multiple attribute decision-making problem,under it is obvious that such decisions exists in the social economic field,in the field of practical production,engineering and field,and every aspect of our lives.Such problems tend to be two prominent features,it is not the commensurability of each attribute and the contradiction between each other,that is no unified dimension between attribute,a property value changes tend to cause the loss of another attribute value;2 it is the decision itself is geared to the needs of future events,complex and changeful environment,the information is not entirely sure,especially the decision-makers subjective attitude,pressed for time and other factors will affect the decision accuracy and scientific.Therefore,in this paper,according to different category preferences situation decision problem,research on multiple attribute decision making problems,the processing method for the classification of decision and multiple attribute decision making research work provides theoretical basis and technical support.In this paper according to the train of thought for studying the distinguished,from easy to difficult,according to different category preferences of multiple attribute decision making problems to carry out the related research,the main work is in the following six aspects.(1)With multi-granularity linguistic environment schemes can be preferred case study decision-making method.In practical problems,especially by evaluation scheme more cases,experts often for sensitive part of the plan,so as to give the following information: think some solutions should be the top,a few obviously should be obvious row in the column,from a few schemes can extent should belong to the same category,essentially belongs to the case study and analyses of the under special preferences.So,this kind of new decision making problems,policymakers to the category of the part of the plan have not completely belongs to preferences,at the same time scheme of information such as attribute is given in multi-granularity linguistic form.Study according to the grey target decision framework,determine the plus or minus the bull's-eye of different granularity of language,different granularity language distance granularity unified into standard language,on the plus or minus the bull 's-eye connections in a solution of the projection,for integrated distance to target for all solutions of comprehensive and minimizing the sum of the bull's-eye distance category preference structure model,to solve the model of attribute weights,thus the order relation of solution is obtained.(2)Incomplete information environment based on typical sample classification method of case study research.In the case of urgent time limit,the decision situation,experts tend to form the parts schemes have relatively clear category belongs,decision making judgement conclusion unclear situation,can also be called expert is the category of incomplete judgment information for solution.Investigate its reason is various: due to the limitations of experts in the aspect of professional knowledge and attention to unrael,category of some of the decision scheme is given preference information is difficult to accurately;in case of an emergency,experts in a given period of time,special hard environment for some decision clear evaluation;within the time limit,cannot complete decision category of sorting and summary and so on.For this kind of problem,essentially belongs to the incomplete case study and analyses of the categories under preferences.How to make good use of experts have given scheme category preference information,sorting and scheme of all categories of judgment is very worth studying.Given the simplicity of the application of TOPSIS method and the practical value of case study method in the study to the category of all schemes are relatively close to the minimum and different category scheme between the average degree of maximum category preference structure model,to solve the model of attribute weights,thus the order relation of solution is obtained,and the category of belonging judgement for unknown category scheme.(3)Dual category preference information environment research case study of the classification method.In multiple attribute decision making process,often there are dual classification information,namely overall category preferences at the same time,experts give scheme and category under partial attributes is given preference,signal under certain properties or characteristics of a part of the solution is similar.With the complexity of the decision environment,experts in multiple attribute decision making process and provide the corresponding preference information is very common situation,all kinds of information in source,content,characteristics,etc.There are many different,but in summary can be summed up in two categories: the experts on the basis of professional knowledge,their own experience,identity under the background of solutions in some indexes such as the category of the preference information are given,is part of the multidimensional index to measure performance,can be called attribute category preferences;experts from the overall grasping of the features of the performance of all indicators to measure performance,can call plan category preferences.To solve these problems,study presents an account of the differences of indicators "dominant" and "hidden" of the multiple attribute decision making model.The method based on expert scheme category information is given in advance through the assessment of indicators in the category of dominant degree are identified,using the attribute value under different degree of dominance relatively ideal point distance relationship model,thus optimizing the index weight,determine experts have dual classification preference scheme decision-making environment.(4)The decision makers to attribute has more incomplete judgment information method of case study research.Policymakers in multi-index linguistic decision matrix is given,in his familiar fields or properties for some solution is given under the specific category of belonging,the author will this kind of problem is called a group of people is to attribute decision making problems with incomplete judgment.Typical of this kind of problem exists in many interest subjects of group decision-making environment,because of the subject field,the knowledge structure,decision-making experience,expression ability,can have different personality traits,in their respective horizon,cannot simultaneously for all solution to be able to give a direct and complete the category of the judgment information,they are likely to have the incomplete solution is given according to the category preferences.With the given category preference information is often out of different motives,and have different sight Angle,attributes in multiple decision makers are not completely determine how to make full use of different information conditions given the category of the preference,and then prioritize very worth studying all solutions.The authors studied some key problem in the process of analysis,including how to deal with the conflict of different decision makers give category information,how to identify recurring attribute value and use information so as to optimize the attribute weights,the purpose is to do some exploration for the group decision-making of incomplete preferences.(5)Multiple stakeholders the preference information on alternatives have category method of case study research.Multiple main body has preference category belongs to the part of the plan,and multiple subject interest relations,the weights of the unknown,reduced the preference information on alternatives have a category for stakeholders decision problem.Respectively by using the case study method and category preference information related to the principle of fuzzy sets,respectively,to optimize the attribute weights and the weights of various decision-making body,before and after by satisfying the subjective preference information categories of different decision-making and group decision-making of objective facts,in originally under the environment of interest relations group decision-making problems find the master-slave relationship,plural and obtain satisfaction method can compromise between multiple subject,environment so as to objectively reflect the subject of the relative importance of each attribute and the decision-making level of each subject.(6)Applied undergraduate engineering class to cultivate students' ability of performance evaluation research.College students' quality structure and students' quality education content is complementary to each other,how to define the structure also determines the students' quality in how to define the level of college students' quality education.College students' quality structure has both the universality of the quality of the structure,but also has its own particularity.In case study stage for domestic and foreign well-known colleges and universities of engineering students quality training research analysis,from the Chinese engineering education accreditation,the general standard of 10 graduation requirements of the present stage engineering students to cultivate multi-field and multi-level investigation statistics,after a thorough investigation,sampling surveys,major surveys and other research method combining the data of investigation system,how to cultivate students present situation of the quantitative data information collection;Comprehensive comparing domestic and foreign university related to cultivate students' ability,the quality training to conduct a comprehensive,integrated,objective comments.The influence factors of students' quality for engineering specialty were analyzed,and specific analysis of the influence factors of the student ability quality,influence the influence extent of source and analyze the key influencing factors and function of the way;Combined with the influence factors of students' quality evaluation,building maturity assessment model of students' quality;Needed according to the requirements of standard degree,the cultivation of the current situation of "requirements" qualitative description and quantitative estimates,for some typical case situation of students' quality training to calculate and compare.Research on the students' quality education in colleges and universities teaching the subject business training in the linkage effect,put forward the applied undergraduate engineering students to cultivate the practice path.
