【摘要】：隨著社會分工的細(xì)化、服務(wù)業(yè)的飛速發(fā)展,企業(yè)服務(wù)采購的規(guī)模越來越大、涉及范圍越來越廣、重要程度越來越高,對所采購服務(wù)要求也越來越高,但服務(wù)質(zhì)量難于控制、服務(wù)評價主觀性強(qiáng),不同服務(wù)差異性較大,而目前對企業(yè)生產(chǎn)性服務(wù)的標(biāo)準(zhǔn)化程度不高、研究較少。服務(wù)采購決策過程中,需要適應(yīng)參數(shù)多變、不同信息融合的需求,這使得傳統(tǒng)的方法在解決此類問題時存在局限。軟集合理論是近幾年興起的一種新興的處理不確定性問題的建模工具,軟集合參數(shù)集易于拓展,軟集合決策映射函數(shù)較傳統(tǒng)方法更加靈活。目前,軟集合理論已經(jīng)被廣泛的應(yīng)用到管理、工程、生物等領(lǐng)域。本文在總結(jié)服務(wù)和服務(wù)采購特點的基礎(chǔ)上,構(gòu)建出基于模糊軟集合的企業(yè)服務(wù)采購決策模型。具體而言,將企業(yè)服務(wù)采購決策分解為采購方式的選擇決策和服務(wù)提供商選擇決策兩個緊密相關(guān)的過程,重點研究上述兩個關(guān)鍵問題,分別建模,不斷優(yōu)化,最終聯(lián)合作為企業(yè)服務(wù)采購決策模型的主體部分。通過將軟集合理論引入到上述問題的解決中,提出根據(jù)服務(wù)的價值和采購風(fēng)險決策服務(wù)采購方式,根據(jù)不同的采購方式和服務(wù)的特點建立相對應(yīng)的服務(wù)提供商選擇的選擇模型,并研究了模型的優(yōu)化問題。首先,建立基于模糊軟集合的服務(wù)采購方式?jīng)Q策模型。在對企業(yè)常用采購方式、服務(wù)和服務(wù)采購的特點歸納總結(jié)的基礎(chǔ)上,參考分類采購思想,分析影響服務(wù)采購方式選擇的因素,通過將這些因素分解為服務(wù)價值和服務(wù)采購風(fēng)險兩大類指標(biāo),通過對指標(biāo)的綜合、及與各種采購方式最適合價值和風(fēng)險值的比較,建立基于模糊軟集合的采購方式?jīng)Q策模型來進(jìn)行服務(wù)采購方式的選擇。然后,構(gòu)建了基于模糊軟集合的服務(wù)提供商選擇模型。以解決服務(wù)提供商選擇問題為目標(biāo)。首先,將軟集合理論引入到服務(wù)提供商的選擇模型中,提出了基于軟集合的服務(wù)提供商選擇模型。其次,針對高風(fēng)險低價值型服務(wù),結(jié)合區(qū)間直覺模糊集通過隸屬度、非隸屬度兩個標(biāo)度對服務(wù)提供商屬性進(jìn)行評估,構(gòu)建區(qū)間直覺模糊軟集合選擇模型,給出區(qū)間直覺模糊軟集合的加權(quán)平均算子、樂觀決策算子和悲觀決策算子,為中性、樂觀和悲觀條件下服務(wù)提供商選擇決策提供指導(dǎo),該方法以區(qū)間形式表示專家肯定、否定評價,能同時考慮服務(wù)提供商的確定性因素和風(fēng)險因素。最后,對高價值高風(fēng)險的服務(wù)提供商選擇問題,構(gòu)建基于模糊軟集合和TOPSIS方法的服務(wù)提供商選擇模型。通過模糊軟集合的映射函數(shù)將各種不同量綱、不同取值范圍、不同取值類型的定量、定性指標(biāo)進(jìn)行融合,并利用模糊軟集合的集合屬性和模糊軟集合的距離測度和貼近度等性質(zhì)來進(jìn)行服務(wù)提供商的選擇決策,在同時考慮采購成本和服務(wù)質(zhì)量兩方面因素的條件下,解決了高風(fēng)險高價值服務(wù)提供商的選擇問題。最后,考慮到企業(yè)服務(wù)采購研究的模型不成熟、需要持續(xù)優(yōu)化的特點,提出通過優(yōu)化和調(diào)整不同采購方式的最合適價值和風(fēng)險值優(yōu)化采購方式選擇模型,以進(jìn)行采購方式選擇的優(yōu)化;通過應(yīng)用基于模糊軟集合的參數(shù)約簡,進(jìn)行服務(wù)提供商選擇中參數(shù)指標(biāo)的優(yōu)化問題。同時討論和確定了企業(yè)實際應(yīng)用過程中,具體的優(yōu)化措施、優(yōu)化方法和步驟。
[Abstract]:With the refinement of social division of labor, the rapid development of the service industry, business services procurement increasingly large scale, involving increasingly wide range of increasingly high degree of procurement services are increasingly high requirements, but the service quality is difficult to control, service evaluation subjective, different service differences at present the production of services is not high degree of standardization, less research services procurement decision-making process, need to adapt to the changing parameters, different information fusion needs, which makes traditional methods have limitations in solving such problems. The soft set theory is a new modeling tool to deal with uncertain problems in recent years the soft set parameter set is easy to expand, soft set decision method is more flexible than the traditional mapping function. At present, soft set theory has been widely applied to management, engineering, biology and other fields. In this paper Based on the characteristics of service and service procurement, construction enterprise service procurement decision model based on fuzzy soft sets. Specifically, the enterprise service procurement decision into the choice of procurement decision-making and service provider selection decision two closely related process, focuses on the two key problems, model, continuous optimization finally as the main body of enterprise service purchase decision model. By solving the soft set theory is introduced to the above problems, according to the service value and purchase risk decision-making service procurement method, model selection based on different characteristics of procurement and service to establish corresponding service provider selection, and studies the optimization model at first, the establishment of decision fuzzy soft set based on service procurement model. In the way of enterprise procurement, procurement of services and service Based on the summary of the characteristics, classification of reference purchasing thoughts, analysis factors influencing the choice of service purchase mode, through these factors will be divided into purchase service value and service risk of two kinds of indicators, through comprehensive index, and purchase the most appropriate way of comparative value and risk value, establish the fuzzy soft set purchasing the way to service purchasing decision-making model based on selection. Then, build a choice model of fuzzy soft set based service providers. To select a service provider to solve problems as the goal. First, the soft set theory is introduced into the selection model of service providers, we choose the model of soft set based service providers. Secondly, aiming at the high risk of low value services, combined with interval valued intuitionistic fuzzy sets by degree of membership, non membership of two scales to evaluate the service provider attributes, construction area Intuitionistic fuzzy soft set selection model, weighted average operator interval intuitionistic fuzzy soft set, optimistic and pessimistic decision operator decision operator, is neutral, decision-making to provide guidance service providers optimistic and pessimistic conditions, the method in the form of interval expert affirmation, negative evaluation, considering uncertainty factors and risk factors. Service provider. Finally, the high value of high risk service provider selection problem, construct the selection model of fuzzy soft set and TOPSIS method. The number of service providers based on the mapping function fuzzy soft sets of different dimensions, different range, different types of quantitative values, fusion of qualitative indexes, and close to the decision the degree of nature to the service provider using a collection of attribute fuzzy soft set and fuzzy soft set distance measure, taking into account the purchase cost The two factors and the quality of service conditions, solve the problem of selecting the high risk and high value service providers. Finally, considering the research enterprise service procurement model is not mature, characteristics of continuous optimization, put forward through the optimization and adjustment of different procurement methods most suitable value and risk value to optimize purchasing mode choice model, for optimize purchasing mode choice; through the application of parameter reduction based on fuzzy soft sets, optimization parameters of service provider selection. At the same time to discuss and determine the actual application process, specific measures, methods and steps of the optimization.
