【摘要】：上個世紀九十年代對易逝品的研究使得易逝品有關的研究積累了一系列的成果,隨著科技的發(fā)展和經濟環(huán)境的更新,原有的研究問題在新時期具有新的研究意義和研究必要性。易逝品作為零售行業(yè)中利潤率較高的銷售產品促進了零售業(yè)的發(fā)展,不同的研究出發(fā)點結合不同的現實背景得到了不同的管理結論。鑒于理論與實踐存在的差異,原有的有關易逝品的研究結論在新的商業(yè)模式下或許變得不再適用,因此結合新的理論和現實問題發(fā)展新的理論模型十分必要,并且有利于豐富和發(fā)展易逝品自身的研究內容和范疇。本文從易逝品的固有屬性出發(fā),結合運營管理和市場營銷以及生物學科領域的知識,創(chuàng)造性地將易逝品的傳統(tǒng)模型進行了改造,并借助新的研究方法和視角對易逝品的庫存管理問題進行了探討。研究重點對易逝品的廣告努力和利潤最大化問題進行了分析,論文的主要研究內容、研究方法和研究創(chuàng)新主要如下:(1)研究了乙烯效應和廣告努力情境下的易逝品庫存管理模型。假設易逝品的數量會影響產品的變質程度,并構建了逆向庫存影響需求的模型。基于控制理論方法,研究了二維微分方程,對易逝品的庫存管理模型進行了理論研究和分析。研究給出了模型最優(yōu)解存在的必要條件,模型部分重點分析了給定計劃周期情境下的庫存模型。研究假設需求受價格、商譽、庫存影響,并對最后產品的情況也進行了補充說明。理論部分重點對最優(yōu)廣告存在的必要條件以及凹凸性問題進行了分析,同時給出了最優(yōu)商譽和庫存變化的表達式。由于模型結論的復雜性,分析部分采用矩陣的表達方式給出了最大利潤的表達形式。(2)由于只研究一個零售商的廣告努力使得模型的結論比較單一,缺少從系統(tǒng)的角度進行分析,而定價問題一直是庫存管理理論研究的重點,因此分析動態(tài)定價成為進一步探討的方向。本文對零售商實體店面客流量作用的闡述,給出了網絡渠道是一種固有的現實競爭因素的理論假設,因此在模型的需求模型部分引入了產品渠道兼容度的概念來描述這種現象,同時假設商譽和價格共同影響市場需求。模型部分不考慮訂貨或缺貨問題,僅對現有的庫存進行廣告努力分析。研究首先是假設零售價格固定,給出了廣告努力的最優(yōu)表達結果,同時借助控制理論對理論結果進行了說明。此外,假設零售價格動態(tài)變化,采用同樣的理論分析求解得到最優(yōu)廣告努力和商譽的表達結果,對復雜結果進行算例分析給出直觀表達圖表。研究分析部分對動態(tài)策略和靜態(tài)策略進行了橫向和縱向對比,結合重要的參數對模型進行了敏感分析,結果總體認為靜態(tài)定價的實施效果比動態(tài)定價好,但需要結合實際經營環(huán)境進行策略的靈活調整。研究還分析了資金周轉率,對不同復雜的市場模擬環(huán)境進行了分析,分別給出了研究對策和建議。論文構建的易逝品模型更加貼近現實意義,且豐富和完善了以往的研究問題,在新的理論方法視角下,得到了一些具有創(chuàng)新性的研究結論。(3)討論了二級供應鏈下的易逝品庫存管理模型,并假設存在多個訂貨周期,供應商給予零售商按時補貨,考慮了在學習效應影響下的庫存管理模型。研究仍然集中在乙烯效應下的模型分析,研究重點在理論的推導和分析上。在給定的研究背景下,學習效應和乙烯效應的雙重影響對供應鏈的整體利潤會產生影響,因此從總體利潤最大化的角度對模型進行了算例分析和探討。研究對訂貨數量和乙烯強度的分析具有創(chuàng)新性,得到了一些新的結論和管理建議。對模型的求解部分,給出了利潤最大化存在的必要條件以及優(yōu)化分析結論。(4)借助控制理論方法來分析易逝品庫存管理具有創(chuàng)新性,整合了運營管理和工程學科兩方面因素。同時研究首次對易逝品的數量問題進行更加微觀的分析,以更加貼近現實問題。此外,動態(tài)廣告在易逝品的研究領域尚缺乏,采用多維微分方程來分析易逝品庫存管理使得研究視角具有創(chuàng)新性。研究對單一零售商和二級供應鏈分別進行了分析,重點圍繞易逝品的動態(tài)變質概念展開研究,并基于微分模型和控制理論來構建模型的分析部分。總體而言,基于動態(tài)變質的概念,發(fā)展和擴展了現有的易逝品研究范疇,完善了現有理論以及豐富了庫存管理的研究內容。以上研究成果豐富和發(fā)展了傳統(tǒng)易逝品庫存管理理論的研究內容,并促進了學科交叉研究,能夠為管理者提供更加具有現實意義的決策分析依據。
[Abstract]:Study on perishable goods in 90s of last century the perishable product related research has accumulated a series of achievements, with the development of science and technology and economic environment to update the original research questions, significance and necessity of research in the new period. The new perishable goods as a higher margin retail industry sales promotion products the development of the retail industry, different research starting point with different background are different. Conclusion as the differences between theory and practice, the conclusion about the research of the original Xu perishable goods are no longer applicable in the new business mode or so, combined with the new theoretical and practical problems of the development of the new model is necessary, and to enrich and develop their own research content and category of perishable goods. This paper from the inherent property of perishable goods, combined with operational management and marketing and Physical discipline knowledge, creatively the traditional model of perishable goods was improved, and with the help of research methods and new perspective inventory management for perishable commodities is discussed. The research focuses on perishable product advertising efforts and the profit maximization problem is analyzed, the main research contents of this paper, research methods and the main innovation is as follows: (1) study the perishable product inventory management model of ethylene effect and advertising efforts under the situation. Assuming that the number of perishable goods will affect the degree of metamorphism of products, and the construction of the model of the demand impact of reverse inventory. Control theory based on the method of differential equation of two-dimensional model of inventory management for perishable commodities the theoretical research and analysis. The research gives the necessary conditions for the existence of solutions of the optimal model, the model part focuses on the analysis of the inventory model for a given program cycle context. The hypothesis of demand By the price, goodwill, and the effect of inventory, the final product was also added. The theory part focuses on the necessary conditions of optimal advertising and convexity problems were analyzed and the expression of the optimal goodwill and stock change are given at the same time. Because of the complexity of the conclusion of the model, analysis using expression matrix is given the expression form of the largest profit. (2) because of only one retailer advertising to make the conclusion of the model is relatively simple, the lack of analysis from the perspective of system, and the pricing issue has been the focus of theoretical research on inventory management, so the analysis of dynamic pricing has become the further research direction. In this paper, the retailer store traffic. The proposed network channel is a realistic assumption inherent competitive factors, so in the demand model introduced drainage products Said the concept of compatibility degree to describe this phenomenon, at the same time that common goodwill and the price impact of the market demand. The model does not consider the part of order or out of stock, only the existing inventory to analyze advertising. First is the assumption that the retail price is fixed, gives the optimal advertising to expression results, at the same time with the control theory to illustrate the the theoretical results. In addition, the retail price changes the dynamic hypothesis expression results using the same theoretical analysis to solve the optimal advertising efforts and goodwill, to complex results for example analysis give visual expression chart. Analyses the horizontal and vertical contrast of dynamic and static strategy strategy, combined with the important parameters for the sensitivity analysis of the overall model, that the implementation effect of static pricing than dynamic pricing, but need the actual operating environment of flexible strategy The adjustment. The study also analyzed the capital turnover rate, to various market simulation environment is analyzed, the study of countermeasures and suggestions are given. This paper constructs the model of perishable goods is more close to the practical significance, and enrich and improve the research in the past, in the perspective of theory of new method, obtained the conclusion has some innovative research. (3) discussed the perishable product inventory management model of two level supply chain, and assume the existence of multiple order cycle, the supplier give retailers on time replenishment, considering the inventory management model in the learning effects. Research is still concentrated in ethylene under the effect of model, focus on derivation analysis on the theory and research background. In the case of the double impact of learning effect and the effect of ethylene on the supply chain's overall profit impact, so the overall profit maximization model of angle An example is studied and discussed. The innovative analysis of the quantity and intensity of ethylene, obtained some new conclusions and suggestions of management. To solve the model, the necessary condition is given for the profit maximization and optimization analysis conclusion. (4) with the analysis of innovative inventory management of perishable goods control theory method, the integration of the two aspects of operation management and engineering disciplines. At the same time, research on the quantity of perishable goods for the first time to analyze more micro, with more realistic problems. In addition, dynamic advertising in perishable products research field is still lacking, the multidimensional differential equation to analyze the perishable product inventory management makes the research angle of view is innovation. Research on single retailer and two echelon supply chain were analyzed, studied the dynamic metamorphism around the concept of perishable goods, and based on the differential model and control Analysis of the theory to construct the model. Overall, the concept of dynamic modification based on the development and expansion of the existing research category of perishable goods, improve the existing theory and enrich the research content of inventory management. The above research enriches and develops the contents of traditional perishable products inventory management theory, and promote the interdisciplinary research and can provide a more realistic basis for decision-making analysis.
