【摘要】：對于制造企業(yè)來說，庫存成本在生產(chǎn)成本中所占比重很大，如何有效的通過控制庫存策略來降低庫存成本，對于企業(yè)來說有很重要的實際意義。 本文主要研究的是制造企業(yè)庫存成本的最優(yōu)控制策略。該問題有有限個計劃周期，各計劃周期內(nèi)的需求服從離散分布，目標(biāo)是尋找一種最優(yōu)庫存控制策略，使得計劃周期內(nèi)的庫存成本（運輸成本、庫存持有成本和缺貨懲罰成本之和）最小。 本文以(s, S)庫存策略作為基礎(chǔ)，結(jié)合制造企業(yè)的實際情況，建立了三個庫存策略模型，分別是均衡(s, S)庫存控制策略模型、動態(tài)(s, S)庫存控制策略模型和倉儲空間有限的庫存控制模型。均衡(s, S)庫存控制策略模型是在一個計劃周期內(nèi)，所有的階段采取同一組(s, S)補貨策略；動態(tài)(s, S)庫存控制模型是在一個計劃周期內(nèi)，所有的階段可以采用不同的(s, S)補貨策略，是均衡(s, S)庫存控制模型的推廣。這兩種庫存控制策略模型都包括三種不同的庫存策略：嚴(yán)格(s, S)庫存策略、帶參數(shù)r的(s, S)庫存策略和選擇性執(zhí)行(s, S)庫存策略。帶參數(shù)r的(s, S)庫存策略是在嚴(yán)格(s, S)庫存策略的基礎(chǔ)之上增加參數(shù)r控制運輸車輛數(shù)，相對于嚴(yán)格(s, S)庫存策略更具有實際意義；選擇性執(zhí)行(s, S)庫存策略是對帶參數(shù)r的(s, S)庫存策略的一種推廣：通過狀態(tài)“0”、“1”控制每個階段是否需要補貨。倉儲空間有限的庫存控制模型，是在企業(yè)的倉儲空間不能滿足所有零件同時補貨的情況下，如何對零件安排有效的補貨策略，使得總庫存成本最低。 對于每種庫存策略，，都有相應(yīng)的算例描述和實例分析，通過對實例的數(shù)值分析可以得出：合理的選取補貨策略，可以顯著的降低庫存成本。
[Abstract]:For manufacturing enterprises, inventory costs account for a large proportion of production costs, how to effectively control inventory strategy to reduce inventory costs, for enterprises to have a very important practical significance. This paper mainly studies the optimal control strategy of inventory cost of manufacturing enterprises. The problem has a limited number of planning cycles, and the demand for each planning cycle is distributed from discrete to discrete. The goal is to find an optimal inventory control strategy so that the inventory cost (transportation cost) in the plan cycle, The sum of inventory holding cost and shortage penalty cost) is the smallest. Based on (s, S) inventory strategy and the actual situation of manufacturing enterprises, this paper establishes three inventory strategy models, which are equilibrium (s, S) inventory control strategy model. Dynamic (s, S) inventory control strategy model and inventory control model with limited storage space. The equilibrium (s, S) inventory control strategy model adopts the same (s, S) replenishment strategy in all stages of a planning cycle, while the dynamic (s, S) inventory control model is used in a planning cycle. Different (s, S) replenishment strategies can be adopted in all stages, which is the generalization of equilibrium (s, S) inventory control model. The two models of inventory control strategy include three different inventory strategies: strict (s, S) inventory strategy, (s, S) inventory strategy with parameter r and selective execution of (s, S) inventory strategy. The (s, S) inventory strategy with parameter r is to add parameter r to control the number of transport vehicles on the basis of strict (s, S) inventory strategy, which has more practical significance than strict (s, S) inventory strategy. Selectively executing (s, S) inventory policy is a generalization of (s, S) inventory policy with parameter r: through state "0", "1" controls whether replenishment is required at each stage. The inventory control model with limited storage space is how to arrange effective restocking strategy to make the total inventory cost lowest when the storage space of the enterprise can not satisfy all the parts replenishment at the same time. For each inventory strategy, there are corresponding example description and case analysis. Through the numerical analysis of the case, it can be concluded that reasonable selection of replenishment strategy can significantly reduce the inventory cost.
