【摘要】：糧食儲(chǔ)備是我國(guó)戰(zhàn)略安全極其重要的組成部分,一方面是保障國(guó)家糧食安全的頭等大事,是國(guó)家宏觀調(diào)控能力的重要物質(zhì)基礎(chǔ),是推動(dòng)經(jīng)濟(jì)發(fā)展和保持社會(huì)穩(wěn)定的必要條件。另一方面糧食儲(chǔ)備占用了大量的人力、物力和財(cái)力,需要對(duì)庫(kù)存系統(tǒng)進(jìn)行最優(yōu)控制,從而降低成本、減少資金占用量,提高效率和資源利用率,在儲(chǔ)備保障能力不下降的前提下能以最優(yōu)的成本支出來(lái)解決儲(chǔ)備糧庫(kù)存問題。從實(shí)際運(yùn)行情況來(lái)看,國(guó)家糧食安全仍面臨嚴(yán)峻的挑戰(zhàn),還存在許多問題。在宏觀方面,存在國(guó)家儲(chǔ)備規(guī)模過大、布局不合理、品種結(jié)構(gòu)不理想、儲(chǔ)備體系不完備、儲(chǔ)存費(fèi)用補(bǔ)貼不足等弊端,在微觀層面,庫(kù)存輪換方式單一、輪換成本過高、缺少儲(chǔ)備糧信息管理系統(tǒng)、內(nèi)部管理存在薄弱環(huán)節(jié),使得我國(guó)的糧食儲(chǔ)備并沒有達(dá)到理想的效果。面對(duì)糧食安全的新形勢(shì),如何既能確保國(guó)家糧食安全,發(fā)揮其應(yīng)有的宏觀調(diào)控作用,有效調(diào)控糧食市場(chǎng)和價(jià)格,又能優(yōu)化我國(guó)糧食儲(chǔ)備體系,以最優(yōu)的成本支出來(lái)儲(chǔ)備糧食是急需解決的關(guān)鍵問題。因此,以中央儲(chǔ)備糧常德直屬庫(kù)為例,對(duì)其庫(kù)存現(xiàn)狀進(jìn)行分析,結(jié)合儲(chǔ)備庫(kù)存物資的特性,分別建立符合其特征的糧食儲(chǔ)備庫(kù)存控制模型,并提出優(yōu)化措施,有很強(qiáng)的代表性和推廣價(jià)值。本文首先在查閱大量相關(guān)文獻(xiàn)的基礎(chǔ)上,對(duì)研究現(xiàn)狀進(jìn)行了分析,提出研究的主要內(nèi)容、框架思路及研究方法,闡述了庫(kù)存基本理論、儲(chǔ)備糧庫(kù)存常見模型,并分析儲(chǔ)備糧分類的要素,從重要性、響應(yīng)時(shí)間等指標(biāo),對(duì)庫(kù)存進(jìn)行分類。然后從基本情況、現(xiàn)儲(chǔ)糧庫(kù)存、附營(yíng)情況、輪換情況方面對(duì)中央儲(chǔ)備糧常德直屬庫(kù)進(jìn)行介紹,指出了中央儲(chǔ)備糧常德直屬庫(kù)存在庫(kù)存輪換方式、輪換成本、儲(chǔ)備糧信息管理系統(tǒng)、內(nèi)部管理等方面存在的問題。接著,針對(duì)不同周期、需求類型、不同分類的物資,在一定的假設(shè)條件下,分別建立符合其特征的糧食儲(chǔ)備庫(kù)存控制模型。通過設(shè)計(jì)算例,得到常德直屬庫(kù)庫(kù)存的最優(yōu)解,并對(duì)各種費(fèi)用變化、糧食儲(chǔ)備輪換量等參數(shù)進(jìn)行靈敏度分析。在此基礎(chǔ)上,找到影響庫(kù)存成本的關(guān)鍵控制點(diǎn),提出庫(kù)存優(yōu)化措施及保障機(jī)制。最后對(duì)研究成果進(jìn)行總結(jié),指出本課題研究存在的問題和不足,并對(duì)糧食儲(chǔ)備庫(kù)存研究的前景進(jìn)行展望。
[Abstract]:Grain reserve is an extremely important part of China's strategic security. On the one hand, it is the most important task to ensure national food security, is an important material basis of the state's macro-control ability, and is a necessary condition for promoting economic development and maintaining social stability. On the other hand, grain reserves take up a lot of manpower, material and financial resources, so it is necessary to control the inventory system optimally so as to reduce the cost, reduce the amount of funds occupied, improve the efficiency and the utilization of resources. The optimal cost and expenditure can be used to solve the problem of grain reserve inventory without decreasing the reserve support capacity. From the actual operation, the national food security is still facing severe challenges, there are still many problems. In macroscopical aspect, there exist some disadvantages such as the scale of national reserve is too large, the distribution is unreasonable, the variety structure is not ideal, the reserve system is not perfect, the subsidy of storage cost is insufficient and so on. At the micro level, the mode of inventory rotation is single, and the cost of rotation is too high. The lack of information management system for grain reserves and the weakness of internal management make the grain reserves in our country not achieve the ideal effect. In the face of the new situation of food security, how can we ensure the national food security, give play to its proper macro-control role, effectively regulate the grain market and prices, and optimize our country's grain reserve system? The key problem that needs to be solved is to reserve food with optimal cost and expenditure. Therefore, taking Changde directly under the central reserve of grain storage as an example, this paper analyzes the current situation of its inventory, combines the characteristics of its stock, establishes the model of grain reserve inventory control according to its characteristics, and puts forward the optimization measures. It has strong representativeness and promotion value. On the basis of consulting a large number of related documents, this paper analyzes the current situation of the research, puts forward the main contents of the research, frame ideas and research methods, expounds the basic theory of inventory, the common model of grain reserve inventory, The factors of grain reserve classification are analyzed, and the inventory is classified from the indicators of importance, response time and so on. Then, from the basic situation, the current storage stock, the attached business situation and the rotation situation, the paper introduces the central grain reserves directly under the warehouse of Changde, and points out that there exists the mode of inventory rotation and the cost of the rotation of the central grain reserve directly under the warehouse. Storage grain information management system, internal management and other aspects of the problems. Then, according to the different periods, demand types, different classification of materials, under certain assumptions, the grain reserve inventory control model is established respectively in accordance with its characteristics. Through the design example, the optimal solution of the inventory of Changde immediate warehouse is obtained, and the sensitivity analysis of various parameters, such as the change of cost and the rotation of grain reserve, is carried out. On this basis, the key control points that affect the inventory cost are found, and the stock optimization measures and the guarantee mechanism are put forward. Finally, the paper summarizes the research results, points out the problems and shortcomings of the research, and looks forward to the prospect of the research on grain reserve inventory.
