I. Introduction

In today's digital era, the competition of enterprises is becoming more and more intense, and efficient material warehouse management plays a crucial role in controlling the operating costs, improving production efficiency and increasing customer satisfaction. Traditional warehouse management methods, such as manual inventory records, manual inventory, etc., not only inefficient, error-prone, and difficult to meet the growing business needs of enterprises. Intelligent warehouse management system came into being, which integrates advanced technologies such as Internet of Things, big data, artificial intelligence, etc., and brings a brand-new solution for the digital management of enterprise material warehouse, aiming to improve management efficiency, reduce costs, optimize resource allocation, and thus enhance the core competitiveness of enterprises. In this paper, we will discuss the application of intelligent warehouse management system in the enterprise digital material warehouse management, advantages, implementation cases, as well as the challenges and response strategies.

Second, the current situation and problems of enterprise material warehouse management

(i) Disorganized stockpile management

1. Inaccurate inventory dataIn traditional material warehouse management, inventory data mainly rely on manual recording and updating. In the process of material in and out of the warehouse, due to human negligence, untimely recording and other reasons, often lead to inventory data and the actual number of inventory does not match. For example, employees do not register in time after receiving materials, or there are errors in data entry, so that the inventory system shows the number of deviations from the actual number of warehouses, which brings great trouble to the enterprise's production planning and purchasing decisions.
2. Inventory backlogs and stock-outs go hand in handDue to the lack of accurate inventory data and effective demand forecasting, enterprises often experience the contradictory phenomenon of inventory backlogs and stock-outs. On the one hand, certain materials have been backlogged in the warehouse for a long time due to over-purchasing, occupying a large amount of capital and storage space; on the other hand, some key materials are not replenished in a timely manner, leading to production interruptions and affecting the normal operation of the enterprise. This irrationality of inventory management seriously restricts the development of enterprises.

(ii) Operational inefficiencies

1. Cumbersome warehousing processIn the traditional warehousing process, staff need to check, accept and register each batch of materials one by one, and then arrange the storage location. This process involves a lot of manual operations and paper handling, which is not only time-consuming but also prone to errors. For example, when checking the quantity and specifications of materials, it may result in storage errors due to manual miscalculation or misreading of documents.
2. Slow outbound processWhen leaving the warehouse, the staff need to look for the corresponding materials in the warehouse according to the order, and it often takes a lot of time to look for the materials due to the irrational layout of the warehouse or unclear marking. Moreover, in the process of material handling, it may also be due to backward equipment, lack of manpower and other reasons leading to inefficiency in the warehouse. In addition, manual filling out the warehouse receipt and other operations also increase the probability of error.

(iii) Poor communication of information

1. Intersectoral information barriersThere is often a problem of poor information communication between different departments within an organization, such as the purchasing department, the production department, and the warehouse management department. Each department uses an independent information system, data can not be shared in real time, resulting in information lag or inconsistency. For example, after the purchasing department has placed a purchase order, the warehouse management department cannot obtain the order information in time and cannot prepare to receive it in advance; changes in the demand for materials by the production department cannot be communicated to the warehouse in time, which may lead to under or over-preparation of inventory.
2. Difficulty in interacting with supplier informationThere are also many inconveniences in the information interaction between enterprises and suppliers. The traditional way of communication mainly relies on telephone, e-mail, etc., which is inefficient in information transfer and prone to information omission or misunderstanding. For example, in the process of material replenishment, the enterprise issued replenishment demand to the supplier, it is unable to real-time tracking of the supplier's stocking progress and delivery, which may affect the normal production of the enterprise.

(iv) Inadequate data analysis and decision support

1. Difficulties in data collectionIn the traditional way of material warehouse management, data are scattered in various links and are difficult to collect. For example, inventory data, inbound and outbound data, and equipment operation data are recorded in different paper documents or independent spreadsheets, making it difficult to integrate and analyze. Moreover, the process of manual data collection is not only time-consuming and laborious, but also prone to data errors.
2. Lack of decision supportDue to the lack of effective data analysis, enterprise management in the development of warehouse management strategy, optimize inventory structure, adjust the warehouse layout and other decisions, often lack of scientific basis, can only rely on experience to make judgments. This way of decision-making may lead to decision-making errors, and can not give full play to the operational efficiency of the warehouse.

Third, the principle and composition of intelligent warehouse management system

(i) System principles

Intelligent Warehouse Management System is based on Internet of Things (IoT) technology, which realizes all-round digital management of the material warehouse by installing all kinds of sensors and intelligent devices in the warehouse as well as adopting advanced software algorithms.
