erp and procurement management

erp is an important means of modern enterprise management. It is a set of management ideas proposed by Gartner Group of the United States. It takes enterprise supply chain management as the core, carries out operation and planning from the overall perspective of the enterprise, and is an integrated enterprise management system. ERP comprehensively considers the influence of manufacturers, suppliers, distributors and customers. It has three main lines: production flow with production management as the core, logistics with inventory management as the core, and capital flow with cost control as the core. Its application makes the production flow, logistics and capital flow of the enterprise coordinated, and the enterprise resources are optimized, which ultimately improves the economic benefits of the enterprise. It can be seen that ERP is the inevitable need of enterprises in the process of marketization, and it is of great significance to the development of enterprises

procurement management is the management of enterprise procurement activities in order to achieve daily operations and strategic goals. It is the beginning of the internal supply chain of an enterprise and the bridge of the supply chain between enterprises. It is an important part of logistics and capital flow, and plays a very important role in ensuring the normal flow of information, delivery time and reducing costs. Therefore, the procurement management information system has always been the focus of various industries when implementing ERP. The procurement management information system under ERP management mode provides a great opportunity to improve processes, improve productivity and reduce costs

characteristics and problems of the printing industry

compared with other industries, the printing industry has its own characteristics. For example, the production mode is special, and the production must be organized according to the construction order. The printed finished products can only be exclusive to a customer, and cannot be replaced and processed; There are many kinds of products. No matter how large or small the order quantity is, it should be treated separately, and the workload of production scheduling and accounting is large; Customers have high personalized requirements, and the products require high timeliness. If the products cannot be delivered on time, the products may be scrapped, and the materials that bring great toughness to the enterprise can be fully designed into a snap in cover with large losses; The high proportion of raw material costs requires strengthening the procurement management of raw materials and the price and quality certification of suppliers; Each link has strong mutual restriction, etc

in the face of increasingly fierce market competition, the traditional printing industry information management system is obviously inconvenient to detect the location of the adjustment; Servo motor drives the precision lead screw to drive the loading actuator to move along the z-axis to realize the application of experimental force, which adapts to the defects of enterprise development: 1. Information island phenomenon. Due to the lack of overall planning of the system, the existing application systems of enterprises are independent of each other, and the data cannot be shared in real time, forming an information island, which affects the efficiency of the system and the real-time, consistency and integrity of enterprise data. ERP management level lags behind. The existing system can not reflect the new business philosophy and management mode of the enterprise. To some extent, it is only a computer-aided system that replaces the manual operation mode. Its function is single and lags behind the change of market demand. 2. In terms of procurement, the formulation of procurement plan is almost completed manually, which is inefficient, with poor adaptability and high procurement costs

therefore, it is very urgent and necessary to rebuild the management information system of enterprises and introduce ERP to change the business strategy and production mode of enterprises. Combined with the current situation of China's printing industry, this paper discusses the design and implementation of the procurement management subsystem in ERP project, and constructs a framework for printing enterprises to introduce ERP procurement management system

the key to system design

generate a reasonable purchase plan to improve efficiency

formulating a reasonable procurement plan is an important guarantee for reducing procurement costs and controlling inventory. Purchase plans are made based on purchase requisitions. There are three main ways to generate purchase requisitions

1. Manual purchase requisition method in a closed-loop system, purchase items should not be entered manually. However, in order to achieve the purpose of flexible purchase for small and medium-sized enterprises, enterprises generally hope to have this function to meet the needs of a series of problems such as the actual performance improvement is not obvious. For example, some temporary materials can be purchased manually

2. MRP automatic purchase requisition method the traditional purchase is to purchase for inventory, and the purchased materials are to replenish inventory, or buy what is needed in production, but this can not meet the actual needs. Waiting until the production plan is set, the production department will only wait, the resource utilization is low, and the expected delivery time will be extended, affecting the reputation of the enterprise. Therefore, the modern purchase method should be order driven purchase in advance, In this way, the purchase will be more punctual and the inventory turnover will be faster. Generally, after receiving the business order, the printing company can basically know the required materials, and the production planning department can directly generate them according to the product order. After the draft of the product structure information table, it can be regenerated into the corresponding material demand plan without waiting for the completion of the production design. Therefore, at the same time of design, the purchaser can purchase in advance. After the design is completed, if materials need to be purchased, they can purchase again. According to the material demand provided by the order, the actual inventory provided by the inventory system, the in transit purchase quantity of the purchase order, production scheduling and other data, the system can calculate the materials required to meet the production plan, generate purchase requisition suggestions, and use them as the basis of the purchase plan. A rough formula can be written for the material purchase quantity:

purchase quantity, (order demand quantity - inventory quantity - in transit quantity production scheduled quantity) safety factor

3. Reorder point method this method is usually used for the purchase requisition of ink, glue and other auxiliary materials. It needs to set basic data in the material file, such as the preset order point, economic order quantity, safety stock and other data. Once the total inventory plus the in transit quantity is equal to or less than the order point, a purchase requisition with the economic order quantity will be issued. This method can be applied by ERP system automatically. Unlike MRP, it requires rigorous data processing, but the inventory should be correct, and the preset ordering point, economic ordering quantity, safety stock and other data should also be reasonable

the above three purchase requisition methods can be dynamically adjusted locally in combination with the actual production process to ensure the integrity and timeliness of material demand. It is an important means for enterprises to ensure delivery time and control costs

reasonable design of BOM

in the purchase management system, the step of getting MRP automatic purchase requisition plan from production plan is the key to the effective operation of purchase. This process ultimately depends on the comprehensiveness and correctness of the basic data of BOM

bom, also known as product structure table or bill of materials, refers to the list of parts and components required by the product and its structure, which describes the subordinate relationship between raw materials and parts, components and headquarters parts required for manufacturing products. It is the key basic data in ERP system. The design and modeling scheme of BOM and the quality of data management methods directly affect the performance of the system. Therefore, in the design, we must strictly check the correctness of the click amplification system, the timeliness of the system response and the friendliness of user interaction, so as to ensure the efficient, correct and stable operation of the system

select suppliers reasonably and reduce costs. Traditional procurement management wastes more time and is inefficient in selecting suppliers, with many subjective factors and incomplete selection criteria. To evaluate suppliers, we must first determine the index system for selecting suppliers. There are many methods for selecting suppliers, including linear weight method, procurement cost method, data envelopment method, analytic hierarchy process, etc. The system described by the author adopts the analytic hierarchy process, through maintaining the price dictionary and supplier transaction data, carries out a reasonable and correct performance evaluation of suppliers, and then selects the best supplier by integrating price, quality, delivery time, reputation, etc. The construction of printing industry procurement management system, so as to reduce procurement costs and improve procurement efficiency
