What are the factors that affect the MRP planning process

1. Plan lead time.

2. Batch size specifications.

3. Safety stock.

The basis and basic principle of MRP is to convert the product delivery date into the production schedule of parts and components, the required quantity and demand date of raw materials and purchased parts, that is, to convert the product production plan into a material demand table, and provide information for the preparation of capacity demand plan.

According to the subordinate and quantity relationship of items at all levels of product structure, each item is taken as the planning object, the completion period is used as the time benchmark to reverse the plan, and the order of the planned time of each item is distinguished according to the length of the lead time, which is a material planning management mode in an industrial manufacturing enterprise.

MRP is based on market demand** and customer orders to develop the production plan of the product.

Then, based on the product to generate a schedule, the material structure table and the inventory status of the product, through the computer to calculate the demand for the required material and the demand time, so as to determine the processing progress of the material and a practical technology of the order schedule.

1. From the production plan of the final product.

Independent Requirements) derives the required quantity and demand time for related materials (raw materials, components, etc.).

2. Determine the time to start production (order) according to the demand time of the material and the production (order) cycle.

MRP, Chinese name "material requirements plan". That is, according to the subordination and quantity relationship of items at all levels of product structure, each item is taken as the object of bending and high fiber planning, the completion period is used as the time benchmark to reverse the plan, and the order of the plan time of each item is distinguished according to the length of the lead time, which is a material planning management mode in an industrial manufacturing enterprise.

The basic tasks of MRP: 1) From the production plan of the final product (independent demand) to guide the demand and demand time of related materials (raw materials, parts, etc.). 2) According to the demand time of the material and the production (order) cycle to determine the time of the start of production (order) in the opening track.

Today I just saw that I have space, welcome to visit.

Summary. Hello, dear, glad to answer for you! MRP only considers the material needs of the production enterprises themselves, if there is no shortage of materials, raw materials at the same time as little as possible to occupy inventory and inventory funds; Later, in the process of gradually developing to ERP, gradually consider the upstream and downstream factors, not only consider the problem of processing materials, but also join part of the content of the first business management, SCM, customer resources and customer relationship management CRM in the chain, so that the production information and the company's capital information can be opened from the internal closed cycle.

What are the main drivers in the evolution from MRP to ERP?

Hello, dear, glad to answer for you! MRP only considers the material needs of the production enterprises themselves, if there is no shortage of materials, raw materials at the same time as little as possible to occupy inventory and inventory funds; Later, in the process of gradually developing to ERP, gradually consider the upstream and downstream factors, not only consider the problem of hungry search for their own processed materials, but also add part of the content of the first business management, SCM, customer resources and customer relationship management CRM in the chain, so that the production information and the company's capital information can be opened from the internal closed cycle.

In this process, the production mode has gradually undergone several changes: 1) closed production gradually moves towards an open mode of coordinated production, considering the supply and sales of upstream and downstream; 2) Pay attention to customer experience and after-sales feedback while producing, so as to adjust R&D and improve production in a timely manner; 3) From inefficient production of goods to large-scale production of goods, reduce internal consumption and costs, shift to adjust production and supply according to market and customer needs, and flexible production to meet the more and more personalized needs of customers; From making and then selling to producing according to order or adjusting while producing;

4) To go further, to achieve just-in-time production, not only their own production department but also the first business delivery batch time, the number of sales to customers, the time have been considered, so that how to pay for funds, how to collect, how to adjust production inventory, transportation methods, customer information adjustment and gradually improve the ability to collect and control. JIT is produced just-in-time. While forming production, all aspects of capital flow and information flow are considered.

5) If it is bigger and stronger to a certain extent, predict the market according to customer feedback in advance, take the initiative to initiate production, and then guide and meet the needs of customers. Lean production, control the current product, the future product within the whole life time range, all production, transportation, labor and all factors. For example, Apple's mobile phone meets many needs of customers, so it provides a mobile phone like Apple, rather than waiting for customers to develop after they have needs.

Material requirement planning (MRP) refers to the subordination and quantity relationship of items at all levels of product structure, taking each item as the planning object, taking the completion period as the time benchmark to reverse the plan, and distinguishing the order of the planned time of each item according to the length of the lead time, which is a material planning management mode in an industrial manufacturing enterprise.

Material Requirements Planning (MRP) is believed to be familiar to many students who have studied managementIt is a professional term for management (in which operations management). Material requirements planning originated in the United States in the 60s of the 20th century, mainly to solve the management problems of industrial production. The importance of MRP for production management is still significant todayIt is also one of the learning difficulties for management students.

Next, I will briefly introduce the concept of material requirements management and its basic components.
