How has the enterprise machine program evolved?

The evolution process of the enterprise and the plan is to effectively plan the focus and detailed content of the entire enterprise, and then effectively manage it according to the plan and implementation measures, which is one of the main processes of its evolution.

MRP (Material Requirement Planning) is a material requirement planning system with material planners or inventory management personnel as the core, and its scope is only for material management.

Working principle: According to the different needs, the materials within the enterprise can be divided into two types: independent demand and related demand. Independent demand refers to the demand quantity and demand time determined by the external demand of the enterprise, and the related demand refers to the demand generated by the independent demand of materials according to the structural composition relationship between materials, such as the demand for semi-finished products, parts, raw materials, etc.

MRPII (Manufacturing Resource Planning) is a complete set of production and operation management planning system for effective planning of production resources of manufacturing enterprises, and is a plan-oriented management model.

Working principle: MRPII is an integrated system that integrates the production, finance, sales, procurement, technical management and other subsystems of the enterprise, and each part is interconnected and provides data to each other. It can carry out comprehensive control and management of business activities.

It is divided into 5 layers: 1 business plan.

2. Production plan outline, resource demand plan.

3. Master production plan, coarse capacity plan.

4. Material requirement planning, capacity requirement planning.

5. Workshop production control.

Develop relationships. MRPII is a direct extension and expansion of closed-loop MRP, which is based on the comprehensive inheritance of MRP and closed-loop MRP, and integrates the business planning, sales and distribution, procurement, manufacturing, finance, cost, simulation functions of enterprise macro decision-making, and multi-language, multi-currency, multi-tax and computer-aided design (CAD) technical interfaces to meet the needs of international business, forming a comprehensive production management integrated system.

ERP is Enterprise Resource Planning, which unifies the logistics, capital flow and information flow of the enterprise for management, in order to maximize the use of the existing resources of the enterprise and maximize the economic benefits of the enterprise.

Features: 1) Integration of the value chain;

2) consistency and reliability of the plan;

3) systematization;

4) data sharing;

5) dynamic strain;

6) Simulation predictability.

7) The unification of logistics, capital flow and information flow.

Working principle: The working principle of ERP is to integrate resources and connect each process, so as to enable enterprises to achieve the highest operational efficiency.

Relationship development: Compared to a standard MRP system, the extended capabilities of ERP include quality management, laboratory management, process operation management, recipe management, product data management, maintenance management, regulatory reporting, and warehouse management. In fact, ERP is still based on MRP, but these functions are integrated with the ** chain, focusing on decision support and customer relationship processing.
