The emergence of closed-loop MRP systems has enabled all kinds of subsystems in production activities. But this is not enough, because in the management of the company, production management is only one aspect, and it is only logistics, and there is also a funds related to logistics. This is also managed by the accounting personnel in many companies, which causes the data to be repeatedly entry and stored, and even the data is not unconnected.
Therefore, in the 1980s, people set production, finance, sales, engineering technology, procurement into a integrated system, called manufacturing resource plan, English abbreviation or MRP, in order to Different logistics demand programs (also abbreviated as MRP), which is recorded as MRP II.
1. Principles and logic of MRPI
The basic idea of MRPI is to use the company as an organic overall, from the overall optimal perspective, through the use of scientific methods for various manufacturing resources and production, supply, sales, and all aspects of the enterprise to effectively plan, organize and control, They were coordinated and fully played. The logic flow chart of MRPI is shown in Figure 1.
Figure 1 MRPI logic flow chart
On the right side of the flowchart is the process of planning and control, which includes the decision layer, the plan layer, and the control execution layer, which can be understood as the process of business plan management; the intermediate is the basic data, stored in the computer system, and Repeated call. The integration of these data information, communicating into the business of the enterprises, can be understood as computer database systems; the left side is the main financial system, which lists only accounts, generals, and payable accounts. Each link indicates the flow of information and the integration relationship between each other.
2. MrPI management model features
The characteristics of MRPI can be described in the following aspects, each feature contains two aspects of the management model and the quality or behavioral change, which is complementary.
1. The consistency and feasibility MRPII is a planned dominant management model, the plan level from macro to micro, from the strategy to technology, is optimized by coarse to layright, but always guarantees the consistency of the business strategy. It consists of the usual three-level plan management, planning to prepare work is concentrated in the factory-level function department, and the workshop team can only perform plans, scheduling, and feedback information. The plan will be repeatedly verified and balanced, and the feedback information is adjusted according to the feedback information, handle the contradiction, effectiveness, and executability of the plan.
2. The systemic MRPII is a system engineering that combines all the work of the company directly related to the production and operation of the relevant departments into a whole, and all departments have made their own work from the system, and each employee knows their work quality. The relationship between other functions. This can only become a system, block segmentation, and all rows should be replaced by team spirit.
3. Data sharing MRPI is a manufacturing enterprise management information system. Enterprise departments are managed by the same data information. Any data change can be reflected in time to all departments, and data sharing is achieved. Under the support of the unified database, manage and decisions according to the standardized handler. Changed the kind of information in the past, unknown, blind decision, conflicting with each other.
4. Dynamic strainming MRPI is a closed-loop system that requires tracking, control and feedback of the actual situation of rapid change, and managers can respond quickly according to the changes in environmental conditions inner and external environment, and ensure normal production. It can keep various dynamic information in time, maintain a shorter production cycle, and there is a strong strain ability.
5. The analog predictability MRPI has analog function. It can solve the problem "if it is ...", it is foreseen that may happen in a considerable planning period, take steps to eliminate hidden dangers in advance, rather than other problems have taken a few times energy to process . This will enable managers to free from busy transaction stacks, dedicated to substantive analysis and research, providing multiple feasible programs for leadership decisions. 6. Logistics, the unified MRPI in the fund flow contains cost accounting and financial functions, which can directly generate financial data directly, directly convert the physical flow of the physical form into the fund flow of value forms, and ensure the consistency of production and financial data. The financial department is timely fund information for controlling costs, reflects material and business conditions through capital flow conditions, and analyzes the economic benefits of enterprises, participate in decision-making, guiding and controlling operations and production activities.
The above aspects of the above aspects show that MRPI is a relatively complete production and management plan system, which is an effective management model for achieving the overall benefits of manufacturing enterprises.
