Illustratively, viewed in data flow, it can be divided into sales channels, factory production and raw material procurement.
The management system mainly comprises three parts: distribution channel unit, factory production unit and purchase unit
Firstly, setting in a distribution channel unit: a salesman shop patrol module; a distribution management module; order & storage & transportation management module;
the salesman shop patrol module is used for establishing shop patrol routes according to regional customer information, wherein the regional customer information comprises but is not limited to sales volume, respective sales regions, number and distribution of shops, distance among cities and traffic information. In order to improve the efficiency of supervision and to maximize the number of daily visiting customers, i.e. stores, standardized by the staff. Thereby reducing the cost. The system has unified tour standards, supervisors set tasks, can place a goods demand list when arriving at a store, count goods in the store, adjust target inventory and the like, and obtain the latest order information and inventory information of the store in real time.
Through the classification planning guidance in the distribution management module, in the exemplary embodiment, the classification planning guidance adopts an ABC classification method to classify goods, and helps a sales department to accurately position the selling of suitable single goods every other shop. For example, about 2000 products, after the ABC classification, the A class and the B class generally do not exceed 50 products, and a buyer of a purchasing department can focus on key products for sale, so that the availability of the products is ensured.
Meanwhile, data analysis such as ADU alarm, SKU inventory monitoring, purchase replenishment suggestion, TDD analysis, inventory availability, inventory turnover times, product movement and marketing analysis and effective output analysis are matched.
And a pull type replenishment mode is used, so that new products are paved on the market, the market is moved, the analysis is carried out, and the effective output is realized.
Secondly, producing the unit in a factory:
constructing a new production operation model with the purpose of ensuring reliability and reaction capability to realize an elastic manufacturing system
And introducing an actual driving type production command signal model.
1, constructing a strategic buffer system for eliminating the bullwhip effect;
specifically, selecting a buffering object material, determining a strategic buffering point, and planning an optimal ordering strategy based on product characteristics on the basis of a statistical method;
specifically, the ABC classification calculation (rule two eight) is performed according to commodity value and sales achievement, which is as follows: the inverted rows are sold and scored with percentages. 60% of the products belong to A class, 60% -90% of the products belong to B class, and the others belong to C class, the A class of hot-sell products have large demand and small time interval difference and belong to smooth demands, and conversely, the C class of products have irregular or occasional demand due to demand fluctuation;
analysis of demand volatility: time series data analysis, covariance (CoV) time interval x number difference;
high value goods are assembled in production/order and a simple spot order or double box method is used to determine low value goods for batch production.
If daily demand volatility (Cov) is considered from the demand volatility, and the sales volume ABC classification method is added, demand driving can be realized. According to a DDOM (demand drive Operation model) demand-Driven Operation model, performing on-demand replenishment, demand-Driven/balanced replenishment and event management;
increasing the service level over a time tolerated by the customer;
the requirement visualization interval is as follows: the demand time from order placement to delivery can be achieved without prediction if the interaction period can be shorter than this period.
The combination of the stock leverage effect and the flexibility effectively adjusts the amount of the universal materials and the universal components.
Internal and external volatility: mainly considering the bullwhip effect in the supply chain, etc. Exemplary division into a demand side and a supply side.
And preparing the materials according to the sleeve aligning points set according to the sleeve aligning requirement.
Specifically, a target inventory is constructed to establish a buffer water level;
