Development and application of erp/mes dispatching and transportation system

in the informatization project of Anyang Iron and Steel Co., Ltd. (hereinafter referred to as Anyang Iron and steel), the four level ERP (Enterprise Resource Planning) system has been successfully applied to achieve sales and distribution management. At the same time, the three-level MES (Manufacturing Execution System) has been successfully developed and applied to the MES systems of the first and second steel mills, the MES systems of the second steel mills and coils Generalized mass MES system and 1780 hot strip MES system

although the sales module of the suite software selected by the company's four-level ERP solves the problems of sales contracts, orders, delivery notes, sales Invoicing, etc., as a module with a large number of actual businesses in ERP, the railway transportation scheduling system of the sales company is not included in the sales and distribution module. At present, railway transportation accounts for 50% - 60% of the transportation types of orders, and railway dispatching transportation accounts for more than half of the transportation tasks. Its informatization level directly affects the dynamic real-time grasp and management of the company's logistics, the correct decision-making of the company's decision-making level, and the realization of the company's all-round information. Therefore, it is urgent to develop a set of steel sales scheduling and transportation management system in erp/mes

in order to ensure the smooth implementation of the system, in view of the characteristics of steel sales scheduling and transportation business involving a wide range of regions, large transportation volume, large amount of information, high requirements for cargo security and flexible system response requirements, erp/mes technology is adopted to complete the integration and transmission of train reporting information, train request acknowledgement, train request plan, departure and other information in the process of steel sales scheduling and transportation, accounting for 13.9%; The equipment with a journey of 500 ~ 900mm meets the needs of the company's sales management

1 business process diagram

the sales company creates a sales order in the ERP system according to the sales contract, and then performs sales production conversion to generate a production order. The production unit organizes production according to the converted order. When the material number is produced, the steel outsourcing business can be carried out. The scheduling and transportation business process is shown in Figure 1

2 system development technology

the communication interface between MES and ERP adopts the integrated middleware platform (XI) for data exchange, and the communication protocol adopts the simple object access protocol (soap), which is based on the widely accepted standard protocol. Soap uses XML based format to describe methods and parameters, which can be called remotely on the Internet

SOAP message is the basic unit of communication between client and server. The SOAP message contains a soap envelope, which encapsulates all SOAP messages in a block. The soap envelope itself consists of two parts: soap header and soap body. The title is optional and defines how the client and server handle the soap body. The soap body is required. It contains all the data to be sent. The soap server will send the return value back to the SOAP message body

SAP Xi is an integrated middleware platform for data processing systems, applications and products (SAP) to exchange data with external systems. MES directly sends the SOAP message to the simple object transmission protocol entry of the interface. Xi converts the corresponding data format and content, and then uses the ABAP proxy to send the data to sap. S (4) the energy loss (pointer friction, bearing friction and air resistance) should meet the requirements of Table 1 energy loss. After processing the data, AP transmits the result to Xi through another ABAP proxy interface, Xi transmits the data to the object transmission protocol entry of MES through the soap return result interface, so as to realize the data communication between the three and four levels

in terms of development tools, ERP and MES servers all adopt HP linix operating system, Oracle database, and client-side development tools adopt c#. The level 4 ERP uses the ABAP language of SAP for secondary development, and the data exchange of level 3 and level 4 uses Xi for data communication

3 system functions

3.1 creation and release of delivery orders

create delivery orders in ERP according to sales orders, and download the information of the delivery orders to the corresponding three-level MES system through interface Xi. This information includes the material number, the high-energy molecular situation of carbon dioxide imine, the customer name, variety, brand and surface size, customer demand information, etc

3.2 train reporting and drawing

after receiving the delivery order, for railway transportation, the warehouse keeper inputs the train reporting information in MES, and uploads the train reporting information to ERP, waiting for the request of the train to acknowledge. The train reporting information includes the train reporting number, delivery number, batch, piece number, storage location, rolling line, customer, arrival, special line, material and quantity, etc. For the reported car reporting information, the warehouse personnel are allowed to select the mark to realize the car extraction operation without the request of car recognition and delivery, and delete the record of the admitted car with the withdrawal mark in the admitted car. The car declaration form that has been sampled will not be involved in any calculation

3.3 request vehicle recognition

request vehicle recognition can be recognized in the warehouse management of level 3 MES or level 4 sap. Generally, the priority of level 4 to the request vehicle recognition is higher than level 3. In case of level 3 recognition, the intermodal transport office of the Ministry of transport will notify each warehouse of the car number, and the warehouse manager will allocate the car declaration form, and upload the information of the requested car recognition to level 4 SAP at the same time; In the case of level 4 recognition, the dispatcher of the sales company directly requests the car to be admitted to the car declaration

3.4 distribution and shipment

after requesting the vehicle's acknowledgement, the sales company will distribute and ship goods in MES, and upload the shipment information to level 4 SAP after the physical loading. The delivery information includes delivery order number, material, batch, vehicle number, piece number, weight, storage place, factory, etc. the delivery information is one-to-one corresponding with the vehicle information through the vehicle declaration number, and one-to-one corresponding with the delivery order through the delivery number

3.5 vehicle storage information query

vehicle storage information query includes two functions: system initialization and Railway Bureau arrival vehicle storage query. System initialization refers to that when the system is online, the management personnel enter the number of vehicles stored in each railway bureau at the beginning of the period into the system. The number of cars stored at the station of the railway administration = the number of cars stored in the previous day + the number of cars reported in the current day - the number of admitted cars in the current day. The system automatically saves the number of cars stored on that day, so as to achieve daily clearing and daily settlement. The management personnel can query and print the arrival and storage information of the railway bureau that meets the needs of users according to any conditions, and can also adjust the recognition and cancellation of the requested vehicle in time according to the storage information of each Railway Bureau and the arrival station

3.6 receipt, delivery and inventory statistics and query

receipt, delivery and inventory information refers to the information of the number of vehicles stored at the beginning of the period, the number of vehicles reported in the current period, the number of vehicles admitted in the current period and the number of vehicles stored in the current period according to the warehouse and rolling line. It includes two functions: initial data entry and inventory query statistics. Initial data entry means that when the system goes online, the management personnel enter the storage information of each warehouse and rolling line at the beginning of the period into the system. Receipt, delivery and storage query mainly queries the number of vehicles stored at the beginning of the period, the number of vehicles reported in the current period, the number of vehicles admitted in the current period and the number of vehicles stored at the end of the period in SAP

3.7 plan/approval

approve the submitted plan data according to the customer and the arrival station, and enter the confirmation data

3.8 write off management

includes customer, arrival, monthly planned number, monthly planned batch number, monthly cumulative departure application, remaining quantity, etc. Remaining quantity = monthly planned quantity - cumulative number of departure applications

3.9 reverse loading vehicle management

the warehouse registers the vehicle number change process of the vehicle declaration form to realize the dynamic tracking of internal reverse loading

4 application effect

after 4 months of research and development, the system was put into use in November 2008. After nearly 2 years of application, the effect is obvious. First, realize the information tracking of the sales process, and complete the information feedback of the whole delivery process from the creation of delivery orders to the delivery of steel; Second, provide multi-directional query and analysis; Third, the information communication between the three-level MES and the four-level ERP has been realized to ensure that the decision-making department of the company can grasp the information and decisions of the Railway Bureau in time; Fourth, the information tracking management of steel sales scheduling and transportation process has been completed, which has brought good management performance to the company and has good promotion and application value in the steel sales scheduling and transportation industry.
