Understand the production scheduling management function of MES system

MES Management system Production scheduling refers to production scheduling based on job 、 Order 、 Batch 、 Manage the material flow or information flow in the production unit in the form of batch and work order . When an event occurs in the workshop , This unit needs to carry out certain processing work in real time .

This processing must be carried out according to certain constraints , Scheduling information is the sequence of tasks arranged according to these constraints . Production scheduling can adjust the specified plan of the factory workshop , Dispose of repaired products and waste products , Use buffer management method to control the quantity of WIP at each point .

Although many enterprises are ERP The production plan is made in the system , but ERP The plan of the system is a high-level plan , It is impossible to schedule the production of a specific production work order between operations .

MES Production management system Production scheduling module , The production work order can be scheduled automatically and manually , Arrange each work order in the specific production line of each process 、 And according to the information provided by the warehouse management module , Inspection . After scheduling , Positions 、 Roles can query production scheduling information in the system , And arrange the work according to the production schedule .

MES System production scheduling business process

1. Order download of production scheduling

MES System from ERP Download the production order of nearly a week in the system , stay MES Generate production work order in . During download , The system processes the standard process path corresponding to the product according to the work order , Generate operation information and parameter information of each operation of the current work order . The system provides manual and automatic modes .

The manual download method will be based on the manually entered work order number ERP The information in the system is downloaded and written to production MES System In information , And set the work order status of the material to be produced .

When the status of the source work order information does not meet the download requirements, the system prompts the operator . Automatic download mode ： Time scan ERP Work order information in the system , Search for work orders that have not been downloaded , When the conditions are met, the system will automatically download the work order to MES In the system, the material work order status is set to ready for production .

2. Production scheduling order entry

MES The system allows you to manually enter non ERP Order in , The entered order is the same as ERP The process and management of the downloaded order in the subsequent processing process are the same .

3. Production scheduling work order maintenance

from ERP Downloaded order generation MES Software After your work order , Only the wo processing information of the current order is generated , Did not consider some special circumstances . Through the work order maintenance function , You can adjust the work order .

（1） Three aspects of production scheduling work order adjustment ： First, the information of single workers , The second is the processing process path of the work order , Third, in each processing process path , Some specific production process control 、 Quality inspection method 、 Setting and adjustment of parameters such as production quality early warning .

（2） Production scheduling work order information maintenance mainly includes work order number 、 Processed products 、 Planned production quantity 、 Planned commencement date 、 Maintenance of planned completion date and other attributes .

（3） Operation information maintenance mainly includes the processing operations of products （ Can increase 、 Insert 、 Delete ）, The control and quality control required by the production process can be set for each process . For unfinished work orders , Sure （ modify 、 Increase or decrease ） Planned production quantity , Carry out additional production or complete production ahead of schedule . For the operation work order that has not been started , You can delete or change .

4. Production scheduling work order scheduling

Production scheduling enables the dispatcher to optimally arrange the processing of work orders in each process with the help of computer system , Ensure timely delivery , At the same time, ensure the highest utilization rate of the production line , Arrange the work order to each operation 、 Continuous and effective production on each line body .

The system provides two operation modules: automatic scheduling and manual scheduling , Automatic scheduling is based on the process path of the work order to be scheduled 、 Equipment capacity 、 Running state 、 Staffing and other factors , Automatic optimization , Find the scheduling result of suboptimal solution . Manual scheduling uses an interactive graphical interface , Easy to operate 、 intuitive .

The processing time of an operation in the work order is based on the machine efficiency of the product operation 、 The batch size of the work order 、 The transfer time setting and other conditions are automatically calculated , It simplifies the labor of dispatchers , Improved production scheduling efficiency . Manual scheduling can adjust the results of automatic scheduling . The results of production scheduling are displayed in two ways: table and Gantt chart .

5. Production scheduling complete set inspection

The processing sequence of each work order determined according to the work order scheduling , At the same time, according to , Current inventory of raw materials , According to the bill of materials of the work order , Pre check the completeness of raw materials in each work order one by one , And it is represented by color discrimination in the result graph of production scheduling , Make the plan clear about the production capacity and materials of the whole production , Reasonably arrange relevant production activities .

6. Release the production scheduling results

After scheduling , Through the results, all authorized positions 、 Characters can be in Production management system Production scheduling information is found in , And arrange the post work according to the information .

MES Function of system production scheduling

1. Ensure the smooth operation of the production process

Prepare production plan and production operation plan , No matter how carefully considered , It is also impossible to foresee the changes in the actual production process . In the actual production process , The complicated , the myriads of changes , There are local , There is also an overall ; There are internal , There are also external ; There are technical , There are also equipment ; There are subjective factors , There are also objective factors .

These problems will lead to passive production , In serious cases, the production process will be interrupted , Production parking , The plan is difficult to complete . Production scheduling is to understand and master these in time . Organize relevant personnel to deal with and solve these problems , remove a hidden danger , Ensure the safe operation of production and the realization of production plan and production operation .

2. Coordinate the relationship 、 Implement the instructions of the leaders

Enterprise production moves towards depth 、 Joint processing , Leadership and management are multi-level and wide range . therefore , Coordinate the relationship between top, bottom, left and right , It plays an important role in ensuring the normal operation of the production process . Coordination ability is the embodiment of further exertion of dispatching function .

3. Collect production trends and relevant data

Production scheduling should not only organize and realize the production plan , And in the process of organizing production , There are many crafts 、 equipment 、 Environmental protection 、 Security 、 quality 、 supply 、 sales 、 The dynamic situation of services and many original data , Need timely 、 Record accurately , This is an important basic work .

Record these data and situations timely and accurately , We can provide timely services to leaders at all levels 、 All departments know about production 、 Provide real and reliable basis for commanding production , It can be saved as useful data .

Production scheduling is to organize and implement the production schedule . Production scheduling is based on the production schedule , The production schedule shall be realized through production scheduling . The necessity of production scheduling is determined by the nature of production activities of industrial enterprises .

Modern industrial enterprises , There are many production links , Collaboration is complex , Strong production continuity , Things are changing fast , Failure of a part , Or a certain measure is not realized on schedule , The whole production system is often affected .

therefore , Strengthen production scheduling , For timely understanding 、 Master the production progress , Study and analyze various factors affecting production , Take corresponding countermeasures according to different situations , It is very important to narrow the gap or return to normal .
