How to understand the production scheduling of APS system?

APS System It is built on the basis of management decision specification and optimization calculation method , It is specifically used to deal with the scheme and production scheduling optimization problems or the corresponding solutions , It embodies a set of scheme and production scheduling information processing system in view of model base and specification base ; Its management decision-making norms are based on deliberative norms and constraint theory .

The optimization calculation method uses a variety of mathematical analysis algorithms , Such as linear programming problem 、 Integer mixed overall planning 、 logical reasoning 、 Constraint theory 、 Simulation, etc , Depending on the type of problem to be dealt with .

APS Production scheduling system Core functions

1、AP Plant advanced planning

Medium and long term net production demand . Consider customer orders 、 Sales forecast Forecast、 Delivery plan 、 stock 、 On the way 、 In system 、 Factory capacity 、 cost 、 Production lead time 、 Production cycle, etc , Inventory deduction 、 exhibition BOM, The net future production demand of each plant will eventually be generated , Planned order .

2、AS Workshop optimization scheduling

In the short term, the production line and machines of the workshop will be finely scheduled . According to limited capacity constraints , Give each production line in the workshop 、 Each machine , It should be from what time to what time , The production line of which production order should be made should schedule which operation at the minute level , How much , What kind of mold fixture , What material and how much .

3、 Accuracy of task completion time

Know how long it takes to complete the task , Although your design and cost engineer will know how long the task takes , But these times are only estimates in general . To ensure the best results , You need to collect actual data from the workshop by typically using the workshop data collection system .APS Software Provides the use of Gantt charts and other forms of visual scheduling , So that you can intuitively indicate when to complete various assignments 、 Mission .

4、WIP Real time view of

APS Production scheduling The system software can view in real time WIP And the best next step . If you are not sure about the progress of all aspects that have been carried out , How to determine the best action for the next step ？ Final , You will need information about the homework you have started , Completed jobs , Real time information about the suspended job and the reason . The integrated workshop data collection system will provide this level of intelligence in your factory workshop .

5、 Realistic capacity planning

APS Support integrated daily planning , Constraint based capacity planning , Hypothesis analysis , Limited plan, etc . In order to use tools to get an accurate production plan , It needs to understand any potential limitations in the plant . This includes labor , material , Shift mode , working hours , Covers an area of , Power limitation, etc - In fact, anything related to the constraint process .APS The environment must be able to capture and model all these constraints , Then use the model to generate a plan .

6、 share , The process of monitoring and updating

Use the generated plan , If not implemented , It won't benefit your facilities . Any schedule will change over time , In order to make any Schedule production The plan goes into effect , Must be shared with everyone involved in the execution . such , You will ensure complete visibility , And have the opportunity to solve any problems causing sliding .

APS How is it scheduled ？ How is the scheduling logic ？

Each final order to be scheduled has a commitment date , This date is committed through the order CTP（capable to promise） affirmatory . The logic of the scheduling algorithm operates on each order in the following way ：

（1） Automatically identify critical paths

（2） From the reverse of the commitment date , And retain the capacity and materials of the work center required by each process . If the required materials are already produced components , Then reverse plan it from its demand point . If at the end of this route , The start date is at or after the beginning of the scheduling time range , Then continue to execute the next order .

（3） If the reverse path fails , It means that the start date of the generation may have passed , Reserve capacity and materials from the planned start date . If the generated deadline is within the planned time range （ Although it may be after the commitment date ,） Then complete the plan for this order . If both the reverse and forward paths fail , The order will not be included in the planning period .

stay APS In the advanced scheduling system , The general production scheduling process is as follows ：

Basic data preparation （ Such as what products to make , Craft and BOM, Resources and equipment , Attendance sheet and production calendar ）→ Acquisition of dynamic data （ Supply and demand data ）→ Scheduling rules → Plan reached → Display of plans （ Like the Gantt Chart , Load diagram , Supply and demand balance sheet ）.

stay APS Production planning and scheduling Mixed market , Although many software companies claim to be able to do APS, But with independent original factory development APS There are really not many suppliers , Hui Du in China APS It's a good supplier .

APS The advanced scheduling system can handle the following problems

1、 A wide variety , Many varieties 、 The complexity of batch change ;

2、 The flow between processes generally adopts the parallel movement mode ;

3、 The standard process route is mixed with the characteristic process route ;

4、 Weighted multi-objective optimization , But it is also influenced by the preferences of decision makers ;

5、 With shifts （ Class three ） The consideration of , Can work overtime , You can also add an incomplete shift ;

6、 Processing tasks can be preempted , You can quickly switch , There is a constraint on switching time ;

7、 Optional equipment for each process , Optional mold for equipment 、 The cutting tool 、 Select tooling 、 Select material , Select a specific category of personnel ;

8、 On the premise of meeting the delivery date , process 、 equipment 、 work clothes 、 personnel 、 Optimal combination of uncertain factors such as materials ;

9、 The process may have processing time 、 Time to prepare 、 Waiting queue time 、 Mobile handling time and fixed offset time, etc .

Huidu APS The system can help enterprises strengthen production planning and execution management , Improve the level of enterprise operation and management , Create a replicable 、 Scalable production and operation management specifications , Achieve capacity balance 、 The beat is consistent , Efficient kneading and single row production , Balance production resources , Improve production and delivery capacity , Make the production plan more reasonable , More efficient , Optimize resource allocation , Realize the fine production of manufacturing industry .
