What does Finite Capacity Scheduling and Unlimited Capacity Scheduling mean? What are the similariti

1.When there is.

When demanding, first assume that the ability can be easily changed, and then adjust the capacity to meet the actual appearance of the demand to the maximum extent, only when the ability can not be changed, then make the necessary adjustments to the demand, this matching method, in ERP, is called unlimited capacity scheduling.

2.When there is a demand, it is assumed that the ability is difficult to change, first see if the ability can meet these needs, if it cannot be met, then change the demand to match the current capacity, this matching method, in ERP, is called limited capacity scheduling.

1.When there is a demand, first assume that the capability can be easily changed, and then adjust the capability to meet the realization of the demand to the greatest extent, until the capability cannot be changed, then make the necessary adjustment to the demand, this matching method, in the enterprise resource planning (ERP), is called unlimited capacity scheduling.

2.When there is a demand, first assume that the capability is difficult to change, first see if the capability can meet these needs, if not, then change the demand to match the current capacity, this matching method, in the enterprise resource planning (ERP), called limited capacity scheduling.

The reason why you do the scheduling plan is to reduce the instability in the production process, but it does not mean that you can eliminate it, and the accuracy of your scheduling plan can be improved from 60% to 80 90%, which is actually progress, and does not mean that 100% is a good scheduling plan.

Reverse Scheduling, Reverse Scheduling is the scheduling type in Production Planning (PP), according to which the specific operation of the order is planned from the settlement date of the order. This schedule type is used to determine the planned start and end times of the order.

Reverse scheduling is a way of planning the network in the project system (PS), according to which the start and end times of the activities are calculated from the basic end time.

According to SAP scheduling, the batch size has a great impact on the processing time of the production order, and the actual logistics batch on site is collected first, so that the production order can be run in line with the actual cycle. For the problem of process time stacking, you can use CM21 to adjust the operation production time of a production order to balance the capacity load of the work center. This requires that the capability parameters in the work center are available for capacity planning items on the checkbox.

Production scheduling, also known as production planning and scheduling, is based on the limited production capacity, integrating the impact on production from the market, materials, production capacity, process flow, capital, management system, employee behavior and other parties, and obtaining a reasonable and effective production plan through the optimization of APS.

For some production types (e.g., job shop), production scheduling requires sequencing and scheduling of task orders on (potential) bottleneck resources; For other types of production, such as group technology, production scheduling should be able to automatically check the ability of the resource group to see if it can complete a set of orders for group processing in the next time period. This set of orders can then be manually sorted in order to be processed in the next time period.

Scheduling tasks can and should be done in a decentralized manner, so that the expertise of the people at each location and the knowledge of the current situation on the shop floor (e.g. personnel availability) can be leveraged.

Production planning is constrained by the upper-level master production plan, which establishes a framework for the execution of production planning in decentralized decision-making units. Appropriate guidance available from master planning includes: using the number of overtime or overtime; availability of material items from upstream facilities in the chain at different points in time; A purchase agreement that involves an input item from a merchant.

In addition, since the main production plan has a wider viewpoint and a longer planning interval in the ** chain, from which we can also get:

the seasonal inventory of each item that needs to be established at the end of the plan;

The order deadline for delivery to the downstream facility of the **chain (the downstream facility can be the next next production unit, distributor or end customer).

AOS Production Scheduling Optimization (AMO) provides unique production scheduling and optimization capabilities that enable companies to overcome this challenge with ease. By using the production planning and scheduling system software, the enterprise can formulate the overall optimal scheduling plan and realize the production management mode with the production plan as the command center within the enterprise. Advantages of AMO:

With the support of AOS Production Scheduling Optimization System (AMO), you can optimize on-time delivery, inventory levels, production efficiency and production costs as a whole, and enterprises can set appropriate weights for various optimization goals according to their actual conditions, and the system will automatically conduct data modeling and use complex operations research knowledge to find the overall optimal scheduling plan.

In addition, production management personnel can obtain various production abnormal warning information; The salesperson can reliably ** and promise the customer the delivery date of the order; Management can know the capacity load situation in real time; Procurement personnel can reasonably arrange material procurement according to the production plan; Merchandisers can easily know the progress of each production order from the system.

The AOS Production Scheduling Optimization System (AMO) can be easily integrated with traditional information systems, including ERP, MES and on-site control systems. This means you can continue to use your existing technology investments while gaining advanced, tactical production planning capabilities. Ios APS, production planning scheduling, Ios production scheduling system, production scheduling software.

Production scheduling is when the production capacity is far from meeting the order demand, and production management and sales together determine the production sequence and time of various models of automobiles.

The production scheduling system is a tool for short-term scheduling of production planning. Taking production scheduling as an example, it can not only take into account the production plan, including the number of orders, completion time, bill of materials, process flow, etc.;

As well as production line data, equipment status, personnel attendance and other capacity data, but also combined with the inventory quantity, purchase date, arrival date and other material demand results, even if the data in any link changes at any time, it can be adapted to make a correct production scheduling plan.

Production scheduling refers to the first plan of the workshop, according to customer orders, do a week, a month or even a quarter of production planning, scheduling is in accordance with the workshop gradually split the production process of parts.

The production scheduling system is a tool for short-term scheduling of production planning. Taking production scheduling as an example, it can not only take into account the production plan, including the number of orders, completion time, bill of materials, process flow, etc.;

This means waiting for the production schedule to be arranged.

That's right, that's what it means! Haven't you ever eaten pork, haven't you seen a run?

Production scheduling can be simply understood as the planning of production arrangement.

1. Modeling.

The shop floor model must capture the characteristics of the production process and the corresponding logistics in detail in order to generate a feasible plan at minimal cost.

Since the yield of a system is limited only by potential bottleneck resources, we only need to build a clear model of the total resources available on the shop floor, i.e. those that may become bottlenecks. We'll elaborate on the details of the modeling approach later.

2. Extract the required data.

Production planning and scheduling use data from ERP systems, master production planning, and demand planning. Production scheduling makes use of only a subset of the data available in these modules, so when building a model of a given production unit, it is important to indicate what data it actually needs, which can be recorded through the daily logging.

3. Generate a set of assumptions (production conditions).

In addition to the data received from data sources such as ERP systems, master production planning, and demand planning, decision-makers on the shop floor or production unit may have further knowledge or expectations about the current or future situation on the shop floor that are not available elsewhere (e.g. in software modules). In addition, there may be a variety of options for the available capacity of the workshop (e.g., flexible shift scheduling, etc.).

4. Generate an (initial) scheduling plan.

Once the model and data are in place, a schedule can be generated using a variety of sophisticated optimization methods such as linear programming, heuristics, and genetic algorithms for a given production situation. This can be done in a single step or through a two-level planning hierarchy (comprehensive production plan first, followed by detailed scheduling plan).

5. Analysis and interactive modification of scheduling plan.

If it is completed through a two-level planning level, it is also a production plan of the upper level of the integrated resource. Then, before generating a detailed schedule, one might first need to analyze the production plan. In particular, if production planning is not feasible, the decision-maker can interactively specify a number of planning paths to balance production capacity (e.g., additional shifts or specifying different machining paths).

This may be easier than modifying the machining operations on a single resource (lower-level scheduling).
