What is advanced planning and scheduling-APS?

Some are called advanced planning systems, while others are advanced planning and scheduling ). Definition is not the most important. The most important thing is that all resources are synchronized, real-time, constrained, and simulated, regardless of materials, equipment, personnel, supply, and customer needs, transport and other influencing planning factors. Long-term or short-term plans are optimized, compared, and executable. It will adopt a memory-based computing structure ,. This kind of computing processing can be performed continuously. This completely changed the batch processing computing mode. All supply chain constraints can be considered concurrently. When each change occurs, APS checks capacity constraints, raw material constraints, demand constraints, transport constraints, and capital constraints at the same time, which ensures that the supply chain plan is effective at any time. Genetics will also be usedAlgorithmTechnology. It is a search technology and its goal is to find the best solution. This search technology is an Optimized Combination Based on imitating the biological evolution process. The basic idea of genetic algorithms is that evolution is to select the optimal type. Genetic algorithms will be applied to APs to obtain "Optimal" solutions. Currently, the APS system combines the multi-layer proxy technology and the intra-manufacturing APS Based on simulation to solve the manufacturing synchronization problem, simulate the APS optimization sequencer to solve the order conflict problem in the factory. In this way, the preparation and sequence of APS plans can be provided to manufacturers to address global priority and local optimization order of the factory, to meet the growing demand of the manufacturing industry for customers.

APSWhich of the following content should be included?

1.Job-based order priority plan
2. Event-based resource utilization maximization plan
3. Resource-based (TOC)-based bottleneck constraint plan
4. feasible plan based on material constraints
5. Future demand plans based on history
6. Distribution configuration plan based on supply Resource Optimization
7. Optimizing the transportation plan based on transportation resources

APSProvides Solutions for four types of manufacturing models in the manufacturing industry:

1 The stream program model and APs are mainly about sequential optimization. 2 , Discrete model, APS mainly solves the problem of multi-process and multi-resource optimization and scheduling. 3 , Mixed process and discrete model. APS simultaneously solves the problem of order and scheduling optimization. 4 The project management model and APS mainly solve the problem of minimizing the Key Path and cost time.

APS Consider solutions for different industries. The main focus of APS is the process logic constraints and resource capability constraints, and the materials and process processes are closely linked. various optimization rules. calculate the earliest possible start time and the latest possible start time. materials can be re-allocated and replaced, resources can be re-allocated and can be replaced. plan schedules consider flexibility (buffering), cost constraints, non-deterministic processes, and statistical probability theory. compare and analyze multiple optimization solutions.

APS Software generally consists of five main modules:Demand Planning, production planning and sorting, distribution planning, transportation planning, and enterprise or supply chain analysis.
