    • ERP & APS – An Overview
      • Enterprise Resource Planning (ERP) and Advanced Planning and Scheduling (APS) systems have improved the integration of materials and capacity planning by use of constraint-based planning and optimisation.
      • Many ERP and APS systems make it possible to include supplier and customer in the planning procedure and thereby optimise a whole supply chain on a real-time basis.
      • Instead of an ERP system that focuses on each individual link in the chain, an APS system acts like an umbrella, enabling to extract real-time information from that chain, to calculate a feasible schedule, resulting in a fast, reliable response to the customer.
    • What is APS?
      • APS is an enterprise and inter-enterprise planning system.
      • It utilises planning and scheduling techniques that consider a wide range of constraints to produce an optimised plan.
      • It optimises the plan, based on mathematical modeling techniques.
      • It determines a feasible plan that considers all demand needs and supply limitations.
      • It uses intelligent analytical tools to perform finite scheduling and produces a realistic plan.
    • What is APS? (Contd.)
      • It is an integrated system that can support shifting decisions in supply chain management.
      • It analyses the implications of alternative decisions, highlights problems & consequences, and schedules for transfer to execution tools.
      • It recommends a best overall solution that considers both material and resource availability.
      • Real time decision support & KPI support
      • Facilitate What If, ATP, CTP, PTP, Bucketless planning
    • Planning options, APS looks at..
      • Concurrent planning (or unconstrained planning)
      • Constrained planning
      • Optimisation - Linear Programming, Genetic Programming, Theory of constraints, Heuristics
    • 5M Constraints, APS looks at..
      • Material – availability, safety stock levels
      • Machine - set-up, sequence, capacity
      • Man - labour capacity, competence
      • Money – Cost
      • Methods - distribution requirements, customer service level requirements (due dates)
    • APS uses Finite Scheduling
      • Finite scheduling is a process that assumes a fixed maximum capacity.
      • It sequences jobs according to actual constraints (5M) the company faces.
      • It creates more realistic forecasts than infinite scheduling methods.
      • Improve the accuracy of the production process.
      • Performs multiple data passes to optimize plans and schedules.
    • Planning & Scheduling
    • What can APS do?
      • Compare supply chain performance to increase accuracy
      • Operate in real-time
      • Reduce inventories
      • Improve customer delivery times
      • Increase utilization of resources
      • Enhance efficiency of asset deployment
      • Resolve problems with ERP systems
      • Improves MRP processes
      • Employs more advanced technologies
    • How does APS system work?
      • Follow a four part model
      • Utilize company specific constraints
      • Employ advanced mathematical technologies
    • AMR’s – APS - Four Part Model ~ Created by Advanced Manufacturing Research, Inc.
    • Constraints Considered by APS
      • Limitations – eg. machine capacity, labor skills, and material requirements
      • Rules – eg. manufacturing policies enforced by the company that, have an impact on production
      • Objectives – eg. increase customer satisfaction, which could require that the company shorten lead times or improve delivery procedures
    • Mathematical utilised by APS
      • Linear programming
      • Genetic algorithms
      • Heuristics
      • Constraint based programming (CBP)
    • SCM Collaboration Demand Forecasting Optimizing product mix Capacity Planning Resource Planning Shop Floor Control Warehousing Management Ordering Administration Production Planning Demand Management Shipping Optimization Status Management Tactical Tactical Operational Operational Transcctional Transcctional Collaboration on Forecasting Collaboration on Capacity Planning Analyzing Supply Chain Collaboration on Resource Planning Inventory Tracking Inventory Planning Analyzing Supply Chain Shippment Tracking Order & Shipments Collaboration on Forecasting Matching demand -supply
    • APS Collaboration
    • Solution Provided by APS
      • Strategic and long-term planning
          • products to be made,
          • markets to pursue,
          • resolving conflicting goals,
          • ROI on asset deployment
      • Supply chain network design
          • Optimises the use of resources across the network of suppliers, customers, manufacturing locations and DCs.
          • What-if analyses can be performed to test the impact of decisions to open new or move existing facilities on profit and customer-service level.
          • To determine where a new facility should be located to fulfil customer demand in the most optimal way.
          • To find the balance between holding more stock at a specific location or making more transportation costs.
    • APS Solution (Contd)
      • Demand planning and forecasting
          • Both statistical and time-series used to calculate a forecast based on sales history.
          • Based on this forecast, you can create more demand through promotions in periods where the demand is less than maximum production.
      • Sales and operations planning
          • Use manufacturing planning and/or a supply chain network optimising solution to determine if the forecast demand can be met.
      • Inventory planning
          • Determines the optimal levels of safety stock at each locations of finished goods inventory to achieve the desired customer service levels.
      • Supply chain planning (SCP)
          • Compares the forecast with actual demand to develop a multi-plant constrained master schedule, based on aggregate-level resources and critical materials.
          • Optimise the use of manufacturing, distribution and transportation resources.
    • APS Solution (Contd)
      • Manufacturing Planning
          • Develops a constrained master schedule for a single plant based on material availability, plant capacity and other business objectives.
      • Distribution Planning
          • Based on actual transportation costs and material allocation requirements a feasible plan on the distribution of finished goods inventory to different stocking point or customers, is generated to meet forecast and actual demand including Vendor Managed Inventory.
      • Transportation Planning
          • Uses current freight rates to minimise shipping costs
          • Optimises outbound and inbound material flow to minimise transportation costs or to maximise the utilisation of the truck fleet.
          • Consolidates shipments into full truckloads and optimises transportation routes by sequencing the delivery / pickup locations.
    • APS Solution (Contd)
      • Production Scheduling
          • Based on detailed product attributes, work centre capabilities and material flow, a schedule is determined that optimises the sequence and routings of production orders on the shop floor.
      • Shipment Scheduling
          • Determines a feasible shipment schedule to meet customer due dates.
          • Determines the optimal method and time to ship the order taking customer due dates into account.
