The APICS-Standard Planning Framework
Intro to Supply Chain Materials Any commodities used directly or indirectly in producing a product or service. Raw materials, component parts, assemblies, finished goods, and supplies Supply chain Flow of materials through various organizations from the raw material supplier to the finished goods consumer.
Supply Chain Management Definition All management functions related to the flow of materials from the company’s direct suppliers to its direct customers. Functions included: purchasing, traffic, production control, inventory control, warehousing, and shipping. Two alternative names: Materials management Logistics management
Supply Chains Definition Supply Chain – A supply chain is the network of organizations, people, technology, activities, information and resources involved in the production of a product or a service – Includes suppliers, manufacturers, transporters, warehouses, retailers and customers Production System – A manufacturing subsystem that includes all functions required to design, produce, distribute, and service a manufactured product. A Supply Chain consists of one or many production systems that work together in the fulfillment of a customer order Best viewed as a network

Receiving and Inspection Raw Materials, Parts, and In-process WareHousing Production Finished Goods Warehousing Inspection, Packaging, And Shipping Materials Management Purchasing Production Control Physical materials flow Information flow Warehousing and Shipping Inventory Control and Traffic Customers Suppliers Supply Chain Management in a Manufacturing Plant
Logistics Logistics usually refers to management of: the movement of materials within the factory the shipment of incoming materials from suppliers the shipment of outgoing products to customers
Movement of Materials within Factories The typical locations from/to which material is moved: Incoming Vehicles Receiving Dock Quality Control Warehouse Work Center Other Work Centers Packaging Finished Goods Shipping Shipping Dock Outgoing Vehicles
Shipments To and From Factories Distribution Resource Planning Distribution resource planning extends DRP so that the key resources of warehouse space, workers, cash, and vehicles are provided in the correct quantities at the correct times.
Analyzing Shipping Decisions The “Transportation Problem” Problem involves shipping a product from several sources (ex. factories) with limited supply to several destinations (ex. warehouses) with demand to be satisfied Per-unit cost of shipping from each source to each destination is specified Optimal solution minimizes total shipping cost and specifies the quantity of product to be shipped from each source to each destination
Warehousing Definition Warehousing is the management of materials while they are in storage. Viewed as distribution center (DC) Warehousing Accounting Ordering Storing Dispersing activities:
Warehousing Record keeping within warehousing requires a stock record for each item that is carried in inventories. The individual item is called a stock-keeping unit (SKU). Stock records are running accounts that show: On-hand balance Receipts and expected receipts Disbursements, promises, and allocations

Characteristics of the SC Network Each node may consist of a production system of its own Links in the network represent a business relationship between two nodes e.g. transportation of a product between two nodes The number of levels in a supply chain varies and depends on the complexity of the product Flows can skip levels by that: Supplier ships direct to DC Manufacturer ships directly to customer The decoupling point is the shift occurs from make-to-stock to make-to-order The decoupling point is not fixed to one level of the supply chain and is influenced by postponement strategies (e.g. Dell)
Characteristics of the SC Network Multiple Products, each with possibly different Bills of Material and multiple configurations Multiple Suppliers for raw materials, parts or subassemblies Multiple Subcontractors Multiple Plants possibly containing a wide variety of equipments Multiple Warehouses – Distribution centers, local, regional and factory warehouses Different means of Transportation (air, sea, rail, FTL, LTL) either leased, owned or contracted Different information systems and communication channels People with various skills at all levels of the organization
Example of Costs and Revenues in the Supply Chain Costs – Production and purchasing costs – Setup or changeover costs – Transportation and handling costs – Hiring and firing costs – Overtime costs – Inventory costs – Promotional and advertising costs – Renting and leasing costs – Subcontracting costs – Overhead – Capital investments and depreciation – Taxes and duties Revenue – Customer is the only source of revenue From sale of products, spare parts, materials or service
Example of Constraints Productivity constraints Equipment capacity constraints Labour availability Technological constraints Inventory constraints Purchasing, manufacturing and distribution lead times Demand uncertainties and seasonalities Service requirements Budget Regulations and other constraints
Categories and Attributes of a Supply Chain - Reproduced from Fleischmann B., Meyr H, Hierarchy and Advanced Planning Systems, Handbooks in OR and MS, Chapter 9, Elsevier, 2003, pp 457-523
Types of Production Systems Pure Inventory Systems 1. – – – 2. – – Simplest form of logistic system Only procurement activities with no production or complex distribution processes Example: wholesale or retail operations where items are purchased Continuous production Systems Manufacturing of a few families of technologically related products in large quantities Example: Assembly lines or fabrication lines Intermittent production Systems 3. – 4. – Batch production of many products which share several processing centers Project based systems Production of a unique complex product such as a ship or a bridge
Production Strategies Make to Stock Production is based on forecasted amounts for stocked items Make to Order Production of a product is made for a customer order in the quantity specified by the order
2. Hierarchical Planning Hierarchical planning was first introduced by Robert Anthony in 1965* as a three level management framework that consists of: – Strategic or long-term planning – Tactical planning (or management control) for mid-term planning – Operational planning for short term planning The results of one each level are considered as an inputs to the lower level planning Effective implementation and control of the plans requires: – An execution layer that captures the events as they occur – Feedback loops at all levels * R.N. Anthony, Planning and Control Systems: A Framework for Analysis, Cambridge. Mass., 1965
Hierarchical Planning Framework Long term Mid term Short term -Material programs - Supplier selection - Cooperation - Plant location - Production systems - Subcontractors - Physical distribution structure - Transportation strategy -- Personnel training -- Contracts -- Material Requirements Planning -- Master production Scheduling -- Capacity planning -- Distribution planning -- Personnel scheduling -- Material ordering -- lot-sizing - operations scheduling - shop floor control -- Mid-term sales planning - Warehouse replenishment - Transportation planning -- Mid-term sales planning EXECUTION Flow of goods - Product program - Strategic sales planning Information Feedback
Differentiating Factors by Planning Levels Factor- Level Strategic Tactical Operational Purpose Supply chain design, resource acquisition Planning resource utilization Operation scheduling and execution Implementation instruments Policies, objectives, capital investment Budgets Schedules, procedures and reports Planning horizon Long: 3-5 years Medium: 6-18 months Short: daily, weekly, monthly Scope Broad corporate level Medium plant level Short floor level Level of Management Top Middle Low Frequency of re-planning Low: every few years Medium: monthly or quarterly High: weekly, daily or as required Source of information Largely external External and internal Largely internal Level of aggregation - product data - time High Product families years Medium Product groups Month Low individual products continuous Degree of uncertainty High Medium Low Degree of risk High Medium Low
