Supply planning is one of the four supply chain planning processes: supply, demand, production, and fulfillment Note in the figure how these processes overlap the three supply chain functions: procurement, manufacturing, and fulfillment (Click the boxed-in arrows for more details.) In a well-run supply chain, the planning processes are interdependent Plans from one process depend on and feed the other plans The goal is to synchronize the plans—and the planners—by integrating the processes This helps you answer key questions: ● ● How the planning processes relate to each other? What should I with the information from my or another planning process? Let's look at each of these questions before we get into the details of supply planning Course Objectives After completing this module, you should be able to the following: ● Identify the purpose, objectives, and benefits of supply planning file:///Z|/staemodules/moved_vault/emod230/course/transcript.htm (1 of 32)5/18/2007 3:42:36 AM Transcript ● ● ● Describe the different components of supply planning, the business problems they solve, and the key capabilities they require Identify key inputs, outputs, and concepts for each of the components of supply planning Describe the metrics used to measure the effectiveness of supply planning Introduction to Supply Planning Overview A supply chain is a network of the entities—within and across companies—involved in producing, shipping, and distributing products Each entity is a link in the movement of a product from its raw materials stage to its consumption by the customer A typical supply chain has the following entities: ● ● ● ● Inventory Plan – Determine and plan for how much inventory to hold (finished goods) and where to place the inventory (in which distribution centers) Distribution Plan – Determine how, when, and where to replenish this inventory Sourcing Plan – Plan when and where to manufacture a product Materials Plan – Determine what materials are needed and when Supply Planning Constraints Every company is restricted in some ways in its ability to produce and deliver goods This concept called "constraints" is central to the supply planning process For something to qualify as a constraint, it must be definable in terms of a resource—for example, transportation, manufacturing, labor—and a given time period With money and resources, a constraint is addressed and is no longer an issue Capacity Constraints Refers to the number of products that can be produced over a period of time For instance, a manufacturing line can produce only a certain number of motorcycles in a week Materials Constraints Occurs when the number of red motorcycles produced in a week, for example, is limited by the number of red fenders available from a supplier (This is not just a materials constraint for the manufacturer, but also a capacity constraint for the fender supplier.) Transportation Constraints Occurs when transportation capacity is limited for a given time period; when the preferred mode (truck, rail, air) is not available or usable; or when customer requirements (for service or a preferred mode) cannot be met Lead-Time Constraints Reflects the time it takes for material to progress from one stage to another For example, "manufacturing lead time" refers to the time it takes for product to be manufactured "Transportation file:///Z|/staemodules/moved_vault/emod230/course/transcript.htm (2 of 32)5/18/2007 3:42:36 AM Transcript lead time" is the time it takes for product to move from one location to another Components of Supply Planning Supply planning has three components—Inventory Planning, Distribution Planning, and Master Production Scheduling (MPS) How much…where…and when (see the figure) SUPPLY PLANNING Inventory Planning Plan how much inventory to maintain to meet customer demand Distribution Planning Plan where to manufacture the product to meet actual customer demand Plan how to distribute the product to distribution centers and customers Master Production Scheduling Plan when to manufacture the product to meet actual customer demand Plan material requirements to meet production schedule Supply ...ANALYSIS OF THE SUPPLY CHAIN DESIGN AND PLANNING ISSUES: MODELS AND ALGORITHMS HUANG YIKAI (B.E. and M.

What quantities of raw materials should we order so we can meet that level of production, and when should they be ordered? • A successful company must be able to: • Develop a good production plan • Execute the plan • Make adjustments when customer demand differs from the forecast Concepts in Enterprise Resource Planning, Second Edition Production Overview • Three general production approaches: • Make-to-stock: products are made for inventory in anticipation of sales orders • • Make-to-order: products are made to fill specific customer orders • • Most consumer products are make-to-stock Expensive products or products made to customer specifications Assemble-to-order: combination of make-to-stock and maketo-order • Final product assembled for a specific customer order from stock components Concepts in Enterprise Resource Planning, Second Edition Fitter Snacker’s Manufacturing Process • Snack bar line produces: • 200 bars/minute • 3,000 lb/hr • Production line operates for one 8-hour shift per day • Raw materials are mixed in one of four mixers • Mixers can produce 4,000 lb of dough per hour • Excess capacity protects snack bar line from shutting down if a mixer breaks • The oz snacks are packed 24 to a display box with 12 display boxes packed to a case • Changing from NRG-A to NRG-B bars takes 30 minutes Concepts in Enterprise Resource Planning, Second Edition Mixer Snack Bar Line Form Bake Mixer Mixer Pack Finished Goods Warehouse Raw Material Warehouse Mixer Figure 4.1 Fitter Snacker’s manufacturing process Concepts in Enterprise Resource Planning, Second Edition Fitter Snacker’s Production Problems • Fitter Snacker’s production problem is deciding how many snack bars to make and when to make them • Fitter Snacker’s main production problems are in the areas of: • Communication problems • Inventory problems • Accounting and purchasing problems • All of which are exacerbated by Fitter Snacker’s un-integrated information system Concepts in Enterprise Resource Planning, Second Edition Communication Problems • Communication problems exist in most companies • Magnified in a company without an integrated information system • At Fitter Snacker, Marketing and Production not communicate or coordinate planning • Production is not always informed of sales promotions or unexpected planned orders • Can result in depleted inventory, overtime production, expedited shipments and material shortages • Production may not inform Marketing about planned maintenance, which will reduce production Concepts in Enterprise Resource Planning, Second Edition Inventory Problems • Production manager schedules production based on experience, rather than formal planning techniques • Primarily compares current warehouse inventory Supply Chain Planning: Production Planning Introduction Why is Production Planning Important? The goal of production planning is to support the manufacturing process by determining the resources and sequence of operations required to build a product During the production planning process, a company generates the detailed production schedule required to build a product The production schedule must be tightly linked with a detailed materials plan to ensure the raw materials are available when needed The planning process also communicates required materials to the purchasing department The primary business issues addressed by production planning include: • • Ensuring machines and materials are available for production when needed Maximizing throughput and utilization of factory resources Copyright (c) 2004 Accenture All rights reserved You may only use and print one copy of this document for private study in connection with your personal, non-commercial use of a Supply Chain Academy course validly licensed from Accenture This document, may not be photocopied, distributed, or otherwise duplicated, repackaged or modified in any way Note: interactive elements such as activities, quizzes and assessment tests are not available in printed form How is a Production Planning Integrated with Supply Chain Planning? Production planning is one component of the supply chain planning process Supply chain planning is an integrated process that allows companies to plan and integrate the supply chain functions of procurement, manufacturing, and fulfillment Demand, supply, production, and fulfillment planning operate as interdependent supply chain planning functions The goal is to integrate these processes so that all the plans are synchronized with one another Plans generated during one process are used by one or more of the other processes In other words, planners need to know: • • What to with the information generated How the different processes relate to one another Specifically, a materials planner may wonder, "What if my suppliers can't deliver to our requested quantities and timing?" There are many ways to resolve this issue One viable option is to delay the production of some of the items until materials are available, and inform fulfillment planning about the delay in meeting customer requirements Another option may be to work with Procurement to determine if the finished goods could be sourced from another vendor Copyright (c) 2004 Accenture All rights reserved You may
