12、lanningSCM Processes OverviewThe following figure briefly describes the solution architecture for the core processes that constitute the SCM solution. SCM ProcessesThe SCM template as a whole performs the following functions:1. Demand Planning: Forecasting and demand collaboration. Sales forecasts a
13、re generated using various statistical models and customer collaboration.2. Master Planning: Long term and medium term master planning for material as well as capacity. Master planning can be done at both the enterprise level (for critical shared components) and the factory level. In addition, decis
14、ions relating to material procurement and capacity outsourcingof materials from suppliers (or capacity outsourcing decisions) can be made.3. Allocation Planning: Reserving product supply for channel partners or customers based on pre-specified rules. Also, managing the supply so that orders that hav
15、e already been promised can be fulfilled in the best possible manner (on the promised dates and in the promised quantities).4. Order Promising: Promising a date and quantity to customer orders. These promises are made looking at the projected supply. In addition, sourcing decisions are also made her
16、e after considering such variables as lead-time, product cost, shipping cost, etc.5. Order Planning: Detailed order planning encompassing multiple factories. In addition detailed transportation planning is also done which can handle such complex requirements as merging two shipments from different l
17、ocations during transit.Information flows seamlessly between all these functions. The inputs to the system are the static data (supply chain structure, supplier relationships, seller and product hierarchies, supplier relationships, etc), some forecast data and actual orders. The output is a comprehe
18、nsive and intelligent supply chain plan which takes all the supply chain delivery processes into consideration in order to maximize customer satisfaction, at the same time reducing order fulfillment lead times and costs.The scope of this document is to describe the scenarios modeled as a part of the
19、 current release of the template (Hitech2). For any planning system, the place to begin planning is demand forecasting. We look at this in more detail in the next section.Demand PlanningThe objective of the Demand Planning process is to develop an accurate, reliable view of market demand, which is c
20、alled the demand plan. The Demand Planning process understands how products are organized and how they are sold. These structures are the foundation of the process and determine how forecast aggregation and disaggregation is conducted. A baseline statistical forecast is generated as a starting point
21、. It is improved with information directly from large customers and channel partners through collaboration. The forecast is refined with the planned event schedule, so the demand plan is synchronized with internal and external activities. Each product is evaluated based on its lifecycle, and continu
22、ally monitored to detect deviation. New product introductions are coordinated with older products, pipeline inventories, and component supply to maximize their effectiveness. Attach rates are used to determine component forecasts given the proliferation of products. The result is a demand plan that
23、significantly reduces forecast error and calculates demand variability, both of which are used to determine the size of the response buffers. The specific response buffers and their placement are different based on the manufacturing model employed, therefore the Demand Planning process must represen
24、t those differences.Order PlanningDemand PlanningOrder PromisingAllocationPlanningDemand ForecastingTop down forecastingBottom up forecastingLife cycle planningOption forecast Consensus forecastingForecast extractionDemand CollaborationDemandPlanningCustomersOrder Creation& CaptureForecast NettingMa
25、ster PlanningThe following figure identifies the key processes that constitute demand planning and the scenarios that are modeled in the template.Demand ForecastingTop-Down ForecastingDefinitionTop down forecasting is the process of taking an aggregate enterprise revenue target and converting this r
26、evenue target into a revenue forecast by sales unit/product line. This allocation process of revenue targets can be done using historical performance measures or using rule based allocation techniques. The revenue targets can further be broken down into unit volume forecasts by using Average Selling
27、 Price information for product lines.Historical information is typically more accurate at aggregate levels of customer/product hierarchies. Therefore, statistical forecasting techniques are typically applied at these aggregate levels. At levels where historical information might not be very relevant
28、 or is not perceived to be accurate, this allocation can be done with a rule-based approach. Frequency: This process is typically performed at a monthly/quarterly frequency, with the forecast being generated for the next several months/quarters. Scenario DescriptionBased upon historical bookings at
29、an aggregate level across the entire company (for all products and geographys), the system will automatically generate multiple forecasts using different statistical techniques. The statistical techniques will account for such things as seasonality, trends, and quarterly spikes. Each statistical for
30、ecast will be compared with actuals to calculate a standard error. This will automatically occur at every branch (intersection) in the product and geographic hierarchies. The aggregate statistical forecast generated for the entire company will be automatically disaggregated at every intersection usi
31、ng the statistical technique with the smallest standard error. The outcome of this process will be a “Pickbest” statistically generated forecast at every level in the product and geography hierarchies. This forecast is then used as a baseline or starting point.Inputs Historical Bookings by units His

34、This process consolidates the knowledge of sales representatives, local markets, and operational constraints into the forecasting process. This forecast can be aggregated from bottom up and compared to the targets established by the top-down forecasting process at the enterprise level. This will ena
35、ble easy comparison between sales forecasts and financial targets. Frequency: This is a weekly process. However, there is continuous refinement of the forecast at an interval determined by the forecasting cycle time and/or nature of the change required.Scenario DescriptionIn parallel with the top-do
36、wn forecast, the sales force/operational planners will enter forecasts for independent demand for a particular SKU or product series by customer or region as is pertinent to a particular Product / Geography combination. This data will automatically be aggregated and compared to the targets establish
37、ed by the top-down forecasting process. Using the Average Selling Price for a unit, the unit based forecasts can be converted to revenue dollars and automatically aggregated.The bottom-up forecast can also be generated using collaborative demand planning with a customer. In this case, the consensus
38、forecast for a product/product series for a customer is aggregated and compared to the top-down target.

40、Cycle Planning New Product Introductions and Phase-In/Phase-OutDefinition Forecasting product transitions plays a critical role in the successful phasing out and launch of new products. New Product Introduction (NPI) and phase In/phase out forecasting allows the enterprise to forecast ramp downs and
41、 ramp ups more accurately. Ramping can be defined in terms of either a percentage or as units. Typically new products are difficult to forecast because no historical information for that product exists. NPI planning must allow for new product to inherit historical information from other product when
42、 it is expected that a new product will behave like the older product. In situations where a new product will not behave like any other older product, NPI planning allows a user to predict a life cycle curve for a product, and then overlay lifetime volume forecasts across that curve.Scenario Descrip
43、tion Given a forecast for two complimentary products, the user can change the ramping percentage of both to reflect the ramping up of one product and the ramping down of another. Given a New Product Introduction that is predicted to behave like an older product, the user can utilize historical data
44、from the older product to be used in predicting the forecast for the new product. The scenarios for this process are executed in TradeMatrix Demand Planner. Future releases of the template will use TradeMatrix Transitional Planner to do product life cycle planning.Inputso Historical bookingso New pr

A promotional campaign or price change by the company or the competition is an example of an event related factor that may influence demand. The marketing forecast is adjusted up or down by a certain f
48、actor. The factor can be increased or decreased across periods to simulate a ramp-up or a ramp-down in sales depending upon the nature of the event.
