Question
week 1

Master Planning (graded) How does master planning affect the overall organization? Why is this a necessary part of the overall management process of an organization? Planning Horizons (graded) What are time horizons as used in the corporate planning process? How do these horizons affect our forecasting processes?

let’s first considertime horizons as used in the corporate planning process. What are these horizons and how do they affect our forecasting processes? week 2

Which forecast error measuring tool is the best? (graded) Of the four error tracking tools we have learned about in our assigned textbook reading (MAD, MSE, MAPE and seasonality), which method provides the best way to track forecast error? Give examples.

Is it possible to forecast seasonal products without removing the seasonal variations? (graded) We calculate a seasonal index in order to remove the seasonal component before creating a forecast. Is it possible to remove this step and create a forecast with the seasonal variation still in place? Why or why not? Explain.

whether it is possible to just leave the seasonal variation that may exist in our historical data in place when developing a forecast? What are advantages and disadvantages of doing this?

week 3

Aggregate Planning Strategy (graded) Mixing options to develop an aggregate plan is a common practice. How would you mix the chase and level strategies at your place of employment (or former place) to come up with a better overall plan?

Aggregate Planning in Services (graded) How do plans differ in services from a production or manufacturing setting? How do the planning strategies impact operational plans in services? week 4

Inventory Management (graded)

What is inventory management? Is inventory management really any more than just counting what is available in the warehouse and reporting that to operations? It's a matter of buying more when you are short, and holding what you have for an emergency, right? Inventory Models (graded) Choose one of the inventory models (either from the independent demand section or the dependent demand section), and explain why that model works in certain situations and not in others. Do we really need this many different ways to count widgets? How do costs come into play in such planning decisions?

weeek 5

Master Scheduling Time Fences (graded) What are time fences? Why are they used?

To get started, let's consider our lead question in this Week 5 thread: Are master schedule time fences important in maintaining a stable master schedule? Why or why not? What are your thoughts?

Overloaded Master Schedule (graded) Capacity planning is used to ensure that the MPS is not overloaded. Discuss the effects that an overloaded MPS has on the MRP system and the factory.

let's discuss the fact that capacity planning must be used to ensure that the MPS is not overloaded. Discuss the effects that an overloaded MPS has on the MRP system and the factory.

Note that the traditional MRP algorithm assumes infinite capacity. It is up to the organization that runs an MRP program as a part of the ERP system that it purchased to buy a Capacity Planning module for that ERP system or conduct its own capacity planning using Excel. When I worked at Hamilton Sundstrand and we ran MRP every weekend in our JD Edwards ERP system, we did not purchase JDE's Capacity Planning module. So we had to do capacity planning outside of the ERP system in Excel. week 6

Material Requirements Planning (MRP) (graded) What exactly is material requirements planning (MRP)? Why is MRP referred to as a dependent demand scheduling system?

Let's try to make sure everyone understands, by the time we are through with this discussion, where the following fit into the MRP picture and whether each is an input or an output or neither: BOM, Inventory Status, PO Suggestions, WO suggestions, MPS, Capacity, Sales Orders, Forecasted Sales Orders, Supplier Lead Time, WIP, Finished Goods Inventory.

DRP and ERP (graded) How do distribution resource planning (DRP) and enterprise resource planning (ERP) differ? Why do we need all of these complicated systems? Can't we just make our products and sell them for a profit? How does using systems like ERP and DRP improve our operational efficiency?

Class,

Let's bring our experiences into this discussion so we can learn from the experiences of one another in addition to learning from the information presented in the textbook! Have you worked with an ERP system? Given that we are discussing MRP in the other thread this week, how do MRP and ERP relate to one another? Do they?

week 7

Why Lean? (graded) Lean production is a way to eliminate waste through a focus on what the customer wants. First, can we ever really know what the customer wants? And second, even if we can determine what the customer wants, how can that help us reduce waste?

Just-In-Time (graded) How does JIT practice differ when applying it to services compared to when we use the concept in manufacturing? What advantage, if any, do we get from using JIT in the service sector? week 1
