Overview
This page is based on the attempt to understand ADempiere Libero Manufacturing module of the author. It will be illustrated as a step by step guide for the reader to have the FEEL of what Libero Manufacturing can do and how to do it. Here I am referring to the Libero Manufacturing Work Shop conducted by Victor Perez some time back in 2009.
As such, this is by no mean the as the reference manual of Manufacturing Management in ADempiere and you can always find more reference from the original source in LIBERO
Briefing about Manufacturing Process
Libero Manufacturing Process is the mean of producing new Product based on specified Bill of Material (BOM & Formula), Manufacturing Resources, Workflows (how to produce) and Distribution (where to deliver).
- 1) First, we have to tell the system on how to produce products.
Product Planning Data is the master data that store the relationship between Product & BOM & Resource & Workflow, it also store the initial data about manufacturing process of each product, such as, Order Policy, Order Period, Batch Quantity, etc.
- 2) After the relationship of How to produce a product is defined we can start producing things.
Without planning, we can simply use Manufacturing Order manually. We then use the Component Check process to verify and use Print and Release Order process to print out checklist for user on the field. Once completed, store can use Order Receipt & Issue to accepted the newly created products into warehouse.
With Planning, we can use MRP. First the Forecast window will be used to store forecasting information (calculated outside ADempiere). Then we can run Generate Material Plan which will lookup Forecast data and based on it generate Manufacturing Order, Distribution Order, Purchase Requisition for the shortage products.
??? What is Calculate Low Level and Calculate Record MRP ???
Business Case 1: Chemical Industry (Process Production)
The Management of Garden World evaluated the possibility of getting a profits increase by manufacturing the fertilizer and took decision to open a new manufacturing plant to produce the fertilizer which before Garden World only purchased and sold.
So the engineering department designs two bills of materials to produce the Fertilizer in 50 and 70 kg packages and also a formula used for gross production of the fertilizer. The Lawn Fertilizer uses following raw materials:
- Phosphorus 17%
- Nitrogen 17%
- Potassium 17%
- Water 49%
Step 1: Define BOM
- &Menu > Manufacturing Management > Engineering Management > Bill of Materials & Formula
- Prepare BOM for Fertilizer_Lawn Fertilizer, which has the formula in % as above
- Prepare BOM for Fertilizer#50 and Fertilizer#70, of which components are Fertilizer and Bag
- See the summary of prepared BOM in BOM & Formula Info
Step 2: Define Manufacturing Workflow and Resources used in Production Process
- Define the Plant (Manufacturing Resource with Manufacturing Resource Type = Plant) that govern the production process
- Fertilizer Plant with Planning Horizon = 120
- Defines the Manufacturing Resources (Manufacturing Resource Type = Work Center) that will be used to produce any product in the Manufacturing Workflow
- Mixed Area
- Inspection Area
- Packing Production Line
- Define Manufacturing Workflow process to produce the fertilizer products
- Lawn Fertilizer
- Lawn Fertilizer Packing
- Define Workflow Activities and Resources
Step 3: Generate Demand for Manufacturing
There are different types of demand that can be generated, either internal, external, planning, ad-hoc, etc. In this guide the demand comes in 2 ways,
- Independence Demand (Sales Order)
- Dependence Demand (by Forecast and Planning)
Notes
Manufacturing Resources
- The Resource Type is used to calculate the available time in a Manufacturing Resource. It allows input of starting time and end time for the slot according to the working days.
- The Planning Horizon in Manufacturing resources is used for ???
Manufacturing Workflow
- If the workflow name is the same as the product name this Workflow will be the default Workflow for the product.
- The time constraint (i.e., Queuing Time, Waiting Time) in Manufacturing WF and Manufacturing Resource is different in that = ????
