Case Study - Trailer Manufacturing
Streamline your entire process from Quoting through Production Schedule Management!
Background
The company in this case study manufactures and sells build-to-order trailers to dealers and customers. Just like in the automotive business, dealers buy in two ways: 1) inventory with options they think will sell (stock on the ground), 2) customized to customer requirements (order and wait).
Because each trailer is unique, there is no part number at the time of quoting. Because there is part number for the trailer, determining the cost and price is more complex than adding line items to a quote. The cost is function of: 1) the parts that go into the vehicle (the BOM), 2) the process time required to assemble (production router).
Because of this complexity, preparing a quote is a complex process. Whether an ERP software or Excel is used, preparing the quoteis not as fast as customers expect these days - the customer must wait for a price.
Problem
The company has recognized that the significant manual effort in scheduling requires they do something different in how they run the business. One solution explored is an ERP software.
ERP software is designed to have an assembly (top level) part number for every line item (on a quote or sales order and production order). Below this assembly part number is a unique production router and bill of materials. Using an ERP for a configured product to create a quote with 5 line items would require creation of: 5 assembly part numbers, 5 production routers and 5 bills of material (BOM). This is made somewhat easier by duplicating and then editing an existing router and BOM. The router still requires the manual esimation of the process time per step - which is a function of the product complexity. This manual work is required for every single quote - whether the business is won or lost!.
BOM
The Bill of Materials is clearly quite extensive and is defined as:
- Base materials/items. Items that are common across all trailers regardless of options selected. This is model specific
- Subassemblies for each option selected
Router
The base trailer has a defined set of processes required such as:- WELD - Welding
- PAINT = Painting
- CHASS - Chassis
- BODY - Body
- ELECT - Electrical
- FITOUT - Fit out (Kitchen, etc
- WHEELS - Wheels
- FINISH - Finish
- FINAL - Final Test

- Item Mapping (Product Specific)
1) Attributes
The attributes that the user would select are shown here. These are setup in Velosity.

2) Items
The items that are added by the Rules or Item Mapping are shown here.

4) Rules
The rules that are evaluated to generate the router and BOM are shown here.

Results
With this setup, the customer is able to generate quotes and orders within a few minutes (without creating any routers or BOM!), like this:
