Use this tool to analyze the current demand and supply situation based on production order BOM information in your current ROB-EX Scheduler plan.
This tool can provide additional insight in your multi-level BOM production.
To startup this tool, right click an operation in the Gantt chart belonging to an order which either produces or consumes a semi-finished or finished product. Then select the option “Materials->Analyze dependencies->Forward/Backward”.
The full BOM analysis is carried out and the result is shown in a tree-type table, allowing you to drill down into different demand/supply paths, that can be taken. Each row in the analysis result is a supply/demand pair. I.e. a production order supplying and a production order consuming a certain material.
Click the top right settings button, to change analysis parameters.
- The type of material to analyze for demand/supply relation ship
- Days forward/backward are the number of days to search within, from respectively the supply or demand date in question. Make this number smaller to limit possible solutions. A number of 2 forward days, means that on a forward search, the demand must be found from within a 2 day window of the supply.
Several different columns provide information about a given row. Let’s explain some of these columns:
Supplied by: The production order no. of the supplying order
Used in: The production order no. of the consuming order
Slack: the number of days between when the supplying operation ends and when the demanding operation starts.
Slack sum: the lowest slack sum from the current tree level, recursing down into its children. If the sum is negative you know it is not a viable solution, unless some of the involved orders are rescheduled.
Inventory including demand: The net inventory level of the specified material, after the amount demanded has been deducted. If this is negative, you know this may not be a viable supply chain, as the demand, with the current schedule, is not being met.
