You can use assembly bills of material to create job material requirements. You can also use routings to schedule job production activities and create operation specific material and resource requirements.
In discrete manufacturing, production costs are normally charged to a job. This is called job costing. You open jobs, collect charges, close jobs, and analyze and report costs and variances by job.
If Oracle Projects is installed and the Project References Enabled and Project Control Level parameters are set in the Organization Parameters window in Oracle Inventory, you can assign project and, if required, task references to planned orders, jobs, purchase orders, sales orders, miscellaneous transaction and other entities within Oracle Manufacturing.
If the Project Cost Collection Enabled parameter is also set, you can optionally collect and transfer manufacturing cost to Oracle Projects. Project costs are tracked by project/task and expenditure type.
You define repetitive schedules by the assembly, its daily quantity and its production lines, no job or work order exists. You can schedule production of a single assembly continuously for just a few hours or for any number of days.
You can schedule repetitive production based on the fixed lead time of your production line if the lead time does not vary from one assembly to another assembly. If the lead time varies by assembly, you can schedule the repetitive production time based on the routing of the assembly the line is building.
In repetitive manufacturing, you charge the cost of production directly to the assembly and line. You analyze and report costs by assembly and line during the period close. At period close, all charges to a repetitive assembly for that period are totalled and divided by the number of assemblies produced during that period. Period close also calculates assembly costs and usage variances.
Repetitive schedules and discrete jobs can coexist. Oracle Master Scheduling/MRP and Oracle Supply Chain Planning plans production using repetitive or discrete planning techniques based on the planning type you specify for the item in Oracle Inventory.
To prepare for flow manufacturing, you design production lines and production processes so that each line can produce a constantly changing mix of products within a family at a steady rate. Flow manufacturing production lines are designed to support the inter-mixed production of multiple products within a family on the same line. Line design includes grouping products into families, defining the processes and events required to produce each product, and grouping events into operations. By specifying demand rates for each product you can predict line capacities. As a part of line design, you can specify demand forecasts for the products, derive TAKT times (also called Operational Cycle Time), and calculate optimal kanban quantities.
Flow manufacturing can be used in Oracle Inventory to replenish kanbans and in Oracle Work in Process to complete assemblies without having to created a job or a schedule. See: Performing Work Order-less Completions.
