Procedure of Production Planning

1. Production Material: The  information is  derived  from an analysis  for the production  into its  separate components  and units  to determine  the kind  grade or quality and quantity of each required.

2. Availability  of Materials: The balance on  hand  of stock items  are determined  from the stores  keeping  records,  and the  time  required  for delivery where  not stocked is determined  from  the purchasing  records.

3. Standard of Quality for Each Unit: The information is derived from engineering drawings and specifications, or from practical experience in the class of work, and is expressed as limits and tolerances in machine work.

4. Machine  Output or Equipment Capacity: This  information is  derived from an analysis of machine  capacity and consists of the units of work per hour capable  of being handled by each machines or process.

5. Operations Methods: This information is derived from technical experience,  but is  based  on the analysis of  machine  capacity. The  product  units  are grouped  into subassemblies  and the most  economically sound  procedure for performing each  operations on  each  unit  is determined. In  machine shops this  includes the  determination of the amount  and kind of auxiliary equipment,  tools jigs  and fixtures necessary  for efficient  production .

6. Sequence of  Operations: The  information is derived from  technical  experience aided by an accurate knowledge of  machine  layout and form  records  of previous  work. It consist of a detonation of the order in which operations shall be performed on each production item.

7. Operations Time Allowance for  Each  Operations  on Each units: This  information  is derived of machine analysis, and  from technical experience. In scheduling this time is increased by an allowance factor that takes care of normal machine  down time   and temporary storage between operations.

8. Assignment of Due Dates: A data is assigned for commencement and completion of each operation on each  unit  of product, and for finial assembly or completion of the  order. When assigned these dates from the time basis of the outer sheets and the production schedule.
