Production system: manufacturing support systems and facilities

Basic activities to convert raw material into finished products:

• Basic activities to convert raw material into finished products:
• i. Processing and assembly operations
• ii. Material handling
• iii. Inspection and test
• iv. Coordination and control

Processing operation transform a work material from one state of completion to a more advanced state that is closer to the final desired part/product. materials is fed into the process, energy is apply by the machinery and tooling to transform the material into finished products.

• Processing operation transform a work material from one state of completion to a more advanced state that is closer to the final desired part/product. materials is fed into the process, energy is apply by the machinery and tooling to transform the material into finished products.
• Assembly operations – two or more components combined to form a new entity
• Eg: Welding, Soldering, Screws, Rivets etc.

Moving and storing materials between processing and/or assembly operations.

• Moving and storing materials between processing and/or assembly operations.
• Inspection and test
• Both are quality control activities to determine whether products meet the design std. and spec.

Includes at process and plant levels

• Includes at process and plant levels
• Process level – manipulating input and parameters of the process.
• Plants level – labor, maintenance, costing, shipping, scheduling etc.

4 keys parameters:

• 4 keys parameters:
• i. Quality
• ii. Variety
• iii. Complexity of assembled products.
• iv. Complexity of individual parts.

If no = Num. of distinct operation through which work units are routed.

• If no = Num. of distinct operation through which work units are routed.
• To increase/decrease prod. Capacity:
• i. Short term:
• changes of S and H will increase prod. Capacity
• ii. Long term
• to increase capacity, change n, increase Rp and reduce no.

• PC = n SH Rp / no
