1. What are the area covered under production planning and control

Ans:

I. Materials: Planning for the procurement of raw materials, components and spare parts in the right quantities and specifications at the right time from the right source at the right place
II. Methods: Choosing the best method of processing from several alternatives (c) Machines and Equipment’s : Manufacturing methods are related to production facilities available in the production system.
III. Routing: Determining the flow of work material handling in the plant and sequence of operations or processing steps.
IV. Manpower : Planning for manpower having appropriate skills expertise
V. Estimating: Establishing the operating times leading to fixation of performance Standards both for workers and machines.
VI. Loading: it ensures maximum possible utilization of productive facilities and avoids bottlenecks in production.
VII. Scheduling : Scheduling ensures that the parts, subassemblies and finished products are completed as per required delivery dates
VIII. Dispatching: It is concerned with the execution of planning functions. It gives necessary authority to start a particular work which has already been planned under routing and scheduling
IX. Functions. It releases orders and instructions to start the production in accordance with the route sheets and schedule charts.
X. Inspection: It is related to maintenance of quality in production and of evaluating the efficiency of the processes, methods and labour so that improvements can be made to achieve the quality standards set by product design

2. What is the Function of PPC

Ans:

I. It provides a systematic step to be followed in making a product.
II. It helps in drawing a thin line between productions and controlling activities, which gives maximum usage of resources.
III. It ensures that manufacturing products are of good quality.
IV. It ensures that maximum utilization of all the resources to reduce the product throughput time.
V. It maintains higher range and flexibility in manufacturing operations, in order to provide good quality products.
VI. It helps in scheduling a sequence of operation for new product development and carry out effective measures for the same.
VII. It removes bottlenecks in production and controls the quantity production.
VIII. It provides a control over production in order to reduce the scrap and rework

3.Explain Job production

Ans:

Job production involves manufacturing of the products to meet specific customer requirements of special orders. The quantity is usually small. It is categorized accordingly to the type of regularity of manufacturing, namely a small number of products produced only once or a small number of products produced intermittently when the need arises, also a small number of products produced periodically at known interval of time.

4. Explain Batch production

Ans:

Batch production is the manufacturing of a number of identical articles either to meet a specific order or to satisfy continuous demand.
The decision regarding tooling , jigs and fixtures are dependent on the quantities involved in the production batch. In this process the batch may be produced only once. It may be produced repeatedly at irregular intervals, when the need arises. It can be produced periodically at known Intervals to satisfy continuous demands. Planning and controlling becomes more simplified as quantity increases and manufacturing becomes more regular. Two problems that may arise in batch production are due to size of batch and due to scheduling of production.

5.What is continuous Production and state its types.

Ans:

Continuous production is normally associated with large quantities of production and with a high rate of demand. It is justified when the rate of production can be sustained by the market.
There are mainly two types of continuous production
  I. Mass Production
  II. Flow Production.

6. What are the different types of Active Attack ?

Ans:

The rate at which the production of the company is carried out due to the planning activities that are finally controlled in order to fulfill its' objectives is known as degree of centralization. The degree of centralization mainly depends upon the PPC activities carried out centrally to attain the goals of the organization.

7. State Prerequisites of PPC

Ans:

I. Data Pertaining to Design
II. Data Pertaining to Equipment’s
III. Data Pertaining to Raw material
IV. Data Pertaining to Tooling
V. Data Pertaining to Performance standards
VI. Data Pertaining to Labour
