| SEMESTER | 4 |
| BK ID | |
| CREDITS | 4 |
| MARKS | 60 |
Note: Answer all questions. Kindly note that answers for 10 marks questions should be approximately of 400 words. Each question is followed by evaluation scheme.
Q.1 Write short notes on:
- PPC for batch production
- Production control systems
- Importance of forecasting
- Inventory costs
Ans : PPC for batch production :
A variety of products are made but volume is not too large, to demand a separate line for each product. Here, items are processed in lots or
Production control systems :
A production control system is concerned with planning and controlling all aspects of manufacturing, including materials, scheduling machines and people, as well as coordinating suppliers and customers. An effective production control system is critical to the success of any company. A control system is a device, or
Importance of forecasting :
Forecasting is the process by which companies ponder and prepare for the future. It involves predicting the future outcome of various business decisions. This includes the future of the business as a whole, the future of an existing or proposed product or product line, and the future of the industry in which the business operates, to
Inventory costs:
Inventory consists of the products that a company has stored for resale to its customers. Inventory can be separated into three categories: raw materials, semi-finished goods and finished goods ready for sale. Purchasing, processing,
Q.2 Explain in brief about priority rules for scheduling.
Ans : Priority rules
A priority rule contains information to construct a list of activities that ranks all project activities in a certain order to determine the priorities in which the activities are assigned to the project schedule. Such a list is constructed based on the project data in order to assign priorities to activities, as follows:
Q.3 Describe computer aided manufacturing.
Ans : Computer aided manufacturing :
Computer-aided manufacturing (CAM) is the use of computer software to control machine tools and related machinery in the manufacturing of work pieces. This is not the only definition for CAM, but it is the most common; CAM may also refer to the use of a computer to assist in all operations of a manufacturing plant, including planning,
Q. 4 Write short notes on:
- Backward scheduling
- Application of FMS in industries for exclusive parts
- Need of synchronous manufacturing
- Long term capacity planning
Ans: Backward scheduling :
Method of determining a production schedule by working backwards from the due date (or time) to the start date (or time), and computing the materials and time required at every operation or stage. Both material requirements
Application of FMS in industries for exclusive parts :
An Industrial Flexible Manufacturing System (FMS) consists of robots, Computer-controlled Machines, Numerical controlled machines (CNC), instrumentation devices, computers, sensors, and other stand alone systems such as
Need of synchronous manufacturing :
In synchronous manufacturing, production occurs in different production centers; some centers have constraints that limit the rate of production and some centers do not. Both types of centers must focus on using raw materials to produce goods that are nearly ready for shipment to customers, with the
Long term capacity planning:
Over the long term, capacity planning relates primarily to strategic issues involving the firm’s major production facilities. In addition, long-term capacity issues are interrelated with location decisions. Technology and transferability of the process to other products is also intertwined with long-term capacity planning. Long-
Q.5 Explain aggregation techniques
Ans : Definition of aggregation techniques:
Aggregate planning is an operational activity that does an aggregate plan for the production process, in advance of 2 to 18 months, to give an idea to management as to what quantity of materials and other resources are to be procured and when, so that the total cost of operations of the organization is kept to the minimum over that period..
Q.6 Explain make or buy decisions and when it is appropriate to consider each,
Ans : Explanation of make or buy decision :
The act of choosing between manufacturing a product in-house or purchasing it from an external supplier. In a make-or-buy decision, the two most important factors to consider are cost and availability of production capacity. An enterprise may decide to purchase the product rather than producing it, if is cheaper to buy than make or if it does not have sufficient production capacity to produce it in-house. With the phenomenal surge in global outsourcing over the past decades, the make-or-buy decision is one that
