Question No: 21 ( M a r k s: 5 )
Differentiate between the following:
Computer Aided Design and Computer Aided Manufacturing
Answer:
Computer Aided Design (CAD):
“It is a system that enables drawings to be constructed on a computer screen and subsequently stored, manipulated and updated electronically.”
The ability to rotate or create movement in the design allows testing for clearances and frequently reduces the cost of prototyping the products. The technology is used for a wide variety of products in such fields as architecture, electronics, and aerospace, naval, and automotive engineering. Although CAD systems originally merely automated drafting, they now usually include three-dimensional modeling and computer simulated operation of the model. Rather than having to build prototypes and change components to determine the effects of tolerance ranges, engineers can use computers to simulate operation to determine loads and stresses. For example, an automobile manufacturer might use CAD to calculate the wind drag on several new car-body designs without having to build physical models of each one. In microelectronics, as devices have become smaller and more complex, CAD has become an especially important technology. Among the benefits of such systems are lower product-development costs and a greatly shortened design cycle. While less expensive CAD systems running on personal computers have become available for do-it yourself home remodeling and simple drafting, state-of-the-art CAD systems running on workstations and mainframe computers are increasingly integrated with computer-aided manufacturing systems.
Computer Aided Manufacturing (CAM)
Computer-aided manufacturing (CAM) is a form of automation where computers communicate work instructions directly to the manufacturing machinery. The technology evolved from the numerically controlled machines of the 1950s, which were directed by a set of coded instructions contained in a punched paper tape. Today a single computer can control banks of robotic milling machines, lathes, welding machines, and other tools, moving the product from machine to machine as each step in the manufacturing process is completed. Such systems allow easy, fast reprogramming from the computer, permitting quick implementation of design changes. The most advanced systems, which are often integrated with computer-aided design systems, can also manage such tasks as parts ordering, scheduling, and tool replacement. It is a system that uses computer aided techniques to control production facility. Some of these techniques are o Computer-aided process planning – Use of computer to control activities and functions to prepare a detailed set of plans and instructions to produce a machine or part. – Machines
-
Robotics programming – The science or study of the technology associated with the design, fabrication, theory, and application of robots. – Automobile industry.
Question No: 22 ( M a r k s: 10 )
Discuss different phases of decision making process in detail
Question No: 22 ( M a r k s: 10 )
Discuss different phases of decision making process in detail.
Answer:
Phases of decision-making process are:
• Intelligence – searching for conditions in the environment that call for decisions
• Design – inventing, developing, and analyzing possible courses of action
• Choice – selecting a course of action from those available
• Implementation – implementing the selected course of action
• Monitoring – checking the consequences of the decision made after implementation.
The Intelligence Phase
Scan the environment to identify problem situations or opportunities. Conditions that call for decisions are identified. Typical Activities include:
• Country Risk based on following
o Country credit rating
o Transparency
o Corruption
• Facilities for one window operation (levels of bureaucracy)
o SRO Culture
o Govt. Policy
o Law & Order
o Exchange rates
For instance, international banks while entering into country make assessment of exposure and thus limit the maximum number of transactions the bank can undertake.
a) What are the possible advantages, disadvantages, and risks?
b) How much resources will be diverted from other activities?
c) When should we start? And so forth.
The Design Phase
Possible courses of actions are invented, developed, and analyzed.
Typical Activities include:
Select criteria for assessing the alternatives (e.g., ROI, market share, etc.)
• Create alternatives: invest now, invest later, do not invest
• Analyze levels and timing of investment
• Information flow for decision making
• Prepare a feasibility study
• How will the choice be made, by whom, and when?
The Choice Phase
A course of action is selected out of the available alternatives as devised in the
design phase. Typical Activities include:
• Get information
• Final evaluation
• Sensitivity analysis
16.5 The Implementation Phase
Implement the selected course of action. Typical Activities include:
• Follow the implementation plan
• Deal with resistance to change and necessary approvals and authorizations
• Conduct training
• Transfer resources
