1.12) Humans are needed even in highly manufactured industries for works like learning, evaluating, engineering, decision making, managing and few more functions. And also text identifies that four methods of works are possible in which humans are needed. They are a) Equipment maintenance b) plant management c) Engineering project work and d) Programming & computer operations.
1.13) USA refers to a) Understanding existing process, b) Simplifying the existing process, c) Automating that process. It is a common sense method for automation projects. Procedures similar to this process is recommended for automation and manufacturing trade literature, but this approach stands unique.
1.16) Three phases of automation migration strategy includes:

Review Questions:
2.7) Hard product variety refers to the products that varies substantially and the soft product variety is when there is a small variation between the products.
2.10) Single model production line refers to the products that are identical and there is no variation in products that are made on the line. Mixed model production line refers to the products that has soft variety in the products that are made on the line.
2.11) Technological processing capability refers to the available pair of manufacturing processes. It is closely related to materials being processed while certain manufacturing process is suited 10 materials while others are suited to other materials.
Problems
2.1) a. Different product models, P= (3+5+7) = 15 models
b. Total quantity of products produced annually, Q= (3*400) + (5*800) + (7*500) = 8700 units
2.2) a. Total number of components produced = 3*400*46= 55200 components
b. Total number of operations performed in the plant annually = 55200 * 3.5 = 193200 …show more content…
With the receipt of interrupted signal the computer system shifts to other predetermined subroutine that was made to deal with particular interrupt.
5.16) Programmable logic controller is an microprocessor based controller that utilizes stored instructions in a programmable memory to execute sequencing, logic, counting, arithmetic control and timing functions to control machines and processes. PLC’s are used for discrete control and continuous control applications in discrete manufacturing and process industries.
5.18) Programmable automation controller is a term derived for small and local control systems. It differs from PLC by programming interface. Some of the features of programmable automation controller is the high investment for general purpose equipment, flexibility to deal with the changes in product configuration, lower production for fixed automation, it is most suitable for batch
