Explain why it is important to model the context of a system that is being developed. Give two examples of possible errors that

Sedbober [7]

Answer:

Explanation:

System models are created and used in order for all of the individuals involved in the process to be able to see exactly how each module that is being created connects to the rest of the system. This allows every developer to understand each module's/part's function and develop it with the entire system in mind. This also makes it easier to implement newer features. If a model is not made then the developers may miss key features and when it is time to piece all of the components of the system together, the overall process can become a jumbled mess.

Describe and compare the characteristics of (a) proportional control, (b) proportional plus integral control, (c) proportional p

stira [4]

Answer:

The answer is below

Explanation:

1. Proportional Control is a form of control engineering in which an output is directly proportional to the error signal.

Characteristics of proportional control are:

* It is utilized when the deviation between the input and output is small

* It is also utilized when the deviation is not sudden.

* It reduces steady-state error

* It speeds up the response of the overdamped system

2. Proportional plus Integral Control is a form of control engineering in which a collective proportion and integral control of the output is equivalent to the combined proportion and integral of the error signal.

Characteristics of proportional plus integral control are:

* it can revert the controlled variable to the original set point

* It decreases steady-state error

* It quickens up the reaction of the overdamped system

3. Proportional plus integral plus derivative control is mostly applicable in operating the process elements such as temperature, pressure, speed, etc. It is recommended for industrial use.

Characteristics of Proportional plus integral plus derivative control are:

* It enhances the temporary reaction of the system.

* It also lessens steady-state error

* It accelerates the response of the overdamped system

A product whose total work content time = 50 min is assembled on a manual production line at a rate of 24 units per hour. From p

valentinak56 [21]

Answer:

a)Cycle time = 2.37 min

b)Numbers of workers =21

c)Stations on the line =24

Explanation:

Given that

Total work content time(TWC) = 50 min

Production rate Rp= 24 units/hr

manning level will be close =1.5

Line balancing efficiency =0.94

Cycle time

$T_c=\dfrac{60E}{R_P}$

$T_c=\dfrac{60\times 0.95}{24}$

Cycle time = 2.37 min

Numbers of workers ,W

$W=\dfrac{TWC}{T_c}$

$W=\dfrac{50}{2.37}$

W= 21

Numbers of workers =21

Stations on the line(n)

Lets find service time Ts

Ts = Cycle time - Time for repositioning

Ts = Tc- Tr

Ts= 2.37 - 9/ 60 min

Ts= 2.22 min

We know that efficiency

$\eta=\dfrac{TWC}{n.T_s}$

$0.94=\dfrac{50}{n\times 2.22}$

n=23.94 ⇒n=24

n=24

Stations on the line =24
