Description
Lippelli Warehouses requires an electrical system for measuring their operational workers whilst they are on the job.
The system is to monitor some specific attributes of each worker and directly use that information to grade the worker in relation to another worker.
Requirements
The system must accept from the user: the quantity produced by the worker, class of work of the worker, the mode of grading scheme to be used and display a Quality Level grade for that worker. It should perform this operation every six (6) seconds and needs to store the information for the last worker in order to get its results.
Inputs from each worker
For each worker the system requires three (3) forms of inputs which becomes that worker's attributes. They include: -

1.Product Quantity (Decimal Integer represented in Binary)
This numeric value represents the amount of units of the products that the worker has produced at the time system input. It is measured in pounds (lbs) and can range from 0 to 25 inclusive.

2.Class of Work (Decimal Integer represented in Binary)
This numeric value represents the class of work that the worker produces. 1 are Technical workers, 2 are Digital workers, 3 are Mechanical workers, 4 are Middleware workers and 5 are Electrical workers.

3.Quality of Work (Letter Value represented in Binary of the previous worker)
This symbol represents the quality of work that the current worker is known for. The values are: A (Best quality), B (Par quality) and C (Poor quality).

Outputs of the system
The system will display an output that will represent the current quality level of a worker based on their attributes as well as the attributes of their peers.
The three different values of the output will represent: -

1.Best Quality (A) – which means that the workers are producing the highest quality products

2.Par Quality (B) – which means that the workers are producing at the global standard level

3.Poor Quality (C) - which means that the workers are producing below Par Quality

Timing Process
The system is to ensure that it checks the current worker's attributes against the last worker's attributes every 6 seconds in order to produce the quality level of the current worker. There must be no other way of producing these results based on the input apart from the six (6) seconds to ensure that the process is periodical and efficient.
At every six second interval the system is to perform one of the three grading schemes listed below based on the inputs and the criteria available to it.

Modes of Grading Schemes
There are three (3) major kinds of grading schemes used by the required system on the inputs/attributes of the workers to make the correct display of Best (A), Par (B) or Poor (C)

Quality for the current worker.
In order for the system to grade the current worker it also requires the attributes for the last worker to be processed by the system (i.e. the system must have some way of storing the current worker's attributes to be compared against the next worker).
The first worker to be processed by the system always gets a grade of Par Quality (B) because there is no worker to compare them to.
The following explains how the three (3) different modes of grading schemes work: -

1.Class Grading Scheme. This grading scheme focuses of the different classes of the current and previous workers. It uses the following table to determine the grade of the current worker:
Current Worker - Previous Worker - Grade
Technical - Technical, Digital, Mechanical, Middleware - B
Technical - Electrical - A
Digital - Technical, Digital, Mechanical, Middleware, Electrical - A
Mechanical - Technical - C
Mechanical - Digital - B
Mechanical - Mechanical, Middlewarem Electrical - A
Middleware - Mechanical, Electrical - A
Middleware - Technical, Middleware - B
Middleware - Digital - C
Electrical - Electrical, Digital, Mechanical, Middleware - B
Electrical - Technical - A

2.Quality Grading Scheme. This grading scheme focuses on the quality given to the last/previous worker in relation to the current worker. If the previous worker has a Quality Level of Best (A) then the current worker gets a Quality Level of Best (A) if their quantity is greater than 10 lbs. If the previous worker has a Quality Level of Par (B) then the current worker gets a Quality Level of Best (A) if their quantity falls within the range of 5 to 20 inclusive. For all other cases the current worker gets a Quality Level of Poor (C).

3.Quantity Grading Scheme. This grading scheme focuses directly on the amount of production of the current and previous workers. The current worker gets a Quality Level of Best (A) if they produce more lbs than the previous worker; Par (B) if they produce the same amount of lbs as the previous worker and Poor (C) if they produce an amount below the previous worker's.

NEED HELP URGENTLY FAILED THIS ASSIGNMENT BUT STILL NEED TO BETTER UNDERSTAND IT. MAY I GET SOME ASSISTANCE ASAP. THANKS!
 
How do I create the circuit for the Operational Pair Grading System above? View the attachments below for wat i had done. Thanks!
