Question

Two production facilities create devices, each device is tested at the same location. The devices arrive at random times and are dealt with in order of their arrival. The testing facility then sorts them into collections of three types: Grade A, (top 10%), Grade B(next 60%), Grade C(lowest 30%). Use a uniform distribution to determine the quality of any particular device. Each of these are then sorted into sales bundles (lists), Grade A under their own label, Grade B are sold under a different, label and the last grade are sold as a discount brand. Create a simulation of this process.

Problem.

Two production facilities create devices, each device is tested at the same location. The devices arrive at random times and are dealt with in order of their arrival. The testing facility then sorts them into collections of three types: Grade A, (top $10\%$ ), Grade B(next $60\%$ ), Grade C(lowest $30\%$ ). Use a uniform distribution to determine the quality of any particular device. Each of these are then sorted into sales bundles (lists), Grade A under their own label, Grade B are sold under a different, label and the last grade are sold as a discount brand. Create a simulation of this process.

Solution.

#include<iostream>
#include <cstdlib>
#include <ctime>
#define TIME 1000
using namespace std;
int main() {
    int line1 = 0;
    int line2 = 0;
    int currTime = 0;
    int itemA = 0;
    int itemB = 0;
    int itemC = 0;
    srand(time(NULL));
    while (TIME >= line1 && TIME >= line2) {
        // Check which line should produce new item
        if (line1 == currTime) {
            line1 += rand() % 10 + 1;
            int item = rand() % 10 + 1; // Simulation of item type
            if (item <= 1) {
                cout << "Time: " << line1 << " Item: A" << endl;
                itemA++;
            } else if (item >= 2 && item <= 7) {
                cout << "Time: " << line1 << " Item: B" << endl;
                itemB++;
            } else {
                cout << "Time: " << line1 << " Item: C" << endl;
                itemC++;
            }
        }
        if (line2 == currTime) {
            line2 += rand() % 10 + 1;
            int item = rand() % 10 + 1; // Simulation of item type
            if (item <= 1) {
                cout << "Time: " << line2 << " Item: A" << endl;
                itemA++;
            } else if (item >= 2 && item <= 7) {
                cout << "Time: " << line2 << " Item: B" << endl;
                itemB++;
            } else {
                cout << "Time: " << line2 << " Item: C" << endl;
                itemC++;
            }
        }
        // Determine time when next event happens
        if (line1 < line2) {
            currTime = line1;
        } else {
            currTime = line2;
        }
    }
    cout << "A: " << itemA << " B: " << itemB << " C: " << itemC << endl;
