Question

Problem-1 Suture Packaging Sutures are strands or fibers used to sew living tissue together after an injury or an operation Packages of sutures must be sealed carefully before they are shipped to hospitals so that contaminants cannot enter the packages The object that seals the package is referred to as a sealing die Generally, sealing dies are heated with an electric heater For the sealing process to be a success, the sealing die is maintained at an established temperature and must contact the package with a predetermined pressure for an established time period The time period in which the sealing die contacts the package is called the dwell time Assume that the acceptable ranges of parameters for an acceptable seal are the following: Temperature 150-170°C 60-70 psi (pound per square inch) Pressure Dwell Time: 2-2.5s A data file named suture. dat contains information on batches of sutures that have been rejected during a week period. Each line in the data file contains the batch number, the temperature the pressure, and the dwell time for a rejected batch As a quality control engineer your goal is to analyze this information to determine the percentage of batches rejected due to temperature, the percentage rejected due to pressure, and the percentage rejected due to dwell time. If a specific batch is rejected for more than one reason, it should be counted in all applicable totals 1. Create a MATLAB script to compute and print the percentage and the total number of batches rejected in each category 2. Some of the batches were erroneously rejected. Provide the commands to determine those batches return their batch numbers and the total number of batches that should have actually been rejected.

Explanation / Answer

bring the suture.dat file in the matlab directory and then run the following program

A=load(suture.dat);

l=length(A);

count=0;

for i=2:l

if A(i,2)>=150 && A(i,2)<=170

count1=count+1;

end

if A(i,3)>=60 && A(i,3)<=70

count2=count+1;

end

if A(i,4)>=2 && A(i,4)<=2.5

count3=count+1;

end

end

PRT = (l-count1)*100/l; % Percantage Rejected due to Temperature

RT = (l-count1); % Batches Rejected due to Temperature

PRP = (l-count2)*100/l; % Percantage Rejected due to Pressure

RP = (l-count2); % Batches Rejected due to Pressure

PRDT = (l-count3)*100/l; % Percantage Rejected due to Dwell Time

RDT = (l-count3); % Batches Rejected due to Dwell Time

for j=2:l

if A(j,2)==A(j+1,2)

if A(j,3)==A(j+1,3)

if A(j,4)==A(j+1,4)

B(j,:)=A(j,:);

B1(j,1)=j; % Batch number of the duplicate entries

end

end

end

end

len=length(B); % Total number of duplicate entries
