Case Study on Optimizing of CNIC processing at NADRA office

Wah Cantt using Arena

Abstract:

Discrete event simulation is the process of designing a representative model of a real system and

conducting experiments with that model. For purpose of either understanding the behavior of the system

or evaluating different proposed strategies for the operation of a system, discrete event simulation is a

tool suitable for the study of systems and improves the overall efficiency. Arena is a discrete event

simulation and automation software developed by Systems Modeling and acquired by Rockwell

Automation. It uses the SIMAN processor and simulation language in this work, the existing production

system of NADRA office is studied and utilization of each resource is analyzed. This survey attempts

to reduce the Queue and improve the performance of NADRA. All necessary data were gathered

through visiting the Office and registering the observations. Simulation model was designed using

Arena software.

Introduction:

National Database and Registration Authority (NADRA) charged with the establishment of a

new registration system for the entire population of Pakistan. NADRA is one of the leading

System Integrators in the global identification sector and boasts extensive experience in

designing, implementing and operating solutions for corporate and public sector clients.

Basic Explanation:

NADRA is one of the leading System Integrators in the global identification sector and boasts

extensive experience in designing, implementing and operating solutions for corporate and

public sector clients. NADRA offers its clients a portfolio of customizable solutions for

identification, e-governance and secure documents. NADRA has successfully implemented the

Multi-Biometric National Identity Card & Multi-Biometric e-Passport solutions for Pakistan,

Passport Issuing System for Kenya, Bangladesh High Security Driver’s License, and Civil

Registration Management System for Sudan amongst other projects.

Problem Statement:

NADRA office located at Aslam Market, Wah Cantt. The branch manager want to improve the

system of the CNIC processing. Customers arrive according to the following schedule:

Incoming customers are distinguished according to their types: i.e. 20% customers are arriving

individually, 70% are arriving in pairs (say couples) and the remaining customers are arriving

in the form groups (mostly of three). Following arrival, each incoming customer type proceeds

as a separate entity. Moving further customers are distinguished according to the service they

want to earn from the respective servers. 70% of the customers are those that want new ID

card, this type of customers are directed to the token counter, 10% of the customers are those

that are coming to get the necessary information for CNIC processing, these customers are

further distinguished among male and female customers. The remaining 20% of the customers

are those that are coming to collect their ID card, these customers are further distinguished

among male and female customers before directed to the card delivery counter. 95% of the

customers moved on to the next servers for further processing and the remaining 5% customers

are rejected due to the unavailability of the necessary documents required for the CNIC

processing. After getting token, customers wait in the waiting area until his/her turn when the

server is free to serve them.

Customers move towards the photographer where photographer clicks a picture of the customer

and sent it to the next server. Picture process time is uniformly distributed as UNIF (6, 6.5)

minutes. Customers move towards the server that enters the bio data of the customer and sent

it to the next server. Data Entry time is a Constant 7 minutes. Customers move towards the

server that takes the signatures and fingers impression for CNIC of the customer and sent it to

the next server. Signatures and fingers impression time is Constant 8 minutes. Customers move

towards the server that deliver the complete printed form to the customer for attestation. Form
