1.  GENERAL INFORMATION

1.1       1.1 Purpose
Feasibility studies are preliminary investigations into the potential benefits associated with undertaking a specific activity or project. The main purpose of the feasibility study is to consider all factors associated with the project, and determine if the investment of time and other resources will yield a desirable result. When a business is considering a new operation or the launch of a new product, the feasibility study is a logical tool to employ before any resources are invested in the new project. As a second major component, the feasibility study will also address costs and other factors that are indirectly associated with the project. The main purpose of feasibility study of Khulna Shipyard is to investigate, cost and benefit of current system using and cost and benefit of proposed system, and also to face constraints to reach to the destination.

2.  MANAGEMENT SUMMARY

2.1       Environment

Khulna Shipyard is involved with mainly ship building and repairing. It is operated by Bangladesh Naval Force. A naval officer (MD) takes the order by a bond signature after reaching a limit of desired profit. Whole system is based on pen and paper. Worker doesn’t have any modern amenity for ship building. It is also a government governed organization. So processing of any new change takes longer times.  But it is an established company for secured work with it.


2.2       Current Functional Procedures 
Khulna Shipyard (KSY) is governed by Bangladesh Navy (BN). Chief of the naval staff is the Chairman of the Board of Directors. Managing Director of KSY is directed by the Head of the Board of Directors. He is a Commodore of Bangladesh Navy. Four different division’s General Managers are supervised by Managing Director. Every General Manager is a Captain of Bangladesh Navy. The divisions are
1.    Design and Planning
In this division all designs are designed by Engineers and designers. A sub-division Design & Estimation is assist by Deputy General Manager, a naval officer who is responsible to the General Manager of this division.
2.    Administration
All administrative and commercial decisions are taken from this division. Deputy General Manager of Admin, Welfare & Training and Deputy General Manager of Commercial & Purchase sub-divisions are supervised by the General Manager of this division.
3.    Finance
General Manager of Finance is in charge of this division. Deputy General Manager of Accounts sub-division is supervised by him. All foreign and local financial works are derived from this division.
4.    Production
The major part of this organization is Production division. This division is consists of three sub-divisions. Engineering sub-division, Ship Building sub-division and Electrical sub-division are supervised by three different Deputy General Manager.
Each Deputy General Manager (DGM) supervises an Officer in Charge (OIC). Every officer in charge directs different sections. Permanent stuffs, casual staffs and workers work under these officers in charge. Total work is done in different sections. Total activity is done by four sections such as, “Lofting shop”, “Carpentry shop”, “Electrical shop” and “Machine shop”. Every requirement comes from root level of this organization.

Working procedure:

Whenever a client needs to repair or build a vessel, Khulna Shipyard follows a well defined procedure to serve the client. This procedure is depicted by the flow-chart below
If the owner of vessel agreed with Khulna shipyard to build or repair their vessel with the proposal cost and dates then the building or repairing procedure begin. A doc is prepared to build the ship or vessel. On the other hand for repairing a ship at first the ship or vessel is brought to the shipyard and is docked to the shipyard doc by some technical approach. By this time a tender is called by the Shipyard administration for buying the raw materials. Local and International companies participate to the tender and after getting a satisfactory price of the material, Khulna shipyard purchase those item. Purchased items are distributed to the corresponding shop. After getting the design and permission from design and planning section the building or repairing procedure begin. Generally a JCO (junior Commissioned Officer) gets the responsibility for every ship or vessel. After successfully building or repairing the vessel or ship, it is hand over to the owner and launched from the shipyard.






2.3       Cost analysis of current system:
At present there are 1600 workers and 100 office staff. Cost of current system using is analyzed as follows:

Place of expense
Salary(TK.)
MD
45000
GM
40000
DGM
35000
Engineer
30000
Office staff(total)
200000
Worker(total)
500000
Total
850000

The above is a monthly analysis of cost of KSY maintaining system. It is a large amount compared to   computer controlled maintenance.

2.4       Functional Objectives 
Automated machinery will take a major advantage for increasing production. This is a new concept. Considering these our estimated work can be fully done within 24 months.

2.5       Performance Objectives

Though current system requires 850000Tk. for office maintenance our current proposed system requires only 200000 tk. for first time and monthly 20000 tk. for engineer. And our system will enhance working rate and less time consumption and also raise production almost double. No. of workers will possibly be made half of present time and production can be raised to double.


2.6       Assumptions and Constraints

The operation of proposed system will not possibly end in any time. But if technology is advanced large enough then our proposed system may need to change.  There is no financial constraint compared to present once.





2.7       Methodology 

The main methodology used for proposed system is surveying to arrive at feasible alternative.  A manpower managing officer helps us take the survey. After surveying whole system we found that whole system management has a crying need for computer controlled management system. That can be database of employee and database of raw materials. A graphical user interface can make the total system attractive and easier to use.


2.8       Recommendation

We recommend use computer with a WAN connected. If it is done then communication between different sections will take less time thus working hour will increase. We also recommend use computer database for office and raw material maintenance. It will improve not only in time but also lessen company maintenance cost. We also recommend about using a website with marketing facility. This will attract buyer to buy ship or repair ship. Saying in one word our proposed system contains no serious problem and is more elastic compared to present one.

3.  Proposed System

We proposed to use computer with WAN connected for better communication among workers and staff. We also proposed to use database for employers and store goods for quick and elastic operation. We also proposed to use web based marketing system that’s why buyer can place order on online. This will attract more buyers to buy product. Another proposal was to use computer aided security device and computer aided instruments for ship building. These will help to improve performance of ship building and repairing. Though current system requires 850000Tk. for office maintenance our current proposed system requires only 200000 tk. for first time and monthly 20000 tk. for engineer. And our system will enhance working rate and less time consumption and also raise production almost double.




4.  Alternative Systems

We also recommend using centrally maintained database system for all employers and store goods. And also propose alternately of our proposed system to use modern ship building amenities.  But alternative system may not be possible to improve time performance.
