ABSTRACT

We as economic analysts are evaluating thefeasibility of establishing a new company. B-Safe is a company focusing on the aviation safety belt industry. We are going to calculate if this business plan of ours can be accepted or not. We will use the Present Worth method to conduct our analysis.

B-SAFEIntroduction

B-Safe is a company aspiring to launch itself as an aircraft seatbelts manufacturer. They possess a unique ambition to be the first provider of seatbelt airbag systems and a range of other safety restraint products for the aerospace industry. They want to be one of the most advanced companies for aviation safety in the world.

They intend to manufacture products used in both commercial and general aviation, in civilian applications, and that can be found in automotive child seats too. Protecting passengers is a priority to B-Safe and hopefully their products should help move millions of people and countless tons of cargo safely and securely in the air and on the ground. These are some of their potential products:

Seatbelt Airbag System Cargo Containment Solutions Child Seat Restraints Aviation Passenger & Crew Restraints Aircraft Interior Safety

B-Safe is focused and committed to providing quality products and timely, cost-effective solutions to customers worldwide.

Present Worth of CostsAnnual Cost of Raw materials = Annual cost of [Aluminium + Steel + Nylon + Nitrogen + Polyesters]

= $2,158,200

MARR = 20%

Inflation = 1.5%

MARR f =i +f +if

= 20 + 1.5 + .3

= 21.8%

Present worth of Raw materials = $2,158,200 (P/A, 21.8%, 20)

Annual Cost of Utilities = Annual cost of [Electricity + Water]

Annual Operational Costs = Annual cost of [Scientists, Engineers, Workers, Security]

= $30,518,641.92

Annual Miscellaneous Costs = Annual cost of [Machine maintenance, Transportation]

ConclusionSo, after doing the analysis, we come to a conclusion that they should do this investment on making a new company. This statement also being strongly supported by the positive result of the net present worth. This positive result means that the project is acceptable and if they do this project, hopefully they will success and get good profits.
