A northern hardware company is studying a plan to open a new distribution center in southeast. The company plans to rent a warehouse and an adjacent office, and distribute its main products to the local dealers. The company has decided to initially start with four of its main products: Pressure washers, Go karts, Generators, and Water pumps. The company s finance department has notified the management that such an investment is advised only if the new facility generates at least a net profit of $400,000 in the first year of its operation.
The company estimates that the monthly rent and utilities will be about $20,000. Also, the management plans to sign a contract with a local company to rent a number of forklifts for a monthly fee of $1,500. Furthermore, the company estimates that it will have to spend an additional $420,000 annually to hire a manager, a secretary, and five full time employees. The table below describes how much each of the products cost the company (including transportation costs):
Item Cost in dollars
-
- Pressure washer $320.00
-
- Go-kart $380.00
-
-
Generator $410.00
-
-
- (Case of 5 Water Pumps) $645.00
The company has set aside a budget of $170,000 for merchandise each month to be sent to the new location. The selling prices (per unit) for each item are given below:
Item Selling price
-
- Pressure washer $499.99
-
- Go-kart $719.99
-
- Generator $699.99
-
- Water pump $269.99
Other than the budget, another of the company s concern is the available space in the warehouse. The warehouse has 82 shelves and each shelf is 30 ft long and 5 ft wide. Pressure washers and generators each are stored on 5 ft by 5 ft pallets whereas each Go Kart is stored on an 8 ft by 5 ft pallet. Furthermore, a 5 ft by 5 ft pallet is used to store four cases of water pumps (there are five water pumps in each case).
For promoting its brand products, the company s marketing department has decided to allocate at least 30% of its inventory to pressure washers and Go Karts, and sell at least twice as many generators as water pumps.
Perform a monthly analysis using a linear programming model. Then determine whether the company should open its new branch in southeast.
