- Question 2: You have to transport 120 000 tons of bulk from Rio de Janeiro to Dhank (Oman) via the port of Sohar in containers. This bulk cargo has a S.G. (Specific Gravity) of 0,70. The internal measures of the container are: In feet Length Width Heigh 20ft container 19’7” 8’ 8’6” 40ft container 39’7” 8’ 9’6” The price for a 20ft container from Rio to Sohar is EURO 1400,- The price for a 40ft container from Rio to Sohar is EURO 1520,-- Max. payload for both a 20ft and 40ft container is 28 tons Post haulage between Rotterdam and Dhank (Oman) is EURO 150,-- per 20ft or 40ft container. What type of container will you choose for this concept and why? a) Volume calculation b) Maximum payload calculation c) Price per ton calculation d) Choice of container with justificationOptimization problem: An open top container of length L, width W and height H is used to transport ore. The cost for the surface area is $ 100/m2; cost of weld is $ 10/m; 400 m³ of ore is to be transported in no more than 50 trips; the length is not to exceed 3 m and width not to exceed 2 m. Formulate the optimization problem to solve for the maximum volume of the container.An airport needs a modern material handling system for facilitating access to and from a busy maintenance hangar. A second-hand system will cost $75,000. A new system with improved technology can decrease labor hours by 20% compared to the used system. The new system will cost $150,000 to purchase and install. Both systems have a useful life of five years. The market value of the used system is expected to be $20,000 in five years, and the market value of the new system is anticipated to be $50,000 in five years. Current maintenance activity will require the used system to be operated 8 hours per day for 20 days per month. If labor costs $40 per hour and the MARR is 1% per month, which system should be recommended?

Find the number of trucks of each type that the plant should rent so as to minimize cost. Type A Type B Minimum Cost Note: Input numerical values only. Page 3209. A rigging job calls for lifting a structure that weighs 150 tons. Two cranes are available, one with a rated capacity of 85 tons and the other with a rated capacity of 120 tons. The total weight of the rigging required to make the lift is 15 tons, of which 10 tons is to be carried by the larger crane and 5 tons is to be carried by the smaller crane. If the cranes are to be loaded in proportion to their net capacities, what should be the approximate net load on the 120-ton crane? A. 85 tons B. 44 tons C. 56 tons D. 63 tons
