Question 3: (15 marks) A solid waste collector assigned by Be'ah Company in Muscat-Oman plans to locate a disposal site near a commercial area. The collector would like to use a hauled container system rather than stationary system to collect the quantity of solid waste as generated in 2030 (from previous question Q2) with a density of 100 kg/m3 and container size of 7.2ft3/trip. Two containers for each trip and container utilization factor of 0.7. However, this only valid if the cost of haul system is OMR 32.2 less than the other system. What is the maximum distance (X) away from the commercial area that the disposal site can be located so that it makes the above assumption valid? Confirm whether the collector spent 15% of each 8-hour workday on off-rout or not if the average time spent driving from corporation yard to the first container and from last container to corporation yard are 20 mins and 15 mins, respectively. Support your answer with the proper demonstration. Hauled container System Stationary Container System Container pick up time ;0.07 h/trip Collection vehicle capacity (4 x 5 x 2 feet) Container unloading time; 0.065 h/trip Collection vehicle compaction ratio = 2 At site time s = 0.062 h/trip Container unloading time, 0.06 h/container Overhead costs = OMR 108.8 /wk Overhead costs = OMR 290.5 /wk Operational costs = OMR 5.5 h/trip Operational costs = OMR 6 /h of operation At-site time = 0.4 h/trip Average time spent driving between container locations =0.087 h/location Constants for estimating haul time as 0.033 h/trip and 0.033 h/mi Question 3: (15 marks) A solid waste collector assigned by Be'ah Company in Muscat-Oman plans to locate a disposal site near a commercial area.
