Make a neat sketch of a logic diagram using CYCLONE notation for the pile driving operation shown below. The operation consists of three main steps. First, an auger bores a hole into the soil approximately 6 meters deep by 0.6 meters in diameter. This takes about 16 minutes per hole, of which 12 minutes are actual boring and 4 minutes are repositioning and setup. Second, a mobile crane fetches a 6-m pile and drops it into the hole. This takes about 4 minutes, of which 1 minutes is placing the pile in the hole. After 5 holes and piles are ready, an 8-m3 transit-mix truck arrives and places lean concrete into the holes. This takes about 2 minutes per hole, plus 1 minute to position or reposition each hole, for a total of 15 minutes to unload the truck. The truck (assume there is only one truck) then takes 45 minutes to go back to the batch plant and return with another load of concrete. (This problem is taken from Computer Applications in Construction, By B.C. Paulson, McGraw-Hill, Inc., 1995) Simulate the operation for a shift length of 8 hours and compute the production. Discuss productivity and bottlenecks of the operation. Analyze utilization of each piece of equipment Set soldier Place lean concrete ple Auger hole New building site
