Q.1. An automated storage/retrieval system installed in a warehouse has five aisles. The storage racks in each aisle are 40 ft high and 160 ft long. The S/R machine for each aisle travels at a horizontal speed of 288 + PQ ft/min and a vertical speed of 44 + P ft/min. The pick and deposit time = 0.2 +(Q/100) min. Assume that the number of single command cycles/hr is twice to the number of dual command cycles/hr and that the system operates at (70 + P) % utilization.Determine the throughput rate (loads moved/hr) of the AS/RS.Q.2. An AGVS (Automated Guided Vehicles) will be used to satisfy the material flows indicated in the from-to chart in Table 1 below, which shows deliveries per hour between stations (before the slash) and distances in meters between stations (after the slash). Moves indicated by "L" are trips in which the vehicle is loaded, while "E" indicates moves in which the vehicle is empty. It is assumed that availability = 0.7+ (PQ/1000), traffic factor = 0.83+ (Q/100), and efficiency = 0.9. Speed of an AGV = 1+ (QP/100) m/s.If load handling time per delivery cycle = 1.0 +(PQ/1000) min, determine the number of vehicles needed to satisfy the indicated deliveries per hour. NA means "Not Available".Table.1To1234From10/09L/907L/1205L/7525E/900/00/NA4L/8037E/1200/NA0/00/NA49E/750/NA0/NA0/0


Assignment 3Discrete material handling Submit a clear typed solution paper (Neat hand writing may accepted in certain conditions) Avoid Plagiarism Note: 1. Students should not directly copy the answers from the study guide and they should write all the answers on their own word. 2. Marks will be deducted for poorly organised/explained solutions. Refer to section in course material regarding appropriate setting out format. 3. This work is individual; students can work as a group, but reference each other. Plagiarism and repeated work will result zero mark. 4. Notice: use lecture notes and lecturer hints. 5. P&Q are the second last pair digits of your student ID (ie Student ID 1234 PQ 78). Q.1.
