- Suppose a process has been monitored daily for the last ten days and the number of machine failures each day was noted. The results follow: Day Number: 1 2 3 4 5 6 7 8 9 10 Number of Failures: 8 9 6 10 12 4 9 11 9 12 Compute control limits for a c-chart that monitors the average number of machine failures per day. Is the process in a state of control?Using signavio or any PBM tools and must Use pool and lane and object. Model the following business process at a supplier. After a supplier notifies a retailer of the approval of a purchase order, the supplier can receive an order confirmation, an order change, or an order cancelation from the retailer. It may happen that no response is received at all. If no response is received after 48 h, or if an order cancelation is received, the supplier will cancel the order. If an order confirmation is received within 48 h, the supplier will process the order normally. If an order change is received within 48 h, the supplier will update the order and ask again the retailer for confirmation. The retailer is allowed to change an order at most three times. Afterwards, the supplier will automatically cancel the order.(Can someone help me with this just need a P&ID solution meeting the requirements and explanation. thx) INSTRUCTION: Given three bare processes develop a control system using feedbackand feedforward concept/principle.

- Speed reduction, either through gearing or belt-pulley constructs, is an important element in motion system design. Similarly, converting rotary motion to linear motion is an important consideration. Considering a printer system driven by a stepper motor with 200 steps per revolution, construct a table that shows the relationships for: a. Position resolution of the print head vs. angular position of the motor. This translates to addressable print dots per mm vs. step angle. b. Print head speed (mm/S) vs. motor speed (Steps/S with rpm also noted) C. Frictional load at the print head (mN) vs. reflected torque at the motor (mNM) Mass of the print head vs. reflected inertia to the motor d. Use GR for Speed Reduction, r (mm) for the radius of the drive pulley, and m (grams) for print-head mass.. Belt Actuator Load Drive Pulley Secondary Pulley Linear Guide Belt Primary Pulley Motor= Consider a four aisle AS/RS in which an S/R machine is used for each aisle. The length of the storage aisle 85 m and its height = 14 m. Suppose horizontal and vertical speeds of the S/R machine are 61 m/min and 23 m/min, respectively. The S/R machine requires 20 s to accomplish a P&D operation. The aisles in the AS/RS will be organized to follow a class-based dedicated storage strategy. There will be two classes, according to activity level. The more active stock is stored in the half of the rack system that is located closest to the input/output station, and the less active stock is stored in the other half of the rack system farther away from the input/output station. Within each half of the rack system, random storage is used. The more active stock accounts for 80% of the transactions, and the less active stock accounts for the remaining 20%. Assume that system utilization = 90%, and the number of single-command cycles = the number of dual-command cycles.
