27. You have the following compound machine. For S and ins a. What is the ideal mechanical advantage of this system? The inclined plane dimensions are 7.2 meters length and 1.8 meters height. What effort force is required to move the 600N create? In practice, you need to supply an effort force of 75 N to lift the crate. What is the efficiency? C. How could you redesign this compound d. machine so that the effort force needed was 50 N in practice? Assume the efficiency is your response from part C no matter what changes you make. Be specific with the changes you propose (if you add pulleys state how many, if you change the inclined plane dimensions state the new dimensions, etc.).
Q4: The Dynaco Manufacturing Company produces a particular product in an assembly line operation. One of the machines on the line is a drill press that has a single assembly line feeding into it. A partially completed unit arrives at the press to be worked on every 7.5 minutes, on average. The machine operator can process an average of 10 parts per hour. a: Determine the average number of parts waiting b: the percentage of time the operator is working, and be worked on, c: the percentage of time the machine is idle. 1 d: The management of Dynaco Manufacturing Company likes to have its operators working 90% of the time. What must the assembly line arrival rate be for the operators to be as busy as management would like? 63

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.

= 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. Determine the throughput…
