= 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…

The three-station work cell at Pullman Mfg., Inc. is illustrated in the figure below. It has two machines at station 1 in parallel (i.e., the product needs to go through only one of the two machines before proceeding to station 2). 30 min/unit Station 1 Machine A Station 2 Station 3 Station 1 3 min/unit 2 min/unit Machine B 30 min/unit a) The throughput time is minutes (enter your response as a whole number). b) The bottleneck time of this work cell is minutes per unit (enter your response as a whole number). c) is the bottleneck station d) If the firm operates 8 hours per day, 6 days per week, the weekly capacity of this work cell is units (enter your response as a whole number).
Three machines are used in a group-technology cell to process a family of five parts. Thetable below lists production quantities (Qj), production times (Tpij), and machine fractionsfor each family member (fij). Part E requires a changeover time of 5 min on each machine soit is produced in batches of 5 parts. Nonoperation times (Tno) are the same for all parts andmachines: 25 min per machine. Determine (a) average hourly production rate for the cell,(b) utilization of each machine and average utilization of the cell, (c) manufacturing leadtime, and (d) work-in-process. A spreadsheet calculator is recommended for this problem
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.
The gross requirements for item Z are specified for the beginning of weeks 1 through 8 in the table that follows. Gross Requirements for Item Z 1 2 3 6 7 8 Week 4 Gross Requirement 180 90 180 0 360 0 90 90 The lead time is 2 weeks. The current on hand inventory, at the beginning of week 1 is 360 units. If the order cost is $540 per order and the inventory cost is $3 per unit per period, and the order quantity is the computed part period (or a multiple of the computed part period) when it is necessary to place an order, what is the total cost for the 8 week period? Report as a whole number with no commas. Answer: The correct answer is: 4590
Consider the following tasks that must be assigned to four workers on a conveyor-paced assembly line (i.e., a machine-paced line flow). Each worker must perform at least one task. There exists unlimited demand unless stated otherwise. Time to Complete Task (seconds): Task 1: 30 Task 2: 25 Task 3: 15 Task 4: 20 Task 5: 15 Task 6: 20 Task 7: 50 Task 8: 15 Task 9: 20 Task 10: 25 Task 11: 15 Task 12: 20 The current conveyor-paced assembly-line configuration assigns the workers in the following way: • Worker 1: Tasks 1, 2, 3 • Worker 2: Tasks 4, 5, 6 • Worker 3: Tasks 7, 8, 9 • Worker 4: Tasks 10, 11, 12 What is the capacity of the current line (in units per hour)?
8086 Microprocessor lab. | 9 Discussion: Two word - wide unsigned integers are stored at the memory addresses OA00 H and OA02 H respectively, Write an instruction sequence that computes and stores their sum, difference, product, and quotient then Store these results at consecutive memory locations starting at address 0A10 H in memory. To obtain the difference, subtract the integer at OA02 H from the integer at OA00 H. For the division, divide the integer at OA00H by the integer at OA02 H. Use register indirect relative addressing mode to store the various result.
