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.

Basic Manufacturing Process with 2 Job Types + Inspection Time between job arrivals at a machining station is exponentially distributed with mean 4.4 minutes. There are 2 types of jobs to be processed 30% of which is Type 1 and, 70% are of Type 2. Processing times are exponentially distributed. Mean processing time for Type 1 is 4.8 minutes, for Type 2 it is 2.5 minutes. After the job is processed, they go through an inspection process with one single inspector and an inspection time with triangular distribution (1,2,3.5). Inspector decides whether the part is good enough, scrap or should be reworked. 80% of the parts produced is good, 10 % is scrap and the rest needs rework. Rework is done by the same manufacturing machine. The priority among the parts will be Part1 first, part2 second and reworks of both type comes later. Rework time is normally distributed with mean 2 minutes and 0,2 std dev. Simulate the system for one 8-hour day.
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
At a certain CNC machine, jobs arrive according to Poisson's distribution at a rate of 25 jobs per hour. The worker at this machine loads 5 jobs at a time and unloads them after 10 mins. The loading and unloading follows an exponential distribution. The expected queue length is.
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)?
Inventory Control A company anticipates there will be a demand for 20,000 copies of a certain book during the next year/. It costs the company $0.50 to store a book for 1 year. Each time it must print additional books, it costs $200 to set up the equipment. NOTE: We assume that the demand is uniform. Let • x= number of books printed during each printing run ● y= = number of printing runs
8. Why do experiments have a control group as part of the design? to see if the treatment (changing the independent variable) has any effect to use as a backup, In case the experiment fails the first time O to help the scientists determine which varlable is the dependent variable to minimize the number of varlables in the experiment
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
Draw the block diagram of a Temperature measurement system .Also identify the names of the functional elements used in the measurement system.
A. A student establishes the time constant of a temperature sensor by first holding it immersed in hot water and then suddenly removing it and holding it immersed in cold water. Several other students perform the same test with similar sensors. Overall, their results are inconsistent, with estimated time constants differing by as much as a factor of 1.2. Offer suggestions about why this might happen. Hint: Try this yourself and think about control of test conditions. B. Which would you expect to be better suited to measure a time-dependent temperature, a thermal sensor (e.g., a thermocouple) having a small diameter spherical bead or one having a large diameter spherical bead? Why?
