An emergency stop system is to be designed for a certain automatic production machine. A single "start" button is used to turn on the power to the machine at the beginning of the day. In addition, there are three "stop" buttons located at different locations around the machine, any one of which can be pressed to immediately turn off power to the machine. (a) Write the truth table for this system. (b) Write the Boolean logic expression for the system. (c) Construct the logic network diagram for the system. (d) Construct the ladder logic diagram for the system

An M/M/4 system has an arrival rate of 15 customers per hour. Each server has a service rate of 9 customers per hour. a. What is the utilization factor for this system? (Round your answer to 3 decimal places.) Utilization factor b. If all servers are kept busy, how many services will be completed per hour? (Round your answer to the nearest whole number) Services completed per hour

Hartley Electronics, Inc., in Nashville, producesshort runs of custom airwave scanners for the defense industry.The owner, Janet Hartley, has asked you to reduce inventory byintroducing a kanban system. After several hours of analysis, youdevelop the following data for scanner connectors used in onework cell. How many kanbans do you need for this connector?Daily demand 1,000 connectorsLead time 2 daysSafety stock 12 dayKanban size 500 connectors

Please don't use AI becuase it is not correct.

DISCUSS THE STEP-BY-STEP PROCESS OF HOW TO COME UP WITH A SOLUTION.   *Preferably if you typed the answer Thumbs up guaranteed If you discuss the steps. Thankyou!

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?

The analyst in the Dorben Company wishes to assign a number of like facilities to an operator based on minimizing the cost per unit of output. A detailed study of the facilities revealed the following:   Loading machine standard time = 0.30 minutes Unloading machine standard time = 0.25 minutes Walk time between two machines = 0.09 minutes Operator rate = $12.00 per hour Machine rate (both idle and working) = $18.00 per hour Machine cycle time = 1.55 minutes TEC = The Expected Cost a) With your initial estimation, how many machines can be serviced exactly?(please keep a non-integer with three decimal places) b) How much is your TEC per piece if the operator has idle time? (please keep three decimal places) c)How much is your TEC per piece if the machine has idle time?  (please keep three decimal places) d) How many of these machines should be assigned to each operator?(please write down a numerical number)

its a true false question. please answer its all. thank you

System Specification The aim of task 2 is to design a simulated obstacle detection sensor system for a mobile robot platform. You should assume your chosen sensors will be placed on a small mobile robot platform as designed in task 1. The sensor system must be able to detect objects within the range of 0mm to 1000mm and have a field of vision of 90 degrees (see diagram below). You may need to use multiple sensors to achieve the desired specification. Robot platform H 0-1000mm range 90° sensor view Example object

The table below lists the time estimates and immediate predecessor(s) for each activity in a product marketing project that is to be scheduled using CPM. Similar projects for other products have been accomplished in the past, so the activity times are fairly certain. (a) Draw the CPM network diagram for the project, labeling all activities and times. (b) Perform a forward pass and backward pass through the network to determine the critical path, the expected duration of the project, and the slack time for each activity. Activity 1 3 4 5 7 8 9 Activity time (days) 1 3 7 5 6 9. 4 Immediate predecessor 1 1 1 2 3,4 5,6 4 7,8 Solve the preceding problem but use an estimated activity time of 4 days instead of 2 days for activity 6. 6. 2. 2.
