An FMS consists of three stations plus a load/unload station. Station 1 loads and unloads parts using two servers (material handling workers). Station 2 performs horizontal milling operations with two servers (identical CNC horizontal milling machines). Station 3 performs vertical milling operations with three servers (identical CNC vertical milling machines). Station 4 performs drilling operations with two servers (identical drill presses). The machines are connected by a part handling system that has two work carriers and a mean transport time = 3.5 min. The FMS produces four parts, A, B, C, and D, whose part mix fractions and process routings are presented in the table below. The operation frequency is fijk = 1.0 for all operations. Determine (a) maximum production rate of the FMS, (b) utilization of each machine in this system, and (c) average utilisation of the system U s .

Three balanced three-phase loads are connected in parallel. Load 1 is Y-connected with an impedance of 420+300i Ω/ϕ ; load 2 is Δ-connected with an impedance of 2400-1780i Ω/ϕ ; and load 3 is 170.1+2201i kVA . The loads are fed from a distribution line with an impedance of 2+17i Ω/ϕ . The magnitude of the line-to-neutral voltage at the load end of the line is 23√3 kV. Part A: Calculate the total complex power at the sending end of...

Three balanced 3-phase loads are connected in parallel. Load 1 is Y-connected with an impedance of 400 + j300 ? per phase, load 2 is ?-connected with an impedance of 2400 – j1800 ? per phase, and load 3 is absorbing 172.8 + j2203.2 kVA. The loads are fed from a set of distribution lines with an impedance of 2 + j16 ? per line. The magnitude of the line-to-neutral voltage at the load end of the line is 24?3...

A closed loop overhead conveyor must be designed to deliver parts from a load station to an unload station. The specified flow rate of parts between the two stations is 320 parts/hr. The conveyor has carriers spaced at a center-to-center distance that is to be determined. Each carrier holds one part. Forward and return loops are each 75 m. Conveyor speed is 0.6 m/s. Minimum feasible times to load and unload parts at the respective stations is 0.16 min for...

A car wash has two stations, 1 and 2. The service time at station 1 is exponentially distributed with parameter λ1, and the service time at station 2 is exponentially distributed with parameter λ2.When a car arrives at the car wash, it begins service at station 1, provided station 1 is free; otherwise, the car waits until station 1 is available. Upon completing service at station 1, the car then proceeds to station 2, provided station 2 is free; otherwise,...

Consider a production line with five stations. Station 1 can produce a unit in 9 minutes. Station 2 can produce a unit in 10 minutes. Station 3 has two identical machines, each of which can process a unit in 12 minutes (each unit only needs to be processed on one of the two machines. Station 4 can produce a unit in 5 minutes. Station 5 can produce a unit in 8 minutes. Which station is the bottleneck station?

A space station consists of three modules, connected to form an equilateral triangle of side length 82.0 m. Suppose 100 people, with an average mass of 75.0 kg each, live in each capsule and the mass of the modules is negligible compared to the mass of the people. If everyone went to the top left module for a parade what would be the change in position of (a) the center of mass of the station and (b) top left module,...

There are a total of 10 test stations. When a circuit board fails, the test station will automatically record the lifetime for the failed board and then immediately switch to a replacement board. The test was stopped at 1200 hours. At that time, 19 circuit boards had failed and there was an operating circuit board in every station. Assuming the boards have exponentially-distributed lifetimes, estimate the mean lifetime for this type of board.
