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 each. Does the system achieve the specified flow rate? If so, what are appropriate values for the number of carriers and the spacing between carriers?

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...

A lift station is to be designed to handle wastewater flows
ranging from 400 gpm to 1500 gpm. The influent sewer invert
elevation is 600 ft. The discharge line is 2,000 ft long with a
high point elevation of 625 ft. A wet well diameter of 10 ft is to
be used. Recommend the pump capacity, the number of pumps, and the
TDH.
Assume the following:

Suppose a workstation receives parts automatically from a
conveyor. An accumulation line has been provided at the workstation
and has a storage capacity for 5 parts (N=6). Parts arrive randomly
at the switching junction for the workstation; if the accumulation
line is full, parts are diverted to another workstation. Parts
arrive at a Poisson rate of 1 per minute; service time at the
workstation is exponentially distributed with a mean of 45
seconds.
a. What is the rate at which...
