A flow-line mass production operation consists of six manual workstations. Work units are moved synchronously and automatically between stations, with a transfer time of 10 secs. The manual processing operations performed at the six stations take 45 sec, 50 sec, 40 sec, 42 sec, 30 sec, and 55 sec, respectively. Determine (a) cycle time for the line, (b) time to process one work until through the six workstations, (c) average production rate, and (d) time to produce 20,000 units.
A machine with rational sections and subsystems is better than one that doesn't have either.
Who is credited with the creation of the first mechanical computer, the Difference Engine?

- 4) A factory manufactures chairs, tables and bookcases each requiring the use of three operations: Cutting, Assembly, and Finishing. The first operation can be used at most 600 hours; the second at most 500 hours; and the third at most 300 hours. A chair requires 1 hour of cutting, 1 hour of assembly, and 1 hour of finishing; a table needs 1 hour of cutting, 2 hours of assembly, and 1 hour of finishing; and a bookcase requires 3 hours of cutting, 1 hour of assembly, and 1 hour of finishing.

Product A needs 1 working hour in the first phase, and 4 working hours in the second phase, while Product B needs 2 working hours in the first phase, and 3 hours of work in the second stage. If you know that the profit per unit of product A is $60, and the profit per unit of product B is $50. The available weekly working hours in the first stage are 40 hours, and in the second stage are 120 hours. Required: Building a mathematical model that maximizes the company's profitsarrow_forward
