A rider lawn mower is produced on a manual assembly line. Work content time=49.5 min. The line has 25 workstations with a manning level = 1.2. Available shift time per day = 8 hr, but equipment downtime during the shift reduces actual production time to 7.5 hr on average. This results in an average daily production of 244 units/day. Repositioning time per worker = 5% of cycle time. Determine (a) line efficiency, (b) balancing efficiency, and (c) repositioning time.

9. A new product is to be assembled on a 100% manual assembly line. The line is designed to produce 120,000 units/yr. Work content time for the product is 39.5 min. The assembly line will operate 50 wklyr, 5 shifts/wk, 8 hr/shift. Expected line efficiency is 96%. There will be one worker per station. Determine (a) average hourly production rate, (b) cycle time, and (c) ideal minimum number of workstations.(6 pts)

A manual assembly line is to be designed to make a small consumer product. The work elements, their times, and precedence constraints are given in the table below. The workers will operate the line for 400 min per day and must produce 300 products per day. A mechanized belt, moving at a speed of 1.25 m/min, will transport the products between stations. Because of the variability in the time required to perform the assembly operations, it has been determined that...

4.22 The table below lists the work elements in minutes to be performed on assembly line with precedence requirements. Annual demand is 60000 units. The line will operate on shift (2000 hr/yr). Line efficiency is expected 95% and repositioning time is 6 sec. The table below defines the precedence relationships and element times for a new model toy. (a) Construct the precedence diagram for this job. (b) If the ideal cycle time = 1.1 min. repositioning time = 0.1 min,...
