Ás an engineer, suppose you are directed to design a pumping system to safely discharge a toxic industrial waste into a municipal reservoir. The concentrated wastewater from the plant will be mixed with freshwater from the lake, and this mixture is to be pumped into the center of the lake. You realize that the more water you mix with the waste, the more dilute it will be and thus the smaller the impact on the fish in the lake. On the other hand, the more the oou use, the more it costs in electricity for pumping. Your objective is to determine the optimum amount of water to pump so the overall cost is a minimum.

Operations Management

Sometimes job design has to be modified to adapt to emergent technologies or product redesign. How can OD interventions assist in this scenario?

Explain the batch flow and continuous flow process in manufacturing

Weldex Industries begins to manufacture a newly designed, small, spot welding machine. The labour hours required for making the second and third units are 28.6 and 28.2 hours respectively. The labour hours required to manufacture the 50th unit are Select one: 25.6 hours 23.8 hours 27.9 hours 29.3 hours

11:33 20. A worker will work for 48 hours per week for 6 days. If the standard time is 12.58 minutes compute the production standard per day. Just write the answer, no need to write the units Your answer Your answer 21. if standard time in for present method is * 15.25 minutes per unit, standard time for improved method is 9.10 minutes per unit. Assume worker will work for 40 hours per week for 5 days. compute the production standard of present method 22. Compute the production standard of improve method Your answer AA LTE 67 docs.google.com 8 *

A widget assembly process was timed for 75 cycles and had an average of 1.5 minutes per piece. The performance rating was 95%, and workday allowances are 10 percent. Determine the following: a) Observed time b) Normal time c) Standard time d) How might this information be used?

A) Which step in this process is the bottleneck? =30 min for tan leather B) How many briefcases are processed at the bottleneck workstation per hour?=60/30=2 briefcases per hr C) What is the throughput time of the overall process?=30+15+10+10+10 Throughput = 75 minutes   given the above information please answer qestions 1-3 below.  If the manufacturing facility operates 8 hours per day, 250 days a year, what is the annual capacity of this manufacturing process.  Assume the company decides to hire additional workers in order to duplicate the bottleneck step identified in part a so that there are 3 of these workstations instead of 1. Redraw the diagram showing the flow of the revised process.  Answer parts a through d again based on the new process created in part e?

Ques. Which one of the following refers to the length of time needed to complete a job? (a) Work sampling methods (b) Work measurement (c) Job design (d) Methods analysis

1.The standard time fixed for the worker is 20 hours to complete a job. If a worker completes the job in 16 hours and the wage for one hour is 4 Rials, Calculate incentive as per Halsey plan and Rowan plan and find out which is beneficial to employer
