How many actual hours are neededat the work center if the efficiency is 110% and the utilization is 85%?A production line contains two stations in series. A total of 10000 good parts are to be manufactured during 300 working days in a year and 8 hours per day (60 min peer hour). The following information are given. For station 1: Scrap rate is 5%, standard time per part is 20 minuts, Efficiency is 85% and machine reliability is 90%. For station 2: Scrap rate is 4%, standard time per part is 30 minuts, Efficiency is 80% and machine reliability is 95%. How many machines would be required at each station?

- Three departments- milling (M), drilling (D), andsawing (S)- are assigned to three work areas in Victor Berardis'smachine shop in Kent, Ohio. The number of workpieces movedper day and the distances between the centers of the work areas,in feet, follow. Pieces Moved between Work Areas Each Day lt costs $2 to move I workpiece I foot.What is the cost?SITUATION: A company is about to begin production of a new product. The manager of the department that will produce one of the components for the product wants to know how often the machine used to produce the item will be available for other work. The machine will produce the item at a rate of 200 units a day. Eighty units will be used daily in assembling the final product. Assembly will take place five days a week, 50 weeks a year. The manager estimates that it will take almost a full day to get the machine ready for a production run, at the cost of $300. Inventory holding costs will be $10 a year. QUESTION: Suppose the manager decides to increase the run size of the new product. How many additional units would be needed just to accommodate the other job? How much will that increase the total annual cost?A small formwork subcontractor is awarded to erect formwork. It has been estimated 75labor-days. The dailly production rate of one worker is 25 m2. Calculate the number of days required to complete the job if the subcontractor has 5 crew, each crew made up of three workers.
- a. what is the bottleneck of this process? b. what is the hourly capacity of the process?You've just been assigned the job of setting up an electric fan assembly line with the following tasks and precedence relationships The assemtly line wil be nunning 8 hours per day and 5 days per week, The demand forast is 600 Items per week. Your goal is to minimie the numbor of workstations necesary to complete enough units to satisfy the demand forecast. What is the takt time (in minutes) needed to produce the required number of units? (Integer Answer, do not put anything other than numbers.) What is the theoretical minimum number of workstations that you will need (apply the round-up rule)? (Integer Answer, do not put anything other than numbers.)14. A production line is to be designed to assemble a product. The assembly of this product requires three tasks, one of which requires 0.3 minutes to complete, one of which requires 1.4 minutes to complete , and one of which requires 0.7 minutes to complete. If this production line has three workstations and a cycle time of 1.5 minutes , what is its efficiency ?
