There is an upstream Picking department that feeds two downstream
Packing departments: Pack Singles and Pack Multis. Those Packing departments feed to a Shipping department that loads the outgoing trucks. 40% of your Pick volume goes to Pack Singles and has a packing rate of 104 units per labor hour (uph). 60% of the Pick volume goes to Pack Multis and has a pack rate of 215 units per labor hour. Your pickers pick both Single and Multi items throughout the day at an overall average rate of 114 units per labor hour. All units that are packed in both processes go through the Ship process at a rate of 570 units per hour. You have 102 people today for all 4 departments and you absolutely must pack 47,880 units in Pack Multis Items to meet a customer promise metric. How do you allocate labor to balance the flow in your department if you work a 10 hour shift? Do not assume breaks or lunches in your answer. Redirect 1: You now need to process all of the Pack Singles Volume in the first 5…
A recurring maintenance job in a factory is being done by a three-man crew. Due to the nature of the job and space limitations, it was observed that two of the men were idle 37% of the time; one of the men was also idle an additional of the time, and at any given time only one man was required. The men were each paid P24.00 per hour. Each time the job was performed a set of tools and equipment with a value equivalent to P36.00 per hour was used. If the three-men crew could complete the work in 5 hours, which crew size would be the most economical
During an eight-hour shift, 750 non-defective parts are desired as a result of a manufacturing operation. The default operation time is 15 minutes. As the operators of machine are inexperienced, the actual time they take to perform the operation is 20 minutes, and, on average, a fifth of the parts that start to be manufactured are lost. Assuming that each one of the machines used in this operation will not be available for one hour in each shift, determine the number of machines needed.

- A company makes two products (A and B). Each product requires time on two machines 1 and 2. the specifications for each product are as follows Product A Product B Processing time on machine 1 (hrs/unit) Processing time on machine 2 (hrs/unit) Material and labor cost (Sh./ unit) Selling price (Sh./ unit) Maximum possible sale (units) 2 1 2 14 15 16 18 130 150 The amount of time available on machine 1 is 360 hrs and on machine 2 is 260 hrs. Using simplex method determine the number of product A and B, which should be sold in order to maximize total contribution for the company.arrow_forwardCompany ZWZ manufactures three products in a serial system; Product XA is manufactured in Stage 1, Product XB in Stage 2, and XC in Stage 3. Product XB has a sales potential in the market; hence, some of it can be sold at the end of Stage 2, and the remaining can be moved to Stage 3. The third stage produces Product XC, and then delivers it to customers. Two units of Product XA produced in Stage 1 are required for each unit of Product XB in Stage 2. In addition, four units of Product XB produced in Stage 2 are required for each unit of Product XC in Stage 3. Stage 1 can only use regular time; however, Stage 2 has the options of using regular time and overtime in manufacturing. On the other hand, Stage 3 has only one alternative, which is subcontracting. The pertinent data are provided below: Stage 2 Stage 1 11 No overtime No subcontracting No sales 0.07 Unit regular time cost (TL) Unit overtime cost (TL) Unit subcontracting cost (TL) Unit selling price (TL) Unit processing time (hrs)…arrow_forwardRollmore, a non-union manufacturing company decides it needs input on improving its work processes and procedures and decides to create employee committees to provide general feedback about things such as work rules and organizational policies and practices in hopes of improving efficiency.

Each specialist has about 5 administrative employees who help with coding, billing, customer service, and other administrative tasks. You supervise all administrative employees. For two months you have noticed that a series of conflicts have arisen between the employees you supervise, which you must address promptly to avoid escalation. These are the conflicts that have been identified: A new position has been opened to supervise night operations and two of the employees have requested it. However, both have resorted to demonstrating that the other does not have the capabilities to rise to the position. These interpersonal differences have resulted in a tense work environment.It has been rumored that one of the medical specialists is going to retire, so it is possible that he will put the five administrative employees…arrow_forwardNewTel is a telephone company with a policy of filling positions internally through promotions, rather than hiring from outside. Until recently, the company had a strong engineering focus and tended to promote people to senior executive positions from the engineering areas. Consequently, almost all of the company's 14 senior executives joined the company over 20 years ago as junior engineers. There is increasing pressure on NewTel to become more market and service oriented. As a result, four people were hired last year from firms to fill new senior executive positions in marketing and service departments. The external hires were necessary because current employees were not sufficiently qualified. Now, there are signs of tension among senior executives, particularly during budget deliberations where there is limited discretionary spending on new corporate activities. The four new hires have been thwarted in their attempts to have the company invest more in marketing and customer…arrow_forwardAn industrial engineer has designed two alternative methods for accomplishing a production job. Both methods involve the acquisition of the same working place and other capital equipment to be used for this job only. Method A calls for a crew consisting of three men each costing Php30/hr. This method will result in the production of 10 units per hour of which two will be reject. Method B calls for a crew of two men each costing Php35/hr and should result in the production of eight units per hour of which one will be reject. The cost of the direct material lost in each reject is Php20. If a certain total number of units is to be produced find which method is economical?arrow_forward

Meritor, a company that makes muffler assemblies for the automotive industry, is committed to the use of kanban to pull material through its manufacturing cells. Meritor has designed each cell to fabricate a specific family of muffler products. Fabricating a muffler assembly involves cutting and bending pieces of pipe that are welded to a muffler and a catalytic converter. The mufflers and catalytic converters are pulled into the cell based on current demand. The catalytic converters are made in a specialized cell. Catalytic converters are made in batches of 15 units and are moved in special hand carts to the fabrication cells. The catalytic converter cell is designed so that different types of catalytic converters can be made with virtually no setup loss. Meritor hires a team of consultants. The consultants suggest a partial robotic automation, as well as an increase in safety stock to 8.5 percent. Meritor implements these suggestions. The result is an increase in…arrow_forwardTwo vital stages in a production process are assembly I and assembly II.
