Exam 7: Constraint Management

Figure 7.1 -Use the information in Figure 7.1.If each task has a work time of one minute and there are 8 hours in a day,what is the task assignment at the first station if 160 units should be produced each day?

Instead of producing products with the highest profit margins,operations managers should focus on the ________ generated at the ________ .

To generate the maximum output,the cycle time should be set as the longest elemental task time.

Line balancing strives to create workstations so that the capacity utilization for the bottleneck is much higher than for the other workstations in the line.

According to the Theory of Constraints,the four operational measures of capacity include all of the following EXCEPT:

The fifth step in Theory of Constraints application,"do not let inertia set in," means that the analyst should:

Table 7.2 The figure above shows the process for paying tuition at a major university.Students are provided their bill for the next term for review,then routed to different tables for questions to be answered before finally paying their tuition at E.The numbers in parentheses are the time in minutes for each step of the process. -Use the information in Table 7.2.What is the capacity for the A-B-C-E process route?

What is a Drum-Buffer-Rope system for planning and control?

The process with the least capacity is called a bottleneck if its output is still greater than the market demand.

According to the Theory of Constraints,all the money invested in a system in purchasing things that it intends to sell is ________.

Table 7.7 A company makes four products that have the following characteristics: Product A sells for $75 but needs $20 of materials and $20 of labor to produce;Product B sells for $90 but needs $45 of materials and $20 of labor to produce;Product C sells for $110 but needs $50 of materials and $30 of labor to produce;Product D sells for $135 but needs $75 of materials and $40 of labor to produce.The processing requirements for each product on each of the four machines are shown in the table. Work centers W,X,Y,and Z are available for 40 hours per week and have no setup time when switching between products.Market demand is 50 As,60 Bs,70 Cs,and 80 Ds per week.In the questions that follow,the traditional method refers to maximizing the contribution margin per unit for each product,and the bottleneck method refers to maximizing the contribution margin per minute at the bottleneck for each product. -Use the information in Table 7.7.Using the bottleneck method,which product should be scheduled first?

________ is the total time taken from the start to the finish of a process.

Which one of the following statements about line balancing is best?

A bottleneck is an operation that has the lowest effective capacity of any operation in the process.

The balance delay is the amount by which efficiency falls short of 100 percent.

Table 7.11 The Pennsylvania Appliance Company is installing an assembly line to produce vacuum cleaners,and you,as an operations manager,are responsible for balancing the line.The work elements to be performed are listed,along with their times and immediate predecessors. -Use the information in Table 7.11.The company is planning to operate 2 shifts per day 8 hours per shift.If the desired output rate of the line is 480 units per day,what is the theoretical minimum number of stations (TM)for the line? How many workstations are needed for the most efficient balance possible given these circumstances?
