Exam 5: Constraint Management

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

________ is a planning and control system that regulates the flow of work-in-process materials at the bottleneck or the capacity constrained resource in a productive system.

Table 5.7 The Terminal Company is attempting to balance its assembly line of high-voltage electrical connectors.The desired output for the line is 50 connectors per hour,and the information on the work elements for this assembly line is as follows. -Use the information from Table 5.7 and the most efficient line balance possible.What work elements are included in the first station?

Table 5.1 A company makes four products that have the following characteristics: Product A sells for $50 but needs $10 of materials and $15 of labor to produce;Product B sells for $75 but needs $30 of materials and $15 of labor to produce;Product C sells for $100 but needs $50 of materials and $30 of labor to produce;Product D sells for $150 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 for each product is 80 units 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 5.1.Using the traditional method,in what sequence should products be scheduled for production?

Figure 5.2 The figure above shows the process for customers arriving at Pierre's Spa and Salon.After signing in,customers are routed to different locations in the Spa for the two different services provided.The numbers in parentheses are the time in minutes for each step of the process. -Use the information in Figure 5.2.What is the throughput time for the A-B-E-F-G-H routing?

Figure 5.2 The figure above shows the process for customers arriving at Pierre's Spa and Salon.After signing in,customers are routed to different locations in the Spa for the two different services provided.The numbers in parentheses are the time in minutes for each step of the process. -Use the information in Figure 5.2.What is the process bottleneck?

Figure 5.4 -Use the information in Figure 5.4.If each task has a work time of one minute and there are 8 hours in a day,what is the minimum number of stations if 240 units should be produced each day?

Table 5.2 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 5.2.Using the bottleneck method,which product should be scheduled first?

Which statement about process batches is BEST?

Balance the assembly line using the following task information contained in the table.The desired output is 360 units per day.Available production time per day is 480 minutes.What is the efficiency for the balanced assembly line?

A(n)________ is an operation that has the lowest effective capacity of any operation in the process,and thus limits the system's output.

Table 5.1 A company makes four products that have the following characteristics: Product A sells for $50 but needs $10 of materials and $15 of labor to produce;Product B sells for $75 but needs $30 of materials and $15 of labor to produce;Product C sells for $100 but needs $50 of materials and $30 of labor to produce;Product D sells for $150 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 for each product is 80 units 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 5.1.Using the bottleneck method,what is the profit if the company manufactures the optimal product mix (consider variable costs only-overhead is not included in this profit calculation)?

There are three consecutive steps in a customer service process.The first two steps are each capable of serving 25 customers per hour while the third step can process only 20 customers per hour.Which of the following statements regarding this system is TRUE?

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

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

The second step in Theory of Constraints application,"exploit the bottleneck(s)," means that the analyst should:

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