| The fifth of the five focusing steps in the theory of constraints states that once the constraint is no longer, you find the new constraint and repeat the five focusing steps again. | Repeat the five focusing steps again |
| In the theory of constraints planning and control system, which of the following techniques facilitates the capacity control function? | Buffer management |
| A consultant wants to understand the general flow of parts and products from raw materials to finished products before implementing the theory of constraints. Which of the following analyses should be performed to accomplish this task? | Vati.. VATI is a procedure for determining the general flow of parts and products from raw materials to finished products (logical product structure). Once the general parts flow is determined, the system control points (gating operations, convergent poi |
| Which of the following concepts is based on the fact that every operation producing a product or service is a series of linked processes, has a specific capacity to produce product, and that one process limits the throughput of the entire operation? | Theory of constraints The Theory of Constraints is a holistic management philosophy that is based on the principle that complex systems exhibit inherent simplicity. Even a very complex system comprising thousands of people and pieces of equipment can h |
| A scheduling technique that builds a schedule by proceeding sequentially from the initial period to the final period while observing capacity limits is known as | Finite forward scheduling. Finite forward scheduling is an equipment scheduling technique that builds a schedule by proceeding sequentially from the initial period to the final period while observing capacity limits. |
| The tool that uses mathematical algorithms or logic to perform optimization or simulation on finite capacity scheduling is | Advanced Planning and Scheduling APS describes any computer program that uses advanced mathematical algorithms or logic to perform optimization or simulation on finite capacity scheduling, sourcing, capital planning, resource planning, forecasting, dem |
| The selecting and sequencing of available jobs to be run at individual workstations and the assignment of those jobs to workers is called | Dispatching Dispatching refers to the selecting and sequencing of available jobs to be run at individual workstations and the assignment of those jobs to workers. |
| A manufacturer has set production rates of copper wire at 50m every hour. Materials are fed into the system to meet that pre-arranged rate. Of what type of control system is this an example? | Flow control Flow control is a specific production control system that is based primarily on setting production rates and feeding work into production to meet these pre-planned rates. |
| A facility, function, department, or resource whose capacity is less than the demand placed upon it is called a | Bottleneck A bottleneck is a facility, function, department, or resource whose capacity is less than the demand placed upon it. For example, a bottleneck machine or work center exists where jobs are processed at a slower rate than they are demanded. |
| Which of the following statements regarding scheduling bottlenecks is true? | A bottleneck must be fed at a rate equal to its capacity A bottleneck must be fed at a rate equal to its capacity so that the time buffer remains constant. |
| A scheduling system sends part of a lot on to the next stage in processing before it has completed working on all materials it received. What is the name given to this useful expediting tool? | Overlapped scheduling Overlapping occurs when the completed portion of an order at one work center is processed at one or more succeeding work centers before the pieces left behind are finished at the preceding work centers. |
| The drum in the drum-buffer-rope method represents the pace | of the constraint in the process. In the theory of constraints, the drum represents the pace of the constraint, which sets the production pace for the entire system. |
| The way to avoid a constraint downstream is by: | establishing a space buffer A space buffer is located immediately downstream of the constraint and protects against downtime downstream from the constraint. The size allowed should be enough to protect against any reasonably foreseeable downtime. Usuall |
| In the theory of constraints (TOC) philosophy, the term "the weakest link" is used to describe: | the resource with the least throughput in the system In every system there is one weakest link - the constraint that limits the system from achieving higher levels of its goal |
| In every system there is one weakest link - the constraint that limits the system from achieving higher levels of its goal | Subordinate all else to the constraint to the system. Once a process constraint has been identified, WIP is reduced by making all loads equal to the allowable capacity found at the constrained process. Any load released to the manufacturing floor that |
| An element of time or material that can be maintained at the constraint, convergent points, divergent points, and shipping points is | Buffer. In the theory of constraints, buffers can be time or material and support throughput and/or due date performance. Buffers can be maintained at the constraint, convergent points (with a constraint part), divergent points, and shipping points. |
| Scheduling a constraint involves | Finding methods to maximize utilization of the constraint. The second of the five focusing steps in the theory of constraints, deciding how to exploit the constraint to the system, is key. The other answers are not directly related to scheduling a const |
| In theory of constraints (TOC), which of the following terms refers to materials awaiting further processing? | Buffer A process buffer consists of raw materials, components, or subassemblies that are waiting to be used in production when the demand pull occurs. There are no queues in a TOC system; production is initiated by the drum and not by pre-released orders |
| Which of the following outcomes will occur if work is scheduled at a higher rate of production than is actually produced? | work-in-process will increase If more work is scheduled at a workstation than can be completed, the amount of work-in-process will increase |
| Pick lists are most likely to exclude: | floor stock materials issued to the department Floor stock items are already issued; the other responses would all need to be picked and issued to production. |
| The drum in the drum-buffer-rope scheduling process serves which of the following functions? | It is used to create the master production schedule. The drum of the system refers to the 'drumbeat' or pace of production. It represents the master schedule for the operation, which is focused around the pact of throughout as defined by the constrain |
| A shop order packet contains the authorization for a particular item, or number of items to be made. Which of the following authorizations may also need to be issued as part of the order packet? | Pick list The shop order packet will include what the shop floor needs to successfully produce the items. |
| In the theory of constraints (TOC) philosophy, the term the weakest link is used to describe: | the resource with the least throughput in the system. In every system there is one weakest link - the constraint that limits the system from achieving higher levels of its goal. |
| Input/output control is a technique for monitoring the | Capacity requirements plan Input/output control is a technique in which actual input and output of a work center is compared with the planned input and output developed by CRP. |
| Critical ratio and queue ratio are used for | Priority planning Critical ratio is a dispatching rule that calculates a priority index number by dividing the time to due date remaining by the expected elapsed time to finish the job. Queue ratio is the ratio of the hours of slack within the job to th |
| First Come, First Served | With FCFS, jobs are done in the order in which they are received, irrespective of due dates and processing times. This dispatching rule works well if schedules are well-designed and stable |
| Drum-buffer-rope is the term for | Scheduling and managing operations that have an internal constraint or capacity-constrained resource. |
