Which of the following statement is(are) true in ROP analysis?

All statements are true

In Theory of Constraints, which of the following is represented by "drum"?

Bottleneck resource

The Theory of Constraints (TOC) approach is also referred to as

Drum - Buffer - Rope

The prime objective of PAC is:

Executing MPC plans

As the service level increases, the probability of not running out of stock during a cycle decreases.

False

Dispatching involves the use of logic that guides the prioritizing of jobs at a workstation. These rules are referred to as lot-sizing rules.

False

In MRP, the only source of uncertainty is supply.

False

In a TOC system, inventory buffers before bottleneck resources are eliminated

False

In a single machine job shop, the makespan depends on the rule used for scheduling.

False

Johnson's rule when applied in a two-machine case will provide minimum average lateness.

False

PAC stands for Process Activity Control

False

The EOQ is based on the assumption of lumpy demand,

False

The use of the lot-for-lot procedure tends to increase the lumpiness of the gross requirements of items further down in the BOM.

False

Which of the following three strategies can be useful in reducing MRP system nervousness? I- Using Time fences II- Using Firm Planned Orders III- Careful use of Lot-Sizing procedures

I, II, III

Which of the following statement(s) is (are) TRUE?

In a one machine system, the EDD rule for sequencing the order of jobs will result in minimizing average lateness

Which of the below lot-sizing procedures provide an optimal solution in MRP lot-sizing?

KBB

Which one of the following lot-sizing rules guarantees an optimal solution in a general MRP environment?

KBB

The total time to process an entire set of jobs at a work center is referred to as

Make-span

Which one of the following is not an assumption of the basic EOQ model?

Quantity discounts can be taken advantage of for large lot sizes.

Practical application of the Theory of Constraints involves the implementation of all of the following steps except

Reduce the capacity at the bottleneck(s).

A negative SPO (Slack per remaining operations) of a job implies that the job is already late

True

Demand for raw materials and component items is derived demand, calculated exactly once a firm has the MPS. Therefore, items contained in manufacturing inventories is called dependent demand inventory.

True

Everything else remaining the same, if EOQ increases, Time Between Orders (TBO) will increase.

True

MRP lot-sizing procedures are designed specifically for the discrete demand case.

True

Order point methods are used to determine appropriate order quantities and timing for individual independent-demand product items that are characterized by random customer demand.

True

Sequencing rules simply prioritize jobs at work centers without reference to the capacity.

True

The Theory of Constraints scheduling is also referred to as the drum-buffer-rope.

True

The Theory of Constraints scheduling loads work centers to full capacity by using finite scheduling.

True

The process with the least capacity is called a bottleneck

True

To provide satisfactory levels of customer service while keeping inventory costs within reasonable bounds, two fundamental decisions must be made about inventory: when to order and how much to order.

True

When ordering costs are relatively small compared to inventory carrying costs, LFL will yield favorable results

True

An inventory system answers two important questions: when to order and how much to order. Which of the following statements correctly explains how a Q,R system (continuous review system) answers these questions?

Under a Q,R rule, a fixed quantity Q is ordered when the inventory position reaches the order point R.

When several jobs arrive at a work center, there is a need for

a system of scheduling and prioritizing

The need for safety stocks can be reduced by an operations strategy which

all of the options are incorrect

Which of the following statements is correct about complete enumeration?

all possible alternatives are evaluated and compared to pick the best solution

Safety stock and safety lead-time are mechanisms to cope with

all the options are valid

Using the Theory of Constraints scheduling logic in simulation mode can help

negotiate achievable delivery dates and meet customer service goals

In Theory of Constraints, which of the following is represented by "rope"?

pull scheduling at the non-bottleneck work centers

Examining realistic, multiple-machine, dynamic scheduling situations is possible by using

simulation

The Stock-out probability is:

the probability that inventory will not be sufficient to meet demand during the cycle
