A job has 5 days of processing time left to do before completion, and today is the 10^th day of the month. If the job is due on the 14^th day of the month, what is its critical ratio?

Assume you are sequencing jobs using Johnson's rule. There are three jobs called A, B, and C. The first step is assembling and the second step is painting. Job A requires 3 hours to assemble and 6 hours to paint. Job B requires 7 hours to assemble and 2 hours to paint. Job C requires 4 hours to assemble and 1 hour to paint. The objective is to minimize the total processing time of all jobs, using Johnson's rule. What is the correct sequence to process the jobs?

Which of the following priority rules used in scheduling the sequence of production is calculated as the slack time remaining in the schedule divided by the number of remaining operations, with the smallest value being run first?

A shop-floor control system is a system that uses data from the shop floor as well as data processing files to maintain and communicate status information on shop orders and workcenters.

The "dollar days" inventory measurement results from a complex algorithm used to compute individual units of inventory and their respective ordering and holding costs.

One way to find a bottleneck is to run a capacity resource profile.

JIT requires vendors to be located nearby. When compared to synchronous manufacturing, this is viewed as an advantage of JIT.

According to the theory of constraints, which of the following is a kind of time that makes up the cycle time in production?

Which of the following is a negative aspect of JIT compared to synchronous manufacturing?

The objectives of workcenter scheduling include which of the following?

According to the theory of constraints, which of the following is a financial measurement that can be used to measure the firm's ability to make money?

A process batch should be no larger than the transfer batch.

Rather than try to adjust the master production schedule to change resource loads, it is more practical to control the flow at each bottleneck or CCR to bring capacities in line.

When work has been scheduled in a shop that does not have sufficient resources to complete the schedule on time, the system that generated the schedule is called which of the following?

The objective of Johnson's rule for job sequencing is to minimize flow time from the beginning of the first job until the completion of the last job.

Scheduling hourly work times using the "first-hour principle" ensures that no excess labor will be used during the work shift.

Priority rules are the rules used to obtain a job sequence in production scheduling.

Buffer inventory in front of a bottleneck is called a time buffer.
