Op Management Module 3

In the context of operations management, which of the these refers to the assignment of start and completion times to particular jobs, people, or equipment

Scheduling

A requirement of two-resource sequencing rule is that

each job must be processed first on the first resource and then on the second

Each customer order in the cabinet shop was meticulously tracked by employees. They knew who ordered and when the order was placed. They also recorded when the job was promised and delivered. Using the delivery date and the order date, the employees were able to compute

the flow time

A profession office uses an appointment time interval of 15 minutes to schedule customers. What should office staff do if they know a particular customer’s needs exceed this time interval

Use a multiple of 15 minute, like 30 or 45 minutes for this customer

3 customers dropped off their dry cleaning at 8:00 Monday morning, and the operator promised each one a different ready time. The 3rd and final pick-up time was to be 5:30 pm Monday. For 3 jobs, 9.5 hours represents which of the following

Makespan

In a two-resource sequencing problem

the goal is to minimize makespan

IN the context of sequencing, the difference between the completion time and the due date of a job is known as

lateness

Why are front-office operations, like the reception and intake area of an emergency clinic, difficult to schedule in comparison to a manufacturing operation

Because both customers and service providers participate in service creation and delivery

When scheduling staff to match anticipated customer demand, the first step is to

convert customer demand to a capacity measure (i.e. the number of staff required)

Mara, a new assistant professor, eyeballed her teaching assignment for the fall semester She had two section of operation management at 8 am Mon-Wed and Tues-Thurs. This is Mara’s

Schedule

In the context of operations management, triage nurses deciding on the order in which emergency patients are to be treated is an example of

Sequencing

The 4 × 100 meter relay was to begin at 2 pm. At the team breakfast, Coach Fowler told the team the order of the runners. Coach has established a

Sequence

Devin’s scheduling software showed that the customer order wasn’t late, but curiously, the calculated was identical to the lateness. How tardy is the job

0

Bar charts are used to

Monitor planned schedules

In the context of sequencing, the earliest due date (EDD) rule

minimizing the maximum jobs past due

In the context of sequencing, the time needed to process a given set of jobs is called

makespan

In the context of sequencing, the rule that minimizes the average lateness of a set of jobs is the

shortest processing time rule

In the context of sequencing, which of these refers to the amount of time by which the completion time exceeds the due date of a job

tardiness

In the context of sequencing, the shortest processing time (SPT) rule tends to

minimize work-in-process inventory

What is perhaps the most effective way to increase speed and response

Synchronize the entire value chainW

Which of the following is an example of waste is organization

Planned product obsolescence

Lean has a goal of zero waste in all value-creation processes and

all support processes

In the airline industry, short setup and turnaround time translate into

higher asset utilization

WHich of these is focused on ensuring that operating systems will perform their intended function reliably

total productive mantience

Southwest uses only one type of aircraft- the Boeing 737. Which of 5S principles isa t work with this tactic

Standardize

Which type of system produces finished goods inventory is advance of customer demand using a forecast of sales

Push

Geeky Gadgets Company’s suppliers was having a year-end price reduction on a few components on Latoya stucked up on a 6 month supply of one of the sales items. As jeffery was putting them into storage, he wondered whether this was the best use of the firm’s money, citing the Toyata waste of

inventory

Lean is focused on

efficiency by reducing waste and improving process flows

Drive-in -style motors follows a traditional manufacturing systems It produces a fixed number of cars every month. It is now planning to switch to a system of manufacturing where workers go to the source of required pairs and withdraw them based on requirements. In this scenario, which of the following is most likely to occur if they implement this plot

the component parts and subassemblies will be replenished only when needed

Which of the following is a similarity between lean production and Six sigma

Both are driven by customer requirements

Southwest is one of the few airlines encouraging passengers to carry their luggage on the plan which Lean’s wastes is this an example of

Processing

Which system is one in which employees at a given operations go to the source of repaired parts, such an matching in subassembly and withdraw the unit as they need them

A pull system

In comparison with both lean thinking and six sigma, the theory of constraints

is more reliant on value stream mapping and finanical measures

Which action would be considered a process simplification for a service business

Completing forms online before one’s appointment

In the context of the 5s principles, which of these terms refers to ensuring that each item in a workplace is in the its proper place or identified as unnecessary and removed

sort

At southwest airlines all employees cooperate to ensure timely takoffs and landings, even to the points of the pilots helping load luggage what principle does this embody

Single minute exchange of dies (SMED)

In the context of lean tools and approaches which one of the components of the 5s principles renders to a clean work area

shine

Developing formal producers and practices to create consistency in how things are done falls under which 5s

Standardize

Which of the following is not true about lean principles

They are always transferable to front-office services that involve high customer contact

The equation used to calculate the number of Kanban cards required in a system, where o< donotes

a form of safety stock

One difference between six sigma, the theory of constraints and Lean is

six sigma requires a more analytical, measurement driven approach

In the context of lean tools and approaches, which of these are indicators for operating activities that are placed in plain sight of all employees so that everyone can quickly and easily understood the status and performance of the work system

visual contorls

In the context of the 5s principles which of the following means to keep a process going through training communication, and organizational structures

sustain

When queues build up in between process steps, there is more work-in-process inventory and

longer lead times
