Exam 9: Layout Strategies

An insurance claims processing center has six work centers,any of which can be placed into any of six physical departmental locations.Call the centers 1,2,3,4,5,and 6,and the departments A,B,C,D,E,and F.The current set of assignments is A-3,B-1,C-6,D-2,E-4,and F-5. The (symmetric)matrix of departmental distances,in meters is The matrix of work flow (estimated trips per day)is among centers The firm estimates that each trip costs approximately $4. a.What is the cost of the current assignment? b.Use trial-and-error to find one improved assignment. c.What is that assignment,and what is its cost?

Retail layouts thrive on the notion that

An assembly line consists of 21 tasks grouped into 5 workstations.The sum of the 21 task times is 85 minutes.The largest assigned cycle time is 20 minutes.The efficiency of this line is

Heuristics are problem-solving procedures that mathematically optimize the solution.

An assembly line consists of 158 tasks grouped into 32 workstations.The sum of all task times is 105 minutes.The largest assigned cycle time is 4 minutes.The efficiency of this line is approximately

The main goal of retail layout is

The concept of customizing in a warehouse layout

An airport is trying to balance where to place three airlines.The distance between terminals and the number of trips that travelers make between airlines per day are listed.Find the assignment that minimizes the distance travelers must walk.

________ refers to the physical surroundings in which a service takes place,and how they affect customers and employees.

Which layout's main objective is to equalize the task time for each station?

In a product-oriented layout,the process of deciding how to assign tasks to workstations is referred to as

A company is trying to balance production between 3 workstations on an assembly line.Currently there are 5 tasks that need to be performed.These tasks,ABCDE,have required times of 2 minutes,4 minutes,1 minutes,3 minutes,and 10 minutes respectively.The assembly line needs to produce 40 units per day to meet demand and can work for up to 8 hours each day. A.What is the required cycle time? B.What is the theoretical minimum # of workstations? C.Assign the tasks according to shortest task time. D.Is there a better way to divide the work than in Part C?

Cyclone Appliances has developed a new European-style convection oven that will be made on an assembly line.The schedule requires 80 ovens in an 8-hour day.The assembly includes seven tasks.The table below indicates the performance time and the sequence requirements for each task. a.What is the cycle time for this assembly operation? b.What is the theoretical minimum number of workstations? c.Draw the precedence diagram.

A(n)________ is a special product-oriented arrangement of machines and personnel in what is ordinarily a process-oriented facility.

McDonald's "Made for You" kitchen system represents a strategic layout decision even though an obvious benefit of the system is a dramatic reduction in the inventory of food prepared in advance.

What is cross-docking? Why is it appropriate for some forms of warehouse layout?

What is the primary reason why retailers tend to locate high-draw items around the periphery of the store?

A disadvantage of product-oriented layout is that

Servicescape refers to the physical surrounding in which the service is delivered.

Hemo-tech,Inc. ,a biomedical technology and research laboratory,produces a standard blood filtering device on an assembly line basis.Six basic tasks are performed along an assembly line.The time to perform each task and the tasks that must immediately precede each task are in the table below.Twenty pumps per 450-minute day must be produced by the assembly line. a.Draw the network diagram of the precedence relationships. b.Identify the absolute minimum and maximum cycle times. c.How many workstations are required to meet the schedule? d.What is the cycle time required to meet demand? e.Balance this line using most following tasks heuristic. f.What is the efficiency of the line obtained in part e? g.Can the efficiency of this solution be improved? Explain.
