A product requires 24 separate tasks,and the sum of those task times is 14 minutes.If the cycle time is 2 minutes,then at least 12 workstations will be needed.

Retail layouts are based on the notion that:

Cycle time is the maximum time that the product is allowed at each workstation.

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

What are the advantages and disadvantages of product-oriented layouts?

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 the 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)What is the cycle time required to meet demand? (d)What is the minimum number of workstations required to meet the schedule? (e)Balance this line using the 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.

The work cell layout,a special arrangement of machinery and personnel to focus on the production of a single product or group of related products,is for manufacturing applications and has no relevance to services.

________ layouts deal with low-volume,high-variety production with like machines and equipment grouped together.

A production line is to be designed for a job with four tasks.The task times are 2.4 minutes,1.4 minutes,0.9 minutes,and 1.7 minutes.After line balancing,the largest possible assigned cycle time is ________ minutes,and the smallest possible assigned cycle time is ________ minutes.

A company is designing a product layout for a new product.It plans to use this production line eight hours a day in order to meet a schedule of 400 units per day.The tasks necessary to produce this product are detailed in the table below. a.Draw the network described in the table. b.Without regard to a production schedule,what is the minimum possible cycle time (in seconds)for this situation; what is the maximum? c.What is the required cycle time (in seconds)in order to meet the schedule? d.What is the theoretical minimum number of workstations needed to meet the schedule? e.Balance this line using longest processing time. f.What is the efficiency of the balance obtained in part e?

One guideline for a retail layout is to locate high-draw items around the periphery of the store.

The objective of layout strategy is to:

The layout approach that addresses trade-offs between space and material handling is called the fixed-position layout.
