Facility layout and scheduling: In which layout is production scheduling simpler, enabling high output and high labour efficiency?
-
AProduct (line) layout
-
BProcess (functional) layout
-
CFixed position layout
-
DCombination of line and process layout
Answer
Correct Answer: Product (line) layout
Explanation
Introduction / Context:Facility layout decisions impact throughput, scheduling, material handling, and labour productivity. A product (line) layout arranges resources in the sequence of operations for one or a few high-volume products, whereas process layouts group similar machines, and fixed position layouts keep the product stationary.
Given Data / Assumptions:
- The goal is to simplify scheduling and achieve high output with high labour efficiency.
- Products are standardized or have limited variants.
- Demand is steady enough to balance the line.
Concept / Approach:In a product layout, each workstation performs a fixed, repetitive task; jobs flow in a single, predefined path. Line balancing and takt-based planning simplify scheduling. Workers specialize, changeovers are minimized, and material flow is streamlined, raising output and labour efficiency compared with process or fixed-position layouts.
Step-by-Step Solution:
Identify the need for simple scheduling and high volume.Map this need to a stable sequence of operations suited to a line.Recognize that product layout minimizes routing complexity and WIP.Conclude that product (line) layout best satisfies the criteria.Verification / Alternative check:Empirical results in assembly lines (e.g., consumer goods, automotive subassemblies) show predictable schedules and high throughput when demand is stable.
Why Other Options Are Wrong:
- Process layout: flexible but complex routing and scheduling; higher WIP.
- Fixed position layout: suited for large projects; scheduling is component/crew oriented and complex.
- Combination layout: useful when needed, but typically more complex to schedule than a pure line.
Common Pitfalls:Trying to use a line layout for highly customized products; ignoring balance losses and bottlenecks that reduce theoretical efficiency.
Final Answer:Product (line) layout
