just in time Flashcards
What is just-in-time (JIT)?
The right materials are supplied in the right order, in the right amount at the right time
Also known as ‘just-in-time production’ and used synonymously with lean manufacturing.
What is the primary goal of JIT?
Zero inventories across the organisation and its supply chain
This maximizes ROI and utilizes organizational capabilities.
Which company notably copied the JIT system from Japan?
Hewlett-Packard
List three advantages of JIT.
- Elimination of waste in production
- Reduces cost of inventories and storage space
- Stabilized work schedule
What is a disadvantage of JIT regarding demand and supply?
Does not cope well with sudden changes
What technology does smart building asset management use?
Energy-harvesting wireless room sensors
What is the purpose of smart building asset management?
To establish requirements for optimum management of resources
This includes space, personnel, and objects.
How can AI and ML be utilized in construction?
To monitor and prioritize risk on the job site
What role does AI play in safety systems on construction sites?
Tracks real-time interactions of workers, machinery, and objects
What tasks can self-driving construction machinery perform more efficiently?
- Pouring concrete
- Bricklaying
- Welding
- Demolition
What is the potential productivity boost for construction firms through real-time data analysis according to a 2017 McKinsey report?
Up to 50%
What factors can AI predict regarding project management?
Cost overruns based on project size, contract type, and manager competence
What do 3D BIM models need to consider?
Architecture, engineering, mechanical, electrical, and plumbing (MEP) plans
What challenge must be addressed in 3D BIM models?
Ensure that different models from sub-teams do not clash
How can machine learning assist in construction projects?
Identify and mitigate clashes between different models
What is a benefit of using offsite factories in construction?
Components are pieced together by autonomous robots
What type of work do human workers focus on after autonomous machinery completes structures?
Detail work like plumbing, HVAC, and electrical systems
