WGU C720 Competency 6 Operating Efficiency exam with 100% correct answers

Just-in-time (JIT) manufacturing methodology aimed primarily at reducing flow times within production systems as well as response times from suppliers and to customers by receiving ordering and receiving inventory when ready for use or just in time for use What are the fundamental concepts of JIT? - JIT allows materials to flow in an assembly process similar to a continuous flow process - uses general purpose machinery - produces in small batches or small lot sizes - uses a pull system - uses process facility layout Just-in-Time 2 (JIT II) relationships with suppliers are further strengthened beyond vendor managed inventory in which the supplier places a representative on the customer's site that is dedicated to the customers products only Push System moves materials through the process operations based on a schedule Pull System moves materials through a system to work-stations as they are needed Value Stream Mapping a technique used to analyze the flow of materials, ideas, and information to understand how processes function Group Technology (GT) production system The idea behind GT is that each part follows the same essential processing sequence. By keeping similar parts together, setup time is reduced, and the flow of materials is not interrupted. If excessive time is taken for the setup, then the flow of materials will be stopped—causing downstream processing operations to pause until the flow resumes. If "upstream" operations continue unchecked, unnecessary inventory will build up in the system, much as water builds up when a dam is placed across a river Kanban Japanese word that can refer to a sign or a marker and means "visible record." Conveyance kanban (C-kanban) is an authorization to move a container of parts or materials. Without it, nothing can be moved Production Kanban (P-kanban) is used to authorize the production of parts or subassemblies Single Card Kanban must follow what rules? - containers holding parts can be moved only when a card is attached - standard containers must always be used Electronic Kanban (E-kanban) is a digital signal or electronic authorization to move a container of parts or replenishment of materials Dual Card Kanban System combines C-kanban and P-kanban Final Assembly Schedule an exact statement of the final products that are to be assembled. Level Assembly Schedule means that the number of units of each end product produced at a time is as small as possible, and that total production of each matches average demand during the scheduling horizon Cycle Time a measure of how often a particular product is made
