Topic 5 - Short Term Operations Scheduling
Question | Answer |
---|---|
what is short term operations scheduling? | activities dedicated to program, monitor & evaluate ST tasks to achieve MPS efficiently considering available capacity |
what are its basic functions? | - evaluate & control orders pending to be produced according to materials planning - operations scheduling (priorities) - monitor evolution of orders in progress - control operations development - control capacity - provide feedback |
what are the fundamental objectives? | 1. service level = EFFECTIVENESS 2. minimum costs = EFFICIENCY (low inventory levels, avoid waiting queues, minimise idle time) |
what are the fundamental activities? | 1. job allocation 2. sequencing 3. detailed scheduling 4. despatch |
what are job allocation techniques | = trial & error (ganntt chart) = optimiser methods (Hungarian methods) = heuristic solutions (indices) |
what are sequencing techniques? | line production of big lots = one machine (KAUFFMAN) = 2 or more machines (JACKSON & JOHNSON) |
what are 3 types of configuration? | 1. Project (different, specific, unique) 2. Continuous (chain, standardised product, EFFICIENT NOT FLEXIBLE) 3. Lot (same facilities, diff products) = PRODUCTION LINE - big lot, same product, skip operations = JOB SHOP - variety, small lot, flexible |
