BU385 Final: Final Review
Document Summary
4 types of process types from high to low equipment flexibility: Job shop: low quantity, customized g/s; intermittent; must schedule job to meet due dates & max. utilization. Batch process: moderate quantity and variety of g/s desired; intermittent; equipment/skill doesn"t have to be as flexible/high as ^; must schedule batches to meet planned production/demand while using resources at high level. Repetitive process: high quantities of standard g/s; low flexibility/skill; production line (sequenced machines & workstations), assembly line (production line, parts added sequentially); challenge: capacity balance, technology management, quality, materials. Process (functional) layout: group similar activities together by process/function performed; less vulnerable to shutdown by mechanical failure/absenteeism, lower maintenance costs, low equipment utilization rates, high costs; Automation: low variability, reduction of variable costs, improve productivity/quality; high initial cost, less flexible. Flexible automation: uses equipment more customized than programmable; requires less changeover time = cont. operation of equip. and product variety without need to produce in batches; e. g. machining center.
