Theory of Constraints (TOC)

Theory Of Constraints

Theory of Constraints is composed of two methods of management. Critical Chain (C/C) project management plans for the known (Actual Touch Time) and buffers for the unknown. (Murphy)

Simplified Drum Buffer Rope (S-DBR) component management compliments Critical Chain so that components are completed in time for installation by using buffers also.

GOALS: 

Meet customer requirements for Cost, Schedule, and Quality
Increase Throughput 
Decrease Costs
Decrease Work In Process (WIP) 
Reduce Repair Cycle Time (RCT)

Conducted Maintenance Center-wide training 
Created a new shop floor schedule (Critical Chain) for major end items 
   –  Mechanics’ input on process hours 
   –  Removed safety time 
   –  Placed a project buffer at the end 
Stopped multitasking 
Changed to Pull-System 
Implemented Simplified-Drum Buffer Rope for components
