Cost-time profiling: Putting monetary measures onto value stream maps
(2006-05-20) Rivera Cadavid, Leonardo
The Cost-Time Profile (CTP) is a tool that presents graphically the accumulation, of direct costs on a product as it moves through the manufacturing process. CTP incorporates the time dimension, to the cost accumulation, and the area under the CTP curve is the Cost-Time Investment (CTI), which is a measure of the investment of resources on the manufacturing of the product. In this paper, a general overview of the CTP, its construction, applications and future research directions are presented.
Leanness score of value stream maps
(2007-05-19) Wan, Hung Da
A Value Stream Map (VSM) allows lean practitioners to visualize the performance and conditions of manufacturing systems. While creating visibility for improvement plans, a measure of overall leanness level is not inherent in the map. This research proposes a methodology to measure the overall leanness of a VSM considering Cost, Time and output Value. Value-added and non-value-added investments are identified to quantify the level of leanness. Using the Data Envelopment Analysis technique, the leanness measure delivers a self-contained, unit-invariant score of the mapped system to support decision making on continuous improvement.
