Mathematical theory of improvability for production systems [PDF]

open access: yesMathematical Problems in Engineering, 1995
A mathematical model for continuous improvement processes in production systems is formulated. Both constrained and unconstrained cases are addressed. A solution for the case of a serial production line with finite buffers and a Bernoulli model of machines reliability is given.
