LP Modelling Framework to Evaluate Lean Implementation Effectiveness

Abstract

Anand Sunder and Ibrahim Raji

We propose a LP modeling approach for 7 types of lean waste, with effects of sub system improvements, including the effects of interdependence of type of waste effects on one another and objective function modeling for optimization and simulation of environmental waste is seen from [1,2]. Khalil [3] extensively explores a weighted measurement criterion between different types of wastes, this however isgood for a high level assessment of lean effectiveness. Tascione V [3], E.Solano [1]. However have bridged the gap by showing a wholistic modelling approach for minimizing waste at a case study level. We formulate our multi objective minimization LP Model as follows:

(Where

defined as the cost per unit waste type)

s.t,

OR

and

Interdependence effects of lean waste types on one another will require models to be built, we plan to evaluate and simulate the actual waste reduction achieved, against the optimum for given systems. A total of 7c₂ or 21 interactions need to be evaluated.
