The Use of LP Simplex Method in the Determination of the Minimized Cost of a Newly Developed Core Binder
Journal Title: Leonardo Electronic Journal of Practices and Technologies - Year 2007, Vol 6, Issue 11
Abstract
A new binder system has been developed which is based on manihot esculenta and cement. The new binder system is expected to be an alternative to Urea formaldehyde furfuryl alcohol binder system commonly used in the foundry for core making; it is a cold setting binder system. The cost factor is one of the reasons for the development of this new binder system, therefore LP simplex method model was used in the determination of the minimized cost using this newly developed binder system for core making. The result showed that the cost was $1.57/1kg of core mixture as against $5 for using urea formaldehyde furfuryl alcohol binder system. The work also revealed that strict adherence to the compositional constraints is very important since any change in either of the constraints would lead to a change in the total cost of producing the core mixture and consequently too, a change in the properties of the cores produced using the core mixture.
