Optimal capacity and operation of deteriorating chemical production service facilities Academic Article uri icon


  • In this paper, we propose a model for the allocation of identical service facilities forrestoring deteriorating production (e.g., batch chemical) processes. The problem is motivatedby and solved for the new Dead Sea Works Ltd. magnesium plant. The production systemconsists of a number of identical production cells, each requiring a set of service tasks. Themodel determines both the optimal number of servers and the service rate allocated to eachservice task. The model takes into account the breakdown and repair processes for the servicefacilities. Thus, the optimal service rate is calculated and assigned according to the randomnumber of available service facilities. Insightful results are provided by both analytical andnumerical sensitivity analysis. Copyright Kluwer Academic Publishers 1999
