P 48 000 r 70 b 0.514573 We coded the models as mixed integer nonlinear programming problems in AMPL language and solved them using the MINLP solver on the Neos solver website http www.neos-server.org neos solvers minco MINLP AMPL.html . Tables 17 through 31 provided are the results obtained for each scenario presented in tables 2 through 16 respectively. For example Table 17 contains the result of the parameter values in Table 2 for the 5 different models namely Lot-for-Lot SSMD MSMD Modified MSMD I and Modified MSMD II . The metrics used for each model are aggregate TC per year Q N D Q m and N m . The D Q gives the frequency of orders per year while N m gives the frequency of setups per .
