The results from the model propose a schedule to purchase raw \r\nmaterial from different suppliers to the various  factories considered, lateral stock transshipments, \r\nshipments to customers and various operations required for product assembly. Different alternative \r\noperations (product substitution, alternative procurement and transport operations), considering lead \r\ntimes, are contemplated. Specific constraints, such  as space availability in each plant and the two \r\nbacklog types, are considered. A novel approach based on the stroke concept is applied to the MILP \r\nmodel to consider alternatives. Since the latest MILP optimizers are not always available, a specific \r\nprocedure to solve the case study based on the graph theory is proposed. Moreover, thanks to this \r\nconcept, the algorithm proposed determines all the feasible solution<\/pre>\n","protected":false},"excerpt":{"rendered":"<div class=\"mh-excerpt\"><p>http:\/\/www.usc.edu\/dept\/ise\/caie\/Checked%20Papers%20%5Bruhi%2012th%20sept%5D\/word%20format%20papers\/REGISTRATION%20PAID%20PAPERS%20FOR%20PROCEEDINGS\/pdf\/94%2012%20MILP%20MODEL%20FOR%20SOLVING%20THE%20SUPPLY%20CHAIN%20OPERATIONS%20SCHEDULING%20PROBLEM%20WITH%20ALTERNATIVE%20OPERATIONS%20CONSIDERING%20DEL.pdf This paper addresses a mixed integer linear programming model for operations lot-sizing and scheduling (assignment and sequencing) in the supply network of a European company which assembles customized machine tools through several geographically distributed factories and delivers them to the customers&rsquo; factory.
