Aps Modeling And Optimization In Supply Chain With Outsourcing

Application of advanced planning and scheduling into supply chain withoutsourcing can shorten the production cycle and delivery time, improve inventorylevels, equipment utilization and customer service levels. APS as the core ofsupply chain management to enhance the core competitiveness of enterprises is toachieve an important way to solve this problem effectively. Therefore, the businessand academia has been focused the issue. Compared with traditional optimizationalgorithms, the food-chain algorithm has obviously advantages, such as thederivative does not exist, the robustness, with random and overall, suitable forparallel processing. These advantages make the food-chain algorithm suitable forsolving those complex systems with life characteristics, such as supply chain,logistics distribution network, has great potential in the scheduling problems. In thispaper, I will study the problem of APS modeling and Optimization in supply chainwith outsourcing.First, I analysis the features of the problem of APS in supply chain withoutsourcing, describe it in details. Secondly, I choose the minimum makespan——the selected frequently used optimization indexes in mechanical parts processingindustry——to be objective for the model; by analyzing the constraints of theproblem of APS in supply chain with outsourcing: inventory constraints, processprecedence constraints, the machine resource constraints and time constraints oftransportation outsourcing, pointing out that the rules, define parameters andvariables for the mathematical model, then detailedly descripte the issue. To verifythe introduction of two examples to illustrate the APS model can be reasonableunder the outsourcing solution, to determine a delivery order to meet the minimumrequirements of the largest of the optimal completion time scheduling, when theproduction insufficient resources to determine the selection process outsourcing,through the use of outsourcing and effective delivery of products to meet the timerequirements. Finally, food-chain algorithm is applied to the problem APS of supplychain with outsourcing, use the MATLAB to simulate the examples of single andmultiple orders. The results showed that: the food-chain algorithm morepracticalsupply, more in line with engineering applications in solving problems of APS in supply chain with outsourcing.
