Abstract:

Generally the decisions in different levels of supply chain are considered independently while the feasibility of operational decisions greatly depends on the accuracy of forecasts in strategic level. In this study, a production scheduling problem is considered integrated with a capacity planning problem. This problem addresses a coordination issue in supply chain area between a tactical and an operational decision process. A flow shop environment with resource allocation are regarded in which the processing time of a job depends on the amount of several types of additional resources should be assigned to that job in planning stage. In order to minimize a combination of maximum completion time and required amount of resources, a decomposition approach is suggested that strives to tackle the main problem via two subproblems: job sequencing problem and capacity planning problem. A hybrid evolutionary algorithm is then devised to achieve the accurate schedule of jobs as well as appropriate allocation of resources.
